People with OCD are THREE TIMES more likely suffer a stroke than those without the mental health condition, study finds A new study looked at 50,000 patients in Taiwan, more than 28,000 of whom were diagnosed with obsessive compulsive disorder (OCD) OCD patients were three times more likely to suffer a stroke than patients without the mental health conditions Middle-age adults with OCD were 2.6 times as likely and those aged 60 and older were nearly 3.5 times as likely Researchers say they don't know why there is a link, but suspect people with OCD have other conditions that raise their risk such as high blood pressure
