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.
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.
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%.
Twenty percent of patients with a first episode of ischemic stroke have aphasia.
中风后遗症很常见，可能导致残疾。失语症——被定义为后天性语言障碍——会对生活质量造成严重限制。
描述首次缺血性中风发作后出现失语症患者的流行病学特征及其六个月时的功能结局。
回顾2000年至2002年在智利北部一个城市进行的关于中风发病率、30天病死率和预后的人群研究数据库。
在142例被检查出患有该疾病的患者中，有28例被诊断为失语症（20%）。在开展研究的城市中，预计发病率为每10万居民中有7.06例。这28例患者的平均年龄为66±20岁，53%为女性。中风的主要危险因素是高血压，占62%。这些患者中有64%的中风病因未明确。部分前循环梗死是最常见的中风部位，占61%。
首次缺血性中风发作的患者中有20%患有失语症。
