- Abstract
- Background
The risk profiles and stroke presentations may differ between elderly stroke patients and their younger
counterparts. The most appropriate stroke-management regime for a better outcome can only be achieved with
knowledge of the characteristics of elderly stroke patients. This study compared the clinical and radiological
characteristics of elderly (≥80 years) ischemic stroke patients with those aged <80 years.
Methods
Consecutive acute ischemic stroke patients were enrolled. The following parameters were obtained for each
patient: clinical variables [i.e., risk factors, initial National Institutes of Health Stroke Scale (NIHSS) score, mode of onset,
in-hospital complications, and modified Rankin scale (mRS) score at 3?months], radiological variables, and
clinicoradiological discrepancies.
Results
Of the 436 enrolled patients, 60 (13.8%) were elderly. The proportion of men was lower among the elderly than
among those patients aged >80?years (40.0% vs. 63.3%; p=0.001), while their initial NIHSS score was higher (median, 4 vs.
3; p=0.033). Furthermore, an unclear stroke onset (46.4% vs. 32.8%; p=0.049) and clinicoradiological discrepancies (13.8%
vs. 5.7%; p=0.044) were more common among the elderly. The proportions of subjects with stroke of undetermined cause
(30.0% vs. 18.0%; p=0.019) and multiple circulation infarctions (23.3% vs. 12.6%, p=0.030) were higher among the elderly.
A favorable outcome (mRS score of 0 or 1) was more common in the younger stroke patients (57.5% vs. 25.9%, p<0.0001).
Multivariate analysis revealed that younger age, male gender, and initial stroke severity were significantly associated
with a favorable outcome.
Conclusions
These results indicate that stroke presentation in the elderly differs from that of their younger counterparts
in terms of clinical and radiological variables.Key Words: Ischemic stroke, Elderly, Clinical outcome, Diffusion-weighted imaging
