Stroke in the young in Israel. Incidence and outcomes.

BACKGROUND AND PURPOSE: Data on stroke in the young in Israel are fragmentary. To obtain an overall perspective and to assess the nature and magnitude of the problem, a study was conducted on stroke occurrence in the young population during 1 year. Incidence and outcomes are reported in this communication.

METHODS

We conducted a prospective ascertainment of first stroke in all permanent residents of Israel aged 17 to 49 years who were referred to all acute-care hospitals in the country or died before reaching them.

RESULTS

We identified 253 first stroke victims in the studied population; 62.8% were male. The age- and sex-adjusted incidence rate for all types of stroke was 10.36/100 000 per year (males, 13.00; females, 7.71). The majority of strokes (80.6%) were cerebral infarctions, with 9.9% intracerebral hemorrhages, 7.9% subarachnoid hemorrhages, and 1.6% strokes of unspecified type. The case-fatality rate for all types of stroke was 9.9% (mortality within the first 4 weeks after the event, on average 6 days). The survival rate was 95% for cerebral infarctions, 64% for intracerebral hemorrhages, and 80% for subarachnoid hemorrhages; 86.7% of all survivors remained with an impairment resulting in a disability.

CONCLUSIONS

Incidence rates were similar to those reported from developed Western countries. The case-fatality rate of 9.9% and the considerable percentage of survivors with a disability in a population at the beginning of their family, professional, and social lives indicate the magnitude of the problem.
