Deafness in animals can occur as either unilateral (one ear affected) or bilateral (both ears affected). This occurrence of either type of deafness seems to be relatively the same in both mixed-breed animals and pure-breed animals. [5] Research has found a significant association between deafness in dogs and the pigment genes piebald and merle ...
This condition was first discovered in 1995 by Melberg et al. when they described 5 members of a 4-generation Swedish family where cerebellar ataxia and sensorineural deafness presented as an autosomal dominant trait, 4 of them had narcolepsy and 2 had diabetes mellitus. The oldest members had psychiatric symptoms, neurological anomalies, and ...
Due to these lesions, Wernicke believed that individuals with receptive aphasia had a limited deafness for certain sounds and frequencies in speech. [8] After Wernicke, came Kussmaul in 1877 who attempted to explain why auditory verbal agnosia, also known as word deafness, occurs. Contrary to Wernicke's explanations, Kussmaul believed auditory ...

She pioneered universal newborn hearing screening in the early 1960s and spent over 30 years advocating for its adoption in hospitals, as well as for the provision of hearing aids to infants displaying hearing loss.

Hearing loss is a partial or total inability to hear. [5] Hearing loss may be present at birth or acquired at any time afterwards. [6] [7] Hearing loss may occur in one or both ears. [2] In children, hearing problems can affect the ability to acquire spoken language, and in adults it can create difficulties with social interaction and at work. [8]
Deafness can occur in white cats with yellow, green or blue irises, although it is mostly likely in white cats with blue irises. [4] In white cats with one blue eye and one eye of a different color (odd-eyed cats), deafness is more likely to affect the ear on the blue-eyed side. [1] Approximately 50% of white cats have one or two blue eyes. [5]
People who have cognitively demanding jobs are much less likely to experience cognitive decline and dementia in their 70s, a study finds. Routine jobs raise the risk of cognitive decline by 66% ...
