Abstract
Julius Caesar (100-44 BC) was one of the most charismatic political figures in history. Best remembered for his military achievements, he was also a writer, historian, and statesman. Through his constitutional reforms, he played an important role in the events that led to the end of the Roman Republic and the birth of the Roman Empire. Historical sources reveal that Julius Caesar suffered from headaches, seizures, and personality changes. In this essay, we highlight the life of Julius Caesar, with emphasis on the potential origin of his sickness. Although a definitive diagnosis obviously cannot be made, as new published studies showed a possible cerebrovascular etiology, a new hypothetical diagnosis is presented.
