Alzheimer’s disease is a progressive brain disorder that slowly destroys memory, thinking skills, and eventually the ability to carry out even simple tasks. It is the most common cause of dementia, a general term for a decline in mental ability that interferes with daily life.

Key Facts:

Cause: Alzheimer’s is associated with abnormal buildups of proteins in the brain—amyloid plaques and tau tangles—which damage and kill brain cells.
Symptoms:
- Memory loss (especially of recent events)
- Confusion and difficulty thinking or concentrating
- Trouble with language (finding words, following conversations)
- Changes in mood and behavior
- Difficulty with familiar tasks and decision-making
Stages: The disease progresses from mild (forgetfulness) to moderate (confusion, trouble with daily tasks) to severe (inability to communicate or care for oneself).
Who is affected: Most people with Alzheimer’s are 65 or older, but it can also affect younger individuals (known as early-onset Alzheimer’s).
Treatment: There is no cure, but some medications and therapies can help manage symptoms or slow progression for a time. Supportive care and lifestyle adjustments also help.
Prevention: There’s no guaranteed way to prevent it, but a healthy lifestyle—regular exercise, a balanced diet, mental stimulation, and social engagement—may reduce the risk.
