McGill University’s Alain Ptito uses high resolution imaging equipment to get a closer look at how even minor brain trauma can have lasting effects.

As a young neuropsychologist, Alain Ptito was troubled by the sizeable number of his patients who suffered symptoms of traumatic brain injury after scans pronounced them recovered from their concussion.

“Insurance companies would say this is a psychological problem; let’s treat it with therapy,” he recalls.

But Ptito decided to trust his patients and investigate further. He has since made a career out of exploring new methods for using structural and functional magnetic resonance imaging (MRI) to probe brain trauma.

Today he is a professor of neurology and neurosurgery at McGill University, and a medical scientist at the Research Institute of the McGill University Health Centre. As he and others have shown in the last few years, mild traumatic brain injury often doesn’t show up on conventional scanners.

Canada Foundation for Innovation

The Canada Foundation for Innovation (CFI) was built on the ideals of thinking big and investing in areas that matter to Canadians. Since its creation in 1997, the CFI has ensured Canadian researchers have the tools — the cutting-edge labs, facilities and equipment — they need to push the frontiers of knowledge in all disciplines, and to contribute to the full spectrum of research — from discovery to technology development.
