I'm not sure what you mean by 'dysfunctional' but anyhow...
There are things about H that set him apart from others, memory lapse, constantly disorientated, not being able to sit still (fidgeting), always on the go, exhausted even when not busy, extreme indecisiveness, brilliant (if not genius) in his field of interest. He went for tests for exhaustion but the doc could not find anything.
