Overview
MCI is a description of severity, not a cause. Some people with MCI remain stable, some improve when a contributing factor is treated, and some progress to dementia.
Common symptoms
- Noticeable forgetfulness confirmed by testing
- More effort needed for complex tasks
- Independence in daily activities is largely preserved
How it progresses
Outcomes vary widely. Regular follow-up matters more than any single test result, because the trajectory is the most informative finding.
How it is diagnosed
Cognitive testing, review of medications and mood, blood work, and often MRI. Biomarker testing may be considered when an Alzheimer's cause is suspected and would change management.
Treatment
Address sleep, hearing, mood, vascular risk factors, and medications that dull thinking. Some people with MCI due to Alzheimer's disease may be candidates for disease-modifying therapy.
What families should know
- MCI is not the same as dementia
- This is the best time for legal and financial planning
- Repeat testing is how the picture becomes clear
Questions to ask your doctor
- What do you think is causing the MCI?
- Am I a candidate for biomarker testing?
- What can I do to reduce risk of progression?
