Growing international scientific evidence has indicated a positive effect of SSRI treatment (serotonin reuptake inhibitors) after stroke, beyond its antidepressant effect. We wish to conduct a prospective randomised double blind placebo-controlled multicenter study of the combined neuroprotective and antithrombotic effects of SSRI treatment after stroke. Deletion of the SERT (serotonin transporter) gene may influence this treatment effect and may in itself be a risk factor for stroke, an aspect we also wish to explore.
