From TMZ:
The L.A. City Fire Dept. rushed to a Hollywood recording studio early Friday morning, after getting a 911 call that Chris Brown had a seizure … TMZ has learned.
The call came from Record Plant recording studios in Hollywood at 1:09 AM. When EMTs arrived … we’re told Chris refused treatment and also refused to be transported to the hospital.
We do not know if it was indeed a seizure, but we’ve learned Chris did suffer from seizures as a child.
