Sleep disruption after mild brain injury may drive chronic post-traumatic headaches

Official title: Role of Sleep Disruption after mTBI as a Driver of Chronic Post-traumatic Headache

Funded at Seattle Inst for Biomedical/clinical Res · NIH-11353962 · Data updated 2026-11-12

A study of people who have had a mild traumatic brain injury to see if sleep problems help explain why headaches linger, and whether a drug called prazosin could help.

Who could benefit from this research

Could help

Adults with a history of mild traumatic brain injury experiencing persistent post-traumatic headaches.

Less likely to help

Individuals without post-traumatic headaches after mTBI or those not experiencing sleep-related symptoms may have limited direct benefit.

What this research studies

If you’ve had a mild traumatic brain injury and ongoing headaches, this project looks at whether poor sleep plays a key role. The researchers will study how glymphatic brain clearance, which is influenced by sleep and noradrenergic signals, relates to post-traumatic headaches. They will test how repetitive impacts and blast injuries affect sleep-related brain clearance and whether prazosin can restore function and reduce symptoms. The team has preliminary mouse data suggesting prazosin improves glymphatic flow and headache-like symptoms, which they will extend to further experiments. The goal is to identify whether modulating sleep-related brain pathways can lessen chronic headaches after mTBI.

Why it matters

Potential benefit: If successful, the project could lead to new sleep- and drug-based strategies to reduce chronic headaches after head injuries.

How similar studies have gone: Preclinical data in mice show prazosin can improve glymphatic function and PTH symptoms, supporting translation to human studies.
