Alzheimer’s disease is associated with a decrease in which of the following neurotransmitters?
The answer is A) Acetylcholine. The neurotransmitter norepinephrine is also decreased in Alzheimer’s disease. Several medications target the breakdown of acetylcholine in Alzheimer’s and thus work to increase this neurotransmitter's levels. Medications that are acetylcholinesterase inhibitors include Donepezil, Rivastigmine, Galantamine, and Tacrine.
