An analysis of 17 different depression and stroke studies led researchers this week to propose a link between the psychological disorder and an increased risk of stroke.
At this time researchers involved in the analysis are not sure in stroke risks are linked directly to depression or if they share an underlying cause.
A second study conducted by Dr. Li-Qiang Qin at Soochow University in China recently also compiled information from 17 studies and more than 200,000 participants and then looked for depression and stroke symptoms in patients, they then compared those individuals with patients who did not demonstrate signs of a mood disorder.
The long-term study examined people who had not yet had a stroke and then followed them over a period of three to 29 years.
In two of the compiled studies researchers found that depression lowered the risk of a stroke, while two study’s found no difference between depression and non-depression patients. However in the remaining 13 studies people with depression were shown to have a higher risk of stroke. When all 17 studies were combined the risk of stroke increased by 34 percent for patients with depression.
With 26 out of every 10,000 people in America suffering a stroke each year (800,000 Americans) strokes are the third leading cause of death in the United States according to the Centers for Disease Control and Prevention.
Furthering the study’s validity was another research project earlier in the year which polled together 28 projects while also finding that an increase in stroke occurred when depression was present.
