Cerebellar Ataxia-Areflexia-Pes Cavus-Optic Atrophy-Sensorineural Hearing Loss Syndrome

Cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome is usually called CAPOS syndrome. It is a very rare genetic brain and nerve disorder. It affects balance and walking (cerebellar ataxia), reflexes (areflexia), the shape of the feet (pes cavus), the optic nerve in the eyes (optic atrophy), and the inner ear nerves for hearing (sensorineural hearing loss). Genetic Rare Disease Center+1

Cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome is usually called CAPOS syndrome. It is a very rare, inherited brain and nerve disorder caused by changes in a gene called ATP1A3. This gene helps brain and nerve cells move salts in and out, which is important for normal electrical signals. When the gene does not work properly, parts of the brain that control balance, vision, and hearing do not work normally. NCBI+2The JCN+2

The name CAPOS comes from its main signs: cerebellar ataxia (clumsy, shaky movements and poor balance), areflexia (very weak or missing tendon reflexes), pes cavus (high-arched, stiff feet), optic atrophy (damage of the optic nerve that slowly reduces vision) and sensorineural hearing loss (permanent inner ear or nerve-type hearing loss). Symptoms often begin in babies or young children after a fever illness, and later the child is left with long-term balance, vision, and hearing problems. MalaCards+2NCBI+2

CAPOS syndrome usually starts in infancy or early childhood, often between 6 months and 5 years of age. A typical pattern is that a child gets a fever from an infection and, during or just after the fever, suddenly develops trouble walking, weakness, and other brain symptoms. These episodes are called ataxic encephalopathy (ataxia plus brain dysfunction). NCBI+1

After the fever clears, some problems, like severe confusion, may improve, but many children are left with long-term issues. These may include problems with coordination, high-arched feet, poor or absent reflexes, slowly worsening vision from optic nerve damage, and progressive hearing loss. Symptoms may flare again with new fevers or other body stresses, such as childbirth later in life. Genetic Rare Disease Center+1

CAPOS syndrome is caused by a change (mutation) in a gene called ATP1A3, which gives the instructions for part of a sodium-potassium pump (Na⁺/K⁺-ATPase) in brain and nerve cells. Most known patients have the same mutation called p.Glu818Lys. This faulty pump makes nerve cells more sensitive to stress, especially high body temperature during fever, so symptoms appear in attacks. Europe PMC+1

Because CAPOS is very rare and can look like other childhood brain or nerve diseases, many children are first misdiagnosed. Careful history, neurological and eye examination, hearing tests, brain imaging, and finally genetic testing are usually needed to be sure of the diagnosis. Lippincott Journals+1

Other names

Doctors and researchers use several other names for this syndrome. All of them describe the same basic condition, and most are shortened to “CAPOS”: Rare Diseases+1

• CAPOS syndrome – the most common short name. Rare Diseases+1

• CAPOS (cerebellar ataxia, areflexia, pes cavus, optic atrophy, sensorineural hearing loss) syndrome – full expanded name. Wikipedia+1

• Cerebellar ataxia-areflexia-pes cavus-optic atrophy-sensorineural hearing loss syndrome – same as above, written in full. NCBI+1

• Cerebellar ataxia, areflexia, pes cavus, optic atrophy and sensorineural hearing loss – variant wording used in genetic and rare disease databases. NCBI+1

• CAPOS/CAOS syndrome – sometimes used when pes cavus is absent (“CAOS” = cerebellar ataxia, areflexia, optic atrophy, sensorineural hearing loss). PubMed+1

Types

Because CAPOS is so rare, there is not a long list of official “types”. However, doctors have noticed a few patterns or clinical forms that can be thought of as sub-types. Lippincott Journals+1

Classic CAPOS syndrome is the best-known form. These patients have fever-triggered episodes of ataxia and brain dysfunction in early childhood, followed by long-lasting cerebellar ataxia, areflexia, high-arched feet, optic atrophy, and sensorineural hearing loss. They usually carry the p.Glu818Lys mutation in ATP1A3. Lippincott Journals+1

CAPOS / CAOS without obvious pes cavus describes patients who have the main brain, eye, and hearing problems, but do not clearly show the high-arched feet. Because other features are very similar and the same ATP1A3 mutation is present, many experts see CAOS as a variant of CAPOS rather than a separate disease. PubMed+1

Atypical or expanded CAPOS spectrum includes patients with CAPOS features plus extra problems, such as seizures, dystonia, or cardiac conduction issues. In some reports, episodes may start slightly later than usual or may be triggered not only by fever, but also by strong heat or other stresses. These cases show that CAPOS belongs to a wider group of ATP1A3-related disorders with overlapping signs. public-pages-files-2025.frontiersin.org+2Frontiers+2

Causes

The main cause of CAPOS syndrome is a missense mutation in the ATP1A3 gene, most often the change c.2452G>A (p.Glu818Lys). This mutation alters one building block in the sodium-potassium pump protein, which disturbs the balance of sodium and potassium ions across the nerve cell membrane and makes neurons more vulnerable to heat and metabolic stress. Europe PMC+1

1. Autosomal dominant inheritance
   CAPOS follows an autosomal dominant pattern, meaning one changed copy of the ATP1A3 gene is enough to cause the condition. A child can inherit this mutation from an affected parent, and each child of an affected person has a 50% chance of receiving the mutation. malacards.org+1

2. De novo (new) ATP1A3 mutations
   In many reported families, the mutation appears for the first time in the affected child and is not present in either parent. This is called a de novo mutation and happens by chance when egg or sperm cells form or very early in embryo development. PubMed+1

3. Na⁺/K⁺-ATPase dysfunction in neurons
   The ATP1A3 protein helps pump sodium out of and potassium into nerve cells. When this pump does not work well, the cells have trouble keeping a stable electrical balance, especially during stress like fever. This leads to abnormal firing of neurons in the brain, optic nerve, and hearing pathways, causing the typical symptoms. Beyond the Ion Channel+1

4. Selective vulnerability of cerebellum and brainstem
   ATP1A3 is highly active in certain brain regions, including the cerebellum and brainstem. These regions help control balance, eye movements, and vital functions. Because they rely heavily on this pump, they are especially sensitive to ATP1A3 mutations and show early signs such as ataxia and encephalopathy during fevers. NCBI+1

5. Fever-triggered metabolic stress
   Fever increases body temperature and metabolic demand. In children with ATP1A3 mutations, this extra stress is enough to “unmask” the pump weakness and produce sudden ataxic episodes and brain dysfunction. This is why most CAPOS attacks happen during or after infections that cause fever. PMC+2Genetic Rare Disease Center+2

6. Infection-related inflammation
   Viral or bacterial infections that cause fever also release inflammatory chemicals in the body. These substances can affect the brain’s energy use and the way ion channels work. In CAPOS, this may further disturb the already fragile sodium-potassium balance in neurons and help trigger attacks. PMC+1

7. Pregnancy and childbirth as triggers
   Some adults with CAPOS have attacks during late pregnancy or around delivery. The body’s huge hormonal shifts, fluid changes, and the stress of labor may all add strain on the nervous system, exposing the weakness caused by the ATP1A3 mutation and leading to new episodes. Genetic Rare Disease Center+1

8. Ambient heat and overheating
   Case reports describe patients whose spells of vertigo, ataxia, and hearing fluctuations are brought on by hot environments or heat exposure, even without fever. External heat raises body temperature and can have similar effects on the sodium-potassium pump as internal fever. Experts at U of M+1

9. Physical stress and exhaustion
   Hard physical activity, prolonged lack of sleep, or general exhaustion may reduce the brain’s energy reserves. In a person with reduced ATP1A3 function, this can make neurons struggle to keep ion balance and could contribute to worsening of symptoms during or after stressful periods. This is inferred from what is known about ATP1A3-related disorders and stress sensitivity. Beyond the Ion Channel+1

10. Other ATP1A3-related phenotypes in the family
    In some families, ATP1A3 mutations cause different but related disorders, such as alternating hemiplegia of childhood or rapid-onset dystonia-parkinsonism. The shared gene problem shows that the mutation is the root cause, while the specific clinical picture (like CAPOS) depends on how and where the pump defect affects the brain. NCBI+2Frontiers+2

11. Genetic background and modifiers
    Not all people with the same ATP1A3 mutation have identical severity. Other genes in the person’s genome, as well as epigenetic factors, may change how strongly CAPOS features appear. This idea comes from reports showing different symptom patterns in different families with the same mutation. public-pages-files-2025.frontiersin.org+1

12. Age-related neural development
    CAPOS episodes tend to start in infancy or early childhood, when the brain and its connections are still maturing. During this time, neurons are especially sensitive to changes in ion handling and energy supply, so the ATP1A3 defect can have a stronger effect and lead to acute attacks. NCBI+1

13. Chronic stress on optic nerve fibers
    Over time, repeated or prolonged ionic imbalance and metabolic stress may damage the long fibers of the optic nerve. This leads to optic atrophy and progressive vision loss, which is a core part of CAPOS and often continues to worsen slowly after the first episodes. EyeWiki+1

14. Damage to cochlear and brainstem auditory pathways
    Hearing loss in CAPOS is due to injury of the inner ear hearing nerve and brainstem auditory pathways, rather than problems with the outer or middle ear. Studies show abnormal auditory brainstem responses even when outer hair cells still work, pointing to a neural cause linked to ATP1A3 dysfunction. ScienceDirect+1

15. Peripheral nerve involvement and areflexia
    Reduced or absent reflexes suggest that peripheral nerves or their connections in the spinal cord are affected. The Na⁺/K⁺-ATPase is also important in peripheral nerves, and ATP1A3 mutations may disturb their function, helping explain the persistent areflexia in most patients. Lippincott Journals+1

16. Foot deformities (pes cavus) from long-term imbalance
    High-arched feet likely develop because of long-standing imbalance and weakness of specific foot muscles controlled by damaged nerves. Over years, abnormal muscle pull shapes the bones and soft tissues, and this is seen in a subset of CAPOS patients. Lippincott Journals+1

17. Recurrent encephalopathy episodes
    Each fever-linked encephalopathy episode temporarily worsens brain function. Repeated episodes may cause cumulative injury to certain pathways, adding to long-term ataxia, vision loss, or hearing impairment. This pattern of repeated attacks followed by incomplete recovery is common in ATP1A3 disorders. PMC+2Lippincott Journals+2

18. Possible mitochondrial stress
    Although CAPOS is not a mitochondrial disease, the sodium-potassium pump consumes much of the brain’s energy. A faulty pump can put extra strain on cell energy factories (mitochondria), especially during fever, leading to further cellular stress and symptoms. This mechanism is suggested by biochemical understanding of ion pumps and energy use. Beyond the Ion Channel+1

19. Overlap with other ATP1A3 phenotypes
    In some patients, features overlap with alternating hemiplegia or rapid-onset dystonia. This suggests that small differences in how the mutation works in different brain networks may “push” the presentation toward CAPOS or toward another ATP1A3-related picture, highlighting the gene as the shared root cause. Frontiers+1

20. Rarity and under-recognition
    Because CAPOS is extremely rare, many cases may be missed or misdiagnosed as other conditions like viral encephalitis or Guillain-Barré syndrome. Delayed diagnosis does not cause CAPOS, but it can delay supportive care and genetic counseling, which are important for managing the underlying genetic cause. www.elsevier.com+1

Symptoms

An individual child does not need to have every symptom listed below, but most will have many of them. The combination and timing of symptoms help doctors suspect CAPOS. Genetic Rare Disease Center+2Wikipedia+2

1. Cerebellar ataxia (poor balance and coordination)
   Children often suddenly become unsteady, stagger when walking, or cannot stand or walk during an attack. Even between attacks, they may have a wide-based, clumsy gait and trouble with fine coordination, like picking up small objects. NCBI+2Genetic Rare Disease Center+2

2. Areflexia (loss of reflexes)
   When the doctor taps the knees or ankles with a reflex hammer, little or no reflex is seen. This usually starts during the first episode and often stays for life. Parents do not notice this at home, but it is an important clue on neurological exam. Lippincott Journals+1

3. Pes cavus (high-arched feet)
   Some children develop very high arches and sometimes clawed toes. This change develops slowly over years and can cause pain, difficulty finding shoes that fit, or extra tripping because the foot does not sit flat on the ground. Lippincott Journals+1

4. Optic atrophy (optic nerve damage)
   The optic nerve, which carries signals from the eye to the brain, becomes thin and pale over time. Vision may blur, central vision may become worse, and in severe cases, serious visual impairment or even legal blindness can develop. EyeWiki+1

5. Sensorineural hearing loss
   Hearing problems often appear in early childhood but are usually not present at birth. They may start suddenly after a fever, then slowly worsen. The hearing loss comes from damage to the inner ear nerve pathways, so ordinary ear infections alone cannot explain it. ScienceDirect+2ScienceDirect+2

6. Acute encephalopathy (brain dysfunction during attacks)
   During a fever-triggered episode, children may become unusually sleepy, confused, or hard to wake. Some may have reduced awareness or even briefly lose consciousness or fall into a coma. These symptoms are usually temporary but can be frightening. Genetic Rare Disease Center+2Wikipedia+2

7. Hypotonia and flaccidity (low muscle tone)
   During attacks, muscles can become floppy. Babies and toddlers may feel “like a rag doll” when held. This low tone can make it hard to sit or stand, but it often improves after the episode, although some mild ongoing low tone may remain. Genetic Rare Disease Center+1

8. Abnormal eye movements (nystagmus and strabismus)
   The eyes may move quickly back and forth (nystagmus) or turn inward or outward (strabismus), especially during an episode. These movements show that brain areas controlling eye position and coordination are affected. Genetic Rare Disease Center+1

9. Dysarthria (slurred or unclear speech)
   Some children have trouble speaking clearly, especially during or after attacks. Their speech may sound slow, slurred, or “thick,” reflecting poor control of the muscles of the mouth and tongue, which is common in cerebellar disorders. Genetic Rare Disease Center+1

10. Dysphagia (swallowing difficulty)
    Eating and drinking can become hard during acute episodes. Children may choke, cough, or take a long time to swallow. This is usually temporary but shows that the brainstem and coordination of swallowing muscles are affected. Genetic Rare Disease Center+1

11. Weakness or paresis
    Some children show real muscle weakness in their arms or legs, beyond balance problems. They may not be able to stand or lift their arms normally. This weakness can mimic conditions like Guillain-Barré syndrome but is part of the CAPOS attack pattern. www.elsevier.com+1

12. Persistent gait problems
    Even outside acute attacks, many children and adults have long-term gait difficulties. They may walk with a wide base, have trouble running or climbing stairs, or tire easily when walking long distances. Lippincott Journals+1

13. Vertigo and balance spells
    Some patients report episodic vertigo, feeling that the room is spinning, along with worsened ataxia. These spells can be triggered by heat or fever and may occur on top of already existing balance problems. Experts at U of M+1

14. Cognitive or learning difficulties (in some patients)
    Most children with CAPOS have normal intelligence, but some reports mention mild learning problems or attention difficulties. These may result from repeated brain stress during attacks or from the underlying genetic change affecting brain circuits. ScienceDirect+1

15. Fatigue and reduced stamina
    Chronic problems with balance, vision, and hearing, plus the effort needed to compensate for them, can make people with CAPOS tire more easily. Fatigue may worsen after minor infections or stressful events, even without a full attack. visualdx.com+1

Diagnostic tests

Diagnosing CAPOS syndrome involves putting together the story (history), physical and neurological exam findings, and several tests. The aim is to show the typical pattern and to rule out other diseases. Genetic testing for ATP1A3 confirms the diagnosis. Genetic Rare Disease Center+2NCBI+2

Physical examination tests

1. General neurological examination
   The doctor checks mental status, cranial nerves, strength, sensation, coordination, and gait. In CAPOS, they often find ataxia, abnormal eye movements, and sometimes mild weakness, especially during or after fever episodes. Lippincott Journals+1

2. Reflex assessment
   Deep tendon reflexes (knee, ankle, elbow) are tested with a reflex hammer. In CAPOS, reflexes are usually reduced or absent in both arms and legs, a key sign called generalized areflexia that helps separate CAPOS from some other ataxia syndromes. Lippincott Journals+1

3. Foot and posture examination
   The clinician inspects the feet while standing and walking. High arches, toe clawing, or other deformities point to pes cavus and long-term imbalance of foot muscles, supporting a diagnosis of CAPOS or related hereditary neuropathies. malacards.org+1

4. Vision and eye examination in clinic
   Basic checks of visual acuity (reading letters) and eye movements can show reduced vision and abnormal eye positioning or tracking. These simple tests suggest optic nerve or cerebellar problems that will then be studied in more detail by an eye specialist. EyeWiki+1

5. Hearing screening in the clinic
   Simple tests, such as speaking softly from behind the child or using a tuning fork, can show reduced hearing and suggest sensorineural hearing loss. These bedside checks guide the need for formal audiology testing. ScienceDirect+1

Manual / bedside tests

6. Finger-to-nose and heel-to-shin tests
   The child is asked to touch their nose with a finger, then touch the doctor’s finger, or to run their heel down the opposite shin. In CAPOS, movements are often shaky, slow, or inaccurate, showing cerebellar ataxia. NCBI+1

7. Romberg test
   The child stands with feet together, first with eyes open, then closed. Swaying or falling more when the eyes are closed suggests problems with balance systems, including the cerebellum and sensory nerves, as in CAPOS. Beyond the Ion Channel+1

8. Tandem gait test (heel-to-toe walking)
   Walking in a straight line placing one foot directly in front of the other is especially difficult for people with cerebellar ataxia. Poor tandem gait supports the presence of a chronic balance disorder. NCBI+1

9. Manual muscle strength testing
   The doctor asks the child to push or pull against resistance with arms and legs. Any weakness, especially around an acute episode, helps show that not only balance but also motor pathways are affected. www.elsevier.com+1

10. Bedside hearing tests (Rinne and Weber)
    With a tuning fork, the examiner compares air and bone conduction and checks how sound is heard on each side. Patterns seen in CAPOS are consistent with sensorineural rather than conductive hearing loss, pointing to inner ear or nerve involvement. ScienceDirect+1

Laboratory and pathological tests

11. Basic blood tests (screening panel)
    Blood counts, electrolytes, liver and kidney function, glucose, thyroid hormones, and vitamin levels are often checked. These tests are usually normal in CAPOS, but they are important to exclude more common metabolic, nutritional, or endocrine causes of ataxia and neuropathy. Beyond the Ion Channel+1

12. Infection and inflammation studies
    During an acute episode, doctors may test blood or cerebrospinal fluid (CSF) to rule out meningitis, encephalitis, or autoimmune diseases. In CAPOS, these tests generally do not show infection or strong inflammation, which helps distinguish CAPOS from these serious conditions. PMC+1

13. Genetic testing for ATP1A3 mutations
    DNA from blood or saliva is analyzed to look for changes in the ATP1A3 gene. Finding the characteristic p.Glu818Lys mutation or another disease-causing ATP1A3 variant confirms the diagnosis of CAPOS or an ATP1A3-related disorder. Europe PMC+2PubMed+2

14. Panel or exome sequencing
    If the diagnosis is unclear, broader gene panels for ataxia or whole-exome sequencing may be ordered. These tests can detect ATP1A3 mutations even when CAPOS was not suspected at first, and can also help rule out other genetic causes of ataxia and neuropathy. Frontiers+1

Electrodiagnostic tests

15. Auditory brainstem response (ABR) testing
    ABR measures how sound signals travel from the ear to the brainstem. In CAPOS, ABR can be abnormal even when outer hair cells are preserved, showing that the hearing loss is mainly neural and supporting the diagnosis of sensorineural hearing loss. ScienceDirect+1

16. Nerve conduction studies (NCS)
    NCS measure how fast and how strongly electrical signals travel in peripheral nerves. In some CAPOS patients, these tests may show mild neuropathy or can be near-normal, but they help rule out other causes of areflexia such as classic peripheral neuropathies. Lippincott Journals+1

17. Electromyography (EMG)
    EMG uses small needles in muscles to measure electrical activity. It can show whether muscle weakness is caused by nerve or muscle problems. In CAPOS, EMG may be used mainly to exclude other conditions, and results can be normal or show mild neuropathic changes. Lippincott Journals+1

18. Electroencephalogram (EEG)
    EEG records brain electrical activity. During acute encephalopathy in CAPOS, EEG may show generalized slowing, which is non-specific but confirms that brain function is altered. EEG also helps rule out seizure disorders if there are episodes of unresponsiveness or abnormal movements. PMC+1

Imaging tests

19. Brain MRI (magnetic resonance imaging)
    MRI is the key imaging test. In many CAPOS patients, MRI can be normal, but some show mild cerebellar or brainstem changes or later cerebellar volume loss. A normal MRI during attacks makes doctors think of genetic causes rather than structural brain injury from stroke or infection. Lippincott Journals+1

20. Optic nerve and inner ear imaging
    MRI or CT may be used to look at the optic nerves, optic pathways, and inner ear structures. These studies can help rule out tumors, inflammation, or malformations, and sometimes show thinning of the optic nerves that fits with optic atrophy in CAPOS. EyeWiki+1

Non-pharmacological treatments

Below are 20 non-drug treatments. All should be planned and supervised by trained therapists and doctors. They do not cure the gene problem, but they help the child function better in daily life. EyeWiki+1

1. Comprehensive rehabilitation program
   A rehabilitation program means a long-term plan that combines physical therapy, occupational therapy, speech therapy, and school support. The purpose is to improve movement, independence, communication, and learning. The team regularly checks the child, adjusts goals, and teaches the family exercises and safety strategies for home. Over time, this coordinated care can reduce disability and improve quality of life. EyeWiki

2. Physical therapy for balance and coordination
   Physical therapy uses simple exercises to improve walking, standing, and balance. The goal is to reduce falls and help the child move more confidently. Therapists may practice wide-based walking, standing with support, and gentle strength training. The mechanism is that repeated, guided movement helps the brain use “neuroplasticity,” where healthy neurons learn to take over some balance functions. EyeWiki+1

3. Gait aids and mobility devices
   Some people with CAPOS need devices such as ankle-foot orthoses, canes, walkers, or wheelchairs for long distances. The purpose is to keep the person safe and reduce fatigue. These devices work mechanically by widening the base of support, stabilizing weak ankles, and reducing the effort needed to move. Early use can prevent injuries from repeated falls. NCBI+1

4. Occupational therapy for daily living skills
   Occupational therapists help with fine motor tasks like writing, feeding, dressing, and using tools or electronic devices. The purpose is to keep the person as independent as possible at home and school. They may suggest special grips, adaptive cutlery, and ways to simplify tasks so that tremor and poor coordination have less impact. EyeWiki

5. Speech and language therapy
   Speech therapy supports both speech clarity and understanding. Some people with CAPOS have slurred speech or trouble coordinating breath and voice. The therapist teaches slower speech, breath control, and sometimes alternative communication methods (like picture boards or tablets) if speech is very hard. This helps the person communicate clearly with family, teachers, and doctors. EyeWiki+1

6. Orthotic management for pes cavus
   High-arched, stiff feet can be painful and unstable. Custom shoe inserts or ankle-foot orthoses spread weight more evenly, support the arch, and keep the ankle from turning in or out. The purpose is to reduce pain and prevent falls. Over time, orthotics can also slow the worsening of foot deformity and delay the need for surgery. NCBI

7. Low-vision rehabilitation
   Optic atrophy often causes blurred or reduced central vision. Low-vision specialists offer magnifiers, strong reading lights, large-print materials, and orientation training. The purpose is to help the person use remaining vision more effectively. The mechanism is not to repair the optic nerve, but to adapt tasks and environments so that limited vision is enough for reading, school work, and daily activities. EyeWiki+1

8. Orientation and mobility training for visual loss
   If vision becomes severely reduced, orientation and mobility training teaches safe movement indoors and outdoors. This may include white cane skills, use of tactile landmarks, and learning safe road crossing. The goal is to maintain independence and safety even with poor vision. Training uses repeated practice so the brain can rely more on touch and hearing. Genome Institute+1

9. Hearing aids
   For mild to moderate sensorineural hearing loss, hearing aids can amplify sound and make speech clearer. In CAPOS, hearing loss may behave like auditory neuropathy, so benefit varies. The mechanism is electronic amplification and sound processing that makes speech easier to detect in quiet settings, improving communication, especially when combined with speech therapy. MDPI+2Frontiers+2

10. Cochlear implantation
    For severe or profound hearing loss, cochlear implants may be considered. These devices bypass damaged hair cells and directly stimulate the hearing nerve with electrical signals. Studies in auditory neuropathy and CAPOS suggest that cochlear implants can give useful hearing and improve speech understanding in many patients. Careful testing is needed to decide if the nerve and brain can use the electrical signal well. journalofhearingscience.com+3PMC+3MDPI+3

11. Auditory-verbal therapy
    After getting hearing aids or a cochlear implant, auditory-verbal therapy helps the brain learn to understand sounds and speech. The therapist trains listening skills, sound identification, and speech production in a structured way. Over time, this can greatly improve spoken language and school performance. MDPI+1

12. Individualized education plan (IEP) and school support
    Many children with CAPOS need classroom adaptations, such as seating near the teacher, captioning, large print, extra time for tasks, and mobility support. An individualized education plan formalizes these supports. The purpose is to give equal access to learning, not to lower standards. This reduces stress and helps the child reach their academic potential. NCBI+1

13. Psychological support and counseling
    Living with a chronic rare disease can cause sadness, frustration, or anxiety in both the child and family. Counseling offers a safe space to discuss fears, coping strategies, and family stress. The mechanism is emotional support, cognitive-behavioral techniques, and psychoeducation about the illness, which can reduce depression and improve resilience. Frontiers+1

14. Genetic counseling for family planning
    CAPOS syndrome is usually autosomal dominant, so a parent with the mutation has a 50% chance of passing it to a child. Genetic counseling explains these risks in simple terms, discusses testing options, and supports informed decisions about future pregnancies. It also helps family members understand why the condition occurred and reduces guilt or blame. NCBI+1

15. Fever prevention and early fever management
    Acute attacks of ataxia and worsening hearing or vision often follow fever or infections. Families are taught to use antipyretics, plenty of fluids, and early medical review when fever starts. The purpose is to shorten the fever and lower stress on the nervous system, which may reduce the severity of attacks. EyeWiki+1

16. Healthy sleep routine and fatigue management
    Poor sleep can worsen balance, concentration, and mood. A regular sleep schedule, quiet bedroom, and avoiding screens before bed improve sleep quality. Planning rest breaks during the day reduces fatigue. The mechanism is to stabilize brain function, reduce stress hormones, and support overall functioning. Frontiers+1

17. Home safety modifications
    Simple changes like grab bars, non-slip mats, good lighting, and removing loose rugs lower the risk of falls. For children, gates on stairs and corner protectors may help. These physical changes work by reducing environmental hazards so that balance problems are less likely to cause serious injury. NCBI+1

18. Balance and core-strength exercise programs
    Gentle exercises such as seated balance drills, core strengthening, and supported standing improve trunk control. The purpose is to stabilize the body so that the arms and legs can function better. Repetition strengthens muscles and improves coordination pathways in the nervous system. Exercises must be adapted to fatigue and safety. Frontiers+1

19. Hydrotherapy (water-based therapy)
    Therapy in a warm pool lets people move with less fear of falling because water supports the body. Therapists can practice walking, stretching, and coordination exercises in water. This can increase confidence and comfort with movement, especially in children who have become fearful of walking after repeated falls. Frontiers

20. Patient and family support groups
    Because CAPOS is rare, families may feel isolated. Online or in-person support groups link them with others facing similar challenges. Sharing experiences, tips, and feelings provides emotional support and practical problem-solving. This social connection can reduce stress and improve adherence to therapies. The JCN+1

Drug treatments

Very important: there is no medicine currently approved specifically to cure CAPOS syndrome. All drug use is symptomatic (for fever, seizures, spasticity, etc.) and must be tailored by a neurologist or pediatrician. Many drugs used in neurology are powerful and can themselves cause ataxia, vision changes, or hearing problems if misused, so no medication should be started, stopped, or changed without medical supervision. NCBI+1

Because CAPOS is so rare, there are not really 20 separate evidence-based drugs proven just for this syndrome. Below are key medicines that may be used for symptoms or to reduce triggers, with examples of FDA prescribing information from accessdata.fda.gov. They are mainly based on general neurologic or hearing-loss practice, not on large CAPOS-specific trials.

1. Paracetamol (acetaminophen) for fever control
   Paracetamol is an over-the-counter medicine used worldwide for fever and mild pain. In CAPOS, it may be used early in a fever illness to keep temperature down and reduce stress on the nervous system, because attacks often follow high fevers. It works in the brain to reduce the “thermostat” set point. Dosage and timing must follow national guidelines and doctor advice, especially in children, to avoid liver damage. EyeWiki+1

2. Ibuprofen (NSAID) for fever and musculoskeletal pain
   Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) used for pain and fever. It may help with aches after falls or long walking, and can also reduce fever. It works by blocking prostaglandin production, which lowers inflammation and pain. FDA labeling warns about stomach, kidney, and heart risks with high doses or long-term use, so doctors choose the lowest effective dose and shortest duration. FDA Access Data+1

3. Topiramate for migraine-like or episodic neurologic attacks
   Topiramate is an anti-seizure drug also used to prevent migraines. EyeWiki notes it as one of the preventive options sometimes considered in ATP1A3-related disorders like CAPOS to reduce attack frequency, although evidence is limited. It affects several brain channels to calm overactive neurons. FDA labeling describes seizure and migraine indications and warns about cognitive slowing, weight loss, and kidney stones, so careful dose titration is needed. EyeWiki+2FDA Access Data+2

4. Acetazolamide for episodic ataxia-like symptoms (off-label)
   Acetazolamide, a carbonic anhydrase inhibitor, is widely used for conditions like glaucoma and some episodic ataxias. It slightly acidifies the blood and brain, which can stabilize firing of some neurons. Some clinicians may cautiously try it in ATP1A3-related episodic symptoms, although there is no strong CAPOS-specific evidence. FDA information for DIAMOX warns about electrolyte imbalance, kidney stones, and rare serious reactions, so monitoring is essential. FDA Access Data+2FDA Access Data+2

5. Baclofen for spasticity or painful muscle stiffness
   If a person with CAPOS develops spasticity, baclofen, a GABA-B agonist, can help relax over-active muscles. It works by slowing down nerve signals in the spinal cord. FDA labels for baclofen products such as OZOBAX and FLEQSUVY show approved uses in spasticity and warn about drowsiness, weakness, and serious withdrawal if suddenly stopped. In CAPOS, doses must be carefully adjusted to avoid worsening balance. FDA Access Data+2FDA Access Data+2

6. Pregabalin or gabapentin for neuropathic pain (if present)
   Some patients with ATP1A3-related disorders may have neuropathic pain or discomfort. Pregabalin and gabapentin calm over-excited pain nerves by affecting calcium channels. FDA labeling for pregabalin (LYRICA) describes its use in neuropathic pain and notes side effects like dizziness and ataxia, so clinicians are cautious in people who already have poor balance. FDA Access Data+1

7. Antiemetic medicines for vertigo-related nausea
   During acute attacks, nausea and vomiting may occur due to severe dizziness and imbalance. Doctors may use anti-nausea drugs such as ondansetron or other agents to keep the patient hydrated and comfortable. These medicines block certain brain receptors involved in vomiting. They are used short-term, with attention to heart rhythm and other safety issues described in their FDA labels. Frontiers

8. Benzodiazepines (for severe vertigo or anxiety – very carefully)
   Short courses of medicines like clonazepam or diazepam may sometimes be used for severe vertigo, muscle jerks, or anxiety during attacks. They work by boosting GABA, the main calming chemical in the brain. However, they can cause drowsiness, dependence, and worse balance, so specialists use the lowest dose for the shortest time and avoid long-term use, especially in children and teens. Frontiers

9. Migraine-type preventive medicines (other than topiramate)
   Because some ATP1A3 disorders have migraine-like components, neurologists may consider other preventive agents such as beta-blockers or calcium-channel blockers if the patient also has migraine. These drugs act on blood vessels and brain excitability. In CAPOS, this is strictly individualized and based on the person’s full medical picture, as there are no CAPOS-specific trials. Frontiers+1

10. Vitamin replacement when there is a proven deficiency
    If blood tests show low vitamin B12, folate, or vitamin D, doctors prescribe standard replacement doses. These are not specific CAPOS drugs, but correcting deficiencies can prevent extra nerve damage and bone weakness. FDA-approved vitamin products have clear dosing recommendations and safety information that must be followed to avoid toxicity, especially with fat-soluble vitamins. Frontiers+1

11. Corticosteroids for other autoimmune problems (not CAPOS itself)
    CAPOS is genetic, not autoimmune, so steroids do not treat the basic disease. However, if a patient also has an autoimmune condition (like optic neuritis unrelated to CAPOS), doctors may use steroids as usual. These drugs reduce inflammation but can cause high blood sugar, infection risk, and bone thinning, so they are reserved for clear indications and short courses. Frontiers+1

12. Standard infection-treatment antibiotics or antivirals
    Because attacks are often triggered by infections and fever, fast and correct treatment of infections with appropriate antibiotics or antivirals is important. These drugs kill or block germs, helping the fever settle. Doctors choose agents based on guidelines and cultures, taking care to avoid medicines known to damage hearing or kidneys whenever possible. Lcehen+1

Beyond these examples, there is no strong evidence for a long list of other drugs specifically for CAPOS. Any extra medicine should only be added by a specialist team after weighing risks and benefits.

(Because you asked for “20 drugs”, but current science does not support 20 clearly useful and distinct medicines just for CAPOS, I have focused on the most realistic, evidence-linked options instead of inventing unproven treatments.)

Dietary molecular supplements

Dietary supplements may support overall nerve and brain health, but they cannot replace medical treatment. They should only be used with a doctor’s approval, especially in children, pregnant women, or people taking many medicines. Evidence in CAPOS itself is very limited, so these suggestions are based on general neurology and nutrition principles. Frontiers+1

1. Vitamin B12
   Vitamin B12 is vital for healthy myelin, the protective coat around nerves. Low B12 can cause neuropathy and balance problems. Supplementation, usually by mouth or injection, is used when blood levels are low. In CAPOS, correcting a deficiency prevents extra damage on top of the genetic problem. Doctors choose the dose and frequency based on lab tests and age.

2. Folate (vitamin B9)
   Folate helps cells divide and repair DNA. Deficiency can cause anemia and neurologic symptoms like numbness and poor concentration. Supplement tablets or diet rich in leafy greens and beans can restore levels. In CAPOS, good folate status supports general nerve function and energy but does not fix the ATP1A3 gene.

3. Vitamin D
   Vitamin D is important for bone strength, muscle function, and immune balance. People with limited mobility may get less sunlight and have low vitamin D. Supplementation, guided by blood testing, helps maintain strong bones and muscles, reducing fracture risk after falls. Over-use can cause high calcium, so doses must follow medical advice.

4. Omega-3 fatty acids (fish oil or algae oil)
   Omega-3 fats (EPA and DHA) are building blocks of brain and nerve cell membranes. They may have anti-inflammatory effects and modest benefits for cardiovascular and brain health. In CAPOS, they are used as general support for brain health and heart protection. Usual side effects are mild stomach upset or fishy taste; high doses may increase bleeding risk.

5. Coenzyme Q10
   Coenzyme Q10 is involved in energy production inside mitochondria. Some neurologists try it in various neurodegenerative disorders to support energy metabolism. In CAPOS there is no direct trial evidence, but it may be considered as an adjunct if the family and doctor agree. Common doses are divided across the day with food; it is usually well tolerated.

6. L-carnitine
   L-carnitine helps move fatty acids into mitochondria for energy. In people with low levels or high energy demand, supplementation may reduce fatigue and muscle pain. In CAPOS, it can be considered if a metabolic doctor identifies an additional fatty-acid oxidation issue or unexplained tiredness. Doses are individualized to avoid stomach upset.

7. Magnesium
   Magnesium is important for nerve and muscle relaxation. Some people with neurologic disorders and cramps benefit from moderate magnesium supplementation. Doctors must check kidney function and drug interactions, because too much magnesium can cause diarrhea or, rarely, heart rhythm problems.

8. Vitamin C
   Vitamin C is an antioxidant that protects cells from oxidative stress and supports collagen and blood vessels. A balanced diet with fruits and vegetables usually gives enough, but supplements can be used if intake is poor. In CAPOS, it is more about general health and immune support than direct nerve repair.

9. Vitamin E
   Vitamin E is another antioxidant, especially important for nerve cell membranes. In certain rare ataxias due to vitamin E deficiency, high-dose replacement improves symptoms. In CAPOS, supplementation should only be considered under specialist guidance, because very high doses may increase bleeding risk and interact with other drugs.

10. Zinc
    Zinc supports immune function and wound healing. Low levels can increase infection risk. A short, supervised course of zinc may be used if deficiency is documented, but long-term high doses can lower copper and cause anemia or nerve problems, so careful monitoring is needed.

Regenerative, immunity booster, and stem-cell-related drugs

Right now, there are no approved stem-cell or gene therapies for CAPOS syndrome. Research in other neurologic diseases gives hope for the future, but treatments are still in laboratories or early trials. Any “stem cell clinic” that promises a cure without strong evidence should be viewed very carefully and discussed with trusted specialists. Frontiers+1

1. Immune-modulating vitamins and lifestyle
   Rather than “immune-booster drugs”, doctors usually focus on good sleep, balanced diet, vaccines, and treatment of vitamin deficiencies to keep the immune system working correctly. Over-stimulation of the immune system can actually cause harm, so simple healthy habits are safer and more evidence-based.

2. Gene therapy concepts for ATP1A3
   Researchers are studying how to correct faulty genes using viral vectors or gene-editing tools. For ATP1A3, this could, in theory, restore more normal pump function in neurons. At present this is experimental and not available as routine care, but families may hear about animal models and early lab work in the coming years.

3. Induced pluripotent stem cells (iPSCs) for disease modeling
   Some labs create iPSC lines from patients with ATP1A3 mutations to study neurons in dishes. These cells help scientists understand how the mutation changes cell behavior and to test candidate drugs safely. This is a research tool, not a treatment, but it is an important step toward future therapies.

4. Neuroprotective growth factor research
   Growth factors like BDNF and other neurotrophins can protect neurons in animal models, but using them safely in humans is challenging. Clinical trials in other diseases are ongoing. None is approved for CAPOS specifically, and risks and benefits need careful study before use.

5. Experimental inner-ear hair cell regeneration
   Several companies and research groups are testing treatments to regenerate or protect inner-ear hair cells, which are important in sensorineural hearing loss. These are in early-phase trials for more common types of deafness. CAPOS patients may someday benefit indirectly if such therapies become safe and widely available, but this is not standard care yet. MDPI+1

6. Neuro-rehabilitation as “functional regeneration”
   The most practical “regenerative” strategy today is intensive neuro-rehabilitation. By repeating tasks and exercises, the brain strengthens remaining pathways and creates new connections. This does not regrow damaged cells, but it can significantly improve function and independence, which is why therapy is so central in CAPOS management. Frontiers+1

Surgeries and procedures

1. Cochlear implant surgery
   When hearing loss in CAPOS is severe and hearing aids give little benefit, cochlear implants may be recommended. Surgeons place an electrode array in the inner ear and connect it to an external sound processor. The main reason is to provide access to speech sounds, improve communication, and support language development. Outcomes in CAPOS and auditory neuropathy can be good when the nerve and brain can use the signal. PMC+2MDPI+2

2. Foot surgery for severe pes cavus
   If high-arched feet become very rigid, painful, or cause frequent falls despite orthotics, orthopedic surgeons may correct the deformity. Procedures might include tendon lengthening, bone reshaping (osteotomy), or fusing certain joints to give a flatter, more stable foot. The purpose is to reduce pain and improve standing and walking, especially in older children or adults. NCBI+1

3. Orthopedic surgery for contractures or scoliosis
   Some individuals with chronic mobility problems develop joint contractures or spinal curvature. Surgery may be needed when these problems cause pain, breathing issues, or prevent the person from sitting or walking comfortably. The main goal is to improve function and ease of care, not to treat the gene problem itself.

4. Gastrostomy tube (feeding tube) placement (rare and only if needed)
   If swallowing becomes unsafe and leads to repeated chest infections or poor nutrition, doctors may suggest placing a feeding tube directly into the stomach. This procedure is done to protect the lungs from aspiration and ensure enough calories and fluids. It is usually considered only after swallow studies and when other methods are not enough.

5. Ophthalmic procedures (for associated eye problems)
   Optic atrophy cannot be reversed by surgery, but people with CAPOS may also develop treatable problems like cataracts or strabismus (eye misalignment). Standard eye surgeries for these conditions can improve remaining vision or eye comfort. The decision depends on detailed eye examination and overall health. EyeWiki+1

Prevention and lifestyle tips

Prevention in CAPOS focuses on reducing attacks, avoiding extra damage, and staying as healthy as possible.

1. Keep all routine vaccinations up to date to lower the chance of serious infections and high fevers. Lcehen

2. Treat fever and infections quickly with medical advice, including fluids, fever medicines, and appropriate antibiotics when needed. Lcehen+1

3. Avoid heavy physical over-exertion during or just after an illness, because this can trigger or worsen attacks. EyeWiki

4. Maintain regular sleep and rest, since tiredness can worsen balance and mood. Frontiers

5. Use hearing protection in extremely loud environments to avoid extra noise damage to already fragile ears. MDPI

6. Protect the eyes with good lighting, sunglasses in bright light, and regular eye checks to detect treatable problems early. EyeWiki

7. Prevent falls with safe home design, proper footwear, and supervised mobility training. NCBI+1

8. Avoid harmful substances such as tobacco, recreational drugs, and (for adults) limit alcohol, because they can worsen nerve and brain health. Frontiers

9. Keep a symptom diary to track triggers, attacks, and responses to treatment; share this with doctors to refine the management plan. EyeWiki

10. Attend regular follow-up visits with neurology, ophthalmology, ENT/audiology, and rehabilitation teams to catch problems early and adjust therapies. NCBI+1

When to see doctors

People with CAPOS syndrome should have regular scheduled visits, but there are also warning signs that need urgent or same-week review.

You should see or contact a doctor urgently (emergency service if severe) if:

• There is a new or sudden worsening of balance, with many falls or inability to stand or walk that is much worse than usual, especially with fever. EyeWiki+1

• Vision suddenly becomes much more blurred, double, or there is new loss of part of the visual field. EyeWiki+1

• Hearing suddenly drops, or there is new loud ringing in the ears, especially after a new medicine or illness. Frontiers+1

• There is any sign of seizure, loss of consciousness, severe headache, or confusion. Frontiers+1

• Feeding becomes unsafe, with frequent choking, coughing during meals, or weight loss.

• There are repeated chest infections, very fast breathing, or blue lips.

• Mood changes become severe, with withdrawal, persistent sadness, or strong anxiety that interferes with daily life.

You should also see your specialists in the next few weeks if you notice gradual changes in walking, school performance, behavior, or if you are thinking about major decisions like surgery, cochlear implantation, or pregnancy planning.

Because you are a teen, it is especially important to tell a trusted adult and a doctor about any worrying symptoms; do not try to handle serious problems alone.

What to eat and what to avoid

Diet in CAPOS focuses on general brain and body health, bone strength, and infection resistance. There is no “magic diet” that cures the gene change.

1. Eat plenty of fruits and vegetables
   Colorful fruits and vegetables provide vitamins, minerals, and antioxidants that support the immune system and overall health. Aim for several servings per day, in easy-to-chew forms if coordination is difficult.

2. Choose whole grains instead of refined grains
   Whole grains like oats, brown rice, and whole-wheat bread give steady energy and fiber, which helps gut health and prevents constipation, especially in less-mobile people.

3. Include lean protein in every meal
   Fish, eggs, beans, lentils, poultry, and dairy provide protein for muscle maintenance and repair. This is important when muscle use is reduced by movement problems.

4. Ensure enough calcium and vitamin D
   Milk, yogurt, fortified plant milks, cheese, and leafy greens help keep bones strong. Strong bones reduce fracture risk when falls occur. Doctors may add vitamin D supplements based on blood tests.

5. Use healthy fats
   Olive oil, nuts, seeds, and fatty fish give unsaturated fats and omega-3s that support heart and brain health.

6. Limit very salty and heavily processed foods
   Too much salt, fast food, and packaged snacks can raise blood pressure and cause weight gain, which makes moving harder and increases heart risk.

7. Avoid sugary drinks and excessive sweets
   Sugary drinks give quick calories without nutrients and can lead to weight gain and dental problems. Water is the best drink most of the time.

8. Avoid alcohol (especially underage)
   Alcohol can damage brain cells, worsen balance, interact with medicines, and is illegal for minors in most countries. Adults with CAPOS should discuss any alcohol use with their doctor; teens should avoid it completely.

9. Be careful with “miracle” supplements or restrictive fad diets
   Very strict diets or untested “miracle cures” found online can cause malnutrition and interact with medicines. Always check with a doctor or dietitian before starting any new supplement or diet plan.

10. Work with a dietitian if chewing or swallowing is difficult
    A dietitian can suggest texture-modified foods, calorie-dense smoothies, or thickened fluids to maintain good nutrition while keeping swallowing safe. Frontiers+1

Frequently asked questions

1. Is CAPOS syndrome curable?
   No, CAPOS syndrome is a lifelong genetic condition caused by changes in the ATP1A3 gene. Current treatments cannot remove or replace this gene, so the focus is on reducing attacks, supporting movement, vision, and hearing, and improving quality of life with therapy and assistive devices. NCBI+1

2. Will symptoms always get worse?
   Many people have acute worsening during fever illnesses and then some partial recovery, but often a stepwise long-term decline in hearing, balance, or vision. The speed and pattern vary widely. Good rehabilitation, careful fever management, and regular follow-up may slow functional decline and help the person adapt better. EyeWiki+1

3. Is CAPOS syndrome always inherited from a parent?
   CAPOS is usually autosomal dominant, but sometimes the mutation happens for the first time in the child (a “de novo” mutation). Gene testing and genetic counseling are needed to understand the pattern in each family. NCBI+2The JCN+2

4. What is the life expectancy in CAPOS?
   Because CAPOS is very rare, long-term data are limited, but most reported patients live into adulthood. Quality of life depends more on the severity of hearing, vision, and mobility problems and on how well complications such as falls and infections are prevented and treated. NCBI+1

5. Can cochlear implants really help hearing in CAPOS?
   Yes, several case reports and studies in auditory neuropathy and CAPOS describe meaningful improvements in hearing and speech understanding after cochlear implantation, although results vary between individuals. Careful testing by an experienced cochlear implant team is needed to see if the auditory nerve can respond to stimulation. PMC+2journalofhearingscience.com+2

6. Can vision be restored in optic atrophy?
   Unfortunately, optic atrophy means the optic nerve fibers are damaged or lost, and current medicine cannot regrow them. However, low-vision aids, good lighting, and treatment of other eye problems like cataracts can make the best use of remaining vision. EyeWiki+1

7. Does every fever cause permanent worsening?
   Not every fever leads to permanent change, but many reports describe attacks triggered by febrile illnesses. Some people return near their previous level after an attack, while others are left with new deficits. That is why infection prevention, early fever treatment, and medical review are so important in CAPOS families. Lcehen+1

8. Are vaccines safe in CAPOS syndrome?
   Yes. In general, vaccines prevent serious infections and high fevers, which are known triggers of attacks. For most people with CAPOS, staying up to date with routine vaccines is strongly recommended, but any special concerns should be discussed with the neurologist and pediatrician. Lcehen+1

9. Can a child with CAPOS attend regular school?
   Many children with CAPOS attend mainstream school with supports such as hearing technology, large-print materials, and physical access adaptations. The right setting depends on the child’s hearing, vision, and learning profile. An individualized education plan helps match support to needs. NCBI+1

10. Will my child eventually need a wheelchair?
    Some people with CAPOS continue to walk with aids, while others use wheelchairs for longer distances or full-time. Wheelchairs are not a failure, but a tool to increase independence, safety, and participation. Decisions are made with the rehabilitation team and the family, based on fatigue, falls, and comfort. NCBI+1

11. Is it safe to play sports?
    Gentle, well-supervised activities like swimming (with proper safety), adapted physical education, or supported cycling can be healthy and enjoyable. Contact sports or activities with high fall risk may be unsafe. A physical therapist or sports doctor can help choose suitable activities. Frontiers+1

12. Are there clinical trials for CAPOS or ATP1A3 disorders?
    Clinical trials for ATP1A3-related conditions are limited but may appear as research grows. Families can ask their neurologist about registries or research studies and may search trustworthy trial registries with professional guidance. Participation is always voluntary and must follow strict safety rules. Frontiers+1

13. Can diet alone treat CAPOS?
    No. A healthy diet supports general health and may prevent extra problems like weak bones or obesity, but it cannot correct the underlying gene defect. Any major diet changes or supplements should be seen as supportive and always discussed with the care team. Frontiers+1

14. Is CAPOS the same as other ATP1A3 disorders like AHC or RDP?
    CAPOS, alternating hemiplegia of childhood (AHC) and rapid-onset dystonia-parkinsonism (RDP) are all caused by mutations in ATP1A3, but they have different symptom patterns. CAPOS is unique because it combines cerebellar ataxia, areflexia, pes cavus, optic atrophy, and sensorineural hearing loss. Frontiers+2NCBI+2

15. What is the most important thing families can do?
    The most important steps are: building a strong partnership with a knowledgeable medical and rehabilitation team, preventing and treating fevers quickly, supporting communication and learning, and caring for emotional health of the child and family. These actions cannot cure CAPOS, but they can make a big difference in daily life and long-term outcomes. EyeWiki+2Frontiers+2
