Aicardi syndrome is a rare brain and eye development disorder that almost always affects baby girls. Doctors first look for a “classic triad”: 1) the corpus callosum is partly or completely missing (this is the bridge that connects the two halves of the brain), 2) special white patches in the back of the eye called chorioretinal lacunae, and 3) seizures that start in infancy, usually infantile spasms. Most cases happen by chance (not inherited). The exact gene is still unknown, but the pattern strongly suggests a change on the X chromosome, which is why it is seen almost only in females and very rarely in boys with an extra X chromosome (XXY). The diagnosis is clinical and based on exams, brain imaging, and eye findings. NCBI+1MedlinePlusAAO
Aicardi syndrome (AS) is a rare disorder that mostly affects girls. It starts before birth. The brain does not develop in the usual way, especially the corpus callosum (the bundle of nerve fibers that connects the left and right brain). In many children, the corpus callosum is missing or partly formed. Babies often develop infantile spasms (a seizure type). The eyes can have special scars called chorioretinal lacunae. Some children also have small head size, spine curves (scoliosis), feeding problems, low or high muscle tone, and delays in movement, speech, and learning. The condition happens de novo (by chance) and is thought to be X-linked dominant, which is why it mainly appears in girls and very rarely in boys. There is no single cure today. Care focuses on controlling seizures, supporting movement and feeding, protecting vision, building communication, preventing complications, and helping the child and family live the best possible daily life.
Another names
Aicardi syndrome is also called: Aicardi’s syndrome; “agenesis of the corpus callosum with chorioretinal abnormality;” “agenesis of the corpus callosum with infantile spasms and ocular anomalies;” and “callosal agenesis with chorioretinal lacunae.” All these names point to the key features: missing or under-formed corpus callosum, eye changes in the retina, and seizures beginning in infancy. In older texts you may see similar descriptions using these phrases instead of “Aicardi syndrome.” National Organization for Rare Disorders
Types
1) Classic Aicardi syndrome. All three major features are present: corpus callosum agenesis/dysgenesis, chorioretinal lacunae, and infantile spasms. This is the most typical picture. NCBI
2) Probable/atypical Aicardi syndrome. Modified criteria allow diagnosis when two of the three major features are present plus at least two supportive features (such as brain cysts, cortical malformations like polymicrogyria, or characteristic EEG changes). This recognizes that some babies do not show the full triad at first. NCBI
3) Aicardi-like cases in males with extra X chromosome (47,XXY) or mosaicism. Very rare boys can be affected when they have an extra X chromosome or mosaic patterns. MedlinePlus
4) Severity-based description. Doctors often describe cases as mild, moderate, or severe based on seizure burden, brain malformations, and vision level. This is a practical way to plan care even though the underlying gene is unknown. NCBI
Causes
Because the exact gene has not yet been identified, it is more accurate to speak about what we know and what is suspected rather than a single “cause.” Below are the established points and plausible mechanisms reported in the medical literature. I note evidence levels where helpful.
Primary cause: a new (de novo) change on the X chromosome. Nearly all cases occur for the first time in the family, suggesting a spontaneous X-linked mutation. (Strong evidence.) MedlinePlusNCBI
X-linked dominant pattern with male lethality. The condition occurs almost exclusively in girls; rare boys are affected only if they have an extra X (XXY). (Strong evidence.) MedlinePlus
Unknown specific gene (genetic heterogeneity). Many studies show no single shared gene yet; the disorder appears genetically heterogeneous. (Strong evidence.) PMCAmerican Academy of Neurology
Skewed X-inactivation and mosaicism (suspected modifier). Differences in which X chromosome is “turned off” in cells may influence severity. (Moderate/biological plausibility.) NCBI
Copy-number changes on Xp22 in isolated reports. Some cases show duplications involving Xp22; their role is still uncertain. (Limited evidence; case reports.) ResearchGate
Rare autosomal chromosomal imbalances (Aicardi-like phenotypes). Imbalances at 6q/12q have been described in girls with Aicardi-like features; not proven as the core cause. (Limited evidence.) PMC
Early disruption of midline brain development. The missing corpus callosum points to a disturbance of midline patterning in early pregnancy. (Inferred from anatomy and timing.) NCBI
Abnormal cortical development (neuronal migration). Findings like polymicrogyria and heterotopias suggest the mutation affects how neurons move and fold the cortex. (Inferred.) Lippincott Journals
Eye development pathway disruption. Chorioretinal lacunae and optic nerve anomalies indicate interrupted retina/optic nerve formation. (Inferred from pathognomonic eye signs.) PMC
Sporadic occurrence (non-familial). The condition almost never runs in families, supporting de novo changes. (Strong evidence.) MedlinePlus
Not caused by infection. The eye and brain findings can resemble congenital infections, but Aicardi syndrome is not an infection; tests are used to rule infections out. (Clinical distinction.) NCBI
Not linked to pregnancy exposures in a consistent way. No reliable environmental trigger has been shown. (Consensus/negative evidence.) NCBI
Potential modifier: degree of callosal absence. More extensive agenesis often correlates with more severe symptoms, reflecting developmental impact. (Clinical correlation.) NCBI
Potential modifier: presence of cortical malformations. Added malformations (polymicrogyria, cysts) may worsen seizures and development. (Clinical correlation.) Lippincott Journals
Potential modifier: ocular lesion location. Lacunae near the macula or optic nerve can reduce central vision more severely. (Ophthalmic correlation.) PMC
Potential modifier: early seizure control. Heavy seizure burden early in life can worsen outcomes; this is a consequence of the brain malformation rather than a root cause. (Clinical correlation.) BioMed Central
Genetic heterogeneity means multiple rare gene mechanisms may exist. Different girls may have different underlying rare gene errors that converge on the same developmental pathways. (Systematic-review view.) American Academy of Neurology
Germline mosaicism in a parent is possible but rare. This could explain extremely uncommon recurrences. (General genetic principle for de novo disorders.) NCBI
X-chromosome dosage effects. The presence of a second X in girls (and XXY in rare boys) likely permits survival; the same change in a single X may be lethal before birth in typical XY males. (Model consistent with observations.) MedlinePlus
Overall: cause remains “unknown gene(s) on X,” with active research trying to pinpoint it. (Current consensus.) PMCAmerican Academy of Neurology
Symptoms
1) Infantile spasms. Sudden bending of the neck and body with brief arm or leg jerks. These start in the first months of life and often come in clusters. They are a key early sign. NCBI
2) Other seizure types. As the child grows, spasms can change into many seizure types. Seizures can be hard to control. NCBI
3) Developmental delay. Sitting, standing, speaking, and learning may come late or remain limited. Severity varies widely. NCBI
4) Intellectual disability. Most children have moderate to severe learning challenges, though a few have milder disability. PubMed
5) Vision problems. The eye spots (lacunae) and other eye changes can reduce sight; some children have severe low vision. MedlinePlusPMC
6) Nystagmus. Fast, to-and-fro eye movements can appear because of the eye and brain differences. MedlinePlus
7) Optic nerve or eye size differences. The optic nerve may have a gap (coloboma); eyes may be smaller than usual (microphthalmia). MedlinePlus
8) Low muscle tone (hypotonia). Babies may feel “floppy,” with weak head control. Later, tone can become mixed with stiffness. NCBI
9) Abnormal head size. Some children have small head size (microcephaly). Wikipedia
10) Feeding and reflux problems. Swallowing can be slow, and reflux is common. Wikipedia
11) Sleep disturbance. Seizures and neurological differences often disturb sleep cycles. (Clinical observation frequently reported.) NCBI
12) Brain cysts and cortical malformations. Extra fluid spaces and abnormal brain folding commonly coexist and add to symptoms. Lippincott Journals
13) Skeletal differences. Extra or missing ribs and spinal curvatures (scoliosis) can occur. Wikipedia
14) Early or delayed puberty (less common). Some reports describe timing differences in puberty. Wikipedia
15) Overall variability. No two children are the same; the mix of seizures, vision, and development varies across the spectrum. Lippincott Journals
Diagnostic tests
Physical exam (done in the clinic by observation and hands-on exam)
1) General newborn/infant exam with growth measures. The doctor checks weight, length, and head size. A small head size may be seen, but growth can vary. This helps set a baseline and track change over time. NCBI
2) Neurodevelopmental assessment. The team looks at social interaction, motor skills, speech/language, and play to spot delays and plan early therapies. This is repeated regularly because needs change. NCBI
3) Neurological exam (tone, reflexes, movements). The clinician checks tone (floppy or stiff), primitive reflexes, and coordination. Findings guide seizure care and physical/occupational therapy planning. NCBI
4) Dysmorphology and musculoskeletal exam. The spine and rib cage are examined for extra or missing ribs and scoliosis; hips and joints are checked. This can prompt imaging and bracing or surgical referrals. Wikipedia
Manual (bedside/clinical) tests (low-tech, performed directly by the clinician)
5) Dilated fundus examination (ophthalmoscopy). An eye specialist puts in drops to widen the pupil and looks at the retina. Chorioretinal lacunae are often pathognomonic (very specific) for Aicardi syndrome. AAO
6) Visual fixation and tracking assessment. The examiner checks whether the baby looks at faces/lights and follows a moving target. This screens functional vision and helps tailor visual supports. PMC
7) Seizure semiology documentation and home video review. Parents are taught to record spells safely. Careful description of clusters and triggers helps guide EEG timing and treatment choices. BioMed Central
8) Primitive/postural reflex testing (clinical scales). Structured infant neuro exams (e.g., HINE) check head control, rolling, and protective reactions to guide early therapy goals. NCBI
Laboratory and pathological testing (primarily to support and to rule out mimics)
9) Chromosomal microarray (CMA). This test looks for small missing or extra pieces of DNA. It can detect copy-number changes, including rare X-chromosome alterations reported in some cases, and helps exclude other syndromes. ResearchGate
10) Karyotype (sex chromosome analysis). This checks the number and structure of chromosomes and can identify 47,XXY in the rare affected boy. MedlinePlus
11) Clinical exome or genome sequencing. Although no single causal gene is confirmed for all patients, sequencing can find candidate variants and rule out other genetic epileptic encephalopathies. PMC
12) Basic metabolic screening (blood/urine). These tests are usually normal in Aicardi syndrome but help rule out metabolic diseases that can also cause early seizures. (Used as a safety net.) NCBI
13) Infection work-up (TORCH/CMV toxoplasma testing when indicated). Because eye/brain findings can resemble congenital infections, doctors often test to exclude them, confirming the diagnosis points toward Aicardi syndrome. NCBI
Note: There is no blood test that “proves” Aicardi syndrome; diagnosis relies on clinical features, EEG, and imaging, with genetics mainly used to support and to exclude look-alike conditions. Orpha
Electrodiagnostic testing
14) Electroencephalogram (EEG). In early months, the EEG may show infantile spasm patterns; a burst-suppression pattern with asynchrony between hemispheres is highly suggestive in the right clinical context. EEG patterns can evolve over time. Medscape+1
15) Visual evoked potentials (VEP). This measures the brain’s response to visual signals and helps assess visual pathway function when a child is too young to cooperate with standard vision tests. (Supportive test.) PMC
16) Electroretinography (ERG). ERG tests retinal function; it can complement the eye exam by showing how the light-sensing cells work around the lacunae. (Supportive.) PMC
Imaging tests
17) Brain MRI. MRI shows whether the corpus callosum is partly or completely absent and looks for other brain malformations (polymicrogyria, cysts). MRI is central to diagnosis and care planning. AAO
18) Prenatal or postnatal cranial ultrasound. During pregnancy or soon after birth, ultrasound may suggest callosal agenesis or cysts and trigger further evaluation. It is a screening tool, not definitive. AAO
19) CT brain (when MRI is unavailable/urgent). CT can show major structural differences or calcifications but gives less detail than MRI and involves radiation; it is not the first choice when MRI is accessible. (Clinical practice point.) NCBI
20) Ocular imaging (fundus photography and OCT). Photos document the number, size, and location of lacunae over time; optical coherence tomography (OCT) shows the retinal layers and helps explain vision potential.

Dietary molecular supplements
(Evidence base varies; use only with the child’s medical team, especially with antiseizure drugs.)
Omega-3 (DHA/EPA) — Dose: often 20–40 mg/kg/day DHA+EPA combined (example range; clinician-guided). Function/Mechanism: anti-inflammatory membrane effects; may aid cognition and visual pathways. Notes: watch for fish/soy allergies and anticoagulants.
Medium-chain triglyceride (MCT) oil — Dose: titrated by dietitian (e.g., 5–20 mL with meals) or as part of MCT-ketogenic plan. Function: supports ketosis with lower total fat burden. Mechanism: MCTs rapidly convert to ketones. Notes: GI upset if advanced too fast.
L-Carnitine — Dose: clinician-set mg/kg/day; sometimes used with valproate or ketogenic diets. Function: fatty-acid transport into mitochondria. Mechanism: supports beta-oxidation; may reduce valproate-related carnitine depletion. Notes: monitor for fishy odor, GI upset.
Coenzyme Q10 (Ubiquinone/Ubiquinol) — Dose: 2–5 mg/kg/day (example); Function: mitochondrial electron transport. Mechanism: improves cellular energy where mitochondrial stress is suspected. Notes: interactions are rare; take with fat.
Vitamin D3 — Dose: age/level-based; correct deficiency. Function: bone and immune health; may support muscle tone and mood. Mechanism: nuclear receptor signaling. Notes: monitor levels, especially with anticonvulsants that affect bone health.
Magnesium — Dose: dietitian-guided; avoid excess. Function: NMDA receptor modulation; muscle/nerve function. Mechanism: may help sleep and spasm threshold. Notes: diarrhea if too high; check renal function.
Vitamin B6 (maintenance, if needed) — Dose: only if deficiency or per neurology plan after a supervised trial. Function: GABA synthesis cofactor. Mechanism: supports inhibitory signaling. Notes: avoid chronic high doses without monitoring.
Probiotics — Dose: product-specific CFU; clinician-approved. Function: gut microbiome support, may reduce antibiotic-related diarrhea and reflux symptoms. Mechanism: barrier and immune modulation. Notes: caution in immunocompromised states.
Zinc — Dose: correct deficiency only. Function: synaptic function and immunity. Mechanism: cofactor in many enzymes. Notes: excess can lower copper; check levels.
Folate/folinic acid — Dose: clinician-guided, particularly if on antiepileptics affecting folate. Function: one-carbon metabolism for growth and neural function. Mechanism: supports DNA/RNA synthesis and repair. Notes: coordinate with neurology to avoid interactions.
Immunity booster / regenerative / stem-cell drugs
Today there are no approved immune-booster drugs, regenerative drugs, or stem-cell drugs proven to treat or modify the course of Aicardi syndrome. Because AS is genetically complex and often de novo, unregulated “stem-cell” treatments marketed online can be expensive, ineffective, and risky (infection, immune reactions, tumors).
What you can do instead (evidence-concordant alternatives):
Routine vaccinations per national schedule (protects from seizures triggered by fever/infection).
Nutrition optimization with dietitian, including vitamin D and bone health.
Physical and educational therapies (the strongest real-world functional gains come from these).
Clinical trials: ask your neurologist about legitimate registries or trials (if any) at academic centers.
Sleep and infection control plans to reduce seizure triggers.
Targeted spasticity care (e.g., Botox or ITB) to prevent secondary damage.
(Because these “drugs” do not exist for AS, providing dosages would be misleading. If you find a study, bring it to your child’s neurologist to review safety and eligibility.)
Surgeries and procedures
Vagus nerve stimulator (VNS) implantation
Procedure: A small chest device with a lead to the left vagus nerve; programmed to give periodic pulses.
Why done: For refractory epilepsy not fully controlled by medicines/diet. It may reduce seizure frequency/severity over months.
Focal cortical resection or hemispherotomy (select cases)
Procedure: Neurosurgical removal or disconnection of a seizure focus/hemisphere if clear localization exists.
Why done: To control disabling, medically refractory focal seizures. Careful presurgical evaluation is essential.
Gastrostomy tube (G-tube) placement
Procedure: Feeding tube placed through the abdomen into the stomach.
Why done: Poor oral intake, unsafe swallow, or to deliver ketogenic feeds reliably.
Ventriculoperitoneal (VP) shunt
Procedure: Shunt drains extra cerebrospinal fluid from the brain to the abdomen.
Why done: Treat hydrocephalus or pressure symptoms if present.
Spinal fusion (scoliosis surgery) / hip reconstruction (as indicated)
Procedure: Orthopedic surgery to correct severe spine curve or hip displacement.
Why done: Improve sitting balance, reduce pain, and protect skin and organ function.
Prevention and complication-reduction tips
Antenatal and genetic counseling for families planning future pregnancies.
Vaccinations on time; prompt fever management.
Seizure plan at home and school with rescue meds and device monitoring.
Sleep hygiene routines and screen for sleep apnea.
Nutrition with swallow safety and growth monitoring.
Bone health (vitamin D, weight-bearing, DEXA as advised).
Hip/spine surveillance and early therapy/orthopedics.
Infection control: hand hygiene, dental care, reflux control to limit aspiration.
Equipment maintenance: wheelchairs, braces, and feeding pumps checked regularly.
Caregiver training and respite to sustain the care plan.
When to see doctors urgently
New or more frequent seizures, seizure >5 minutes, or repeated clusters.
Fever with vomiting, stiff neck, severe headache, or marked sleepiness.
Breathing problems, bluish lips, choking, or suspected aspiration.
Poor feeding, weight loss, dehydration, or frequent coughing during meals.
Rapid spine curve, new limb weakness, or painful joints.
Eye changes (sudden crossing, loss of tracking), or any regression in skills.
Device issues (VNS, shunt, G-tube) such as redness, swelling, or malfunction.
Diet: what to eat and what to avoid
Consider ketogenic or modified Atkins diet only under neurology/dietitian supervision.
Adequate protein for growth (eggs, dairy/yogurt if tolerated, legumes, fish/poultry as diet allows).
Hydration to reduce constipation and kidney stone risk (especially with topiramate).
Fiber (vegetables, low-glycemic fruits appropriate to diet plan) for gut motility.
Healthy fats (olive oil, avocado, MCT as prescribed) to support energy or ketosis plan.
Texture-modified foods if swallow is unsafe; follow SLP guidance.
Avoid choking hazards (nuts, hard candy) unless safely prepared.
Limit highly processed sugars and excessive salt; they can worsen reflux and sleep.
Watch for interactions (grapefruit with some meds; CBD with valproate—LFTs).
Micronutrient checks (vitamin D, iron, folate) and supplement under medical guidance.
