Dr. Bradley MacIntosh
As an imaging physicist in the Brain Sciences Research Program at Sunnybrook Research Institute, Dr. MacIntosh is developing tools to study the human brain in health and disease. In particular, as explored in this story, he is working on ways to study blood flow in the brain and cerebral blood volume. His aim is to discover ways to improve diagnosis of cerebrovascular diseases like stroke and vascular dementia, and characterize better their progression. He was recently awarded an operating grant from the Canadian Institutes of Health Research to test whether aerobic exercise is an intervention that can combat covert stroke vascular disease, a condition that contributes to neurological impairment caused by damage to small blood vessels in the brain.
