How does Alzheimer's disease affect the brain?
In Alzheimer’s, most of the time, brain cells get two types of flaws:
These damage healthy cells. The damaged cells die, causing memory loss, speech problems, confusion, and mood swings.
Brain cells affected by the disease also make fewer chemicals that nerves use to send messages to each other.
- Neurofibrillary tangles, which keep important things from moving from one part of the cell to another
- Beta-amyloid plaques, which build up between nerve cells instead of breaking down as they should
