IV. Essential question
Learning About Infant Hearing Loss
Every year, about 12,000 babies are born with hearing loss
Gene is inherited from a parent
400 kinds have been identified!
Syndromic or non-syndromic
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
Interventions and Treatments for Infant Hearing Loss
Surgery and medications
Family support systems
Communication and language options
What is it?
How does it work?
What does it look like?
How well can an implant recipient actually hear?
Cochlear Implants: The Debate
Access to hearing world vs. identity within Deaf culture (social and psychological)
Not maximizing ability to perceive sounds
Cognitive development associated with the choice of language
The Deaf Community
Supportive, strong community
Does not view hearing loss as a disability
Rich history and language (e.g., ASL)
Children with cochlear implants may have limited access to the Deaf community
If you were hard of hearing, would you want a cochlear implant? Why or why not?
