Answer to Question 1

Ans: D
Feedback:
Compelling evidence shows that drugs that inhibit ACh destruction or increase cholinergic activity can slow deterioration of memory and function. Cholinesterase inhibitors increase availability of ACh by interfering with the enzyme that breaks it down. These centrally acting drugs help elevate the level of ACh by decreasing the binding sites of acetylcholinesteras e, which lengthens the potential for cholineregic activity.

Answer to Question 2

Ans: A
Feedback:
Lewy body disease is sometimes mistaken for AD because of clinical similarity, but there are earlier and more prominent visual hallucinations, parkinsonian features, and disturbed behaviors. A distinguishing characteristic is significant adverse reactions to antipsychotic drugs.
