If young Anakin Skywalker had gotten himself into see a good psychotherapist, he might have steered clear of the dark side and the Darth Vader get-up. The Star Wars prequels show that Anakin suffered from borderline personality disorder, say French psychiatrists. (They've made the argument before, but will buttress it in an upcoming issue of Psychiatry Research.)
Anakin hits six of nine marks for the disorder, including issues with anger management, impulsive behavior, abandonment, and attempting to disassociate himself with unpleasant events, explains LiveScience. Adds one of the researchers: "Using the dark side of the Force could be considered as similar to drug use: It feels really good when you use it, it alters your consciousness and you know you shouldn’t do it."
