How does Borderline Personality Disorder differ from Antisocial Personality Disorder?

Answer

In sharp contrast to Anti-Social Personality Disorder (sociopathy) is another personality disorder, termed Borderline Personality Disorder, in which the problem is the opposite of the problem of the sociopath: the sympathetic nervous system of person with BPD responds too easily, too strongly, and way too often!

Meanwhile, in the true sociopath/psychopath, the fight-or-flight reaction is very brief, extremely difficult to sustain even in an emergency, and does not touch certain organs as it ought to do; sociopaths are chronically "bored" because they are literally half-asleep most of the time. (Even though they tend to look awake and behave in an alert, intense manner.)

Additionally, although individuals with Borderline Personality tend to use manipulation in various forms such as malingering, these are usually intended to gain the concern or sympathy of perceived caregivers. In persons with Antisocial Personality Disorder, deceit and manipulation are used to gain material gratification such as money, gifts, etc. Also, personality features specific to APD, such as an extreme sense of entitlement, egocentricity, narcissism, and exaggerated self-assurance are typically absent in persons with BPD.
