2026 Research Grant Spotlight

The Brain Aneurysm Foundation is proud to support groundbreaking research aimed at improving outcomes for patients and ultimately preventing ruptures. Each week, we’ll highlight one of our 2026 funded researchers and provide a brief overview of their project and its potential impact on patients, families, and the future of care.

Enhancing Neurolysin-Mediated Neuroprotection after Subarachnoid Hemorrhage using Pyridine Piperazine Derivatives

This project is focused on identifying new treatment targets for people who have experienced a ruptured brain aneurysm (subarachnoid hemorrhage, or SAH). Researchers are studying a promising drug that may reduce inflammation, protect brain cells from damage, and improve blood flow in the brain after the rupture. By testing whether this treatment can lessen neurological injury and improve recovery, the team hopes to lay the foundation for a targeted therapy that helps brain aneurysm survivors recover from brain damage and achieve better long-term outcomes.

This project is funded by the Virginia Comstock Tocci Chair of Research and the Froggy’s Drive Chair of Research

The Facts

1 in 50 people in the U.S. has an unruptured brain aneurysm
A brain aneurysm ruptures every 18 minutes
Early detection is critical as most brain aneurysms are treatable
The federal government spends only $3.02 per year on brain aneurysm research for each person afflicted

Our Impact

The Brain Aneurysm Foundation is the leading advocacy organization supporting education, research, and policy to transform the treatment of brain aneurysms. Funds raised are used for disease awareness efforts and grants that provide support to academic researchers studying the underlying biology of aneurysms or developing new treatment methods. Grantees include leading academic researchers whose work includes efforts to develop biomarkers to better predict and develop potential therapeutics for aneurysms, understand the impact of genetics on rupture outcomes, and create new device technology, drug delivery and robotic approaches to evolve treatment. The BAF has committed nearly $6 million to fund dozens of research efforts in the U.S. and Canada.

Donate

Your donation to the Brain Aneurysm Foundation goes directly to critical research efforts focused on reducing the incidence of brain aneurysm ruptures, to create new diagnostics to better prevent ruptures and interventions to transform treatment. Funds are also used to support our education initiatives as we work to advance awareness of the signs of brain aneurysms amongst those at risk, as well as providers and emergency responders.
