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]
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.
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 prion induces normally-folded proteins to take on the misfolded phenotype in an exponential cascade. These sheets form small chains which aggregate and cause cell death. Massive cell death forms lesions in the brain which lead to degeneration of physical and mental abilities and ultimately death. [15]
Dementia is a devastating condition that impacts up to 10 percent of older adults. And while there's no cure, getting diagnosed early can help patients get on a treatment plan and families prepare ...
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.
