Personality disorders are mental health conditions defined by persistent, rigid and unstable patterns of thinking, emotion and behavior that greatly depart from cultural norms and expectations. The mentioned behaviors can have a significant impact on one’s life, causing pain and limiting their ability to perform well at work, school and in relationships.
A person’s self-image and identity strongly encompass personality disorders, which frequently emerge during adolescence or early adulthood. These disorders can pose challenges in terms of diagnosis and treatment because they are pervasive, and individuals may not realize that their thoughts and actions are detrimental.
Different types of personality disorder
There are 10 personality disorders recognized by the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) of the American Psychiatric Association and are categorized into three clusters based on similar traits. 
- Paranoid Personality Disorder: Characterized by an all-pervasive mistrust and suspicion of others, seeing their intentions as malign even in the absence of proof.
- Schizoid Personality Disorder: People with this disease frequently prefer solitary hobbies and have little interest in establishing intimate connections. Those who suffer from this disorder experience detachment from social interactions and a narrow range of emotional expression.
- Schizotypal Personality Disorder: People with this condition exhibit bizarre conduct, strange thoughts or magical thinking, and have trouble establishing strong relationships. Additionally, individuals with schizotypal personality disorder may exhibit odd speech or perceptual experiences.
Erratic, dramatic, and emotional
- Antisocial Personality Disorder: Individuals with this condition frequently display dishonest and manipulative conduct, impulsivity, a lack of remorse for their acts and disrespect for the rights and feelings of others.
- Borderline Personality Disorder: Unstable relationships, high emotions, impulsivity, and a fear of abandonment are characteristics of this illness. People with borderline personality disorder may experience recurring suicide thoughts or self-harming activities.
- Histrionic Personality Disorder: Individuals with this illness have a great desire for acceptance and may act dramatically or inappropriately to get attention. This disorder involves excessive emotionality and attention-seeking behavior.
- Narcissistic Personality Disorder: This condition manifests a grandiose feeling of self-importance, a desire for praise, and a lack of empathy for others. Those who have it may take advantage of people for their own benefit and struggle to handle criticism.
- Avoidant Personality Disorder: Someone with APD avoids social situations and have trouble building deep connections because of severe social inhibition, inadequacy emotions, and rejection anxiety.
- Dependent Personality Disorder: This condition causes an all-consuming need to be looked after, leading to clingy and humble behavior and a fear of being alone or making decisions alone.
- Obsessive-Compulsive Personality Disorder: People with OCPD exhibit an excessive concentration on orderliness, perfectionism and control. They have strict standards, are overly focused on their job, and have trouble turning over duties.
Causes of personality disorder
The exact causes of personality disorders are not entirely understood, it is believed that a complex interplay between genetic, physiological, psychological, and environmental factors causes these illnesses.
Here are some elements that might support the emergence of personality disorders:
The relationship between genetics and mental health disorders is complex and not fully comprehended but there is a possibility that genetic factors play a role in the development of personality disorders. Personality disorders tend to run in families, according to studies, indicating that genetic factors may play a role in how they develop. 
These studies have found some genetic factors for a number of personality disorders. According to research, these factors contribute between 40 and 60 percent of the variation in borderline and antisocial personality disorders, respectively.
It is important to keep in mind that there are other elements that can contribute to the development of a personality disorder. The interaction between traits and environmental, psychological, and social factors determines a person’s personality and likelihood of having a personality disorder.
Brain structure and function
Personality disorders may emerge due to brain chemistry, structure, or functioning variations. It has been shown that people with borderline personality disorder may differ in the brain regions in charge of controlling their emotions and impulses.
Decision-making, impulse control, and emotional regulation are all executive processes that are mediated by the prefrontal cortex area of the brain. According to research, prefrontal cortex structural and functional abnormalities may contribute to impulsivity, aggression, and emotional instability being worsened in people with borderline and antisocial personality disorders.
Adverse childhood experiences like abuse, neglect, parent loss, or exposure to violence, can raise a person’s chance of developing a personality disorder. In addition to these traumatic events, other childhood experiences also have an impact on the development of various personality disorders.
Inconsistent, overly protective and critical parenting have an effect on a child’s self-esteem, ability to regulate their emotions, and coping mechanisms, perhaps cause the development of a personality disorder.
On the other hand, borderline or narcissistic personality disorder may, however, emerge in children who do not receive their parents’ affection, support, or reinforcement.
The development of personality disorders can be greatly influenced by environmental circumstances. They influence a person’s personality and susceptibility to various illnesses through their interactions with genetic, biochemical and psychological variables. These are some of the main environmental elements that might affect personality disorders:
- Family environment: Personality disorders can arise in families that are dysfunctional and are characterized by conflict, substance misuse, or mental health problems.
- Parenting styles: A child’s self-esteem, ability to control their emotions, and coping mechanisms might be negatively affected by inconsistent, harsh, or excessively protective parenting.
- Socioeconomic factors: Being poor, lacking resources, and living in high-crime or high-stress environments can all increase the risk of developing personality disorders.
- Cultural factors: Cultural norms and values can have an impact on personality and coping mechanisms. Sometimes cultural expectations might cause personality disorders develop.
- Traumatic experiences: Traumatic situations like accidents, war, or natural catastrophes might make people more likely to acquire personality disorders.
- Peer relationships: A person’s sense of self-worth and belonging can be negatively impacted by peer interactions like bullying, exclusion, or peer pressure.
- Psychological factors: An individual’s temperament, coping mechanisms, resilience, and other characteristics of their psychological make-up are all influenced by psychological factors. Some significant psychological factors that may have an impact on the emergence of personality disorders include:
- Temperament: A person may be more likely to develop borderline or antisocial personality disorder if they have a naturally nervous or impulsive disposition.
- Coping skills: Maladaptive cognition and behavior patterns can result from ineffective coping mechanisms such avoidance, denial, or hostility, which are traits of personality disorders. 
- Emotional regulation: Excessive mood swings or heightened sensitivity to unpleasant emotions are emotional regulation problems that can lead to personality disorders.
- Self-esteem: People who have low self-esteem and a negative view of themselves have high risks of developing personality disorders like dependent or avoidant personality disorder because they may feel undeserving of affection and support or fear rejection.
- Early attachment experiences: In instance, personality disorders like borderline or avoidant personality disorder, which are marked by issues with interpersonal connections, may be more likely to develop in children who suffer disturbed attachment or who have emotionally unavailable parents.
- Cognitive distortions: Unhelpful cognitive patterns like catastrophizing, overgeneralizing, or thinking in black-and-white terms can lead to personality disorders.
