That is one of the theories. The other theory is tied to the function of dopamine. Dopamine inhibits another chemical called GABA. Without any GABA dopamine doesn't really do anything. The other theory is that they have normal levels of Dopamine and low levels of GABA. These theories came about by the observation that anti-dopamine drugs help the symptoms. The simple answer is we're not quite sure yet.

Tonic dopamine activity in the brain's reward system is a steady, baseline level of dopamine release, while phasic dopamine activity is a rapid and transient increase in dopamine release in response to rewarding stimuli.
