May be caused by lack of prefrontal lobe development during a critical period. Impairment in the ability to form positive relationships. Tendency to engage in behaviours violating basic norms and values. Poor impulse control; little tolerance for frustration; easily bored; risk takers with little concern for danger. Although there is overlap, a diagnosis of apd is not the same as a diagnosis of psychopathy (ie. being a psychopath) Although psychopathy is a meaningful construct for many psychologists, it is not even a dsm diagnostic category.
