Depression May Increase Risk of Stroke
September 23, 2011
Many people become depressed after they experience a stroke, but new research shows that depression may actually increase risk of stroke and of dying from that stroke.
"We didn't know whether depression, per se, could increase the risk of stroke, but now we have conclusive and compelling evidence that it can," says study researcher An Pan, PhD, research scientist at the Harvard School of Public Health in Boston.
The new findings should serve as a call to action to diagnose and treat depression, experts tell WebMD.
"Depression affects quality of life, heart disease, and stroke risk," says Ralph Sacco, MD. He is chair of neurology at the University of Miami Miller School of Medicine and the immediate past president of the American Heart Association.
"Depression is prevalent and is probably underdetected and undertreated. So this is another reason to think about monitoring people for depression and getting them the proper treatment," he says. Sacco was not involved in the new study.
The new analysis included 28 studies of more than 300,000 people. During a follow-up period that ranged for two to 29 years, there were 8,478 strokes. Depressed people turned out to be 45% more likely to experience any type of stroke than those who were not depressed. They were also at a 55% increased risk for dying from that stroke.
The new findings appear in the Journal of the American Medical Association.
