Answer to Question 1

ANS: A, C, D
Parkinson's Disease is the result of a deficiency of the neurotransmitter dopamine, a reduction of dopamine receptors, and the accumulation of Lewy Bodies, especially in the basal ganglia. The presence of neurofibrillary tangles and amyloid plaques in the brain is seen in Alzheimer's Dis-ease.

Answer to Question 2

ANS: C
The symptoms are also often masked by normal aging changes and conditions common in older adults. Polydipsia often does not occur due to the decreased thirst mechanism in older adults, polyphagia is often not recognized due to normal appetite declines associated with aging, and polyuria is often not recognized due to frequent urinary tract infections in older adults. Present-ing symptoms usually occur very slowly. Type 2 diabetes mellitus is very common in older adults. There are symptoms of diabetes mellitus in older adults; however, they may be different than those seen in younger adults.
