Late-onset unexplained epilepsy and dementia risk

Late-onset Unexplained Epilepsy as a Risk Factor for Dementia

NIH-funded research Massachusetts General Hospital · NIH-11298920

This project looks at people who start having unexplained seizures after age 55 to find which individuals are more likely to develop Alzheimer’s or other dementias.

What this research studies

If you join, researchers will collect detailed clinical information, brain scans, and dementia-related biomarkers and follow your thinking and memory over time. They will combine seizure features, imaging, fluid biomarkers, and cognitive tests to sort people into biological subtypes. The team will look for hidden Alzheimer’s or blood-vessel-related brain changes that might explain why some people with late-onset seizures later get dementia. The goal is to use this data-driven approach to predict risk and point toward targeted ways to prevent dementia.

Who could benefit from this research

Good fit: Ideal candidates are people aged about 55 or older who have recently developed epilepsy without a clear cause and who do not already have dementia.

Not a fit: People whose seizures have a known cause (for example, stroke or tumor), those with childhood-onset epilepsy, or those who already have dementia are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could help identify which patients with late-onset unexplained epilepsy are at high risk for dementia and lead to earlier, more personalized prevention strategies.

How similar studies have performed: Previous research has shown that late-onset unexplained epilepsy is linked to higher dementia risk and Alzheimer-type brain changes, but using comprehensive biomarker-driven subtyping to predict individual risk is a newer approach.
