Question 2

How do cholinesterase inhibitors improve the learning and memory of people who are suffering from Alzheimer's Disease?

Accepted Answer

A)  Cholinesterase inhibitors will increase the levels of acetylcholine in the brain.This will increase the neural functioning in brain regions associated with learning and memory.
B)  Cholinesterase inhibitors will decrease the levels of acetylcholine in the brain.This will increase the neural functioning in brain regions associated with learning and memory.
C)  Cholinesterase inhibitors will increase the levels of testosterone in the brain.This will increase the neural functioning in brain regions associated with learning and memory.
