Research Activities

Dr. Dowlatshahi clinical research achievements are as follows:

1) Identifying and measuring ongoing bleeding in acute cerebral hemorrhage. This work led to several publications and a Heart & Stroke Foundation of Canada grant, a 3-year renewal of the grant, and a Heart & Stroke New Investigator award.

2) Defining the minimal clinically important difference for hematoma expansion. This ongoing work has already led to a landmark publication (Neurology 2011) is cited 45 times (Aug 2014) and used for sample size calculations for several clinical trials.

3) Clinician Scientist-Research Chair Award, New Investigator. This inaugural $750K Dept of Medicine award is awarded to the most productive clinician-scientist who is within their first 5-years of appointment for his research in stroke, hemorrhage and anticoagulation.
