Brain Health Research

Emerging evidence shows that treating vascular disease and vascular risk factors can reduce cognitive and functional decline. Stroke and cognition researchers at PHRI are conducting, and collaborating in, international work on dementia and vascular disease.

A leader in stroke research for decades – including our landmark study, INTERSTROKE, which identified the 10 greatest risk factors responsible for 90% of strokes globally – PHRI’s high-impact work in this area includes the development of an optimal cognitive test for international clinical trials, and collaboration in the first large stroke registry in a developing country (India).
