Comparison of stroke features and disability in daily life in patients with ischemic stroke aged 55 to 70 and 71 to 85 years.
OBJECTIVE
This study compared stroke features and poststroke disability in two age groups of patients with ischemic stroke: younger (55 to 70 years) and older (71 to 85 years). Stroke has an impact on daily living in many areas, but whether risk factors, stroke features, and poststroke disability differ between young and old patients with stroke is not so well established.


METHODS
A cohort of 486 ischemic stroke patients aged 55 to 85 years admitted consecutively to the Helsinki University Central Hospital (Finland) between December 1, 1993, and March 31, 1995, were examined 3 months after the index stroke. Structured medical, neurological, and radiological (MRI or CT) examinations, mental status, and emotional examination and interview of a close informant were done. Prestroke and poststroke activities of daily living were assessed with five scales: the Index of ADL, Instrumental Activities of Daily Living Scale, Functional Activities Questionnaire, Blessed Functional Activities Scale, and Barthel Index.


RESULTS
History of cardiac failure (P < .001), atrial fibrillation (P < .001), and cardioembolic stroke (P = .011) was more frequent in the older age group, whereas stroke due to large-artery atherosclerosis (P = .048) was more common in the younger age group. The older patients more often had major dominant stroke syndrome (P = .018). Comparison of activities of daily living before and after stroke showed that the older age group deteriorated significantly more than the younger age group after adjustment for sex, education, and living conditions (Barthel Index, P = .005; other scales, P < .0001).


CONCLUSIONS
The stroke patients in young and old age groups had different risk profiles and stroke features. The older stroke patients were more dependent and disabled beforehand, and after stroke they were relatively even more dependent than the patients in the younger age group. Because older patients already constitute the majority of stroke victims, the importance of early active diagnosis, treatment, rehabilitation, and guidance is stressed.
