St. F.X. Professor Develops Portable Brain Health Testing Device

A professor at St. Francis Xavier University is developing a more affordable and accessible alternative to magnetic resonance imaging (MRI) for brain health assessments, particularly aimed at rural residents of Nova Scotia. Dr. Erin Mazerolle, who joined the university in 2020, has observed firsthand the challenges patients face in securing timely access to MRI services, especially those living outside urban areas.

The current system in Nova Scotia often results in lengthy wait times for MRI scans, sometimes extending beyond a month. These delays can significantly impact patient care, pushing many individuals to seek private clinics where costs can exceed $1,000 per visit. This financial burden is a major concern for those without the means to afford such expenses.

Dr. Mazerolle’s research focuses on a technology known as functional near-infrared spectroscopy (fNIRS), a portable device that measures brain function through sensors placed on the scalp. This technology offers a promising alternative to traditional MRI scans by allowing for brain health tracking in a more accessible manner.

Innovative Approach to Brain Health

Dr. Mazerolle highlights the potential of fNIRS to provide critical insights into brain function. “This device fits in a backpack and could be used in various settings, making it a viable option for people who cannot easily access MRI facilities,” she explained. The technology operates by monitoring changes in blood oxygenation in the brain, a method that can reveal neurological functions without the need for the large, stationary MRI machines that typically cost between $1 million and $2 million.

The research involves initial evaluations to determine the reliability of fNIRS results in healthy individuals. If successful, the next phase will investigate its application in diagnosing conditions such as sports-related concussions and migraines. Dr. Mazerolle aims to ascertain whether the device can detect significant changes in brain function, similar to what can be identified through MRI scans.

“The unique aspect of fNIRS is that it emphasizes data collection over imaging,” Dr. Mazerolle noted. This shift allows healthcare providers to gather valuable information on brain health that could help guide diagnosis and treatment decisions.

Reducing Barriers to Access

One of the primary goals of Dr. Mazerolle’s research is to enhance access to brain health assessments for those who face barriers to MRI testing. This includes individuals who may have contraindications for MRIs, such as those with pacemakers, or those living in rural areas with limited transportation options.

The development of fNIRS could serve as a preliminary screening tool, potentially reducing wait times for MRI appointments by providing basic neurological data upfront. “This technology won’t replace MRI, but it could significantly alleviate the pressure on our current healthcare system,” Dr. Mazerolle stated.

By raising awareness about the importance of brain health and the impact of early interventions, Dr. Mazerolle hopes to empower individuals to take charge of their neurological well-being. She emphasizes the necessity of educating the public about the risks associated with multiple concussions and the significance of managing factors like blood pressure for overall brain health.

“More accessible technology means that we can reach more people and provide them with the information they need to make informed health decisions,” she added.

Dr. Mazerolle’s work at St. Francis Xavier University exemplifies a proactive approach to addressing healthcare disparities in Nova Scotia and beyond. As the research evolves, it may pave the way for innovative solutions that enhance brain health accessibility for all.
