The proportion of elderly people in China is projected to increase rapidly but there is limited information on status epilepticus (SE) in this population. We evaluated retrospectively the etiology, response to treatment, outcome and predictors of mortality in a group of elderly patients with generalized tonic-clonic SE in Hong Kong, China. Factors for increased mortality were analyzed using a logistic regression model. Of the 80 acute admissions for SE from two large urban hospitals over a seven-year period, 1996-2002, the two leading causes were attributed to cerebral infarct (n=28, 35%) and cerebral haemorrhage (n=14, 17.5%). The mean age was 74.2 years (range 60-93 years). At six months from the onset of seizures, 26 patients (32.5%) had made a good recovery but another 28 (35%) had died. Results showed that mortality was associated with increasing age (OR 1.08, 95% CI 1.01-1.16) and SE due to an acute symptomatic disturbance (OR 4.90, 95% CI 1.17-13.67). SE is associated with significant morbidity and mortality in this age group.
