Stroke: associations with age, sex, and side of weakness.
This study on patients who had strokes investigates the relevance of a patient's age, sex, and the side of any symptoms in association with prestroke status, initial signs, initial disability, and recovery during the first six months. Disability was assessed using the Barthel activities of daily living (ADL) index; non-ADL (social) activities were measured using the Frenchay activities index. Data were collected from 976 patients registered in a community study, and were analyzed statistically using Chi square test, correlation coefficients (for age), analysis of covariance, and two-way analysis of variance. The 469 patients aged 75 years or older included more women (308; p less than 0.001), more who lived alone (147; p less than 0.001), and fewer patients with no prestroke disability (247; p less than 0.001). In this group, the 265 patients who were seen within one week of stroke had a more severe initial disability (p less than 0.001), but not a more severe paralysis. More patients from this age group died (268; p less than 0.001) and more survivors required long-term care. Further analysis showed that older patients made a less good recovery, even after allowing for the correlation between early and six-month Barthel scores (r = +0.41; p less than 0.01). Age had an inverse correlation with level of non-ADL activities at six months (r = -0.365; p less than 0.001). Young women had more severe initial disability (p less than 0.001), but other associations with sex reflected the preponderance of women in the the older age groups.(ABSTRACT TRUNCATED AT 250 WORDS)
