The Paradox of Psychopathy

A gray area is the impulsive aggression that can persist after psychotic symptoms have subsided. Conceptually, such aggression can represent incomplete control of schizophrenic symptoms, such as persistent impairment of frontal lobe functions, the impulsive aggression seen in psychopathy, or a third comorbidity such as intermittent explosive disorder. Regardless, it can be difficult to sort out the exact origin in the patient with both schizophrenia and psychopathy.
