Abstract
OBJECTIVE
To investigate the changes of causes, clinical features, and functional outcomes in childhood strokes. METHOD: This study included 152 patients, aged from 1 to 18 years, who were diagnosed with stroke and admitted to a tertiary hospital between January 2000 and April 2004. All medical records and neurologic images of the patients were reviewed. A parental questionnaire was used to investigate patients' functional outcomes. These results were compared with those of the previous study performed in the same hospital in 2001.
RESULTS
The number of hemorrhagic stroke was 78 (51.3%) and that of ischemic stroke was 74 (48.7%). When compared to the previous study, the incidence of hemorrhagic stroke especially above the age of 10 years decreased and that of ischemic stroke below the age of 10 years increased. The causes of stroke were arteriovenous malformation (AVM, 42.8%), Moyamoya disease (37.5%), vasculitis (5.3%), cardiac disease (3.9%), hematologic disease (2.0%), and undetermined (8.5%). Common clinical features were headache (53.8%), vomiting (43.6%) and loss of consciousness (28.2%) in the hemorrhagic stroke, and hemiparesis (94.6%), headache (35.1%) and speech disorder (31.1%) in the ischemic stroke. 86.0% of the hemorrhagic and 64.8% of the ischemic stroke patients were categorized in the 'good' outcome group.
CONCLUSION
The incidence of ischemic stroke increased to the similar level of hemorrhagic stroke. The most common causes were AVM in the hemorrhagic and Moyamoya disease in the ischemic stroke. Most of these patients showed good functional outcome, regardless of the causes of stroke.
