Overview
Alzheimer's disease is the most common cause of dementia - a progressive decline in memory, thinking, and behavior that interferes with daily life.
Symptoms
- Memory loss that disrupts daily life
- Difficulty planning or solving problems
- Confusion with time or place
- Trouble finding words
- Changes in mood and personality
Causes
Abnormal protein deposits (plaques and tangles) damage and kill brain cells. Age is the biggest risk factor; genetics also play a role.
Types
- Early-onset Alzheimer's (before 65, often genetic)
- Late-onset Alzheimer's (most common)
Diagnosis
Diagnosed from a medical history, cognitive tests, neurological exam, and brain imaging. A definitive diagnosis of the underlying changes is only possible after death.
Treatment
No cure, but medicines can temporarily ease symptoms, and lifestyle and supportive care improve quality of life. Early planning helps.
Living with it
- Stay physically, mentally, and socially active
- Manage blood pressure, diabetes, and cholesterol
- Plan for safety (driving, finances, home)
- Build a care team and support network
- Eat a heart-healthy diet
Complications
- Loss of independence
- Wandering and falls
- Malnutrition and infections
- Caregiver stress
Frequently asked questions
Is Alzheimer's the same as dementia?
Not exactly. Dementia is the umbrella term for cognitive decline; Alzheimer's is the most common specific cause of dementia.
