Familial Alzheimer's disease mutations commonly used in animal models. Rodent animal models of Alzheimer's disease are commonly used in research as rodents and humans have many of the same major brain regions and neurotransmitter systems. [5] These models are small, easy to house, as well as breed very well. [26]
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 ...
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 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 ...
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.
Researchers compared key dementia risk factors across the two groups, including a history of smoking, depression, alcohol-related disorders, diabetes, hypertension, hearing loss and obesity.
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.
Hearing loss is associated with Alzheimer's disease and dementia with a greater degree of hearing loss tied to a higher risk. [12] There is also an association between type 2 diabetes and hearing loss .
