What this research studies

This project uses advanced digital pathology and computational algorithms to examine thousands of brain tissue slides from multiple brain banks to find patterns of tau, beta‑amyloid, pTDP‑43, alpha‑synuclein, vascular injury, and other changes after repeated head impacts. The team will harmonize neuropathology and clinical records from collections such as UNITE, the Framingham Heart Study, and the Boston University brain bank to link tissue findings with symptoms and histories. By comparing cases across diverse populations, they aim to explain why some people develop dementia after repetitive impacts while others do not. The work focuses on archived human brain samples and linked clinical data to discover markers that could improve diagnosis and guide future patient-facing tests or trials.

Who could benefit from this research

Good fit: People with a history of repetitive head impacts—for example from contact sports or military service—or family members willing to donate brain tissue and share medical records would be the most relevant participants or donors.

Not a fit: People without a history of repetitive head impacts or those seeking an immediate treatment are unlikely to receive direct benefit from this tissue‑based, diagnostic discovery work.

Why it matters

Potential benefit: If successful, this work could help doctors recognize and distinguish head‑impact–related brain disease earlier and guide development of targeted tests and treatments.

How similar studies have performed: Prior brain‑bank and neuropathology research has identified CTE and mixed pathologies after head injury, but large‑scale digital pathology and harmonized, multi‑bank computational analyses of this scope are relatively new.
