Chris Brown's publicist says the singer has suffered a seizure brought on by intense fatigue and extreme emotional stress.
Publicist Nicole Perna says the "Look At Me Now" singer suffered a non-epileptic seizure early Friday morning while he was working in a Los Angeles studio.
A doctor examined the 24-year-old but he wasn't hospitalized.
Perna says what she referred to as the "continued onslaught of unfounded legal matters and the nonstop negativity" contributed to Brown's illness.
The singer has been on felony probation since the 2009 beating of then-girlfriend Rihanna.
A judge revoked his probation last month and ordered a hearing in a May 12 hit-and-run case.
In February, authorities investigated a fight between Brown and singer Frank Ocean at a recording studio, but Ocean didn't press charges.
