The effectiveness of acetylcholinesterase inhibitors for temporarily treating the symptoms of Alzheimer's disease suggests that:
A) adrenergic receptors are not functioning correctly.
B) damage to brain tissue has occurred from excitotoxicity.
C) acetylcholinestase is responsible for the cognitive disturbances found in Alzheimer's disease.
D) cholinergic neurotransmission is diminished in Alzheimer's disease.

Question

Quizplus · Accepted Answer

Acetylcholinesterase inhibitors work by increasing the levels of acetylcholine in the brain, which is a neurotransmitter involved in cognitive function. This suggests that cholinergic neurotransmission is diminished in Alzheimer's disease, leading to the cognitive disturbances. A and B are not relevant factors in the efficacy of acetylcholinesterase inhibitors, and C is an oversimplification of the complex pathophysiology of Alzheimer's disease.
