PRESENTATION, CLINICAL COURSE, AND OUTCOME OF CHILDHOOD STROKE

We reviewed the presentations, clinical courses, and outcomes of 42 children with unilateral hemispheric stroke. Infants with strokes identified within the first few days of life usually presented with seizures. These infants had few abnormal neurologic findings as neonates, but hemiparesis became evident as gross motor development proceeded. Infants with strokes identified later in the first year of life usually presented with pathologic early hand preference without a history of an ictus. During subsequent development, the motor deficits in these children became more evident, producing an apparent progression of the neurologic abnormalities. Strokes identified in older children typically presented as sudden hemiparesis, often associated with seizures. The hemiparesis in these children was most severe at the onset, followed by some improvement in strength in all patients. Functional outcome was variable. At last follow-up, all children were ambulatory, some with clinically apparent hemiparesis. Eight of the 42 children (19%) developed recurrent seizures with an onset ranging from 4 months to more than 10 years (median: 26 months) after the stroke.
