What causes personality disorders ?

Personality Disorders usually begin in late teens or adulthood. It is not fully understood what causes personality disorders but it is believed that these factors may contribute to the development of personality disorders.

Childhood Traumas

One study has found a link between childhood traumas and development of personality disorders. For instance, people with borderline personality disorder had especially high rates of childhood sexual abuse, or other forms of childhood traumas.

Poor Parenting During Childhood

Studies have consistently found a link between poor parenting practices and poor parent child interactions. For example, if a child had never been taught boundaries or discipline, and he/she gets whatever he/she demands for, the child is likely to grow up feeling very entitled and may develop into narcissistic personality.  

Genetics

Although this factor needs to be researched better, studies have identified a malfunctioning gene that is a contributing factor for obsessive-compulsive disorder, and genetics are linked to aggression in some people with personality disorders.
