What is Early-Onset Alzheimer’s Disease?
Early-onset Alzheimer’s disease is a form of dementia that develops before age 65. It affects how the brain processes memory, thinking, and behavior. Over time, these changes can interfere with everyday tasks and independence.
Although it is less common than later-life Alzheimer’s disease, it can have a significant impact during working and family years.
What causes it?
The exact cause isn’t fully understood. Changes in the brain, specifically protein buildup that damages nerve cells, play a major role. A family history of Alzheimer’s disease can increase risk, and rare inherited gene changes may lead to earlier onset.
Symptoms
Early-onset Alzheimer’s disease often begins with subtle changes that gradually become more noticeable.
Common symptoms include:
- Forgetting recently learned information
- Trouble solving everyday problems or managing tasks
- Confusion about time or location
- Difficulty finding words or following conversations
- Misplacing items frequently
- Changes in mood, personality, or social behavior
As the condition progresses, symptoms may include:
- Severe memory loss
- Increased confusion
- Difficulty speaking, walking, or swallowing
How is it diagnosed?
Providers use a combination of tools to understand what’s happening. This often starts with a detailed medical history and questions about memory and behavior.
Additional testing may include:
- Cognitive assessments to evaluate thinking and memory
- Brain imaging, such as MRI or CT scans
- Lab tests to rule out other conditions
In some cases, more advanced testing may be recommended to understand brain function better.
How is it treated?
There is currently no cure for early-onset Alzheimer’s disease, but treatment can help manage symptoms and support daily life.
Common approaches include:
- Medications that support memory and thinking
- Strategies to manage mood and behavior changes
- Regular physical activity and mental stimulation
As the condition progresses, care focuses on safety, comfort, and maintaining quality of life. Planning and building a strong support system can make a meaningful difference.
