Abstract
Background: 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. Aim: 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. Material and Methods: Review of a database
of a population study on the incidence, 30-day case fatality rate, and prognosis
of stroke performed in a northern Chilean city between 2000 and 2002. Results:
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. Partial
anterior circulation infarction was the most common stroke location in 61%.
Conclusions: Twenty percent of patients with a first episode of ischemic stroke
have aphasia.
