According to new court documents, one of the factors contributing to Chris Brown's frequent violent run-ins with the law and fellow celebrities, like Drake and Frank Ocean, is mental illness.

On Friday, it was revealed that the pop star has been diagnosed with bipolar disorder, severe insomnia and Post Traumatic Stress Disorder, which reportedly triggered his anger issues.

The news was revealed during the progress hearing for his 2009 assault against Rihanna, according Los Angeles Superior Court documents obtained by E! News. The documents, which were filed by the facility where Chris recently completed 90 days of anger management therapy, attributed Brown's "mood swings" to PTSD and bipolar disorder.

"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," a letter from the facility read, according to MTV. "Mr. Brown became aggressive and acted out physically due to his untreated mental health disorder, severe sleep deprivation, inappropriate self-medicating and untreated PTSD."

The documents also state that Superior Court Judge James R. Brandlin said, "It is evident that [Brown] has responded well to the dual diagnosis treatment." Representatives from the rehab facility added that he has been "beyond exemplary" in fulfilling his community service requirements.

Brown was ordered to spend an additional two months at the Malibu rehab facility during Friday's hearing, NY Daily News reports.

Last month, a 20-year-old man who alleges that he was punched by the singer and his bodyguard last October, filed a civil lawsuit seeking $1.5 million from each man.

Parker Isaac Adams filed the suit in Superior Court in Washington for medical expenses he claims he incurred during a physical altercation outside a Washington hotel last year. The lawsuit states that Adams suffered from a fractured nose and injuries to his head and face as a result of being punched, reports the Associated Press.

Adams told CBS News that he is seeking to recover money for his medical bills, which include visits to a plastic surgeon and a breathing specialist.
