If your patients have risk factors for stroke, particularly high blood pressure, you need to assess them carefully for cognitive issues, a new study suggests. High blood pressure and other known risk factors for stroke increase the risk of developing cognitive problems, even among people who have never had a stroke, the REasons for Geographic and Racial Differences in Stroke (REGARDS) study funded by the National Institutes of Health has found. "Individuals at risk for stroke may experience cognitive problems as their blood vessels deteriorate," explains the study that included 24,000 participants over an average of 4.1 years.
