Chris Brown, Grammy-winning recording artist and source of much controversy, suffered a non-epileptic seizure Friday at the Hollywood recording studio Record Plant, according to Brown’s rep.

Around 1 a.m., the Los Angeles city Fire Department responded to a 9-1-1 call that the 24-year-old R&B star had suffered a seizure, reports the Los Angeles Times. While Brown was never hospitalized, the doctor tending to him said the seizure likely resulted from the artist’s draining battle in and out of court.

“His doctor tended to him this afternoon and attributes the NES to intense fatigue and extreme emotional stress, both due to the continued onslaught of unfounded legal matters and the nonstop negativity,” his rep said in a statement.

Non-epileptic seizures (NES) differ from epileptic seizures in that they’re not of physical origin, but of psychological origin. They present significant challenges to diagnose, as the symptoms for both appear similar. In one study, according to the Epilepsy Foundation, “fully 25 percent of patients referred to an epilepsy center to be evaluated for surgery had non-epileptic seizures.”

The main differences, while slight to the naked eye, are stark when read on electroencephelograph (EEG). Epileptic seizures will read erratically while NES will display normal brain function. What’s more, NES only occurs when the person is awake, although they can last much longer than epileptic seizures.

Brown’s nonstop negativity and extreme emotional stress come on the heels of ongoing legal matters that include a hit-and-run charge and driving without a license or insurance.

This past May, Brown rear-ended a Mercedes Benz but adamantly refused to provide his driver’s license or insurance, which classified the crime as a hit-and-run, according to a Los Angeles city attorney. Though he turned himself in on August 6, he was promptly released 40 minutes later with no bail.

According to the Epilepsy Foundation, Brown can minimize his risk for future NES with the successful implementation of psychological counseling, or even psychiatric medication.
