It is likely that Caligula suffered from epilepsy that began in childhood, perhaps with febrile seizures, and later dialeptic or cognitive. In 37, Caligula experienced a state of epilepticus that triggered an epileptic psychosis followed by psychopathic and paranoid changes. This clinical condition could also be influenced by excessive alcohol consumption and lead poisoning.
