Question

Quizplus · Accepted Answer

Cholinesterase inhibitors work by blocking the enzyme that breaks down acetylcholine, a neurotransmitter important for learning and memory. This action increases acetylcholine levels in the brain, which can temporarily mitigate the symptoms of Alzheimer's disease. They do not reverse existing damage or stop the accumulation of amyloid plaques and neurofibrillary tangles.
