Alzheimer’s disease is an irreversible, progressive brain disorder that damages memory, behavioral, and cognitive skills. This condition causes brain cells to degenerate and die leading to many cognitive issues. Although the exact cause is unknown, it is thought to be due to a combination of genetic, lifestyle, and environmental factors. Due to its progressive nature, symptoms can vary from mild memory loss to complete lack of ability to respond to one’s surroundings. The memory impairments brought on by this disease can lead to specific problems with memory interference, which may be caused by dysfunction in working and semantic memory. When conducting experiments on Alzheimer’s patients, there is also the added difficulty of the individual having trouble remembering the instructions and needing external cues to complete memory tasks. This chapter outlines the disease, its symptoms, risk factors, how it affects memory, and how exercise may be a prevention and treatment option.
