Document Summary
Dementia: gradual deterioration of intellectual and cognitive abilities that is not irreversible. If someone had a brain injury it is not dementia because things stay table or they go back to normal but with dementia is gets worse: deterioration can happen: step wise vs. slowly progressive. Slowly progressive occurs over years with no dramatic change. Differentiating is good because it allows for more accurate treatment. Family history- specific genotype that exists and increases your chance of getting the disorder. Cognitive reserve hypothesis- those who exercise cognitive abilities and gain more knowledge (neuro connections) and have a more sophisticated brain have a higher cognitive reserve (you can go further cognitively) before deficits give you a disability. Recent research shows the physical exercise keeps people cognitive stronger for longer as well: of canadians with dementia are institutionalized. First stage- forgetting names, places and people. Second stage- confusion, disoriented with time and place and poor judgment: neuropathology.
