Epileptic seizures in a descendant of Dom Pedro I.

UNLABELLED Intrauterine seizure is a rare event. Genetic predisposition and trauma are possible risk factors. OBJECTIVE To review and comment on the historical description of intrauterine events of a bastard daughter of Dom Pedro I (Maria Isabel Alcântara Brasileira - 1830-1896). METHOD Review of historical facts about the health of Dom Pedro I's daughter according to primary and secondary historical data. RESULTS According to historical accounts, Dom Pedro I's daughter suffered trauma during the intrauterine period that provoked intrauterine seizures. At the age of eight years, she developed self-limited and benign generalized epilepsy. Like her father, she had mood problems and also learning difficulties. CONCLUSION Dona Maria Isabel's own report does not shown sufficient evidence to support the diagnosis of post-traumatic intrauterine seizures. Nevertheless, her family history suggests a genetic basis for her epilepsy.
