Learning About Infant Hearing Loss

Every year, about 12,000 babies are born with hearing loss


1/3 genetic

1/3 non-genetic

1/3 unknown

Syndromic or non-syndromic


Usher’s Syndrome

CX26 gene mutation

Non-Genetic and Unknown Causes


Trauma before or during birth

Low birth weight

Bacterial and viral infections (e.g., meningitis)



Research is under way to reduce number of unknown causes

Scientists think half are genetic and half are non-genetic

Cochlear Implants: The Debate

Access to hearing world vs. identity within Deaf culture (social and psychological)

Medical ethics

Actual effectiveness

Not maximizing ability to perceive sounds

Cognitive development associated with the choice of language


The Deaf Community
