[1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
Researchers have found a link between hearing loss and dementia. A recent study shows that people with hearing loss not using hearing aids had a 42% higher risk of all-cause dementia than people ...
The most common type of congenital hearing loss in developed countries is DFNB1, also known as connexin 26 deafness or GJB2-related deafness.
