Alzheimer's disease is associated with a shortage of acetyl-
choline.
GABA is short for gamma-aminobutyric acid. It is an inhibitory
transmitter, meaning it makes cells less excitable, and it helps the
brain maintain muscle control.
Serotonin is an inhibitory transmitter that helps the brain regu-
late acetylcholine.
