Could you tell me what is organic personality disorder?

Trauma caused BPD: Opd was a traditional diagnostic category used to account for personality disturbances after traumatic brain injury (tbi). Recent dsm axis-ii personality disorders, notably borderline personality disorder (bpd) has largely replaced it but the cause is thus lost and some think it is important. So, the effects are similar - on/off in mood, relationships, behaviors - difficult for themself and others.

OPD: Personality disorders presenting with symptoms of the disorder, plus some organic or physical factors have been identified as possible cause of the symptoms or attributed to them.
