What is Alzheimer’s disease?
Alzheimer’s disease is a condition that affects the brain. The symptoms are mild at first and become more severe over time. It is named after Dr. Alois Alzheimer, who first described the condition in 1906Trusted Source.

Common symptoms of Alzheimer’s disease include memory loss, language problems, and impulsive or unpredictable behavior.

One of the main features of the condition is the presence of plaques and tangles in the brain. Another feature is a loss of connection between the nerve cells, or neurons, in the brain.

These features mean that information cannot pass easily between different areas of the brain or between the brain and the muscles or organs.
