Research carried out at Sahlgrenska University Hospital in Gothenburg on 401 stroke-free 85-year-olds found there is a connection between depression and increased risk of suffering from a first stroke, reports the Reuters news agency.
Of the patients, who were studied over a three-year period, 18 percent suffered from depression when the study began.
Analysis has showed that these patients had nearly a three times greater risk for suffering a stroke during the time the study was conducted.
The study, which is published in the magazine Stroke, also showed a connection between high blood pressure and stroke.
