In my previous blog post, I dealt in detail about the context of Personality Disorders as defined by Dr. Ruthie O. Grant in her book “People To Be Aware Of: 201 Ways To Identify Toxic People And How To Deal With Them”. Now, I will discuss the three (3) most troublesome Personal Disorders among Toxic Persons that cause the most chaos in relationships as defined by the American Psychiatric Association (APA):

1. Narcissistic Personality Disorder (NPD)

The Narcissistic Personality Disorder (NPD), the book author continued, can be recognized by a “grandiose sense of self-importance; recurrent fantasies of unlimited success, power, brilliance, beauty or ideal love; a craving for constant attention and admiration; feelings of rage, humiliation, or haughty indifference when criticized or defeated; and at least two of the following: a sense of entitlement; exploitiveness, the tendency to take advantage of others and to disregard their rights; oscillation between extreme over empathy, meaning not just inability to see that others have feelings at all.”

2. Borderline Personality Disorder (BPD)

Borderline Personality Disorder (BPD) is defined as “a pervasive pattern of instability of interpersonal relationships, self-image, and effects, and marked impulsivity beginning by early adulthood and present in a variety of contexts as indicated by five (or more) of the following: (1) frantic efforts to avoid real or imagined abandonment; (2) a pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation; (3) identity disturbance: markedly and persistently unstable self-image or sense of self; (4) impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating); (5) recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior; (6) affective instability due to a marked reactivity of mood (e.g. intense episodic dysphoria, irritability, or anxiety usually lasting a few hours and only rarely more than a few days); (7) chronic feelings of emptiness; (8) inappropriate, intense anger or difficulty controlling anger (e.g. frequent displays of temper , constant anger, recurrent physical fights); (9) transient, stress-related paranoid ideation or severe dissociative symptoms.”

3. Anti-Social Personality Disorder (APD)

The APA’s Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV-TR), defines antisocial personality disorder (in Axis II Cluster B):

A) There is a pervasive pattern of disregard for and violation of the rights of others occurring since age 15 years, as indicated by three or more of the following:

(1) failure to conform to social norms with respect to lawful behaviors as indicated by repeatedly performing acts that are grounds for arrest;
(2) deception, as indicated by repeatedly lying, use of aliases, or conning others for personal profit or pleasure;
(3) impulsivity or failure to plan ahead;
(4) irritability and aggressiveness, as indicated by repeated physical fights or assaults;
(5) reckless disregard for safety of self or others;
(6) consistent irresponsibility, as indicated by repeated failure to sustain consistent work behavior or honor financial obligations;
(7) lack of remorse, as indicated by being indifferent to or rationalizing having hurt, mistreated, or stolen from another;

B) The individual is at least age 18 years.

C) There is evidence of conduct disorder with onset before age 15 years.
D) The occurrence of antisocial behavior is not exclusively during the course of schizophrenia or a manic episode.

Final Thoughts

Have you observed any person exhibiting any one or more personality disorders mentioned above? If so, at least you are already aware on the underlying reasons why he or she is such a toxic person that you don’t even want to cross path with him or her.
