Alzheimer's is a disease that causes changes in brain function. It is a type of dementia that affects your behavior and judgment. It also affects how you process information. You may have problems talking with others or remembering things. Some people have trouble solving problems and finding words when speaking. Alzheimer disease is not a normal part of aging. The disease gets worse over time.
Currently, there is no cure for Alzheimer disease. Treatment includes drugs to improve memory and slow down the worsening of the disease.
The disease initially involves the parts of the brain that control thought, memory, and language. Neurons involved with communication, metabolism, and repair are disrupted. Brain damage is caused by a substance called amyloid.
