Question

Quizplus · Accepted Answer

Patients with Alzheimer's disease have a deficit of acetylcholine in the brain, which is involved in memory and learning processes. Therefore, the levels of acetylcholine are abnormally low. On the other hand, glutamate is an excitatory neurotransmitter that is involved in learning and memory as well, but high levels of glutamate can cause damage to neurons. Patients with Alzheimer's disease tend to have abnormally high levels of glutamate, which can contribute to the neurodegenerative process. Therefore, the best choice is B, which indicates low levels of acetylcholine and high levels of glutamate.
