Stroke survivors may have a higher risk of developing depression or another mood disorder within the first year, according to new research that compared their risk to the general public as well as people who survived a heart attack.
Past research shows depression is common after stroke, affecting nearly one-third of survivors. For the new study, researchers wanted to dig deeper and see how stroke impacts other mental disorders.
The study, published in the American Heart Association journal Stroke, focused on 86,111 people in Danish hospitals from 2004 to 2018 with no history of mental health disorders who had a stroke.
It found that stroke survivors had a 15% risk of developing a mood disorder, primarily depression, within the first year. This risk corresponded to an approximately 2.3-fold increased risk compared with matched individuals from the Danish general population. Stroke survivors also had an increased risk for other mental health problems, including substance abuse disorders and stress and anxiety disorders, as well as brain disorders such as dementia. But these conditions were less common.
