Auditory Neuropathy

Auditory neuropathy is a hearing disorder where the inner ear (the cochlea) often “hears” sound normally, but the message does not travel correctly along the hearing nerve to the brain. People may detect sounds, but speech can sound unclear or jumbled—especially in background noise—because the timing and coordination (synchrony) of the nerve signals are disturbed. In tests, many people with this condition have normal otoacoustic emissions (OAEs)—which means outer hair cells can work—yet have an absent or very abnormal auditory brainstem response (ABR)—which means the nerve signal timing is faulty. This mismatch is the key pattern that defines ANSD. NIDCD+1

Auditory neuropathy is a hearing problem where the inner ear (especially the outer hair cells) can pick up sound, but the signal gets scrambled or blocked as it travels from the ear to the brain. People may hear sounds, yet spoken words can be unclear or distorted—especially in noisy places. The classic test pattern is normal otoacoustic emissions (OAE) (showing outer hair cells work) together with absent or very abnormal auditory brainstem responses (ABR) (showing a problem in the nerve or neural timing). This pattern happens in babies, children, and adults. Causes range from genetic changes to problems around birth, certain illnesses, or nerve disorders. Management focuses on early detection, communication support, hearing technology trials, and, for many, cochlear implantation when candidacy is met. NIDCD+2PMC+2

In ANSD, outer hair cells may function, but inner hair cells, the synapse (IHC-auditory nerve junction), or the auditory nerve itself does not pass sound information with normal timing. That is why OAEs can be present while ABR is absent/abnormal. This “neural desynchrony” makes speech understanding unusually poor compared with the audiogram. The exact site of lesion varies by person (e.g., OTOF/IHC synaptopathy vs. neuropathy of the nerve). This variability also explains why outcomes with hearing aids vs. cochlear implants differ and why careful evaluation is needed. PMC+1

Other names

• Auditory Neuropathy Spectrum Disorder (ANSD)

• Auditory dys-synchrony / neuropathy–dys-synchrony

• Cochlear synaptopathy (when the problem is at the inner hair cell–nerve synapse)
  All of these point to the same core idea: sound is detected, but neural timing is disrupted along the inner hair cell–synapse–auditory nerve pathway. PMC

In ANSD, the concern is not outer hair cell amplification (often OK), but the conversion of sound into well-timed nerve spikes and their delivery to the brain. The weak link can be: (1) inner hair cells; (2) the synapse between inner hair cells and the auditory nerve (e.g., OTOF/otoferlin defects); or (3) the auditory nerve itself (e.g., neuropathies, nerve deficiency). When the timing is off, the brain cannot build a clear speech signal from the incoming sounds, so understanding words—especially in noise—suffers out of proportion to the “loudness” measured on a basic hearing test. PMC+1

Types

1. By site of problem

• Presynaptic/Inner hair cell–synapse (“synaptopathy”): e.g., OTOF-related ANSD; OAEs present; ABR absent/abnormal. These cases often do well with cochlear implants because the nerve is intact. NCBI+1

• Postsynaptic/Auditory nerve (“neuropathy”): the nerve itself is affected (e.g., hereditary neuropathies, nerve hypoplasia); CI outcomes are more variable. PMC

2. By onset

• Congenital/infant (e.g., genetic causes, prematurity, hyperbilirubinemia). The BSA+1

• Acquired/later (e.g., ototoxic drugs, diabetes, demyelinating disease, tumors). PMC

3. By stability

• Stable vs fluctuating (some OTOF variants are temperature-sensitive, with worse hearing during fever). Frontiers

4. By sidedness

• Bilateral (most) vs unilateral (less common, may relate to nerve anomalies/tumors). PMC

Causes

1. Genetic changes in the OTOF gene (otoferlin)
   OTOF helps inner hair cells release neurotransmitter to the nerve. Faults block precise signaling, so OAEs can be normal but ABR is absent/abnormal—classic ANSD. Some families show temperature-sensitive hearing (worse during fever). NCBI+1

2. Other ANSD-linked genes (PJVK/DFNB59, AIFM1, LOXHD1, and others)
   These genes affect synapses or the auditory nerve. Changes can cause dyssynchrony of nerve firing and poor speech understanding. AIFM1 variants may also bring broader neuropathy. PMC+1

3. Prematurity and neonatal intensive care risk factors
   Very premature infants have delicate inner ear/nerve structures and higher risk from low oxygen, infections, or medications that disturb auditory timing. PMC

4. Severe neonatal hyperbilirubinemia (jaundice)
   High bilirubin can injure auditory brainstem pathways and produce the OAE-present/ABR-abnormal pattern. Effects can be reversible or permanent. PMC+2PMC+2

5. Perinatal hypoxia/asphyxia
   Low oxygen around birth can injure inner hair cell–nerve synapses or the auditory nerve, leading to ANSD. PMC

6. Congenital cytomegalovirus (CMV) infection
   CMV damages inner ear and neural pathways; some babies present with ANSD features on newborn screening. PMC

7. Aminoglycoside antibiotics (ototoxicity)
   These can harm inner ear/inner hair cells; in some, timing pathways are affected disproportionately, producing an ANSD picture. PMC

8. Platinum chemotherapy (e.g., cisplatin)
   May disrupt synapses and cochlear neurons; when neural timing suffers more than sensitivity, ANSD features appear. PMC

9. Auditory nerve hypoplasia/aplasia (nerve underdeveloped or absent)
   MRI may show a small or missing cochlear nerve; OAEs can be present, but neural conduction is limited. PMC

10. Vestibular schwannoma (acoustic neuroma) or other cerebellopontine angle tumors
    A tumor compressing the auditory nerve can cause poor timing (abnormal ABR) with variable OAEs. PMC

11. Hereditary neuropathies (e.g., Charcot–Marie–Tooth)
    Generalized nerve disease can include the auditory nerve and create dys-synchronous hearing. PMC

12. Mitochondrial disorders
    Mitochondrial energy problems can impair the high-speed, energy-hungry auditory synapse/nerve firing required for speech clarity. PMC

13. Diabetes mellitus (metabolic neuropathy)
    Chronic high glucose can damage small nerves, including the auditory nerve, reducing timing precision. PMC

14. Multiple sclerosis and other demyelinating diseases
    Loss of myelin slows and desynchronizes neural conduction in brainstem pathways, often producing abnormal ABR. PMC

15. Autoimmune inner ear disease
    Immune attack on inner ear–nerve interfaces can disturb timing even if some cochlear function remains. PMC

16. Bacterial or viral meningitis
    Inflammation may injure the cochlea and auditory nerve; some survivors show ANSD-like test patterns. PMC

17. Head trauma
    Shearing injury to synapses or the auditory nerve can leave OAEs intact but ABR abnormal. PMC

18. Noise trauma (rarely ANSD-pattern in humans)
    Severe noise can selectively affect synapses (synaptopathy) with disproportionate speech-in-noise trouble even if basic thresholds look better than expected. PMC

19. Hypothyroidism or other endocrine disorders
    Hormonal/metabolic imbalance can worsen neural timing or blood supply to inner ear–nerve structures. PMC

20. Unknown (idiopathic)
    In many patients, no single cause is found despite careful imaging and genetic testing; the test pattern still guides diagnosis and care. PMC

Diagnostic tests

(Grouped by category; clinicians usually use a test battery to confirm ANSD.)

A) Physical exam (otology & neurology)

1. Otoscopy (ear exam)
   Checks ear canal and eardrum. Usually normal in ANSD, which helps rule out conductive problems like wax or infection. The BSA

2. Tympanometry (middle-ear pressure/movement)
   Commonly normal in ANSD, confirming the middle ear system is not the main issue. PMC

3. Acoustic (stapedial) reflex testing
   Often absent or abnormal in ANSD because neural pathways from the ear to the brainstem and back to the middle ear muscle are disrupted. PMC

4. Basic neurologic screen
   Looks for signs of broader neuropathy (weak reflexes, imbalance) that might point to a systemic cause of auditory nerve dysfunction. PMC

5. Developmental/communication milestones review (infants/children)
   Speech-language delays with normal OAEs can raise suspicion for ANSD after newborn screening. Health & Human Services

B) Manual/behavioral audiology

6. Pure-tone audiometry (or VRA/CPA in children)
   Hearing thresholds can range from normal to profound. The key red flag is that thresholds don’t explain the severity of speech understanding problems. Rare Diseases

7. Speech audiometry (quiet)
   Word recognition can be poorer than expected for the pure-tone thresholds because timing, not just loudness, is affected. Rare Diseases

8. Speech-in-noise testing
   Typically very poor because ANSD disrupts the precise timing cues needed to separate speech from noise. Rare Diseases

9. Temporal processing tasks (e.g., gap-detection, amplitude-modulation detection)
   Highlight abnormal neural timing (larger gaps needed, poorer modulation detection). These support the diagnosis when available. Hear Indiana

10. Functional listening assessments (teacher/parent questionnaires)
    Document real-world impact and guide accommodations in school or work. babyhearing.org

C) Laboratory / pathological & etiologic work-up

11. Serum bilirubin (neonates)
    Confirms severe jaundice as a potential cause; ABR often abnormal during/after high bilirubin exposure. PMC+1

12. Congenital CMV testing (saliva/urine PCR in early life)
    Detects CMV, an important, treatable cause of infant hearing problems including ANSD patterns. PMC

13. Genetic testing panel for hearing loss/ANSD
    Looks for OTOF, PJVK, AIFM1, LOXHD1 and many other genes known to cause ANSD or related synaptopathies. Results guide counseling and implant decisions. PMC+1

14. Metabolic testing (glucose/HbA1c, thyroid, B12 as indicated)
    Screens for systemic causes of neuropathy that may affect the auditory nerve. PMC

15. Autoimmune/rheumatologic labs (as indicated)
    Considered if the history suggests immune-mediated inner ear disease. PMC

D) Electrodiagnostic (objective physiology)

16. Otoacoustic emissions (OAEs)
    Often present/normal in ANSD, showing outer hair cells amplify sound normally; this is the “OAE–ABR mismatch” part of the diagnosis. PMC+1

17. Auditory brainstem response (ABR)
    Absent or markedly abnormal despite present OAEs; this demonstrates defective neural synchrony to the brainstem. Children’s Hospital Colorado

18. Electrocochleography (ECochG) for cochlear microphonic (CM)
    A robust CM with absent ABR is strong evidence for ANSD; CM flips with stimulus polarity and confirms functioning hair cells with poor neural timing. ASHA Apps

19. Acoustic reflexes (objective version)
    Immittance instruments can measure reflex presence/absence; absent reflexes support neural pathway involvement. PMC

20. Cortical auditory evoked potentials (CAEP) / aided cortical testing
    Can document detection at the cortex (especially in infants) and help assess device benefit when ABR is unreliable. The BSA

E) Imaging

21. MRI of the internal auditory canals and brain (high-resolution)
    Looks for cochlear nerve deficiency, demyelination, or tumors (e.g., vestibular schwannoma) that can produce ANSD physiology. A 2024 review emphasizes imaging’s role in suspected ANSD. PMC

22. CT of the temporal bone (as needed)
    Shows bony inner-ear malformations and cochlear nerve canal size that correlate with nerve presence/size when MRI is equivocal. PMC

Important reality check about drugs for ANSD

There are no medications proven to reverse or cure auditory neuropathy itself. High-quality guidance emphasizes early detection, communication support, hearing-assistive technology trials, and cochlear implantation when appropriate. Medicines are used only to treat specific causes or associated conditions (for example: managing severe neonatal jaundice; treating confirmed congenital infections; addressing coexisting neuropathies)—but these do not directly fix the auditory nerve timing problem. Listing “20 drug treatments with doses” for ANSD would be misleading and unsafe. JCIH+2NIDCD+2

What clinicians may use medically (evidence-aware context, not prescriptive dosing)

• Management of severe neonatal jaundice (e.g., phototherapy/exchange transfusion) can reduce risk to auditory pathways, but this is perinatal critical care, not an ANSD cure. NIDCD

• Treating specific infections or metabolic problems when present (e.g., targeted antivirals or nutrition) follows disease-specific guidelines, not ANSD-specific drug therapy. NIDCD

• Avoidance of ototoxic medications where alternatives exist is general good practice in hearing care. JCIH

Because there is no standardized, proven medication for ANSD itself, providing “dosage/time/side-effects” tables here would risk implying efficacy that top guidelines do not support. Decisions about any medical therapy must be individualized by ENT/audiology and pediatric or adult medicine teams. JCIH

---

Dietary molecular supplements

No vitamin, herb, or over-the-counter supplement has been proven in controlled trials to treat ANSD or restore the auditory nerve’s timing. Some population research links overall diet quality and certain nutrients (antioxidants, magnesium, fish-based fats) with general hearing health, but these are associations, not ANSD cures. The safest advice is a balanced, heart-healthy diet and medical follow-up; avoid claims that pills can “fix” the nerve. PMC+2PMC+2

Because strong, direct ANSD evidence is lacking, giving “10 supplements with doses and mechanisms” would be speculative and not aligned with Cochrane-style standards. I’m intentionally not listing unproven products. Cochrane Library

---

Immunity booster / regenerative / stem-cell drugs

There are no FDA-approved stem-cell or “regenerative drug” treatments for hearing loss available in routine care. The FDA repeatedly warns consumers about clinics marketing unapproved stem-cell products for many diseases. Some hearing-related cell or gene therapy trials exist, but they remain experimental and not standard of care for ANSD at this time. Do not pursue such treatments outside legitimate clinical trials. Harvard Stem Cell Institute+2U.S. Food and Drug Administration+2

For safety, I won’t invent “six immunity-booster or stem-cell drugs with doses.” Instead: discuss trial opportunities with your ENT/audiologist and verify listings on reputable registries. Harvard Stem Cell Institute

Surgeries (what they are, and why)

1. Cochlear Implantation (CI)
   Procedure: Surgical placement of an electrode array in the cochlea with internal receiver; external sound processor worn behind the ear. Why: Bypasses dysfunctional IHC-synapse and delivers synchronized electrical stimulation to the auditory nerve, often improving speech understanding in ANSD. PubMed+1

2. Bilateral Cochlear Implantation
   Procedure: CI in both ears (simultaneously or sequentially). Why: May enhance sound localization and hearing in noise compared with one implant; candidacy individualized. PubMed

3. CI Revision/Upgrade (when needed)
   Procedure: Replacing faulty hardware or upgrading internal/external components. Why: Address device failure or improve function as technology advances. PubMed

4. Electrode array re-insertion/reposition
   Procedure: Surgical adjustment if insertion problems occur. Why: Optimize cochlear coverage and performance. PubMed

5. Diagnostic procedures under anesthesia (selected cases)
   Procedure: Imaging and intra-op measures to confirm cochlear nerve integrity when pre-op imaging is unclear. Why: Helps refine candidacy when the nerve status is uncertain. PubMed

When to see doctors

See an audiologist/ENT promptly if your infant fails a hearing screen, if speech is not developing on time, if you or your child hears but cannot understand speech, or if listening becomes much harder in noise. Also seek care after severe jaundice in a newborn, head trauma, new neurologic signs (balance, weakness), or medication exposures that might harm hearing. Early testing and early intervention improve outcomes across language, learning, and social well-being. JCIH+1

What to eat and what to avoid

Eat: A balanced, heart-healthy diet (vegetables, fruits, whole grains, lean protein, fish) supports overall and vascular health, which correlates with better hearing trajectories in population studies. Avoid: Relying on supplements that claim to “cure” hearing loss; there’s no proven pill for ANSD. Keep caffeine/alcohol within general health limits; no strong trial evidence shows that restricting them treats inner-ear disorders broadly, and none shows benefit for ANSD. Focus on medical follow-up and technology rather than “ear vitamins.” PMC+2Cochrane+2

Frequently asked questions (FAqs)

1) Can auditory neuropathy go away on its own?
Some infants show changes over time, but most people need ongoing management. Early, steady language access is the priority so no developmental windows are missed. JCIH

2) Why can I hear sounds but not understand speech?
Because the timing of nerve signals is disrupted; speech sounds smear together, especially in noise. PMC

3) Will hearing aids help?
They may help some, especially with added remote-mic systems, but not everyone benefits. A trial with careful speech testing guides decisions. ASHA Apps

4) Are cochlear implants effective in ANSD?
Many children with ANSD obtain speech outcomes similar to non-ANSD sensorineural loss after CI, especially when candidacy is appropriate and therapy is consistent. PubMed+1

5) Is one implant or two better?
Bilateral CI can improve localization and hearing in noise for some candidates; specifics are individualized by the CI team. PubMed

6) If OAEs are normal, why do I still have trouble?
OAEs show outer hair cells work; ANSD affects the synapse or nerve, so ABR and speech understanding suffer. NIDCD+1

7) Should we wait before starting therapy?
No—start early intervention right away while device decisions proceed. Early language access drives outcomes. JCIH

8) Could genes be involved?
Yes, some cases are genetic (e.g., synaptopathies). Genetic counseling/testing may clarify prognosis and CI expectations. PMC

9) Are there medicines to fix ANSD?
No medicine is proven to correct the neural timing problem. Care focuses on technology, therapy, and cause-specific management when applicable. JCIH+1

10) Do supplements help?
No supplement has been shown in trials to treat ANSD. General diet quality supports overall health but is not a cure. PMC

11) Are stem-cell treatments available?
Not in standard care. FDA warns against unapproved stem-cell clinics; consider only IRB-approved clinical trials. U.S. Food and Drug Administration+1

12) What tests are most important?
Combined ABR + OAE, age-appropriate behavioral audiology, and speech perception in quiet/noise; sometimes imaging/genetics. NIDCD+1

13) Why is background noise so hard?
Neural desynchrony masks the fine timing cues needed to separate speech from noise. PMC

14) What if progress with devices is slow?
Re-evaluate candidacy (including CI), optimize settings, intensify therapy, and ensure full-time device use; consider visual language supports. JCIH

15) What’s the long-term outlook?
With early, consistent language access and appropriate technology, many children achieve strong communication and literacy; adults can benefit from tech + strategies. Outcomes vary by lesion site and support. PubMed+1
