    BACKGROUND AND PURPOSE: Although N-methyl-D-aspartate (NMDA) antagonism may be a useful therapeutic approach in stroke treatment, it has been found that these pharmacological agents cause neuronal necrosis in restricted cortical regions of the rodent brain. METHODS: To test the hypothesis that age and sex influence NMDA antagonist-induced neuronal necrosis, male and female rats were studied at 2 months (young), 12 months (middle-aged), and 24 months (old) of age. A dose of 5 mg/kg MK-801 was administered, followed by quantitation of neuronal necrosis at nine coronal levels in the cingulate and retrosplenial cortex at 1 week of survival. RESULTS: Mortality was dependent on age but not sex and was higher in the old rats (P
