After watching Robert Sapolsky’s video on religion I decided to do some reading up on temporal lobe epilepsy and hypergraphia… I ran across this:
THE Bible may contain the oldest recorded case of temporal lobe epilepsy. Ezekiel, the prophet whose visions are recorded in a book of the Old Testament, apparently had all the classic signs of the condition. [...]
People with the disease experience partial seizures, often accompanied by a dreamy feeling that things are not quite as they should be. Patients are often misdiagnosed with psychiatric problems. Neurologically, Ezekiel displayed some obvious signs of epilepsy, such as frequent fainting spells and episodes of not being able to speak.
The Biblical figure, who chronicled the fall of Jerusalem in 586 BC, exhibited other peculiarities associated with the disease. For instance, he wrote compulsively, a trait known as hypergraphia. Altschuler points out that the Book of Ezekiel is the fourth longest in the Bible-only slightly shorter than Genesis. “It’s impenetrable,” he says. “He goes on and on.”
Ezekiel was also extremely religious, another characteristic associated with this form of epilepsy. While many Biblical figures are pious, none was as aggressively religious as Ezekiel, says Altschuler. (via.)
