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.
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]
This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
The association between age-related hearing loss and Alzheimer's disease was found to be nonsignificant, and this finding supports the hypothesis that hearing loss is associated with dementia independent of Alzheimer pathology. [32] There are several hypotheses about the underlying causal mechanism for age-related hearing loss and cognitive ...
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 ...
Again, dementia is a complex disease—and this is just one study. However, other studies have also found a link between having a lower level of education and a higher risk of developing dementia.
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.
