Question

Quizplus · Accepted Answer

Alzheimer's disease is associated with a deficiency in acetylcholine, which is a neurotransmitter involved in memory and learning. This deficiency is caused by the degeneration of cholinergic neurons in the brain. While amyloid plaques and neurofibrillary tangles are characteristic features of Alzheimer's disease, they are not the primary cause of the deficiency in acetylcholine. Similarly, while dopamine dysfunction is implicated in other neurological disorders, such as Parkinson's disease, it is not directly involved in Alzheimer's disease.
