Diagnosis for Kony 2012's Russell: Reactive Psychosis

The family of Invisible Children co-founder Jason Russell says his half-naked romp through San Diego was caused by "brief reactive psychosis, an acute state brought on by extreme exhaustion, stress, and dehydration." His wife had earlier said as much, but the new statement claims this is his official "preliminary diagnosis," and reasserts that the incident was not caused by drugs or alcohol. Russell, who created the viral "Kony 2012" video, will stay in the hospital for several weeks, TMZ reports.

The statement adds that, according to doctors, reactive psychosis is "a common experience given the great mental, emotional, and physical shock his body has gone through in these last two weeks." Russell "will get better," although "the recovery process could take months," it concludes. But could "exhaustion, dehydration, and malnutrition" really cause an episode as bizarre as the one Russell had? Slate says no—at least not without some sort of "underlying mental illness."
