Infections and suicide

Findings suggest that infections might be linked to the development of psychiatric disorders and suicidal behaviour. To estimate the association between hospitalization with infection and the risk of death by suicide. An increased risk of death by suicide was found among individuals hospitalized with infection in prospective and dose-response relationships. These findings indicate that infections may have a relevant role in the pathophysiological mechanisms of suicidal behaviour.
The study was published in JAMA Psychiatry.
The project has received support from the Lundbeck Foundation.
