Age and cerebral infarction: a postmortem study of 77 cases of cerebral infarcts in the middle cerebral artery territory.

Adverse effect of age on ischemic stroke short-term mortality was reported in some studies and attributed either to more frequent extracerebral causes of death or to an increased severity of ischemia in the aged brain. Relationship between age, size of infarcts, and causes of death were studied in 77 consecutive patients who died from infarction in the middle cerebral artery territory. Area of infarcts was assessed by planimetry, and results were expressed as an index of infarcted area. No significant relationship was found between age and the size of infarcts, the cause of death, or the interval from stroke to death. These results do not support the hypothesis of an increased severity of ischemia in the aged brain.
