According to the Alzheimer’s Foundation of America (AFA), Alzheimer’s disease is a progressive, degenerative disorder that attacks the brain’s nerve cells, or neurons, resulting in loss of memory, deterioration of thinking and language skills, and behavioral changes. These neurons, which produce the brain chemical, or neurotransmitter, acetylcholine, break connections with other nerve cells and ultimately die. For example, short-term memory fails when Alzheimer’s disease first destroys nerve cells in the hippocampus, and language skills and judgment decline when neurons die in the cerebral cortex.
