Machado de Assis' Original Sin.

Machado de Assis (1839-1908) suffered from temporal lobe epilepsy, probably with origin in the non-dominant hemisphere. The evidence for this is provided by the detailed reports of the characteristics of his seizures by his contemporaries and by his correspondence with other writers. He was treated with bromides and homeopathy. It is unclear whether his neurological disorder influenced his artistic performance. What is evident is that he was deeply ashamed of the disease - he avoided the word "epilepsy" and just wrote about it in his personal correspondence with friends in the last years of his life. Though controversial, he had no clear traces of personality disorders linked to his temporal lobe epilepsy. Despite all his adversities, including being "mulatto," having a stutter, being of humble origins, and epileptic in a period when there was no efficacious therapy and a profound stigma associated with the disease, Machado de Assis became one of the most important Brazilian writers of all times.
