The incidence of TIAs increases with age, from 1-3 cases per 100,000 in those younger than 35 years to as many as 1500 cases per 100,000 in those older than 85 years. [9] Fewer than 3% of all major cerebral infarcts occur in children. Pediatric strokes often can have quite different etiologies from those of adult strokes and tend to occur with less frequency.
