This chapter applies current neurological research on epilepsy to make the case that Muhammad likely was afflicted with the condition. Using contemporary medical discussions of seizures, I identified instances in the hadiths where Muhammad probably manifested epileptic symptoms. They involved apparent absence seizures, focal seizures: visual and auditory auras, motor seizures, forced thinking and forced acts, fear, and suicidal ideation. It concludes with a discussion of neurotheology, which uses neurobiology to analyze religious origins, theological beliefs, and spiritual experiences.
