Summary Objective To explore the influence of several estimates of family socioeconomic status on the long‐term clinical course and social outcomes of children with epilepsy. Methods The Nova Scotia childhood epilepsy cohort is population based and includes all children in this Canadian province who developed epilepsy between 1977 and 1985. Eligible patients had ≥10 years of follow‐up. Children with childhood absence epilepsy were excluded. Total family income at seizure onset was assessed at seizure onset and classified as “poor” (first quintile), “adequate” (second to third quintiles), and “well‐off” (fourth to fifth quintiles). We also assessed parental education and home ownership. Social outcome was assessed in those with normal intelligence who were ≥18 years of age at the end of follow‐up using a semistructured interview that explored eight adverse effects. Results Of 584 patients, 421 (72%) were included. Average follow‐up was 26 ± 5.6 years. Overall 137 families (33%) had “poor” income, 159 (38%) had “adequate income,” and 125 (30%) were “well‐off.” Terminal remission of epilepsy occurred in 65% of the poor, 61% of the adequate, and 61% of the well‐off (p = ns). Intractable epilepsy, status epilepticus, number of antiepileptic drugs ( AED s) used, and the number of generalized tonic–clonic or focal with secondary generalization seizures through the clinical course was the same in all groups. Home ownership did not predict remission. Neither paternal nor maternal education was associated with remission. Poor children had significantly more adverse social outcomes including failure to graduate from high school, unemployment, personal poverty, inadvertent pregnancy, and psychiatric diagnoses. Significance In Nova Scotia with universal health care, coming from a poor or more affluent family does not seem to affect the clinical course or long‐term seizure outcome of childhood epilepsy. Unfortunately children from poor families are less likely to have a good social outcome.
