Our research program is directed at understanding neurovascular function in health and disease. Specifically, we have been studying the association between cerebral blood flow regulation, structural changes in the brain and the clinical outcomes of acute and chronic cerebrovascular injury. In acute neurovascular disorders, we have validated several novel indices of cerebral blood flow regulation which can now be used to predict the development of vasospasm in subarachnoid hemorrhage and hematoma expansion in patients with intraparenchymal hemorrhage.
The availability of these early non-invasive biomarkers will have a significant impact on early interventions to improve outcome in patients with subarachnoid and intraparenchymal hemorrhage. Similarly, in chronic neurovascular disorders associated with aging and neurodegenration, we have been examining the contribution of vascular disease to mobility impairment and cognitive decline. We have shown that our non-invasive biomarkers of vascular function are strongly associated with cerebral small vessel disease as well as motor and cognitive impairment.
Our goal is to expand these studies to include other neurological disorders such as stroke, pre-eclampsia, traumatic brain injury and dementia. Having non-invasive, real-time measure of neurovascular function which can predict clinical outcome in the early phases of brain injury will have significant implications on clinical trials and therapeutic targets designed for the treatment and prevention of these various acute and chronic neurovascular injuries.
