The Emperor Dom Pedro II: his convulsive seizures when a boy.

INTRODUCTION Dom Pedro II, the Prince Heir and Emperor under regency, in a delicate period of the construction of the Brazilian nation, had convulsive seizures. OBJECTIVE To investigate the convulsive seizures and related syndromes of Dom Pedro II and his family, besides the physicians in charge of the health care. METHOD Narrative review based on primary and secondary sources. CONCLUSION The scattered and self-limited convulsive seizures associated with physical and mental integrity favored a benign prognosis. Dom Pedro and his family presented rich history of epileptic seizures and febrile convulsion. This variety resembles the diagnosis of generalized epilepsy with febrile seizures plus that seems to be a combination of several syndromes with shared genetic susceptibility.
