I don't think there is any for what he might have. Specifically, I was struck reading the article and your list how perfectly this dude matches Cleckley's _Mask of Sanity_ profiles of psychopaths - no long-term plan, continuous lying and deception of others without any remorse, confabulated explanations, impulse-driven actions, big risks taken for trivial gains, grandiosity, self-inflicted financial problems... The problem being that for personality disorders, there are no cures or treatments (and for psychopathy there's some troubling results that attempts to treat it just made them more dangerous).

If it's psychopathy, well, I would note that they are famous for fooling even people who have read detailed accounts of their personal history. Cleckley is not the only person writing on the topic who notes personal astonishment at how they were manipulated by a patient even after having read the patient's file. If forewarned is not forearmed, I cannot blame Assange or the other Wikileakers too much.
