Whether long-term epilepsy speeds up brain aging, seen with PET and MRI scans
PET/MR Correlates of Accelerated Aging in Chronic Epilepsy
Researchers are using PET and MRI brain scans to look at whether adults with long-term focal epilepsy show signs of faster brain and memory aging than people their age.

What this research studies
You would have combined PET and MRI brain scans to look for signs of aging-related changes such as amyloid buildup, reduced metabolism, and altered brain structure and connectivity. The team will compare these imaging markers in adults with chronic focal epilepsy to people of the same age without epilepsy. You would also complete memory and thinking tests and share health and genetic information to find factors that increase or reduce risk for faster brain aging. The researchers aim to link imaging and clinical measures to cognitive function in people with long-standing epilepsy.
Who could benefit from this research
Good fit: Adults with long-standing focal epilepsy who are willing to travel for brain PET and MRI scans and neurocognitive testing would be ideal candidates.
Not a fit: People without a history of chronic epilepsy or those who cannot undergo PET/MRI (for example due to implanted devices, pregnancy, or inability to travel) would not be expected to benefit from participating.
Why it matters
Potential benefit: If successful, this work could help identify who with chronic epilepsy is at higher risk for faster brain aging and guide earlier monitoring or protective strategies.
How similar studies have performed: Previous imaging studies have linked epilepsy to cognitive decline and PET/MRI can detect aging biomarkers, but using these combined measures specifically to show accelerated brain aging in long-term focal epilepsy is relatively new.
