Personality Disorders


Personality disorders are a group of mental health conditions that are characterized by long-term patterns of thoughts, feelings, and behaviors that deviate from cultural and societal norms and cause significant distress and impairment in daily life. These patterns are inflexible and stable, and usually begin in adolescence or early adulthood.


There are several different types of personality disorders, including:

  • Paranoid Personality Disorder: characterized by a persistent distrust and suspicion of others, even without reason.
  • Schizoid Personality Disorder: characterized by a lack of interest in social relationships, and a preference for being alone.
  • Schizotypal Personality Disorder: characterized by odd or eccentric behavior, difficulty in social relationships, and distorted thinking.
  • Antisocial Personality Disorder: characterized by a disregard for the rights of others, a tendency to lie and manipulate, and a lack of empathy or remorse.
  • Borderline Personality Disorder: characterized by intense and unstable relationships, difficulty in regulating emotions and impulses, and a fear of abandonment.
  • Histrionic Personality Disorder: characterized by excessive emotionality and attention-seeking behavior.
  • Narcissistic Personality Disorder: characterized by a sense of grandiosity, a need for admiration, and a lack of empathy for others.
  • Avoidant Personality Disorder: characterized by a fear of rejection and social interaction, and feeling inadequate and sensitive to criticism.
  • Dependent Personality Disorder: characterized by a need to be taken care of and a fear of separation.


The exact causes of personality disorders are not fully understood, but research suggests that a combination of genetic, biological, and environmental factors may play a role.


Some common causes of personality disorders include:

  • Genetics: Studies suggest that certain genes may make a person more susceptible to developing a personality disorder.
  • Brain chemistry: Imbalances in certain chemicals in the brain, such as neurotransmitters, may contribute to the development of personality disorders.
  • Environmental factors: Trauma, stress, and major life changes during childhood and adolescence can increase the risk of developing a personality disorder.
  • Family dynamics: Growing up in a home where emotional, physical, or sexual abuse is present, or where there is a lack of emotional warmth and support, can increase the risk of developing a personality disorder.


Symptoms of personality disorders can vary depending on the type of disorder, but some common characteristics include:

  • Inflexible patterns of thinking, feeling, and behaving that deviate from cultural and societal norms
  • Difficulty in forming and maintaining relationships
  • Difficulty in regulating emotions and impulses
  • Difficulty in adapting to change
  • Extreme reactions to stress


Diagnosis of a personality disorder typically involves a thorough evaluation by a mental health professional, such as a psychiatrist or psychologist. They will conduct a patient interview, review the patient’s medical and psychiatric history, and use diagnostic tools such as structured interviews, questionnaires, and rating scales to assess the severity of symptoms. It’s important to note that diagnosis of personality disorder can be difficult as the symptoms may overlap with other mental health conditions and a multi-disciplinary approach is usually taken.


Treatment options for personality disorders include:

  • Psychotherapy such as cognitive-behavioural therapy (CBT) and dialectical behavior therapy (DBT)
  • Medications such as antidepressants and antipsychotics
  • Group therapy and support groups
  • Family therapy: which can help educate and support family members, and help them understand how to best support the person with a personality disorder


It’s important to note that treatment for personality disorders is typically long-term and can be challenging, but with the right support, individuals can learn to manage their symptoms and improve their quality of life. It’s important to work closely with a healthcare professional to find the best treatment plan.
