There are some psychological disorders that possibly could result in a PPD. Posttraumatic stress disorder, organic brain syndrome (closed head injury with documented damage), and some pain disorders.
Mood disorders (e.g. major depressive disorder) and other anxiety disorders (e.g. generalized anxiety disorders) are not likely to be permanent conditions. Bipolar disorder (_manic depressive disorder_) and schizophrenia do not result from injury.
Personality Disorders (the subject of next year_s [2004-2005] seminar) cannot result from injury nor can learning disorders.
Unfortunately, with the high rate of prescribing narcotics after injury, some addictive disorders can result in a PPD.
Since PPD often referred to in terms of _disability of whole person,_ psychological PPD ratings, when they occur, are typically low.
