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 ...
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [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.
One of the genes that leads to deafness and a white coat in cats when mutated, KIT, [56] has been found to increase MITF expression. [57] Lethal white syndrome is a syndrome in horses caused by mutations in both copies of EDNRB. It leads to death from intestinal pseudo-obstruction due to Hirschsprung's disease.
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]
A new study found the biggest risk factors and predictors at 60 for dementia at 80. Neurologists weigh in on the research and share ways to prevent dementia.
Hearing loss has multiple causes, including ageing, genetics, perinatal problems and acquired causes like noise and disease. For some kinds of hearing loss the cause may be classified as of unknown cause. [citation needed] There is a progressive loss of ability to hear high frequencies with aging known as presbycusis. For men, this can start as ...
An analysis of locks of Ludwig van Beethoven’s hair suggest he had lead poisoning. It may have contributed to chronic ailments, deafness and — ultimately — his demise.
Dementia is a complicated condition, and researchers are still unpacking a lot about its underlying causes. However, there are some things doctors generally agree on when it comes to prevention ...
