Chris Brown Rehab Update: Singer Diagnosed with Bipolar Disorder & PTSD

A recent report from Chris' rehab facility obtained by E! Online shows that the singer actually has Bipolar Disorder and Post Traumatic Stress Disorder, both of which reportedly prompting him to act the way he did.

"Mr. Brown became aggressive and acted out physically due to his untreated mental health disorder, severe sleep deprivation, inappropriate self-medicating and untreated PTSD," E! Online quotes a letter from the singer's Malibu rehab facility.

Chris has been making great improvement in dealing with stress, anger and drugs, says CNN. However, the singer's positive stride does not mean that he will be free from the rehab program anytime soon.

People notes that Chris has committed to the rehab program religiously and is also clocking in ample hours for volunteer work each week but the judge has decided that he should go on with the program as he needs "intense individual, family and medical follow-up over the next year so he can sustain the changes."

"Mr. Brown will also require close supervision by his treating physician in order to ensure his bipolar mental health condition remains stable. It is not uncommon for patients with Post Traumatic Stress Disorder and Bipolar II to use substances to self-medicate their biomedical mood swings and trauma triggers," says the letter obtained by E! Online.

According to CNN, Breezy looked disappointed after knowing he will have to spend two more months at the anger management and drug rehab facility. "He closed his eyes and appeared to meditate for about five minutes while his lawyer, Mark Geragos, met privately with the judge and prosecutor," CNN notes.

Apart from the additional 2-month stay at the Malibu facility, Chris still has 750 hours worth of community labor to go. E! Online says that based from the report from the probation department, the singer has already clocked in 250 hours of community labor with his three-times-a-week schedule, totaling to a weekly 24 hours. At such rate, Chris is expected to complete community labor by October 10, notes E! Online.
