Stroke is a disorder that has great prevalence, defined vascular territories and psychiatric signs generally emerge in association with specific cognitive deficits.

Dementia occurs frecquently after acute ischemic stroke. The incidence of dementia six months after stroke is about 42%. Fortunately, in recent years, more attention has been paid to organic disorders provoked by strokes, especially to dementia.

To follow up the occuring dementia after stroke and also to follow the various psychiatric disorders with the onset during or after an acute ischemic stroke.

Altogether 110 patients were recruited to this observational and non-interventional study, patients who were suffering from a psychiatric disorder after an ischemic stroke (according to DSM IV TR). The screening was followed by four visits during six months, when CGI, 17-HAMD, CROCQ and MMSE scales were used.

Of 110 patients, 39,09% has been diagnosed with dementia. A number of these patients (n = 26) developed an onset like paroxistic disorder (60,46%), or an acute syndrom (20,93%) and 8 patients were considered “de novo” (with the onset of cognitive impairement after 60 days). There were various acute disorders occuring in the onset of dementia, that includes: amnestic syndrom, organic delirium, organic anxiety syndrom and a small number of patients (n=2) who developed mild cognitive disorder.

The literature considers vascular dementia occuring after an ischemic stroke and increasing step by step mnestic deficits; our study releaved a metamorphosis of various types of onset (anxiety, depression, delirium) or cognitive impairement could occurs after 30 days.
