Can AI prevent strokes? An NAU student’s groundbreaking research

In a groundbreaking study that could revolutionize brain health care, a Northern Arizona University doctoral student is harnessing the power of artificial intelligence to tackle one of medicine’s most daunting challenges: preventing hemorrhagic strokes caused by ruptured brain aneurysms.

Holly Berns, a bioengineering student at NAU, is spearheading an innovative project that’s caught the attention of the Brain Aneurysm Foundation. Her research focuses on the circle of Willis, a crucial network of arteries at the brain’s base, and how its variations might serve as early warning signs for aneurysm formation.

“This research could advance the field of aneurysm detection and guide treatment for the nearly 6.7 million Americans who live with an unruptured cerebral aneurysm,” Berns explained in a news release.

Berns’ hypothesis

Berns’ hypothesis is intriguing in its simplicity. She believes that certain angles within the circle of Willis might predict or even cause abnormal blood flow at artery junctions, potentially leading to aneurysm formation. To test this, she’s employing cutting-edge AI and machine learning algorithms to analyze patient imaging data, calculating and categorizing these critical angles in both male and female patients.

If proven correct, Berns’ work could dramatically alter the landscape of aneurysm treatment. It may enable doctors to take proactive measures to prevent ruptures, which are often catastrophic. According to the Brain Aneurysm Foundation, ruptured brain aneurysms are fatal in about 50% of cases, and survivors frequently face significant, permanent brain damage.

Health equity

Moreover, this research has profound implications for health equity. Women are 50% more likely to experience a brain aneurysm than men, while Hispanic and Black individuals face twice the risk of aneurysm rupture compared to their white counterparts.

Berns’ vision extends beyond mere detection. “Identifying patients who are at-risk would allow for proactive screening and follow-ups, as well as informed treatment methods,” she said. This approach could significantly reduce the incidence of subarachnoid hemorrhage from aneurysm ruptures, potentially saving lives and reducing healthcare costs.

Recognition & significance

The Brain Aneurysm Foundation will recognize Berns’ groundbreaking work at their 18th Annual Research Grant Symposium in Boston on September 12. She’ll be conducting this vital research alongside fellow Ph.D. student Steve Schwartz in the coming year.

For Arizonans, this local research represents a beacon of hope in the fight against a condition that affects millions nationwide. As our state continues to grow as a hub for medical innovation, studies like Berns’ underscore the critical role of Arizona’s universities in pushing the boundaries of healthcare and technology.
