ANS: D
Decreased levels of acetylcholine are thought to produce many of the behavioral symptoms of Alzheimer's disease. The inhibiting action the drug has on cholinesterase will slow down the breakdown of acetylcholine and so delay the onset of symptoms. The other neurotrans-mitters (GABA, dopamine, and serotonin) are not currently believed to play a role in Alz-heimer's disease.
