Patients with a previous history of psychosis or cognitive impairment were excluded. They and\/or their caregivers answered a structured hallucination and sleep questionnaire at admission, within the first 15 days and at the clinical follow\u2010up 3\u20136 months after discharge. Lesion location (IMAIOS online atlas) and leukoaraiosis (Wahlund scale) were determined by magnetic resonance imaging or computed tomography scan.

The appearance of hallucinations was not influenced by age, sex, neuropsychological performance during admission or modified Rankin scale score at discharge. Visual hallucinations were associated with occipital cortex lesions (<jats:italic>P<\/jats:italic> = 0.04), and with sleep disturbances during and before admission (<jats:italic>P<\/jats:italic> = 0.041 and <jats:italic>P<\/jats:italic> = 0.03 respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Visual hallucinations are relatively frequent in patients with acute stroke and they are self\u2010limited.
