May 21, 2007 -- Anakin Skywalker, the Star Wars character who became Darth Vader, had borderline personality disorder, psychiatrists report.

The news comes not from a galaxy far, far away, but from San Diego, where the American Psychiatric Association (APA) is holding its 160th annual meeting.

Today, experts from the psychiatric department at France's University Hospital of Toulouse told the APA's annual meeting that Anakin Skywalker/Darth Vader could "clearly" be diagnosed with borderline personality disorder.

Borderline personality disorder is a serious mental illness marked by instability in moods, interpersonal relationships, self-image, and behavior, according to background information on the web site of the National Institute of Mental Health (NIMH).

The French psychiatrists -- who included Laurent Schmitt, MD -- based their diagnosis on original Star Wars film scripts.
