Sequelae after a stroke are common and may lead to disability. Aphasia - defined as an acquired language disturbance - can cause important limitations in quality of life. To describe the epidemiological features of patients who had an aphasia after a first episode of ischemic stroke and their functional outcome at six months.

Aphasia was diagnosed in 28 of 142 patients in whom the disorder was sought (20%). The projected incidence rate in the city where the study was carried out is 7.06 per 100,000 inhabitants. The mean age of these 28 patients was 66 ± 20 years and 53% were women. The main risk factor for stroke was hypertension in 62%. The etiology of stroke was undetermined in 64% of these patients.
