Hereditary predisposal of this condition is unquestionable as well as the presence of noradrenergic and dopaminergic dysfunction in the pré-frontal cortex and connections. Notwithstanding this condition diagnosis is based on clinical data. Morbid associations occur in approximately half of the individuals and the prevailing comorbidities as of psychiatric nature. The presence of co-morbidity may modify the therapy and prognosis.
