If your baby has been diagnosed with or you suspect has auditory neuropathy — what does this mean, here is what the evidence says.
The short answer
Auditory neuropathy spectrum disorder (ANSD) is a hearing condition where the inner ear (cochlea) detects sound normally, but the signal is not transmitted properly to the brain via the auditory nerve. This means your baby may pass one type of hearing test (OAE) but fail another (ABR). ANSD affects about 10-15% of children diagnosed with permanent hearing loss. The hearing ability of children with ANSD is highly variable — some hear almost normally, others have severe hearing loss, and hearing can fluctuate. Early intervention with hearing aids or cochlear implants, combined with speech therapy, gives the best outcomes.

“Fever itself is not an illness — rather, it is a sign or symptom that the body is fighting an infection. Fever stimulates certain defenses, such as the white blood cells, which attack and destroy invading bacteria.”
Thousands of parents search for this exact thing. You are not alone.
What Parents Should Know
According to NIH, Hands & Voices, AAP guidelines, auditory neuropathy spectrum disorder (ANSD) is a hearing condition where the inner ear (cochlea) detects sound normally, but the signal is not transmitted properly to the brain via the auditory nerve. This means your baby may pass one type of hearing test (OAE) but fail another (ABR). ANSD affects about 10-15% of children diagnosed with permanent hearing loss. The hearing ability of children with ANSD is highly variable — some hear almost normally, others have severe hearing loss, and hearing can fluctuate. Early intervention with hearing aids or cochlear implants, combined with speech therapy, gives the best outcomes. At 0-3 months (diagnosis), aNSD is often identified through newborn hearing screening, particularly in NICU babies (who are at higher risk). The classic finding is present otoacoustic emissions (OAEs) but absent or abnormal auditory brainstem response (ABR). Risk factors include prematurity, hyperbilirubinemia, hypoxia, and certain genetic conditions. After diagnosis, your baby will need regular audiologic monitoring because hearing levels in ANSD can change over time — sometimes improving, sometimes worsening. It is generally considered normal when your baby has been diagnosed with ANSD and is receiving regular audiological monitoring. However, you should contact your pediatrician promptly if your baby suddenly stops responding to sound completely — seek urgent audiologic and medical evaluation.
Normal vs. Concerning
By Age
What to expect by age
0-3 months (diagnosis)
ANSD is often identified through newborn hearing screening, particularly in NICU babies (who are at higher risk). The classic finding is present otoacoustic emissions (OAEs) but absent or abnormal auditory brainstem response (ABR). Risk factors include prematurity, hyperbilirubinemia, hypoxia, and certain genetic conditions. After diagnosis, your baby will need regular audiologic monitoring because hearing levels in ANSD can change over time — sometimes improving, sometimes worsening.
3-6 months
During this period, the audiologist will work to understand how your baby perceives sound. Behavioral observation is added to objective tests. Hearing aids may be trialed, even though predicting benefit is harder with ANSD than with typical hearing loss. Visual communication strategies (sign language, visual cues) are recommended to begin early, regardless of whether hearing aids are used, to support language development during this critical window.
6-12 months
Language development is closely monitored. If your baby is not showing expected auditory responses or language development despite hearing aid use, cochlear implant evaluation may be recommended. Cochlear implants can be very effective for ANSD because they bypass the auditory nerve's synchrony problem and directly stimulate nerve fibers. Early cochlear implantation (before 12 months when possible) yields the best speech outcomes.
1 year+
Children with ANSD who receive appropriate intervention (hearing aids, cochlear implants, and/or sign language) can develop strong communication skills. Some children with ANSD have fluctuating hearing — they may hear better some days than others, which can be confusing for parents and caregivers. Close collaboration between your audiologist, speech-language pathologist, and early intervention team is essential. Some forms of ANSD improve spontaneously, particularly in premature babies.
What to Tell Your Pediatrician
- Describe when you first noticed has auditory neuropathy — what does this mean and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby does not seem to respond to your voice or environmental sounds.
- Mention if your baby is not babbling or showing expected communication development.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.
What Should You Do?
When to take action
- Your baby has been diagnosed with ANSD and is receiving regular audiological monitoring
- Your baby is receiving early intervention services and making communication progress
- Your baby's ANSD appears to be improving on follow-up testing — this can happen, especially in premature babies
- Your baby does not seem to respond to your voice or environmental sounds
- Your baby is not babbling or showing expected communication development
- You notice your baby's hearing seems to fluctuate — some days better, some worse
- You have questions about hearing aids vs. cochlear implants for your child
- Your baby suddenly stops responding to sound completely — seek urgent audiologic and medical evaluation
- You are concerned that your baby is not receiving adequate communication support and early intervention — contact your state's early intervention program or Hands & Voices organization
What You Can Do at Home
- Keep track of when you notice has auditory neuropathy — what does this mean — noting the time of day, duration, and any triggers can help your pediatrician.
- Remember that your baby has been diagnosed with ANSD and is receiving regular audiological monitoring — this is generally within the range of normal.
- At 0-3 months (diagnosis), focus on observation rather than intervention unless your pediatrician advises otherwise.
- Follow any care instructions from your pediatrician. Keep a written log of symptoms to bring to appointments.
- While monitoring at home, seek immediate care if your baby suddenly stops responding to sound completely — seek urgent audiologic and medical evaluation.

My Baby Has Congenital CMV (Cytomegalovirus)
Congenital cytomegalovirus (CMV) infection occurs when CMV is passed from mother to baby during pregnancy. It is the most common congenital infection, affecting about 1 in 200 babies. Most babies with congenital CMV (about 90%) have no symptoms at birth and do well. However, about 10% are symptomatic at birth and may have hearing loss, vision problems, developmental delays, or other complications. CMV is also the leading non-genetic cause of hearing loss in children. Early identification and antiviral treatment can improve outcomes for symptomatic babies.
My Baby Seems Extremely Sensitive to Touch, Sound, or Textures
Some babies are naturally more sensitive to sensory input — touch, sound, light, textures, and movement. This sensory sensitivity exists on a spectrum, and having a sensitive baby does not automatically mean there is a disorder. However, when sensory responses are extreme enough to interfere with feeding, sleeping, developmental progress, or daily life, an evaluation by a pediatric occupational therapist can help. Sensory processing challenges are common, responsive to early intervention, and do not define your child's potential.

My Baby's Head Shape Looks Abnormal
Many babies develop temporary head shape irregularities that are completely normal. A cone-shaped head from vaginal delivery reshapes within days. Mild positional flattening (plagiocephaly) from sleeping on the back is very common and usually improves with repositioning and tummy time. However, head shape changes involving ridges, a persistently bulging fontanelle, or rapid head growth changes should be evaluated to rule out craniosynostosis.
Achondroplasia (Dwarfism) in Babies
Achondroplasia is the most common form of short-limbed dwarfism, affecting about 1 in 15,000 to 40,000 births. It is caused by a mutation in the FGFR3 gene and is usually apparent at birth with characteristic features including short limbs, a larger head, and a prominent forehead. Intelligence is normal. With monitoring for specific complications and supportive care, children with achondroplasia lead full, active, and independent lives.
Adenoid Hypertrophy and Breathing
Adenoids are lymphoid tissue located behind the nose that help fight infection in young children. When adenoids become enlarged (adenoid hypertrophy), they can block the nasal airway, causing chronic mouth breathing, snoring, nasal speech, and sleep-disordered breathing. Enlarged adenoids are most common between ages 2-7 and are a leading cause of obstructive sleep apnea in young children. Treatment ranges from watchful waiting and nasal steroids to surgical removal (adenoidectomy) if breathing or sleep is significantly affected.
Adrenoleukodystrophy (ALD) in Babies
X-linked adrenoleukodystrophy (X-ALD) is a genetic disorder affecting about 1 in 17,000 newborns, caused by mutations in the ABCD1 gene on the X chromosome. It primarily affects boys and impairs the breakdown of very long-chain fatty acids (VLCFAs), which accumulate and damage the myelin sheath in the brain and the adrenal glands. The most severe form, cerebral ALD, typically affects boys between ages 4-10 with rapid neurological decline. Newborn screening now enables early detection, and hematopoietic stem cell transplant or gene therapy performed before significant brain involvement can be life-saving.
