Everything You Need to Know About Personality Disorders

It is difficult to describe the exact meaning of the word ‘personality’. That is because the word ‘personality’ can be described in many ways. For instance, shyness is used to describe the nature of a person, how he behaves in the company of others. At the same time, in mental health, personality refers to the behavior and pattern that evolves from biological and environmental factors. It includes the ways how a person feels, behaves and thinks.

An individual’s personality is determined by surroundings, experiences and inherited characteristics. Whereas, a personality disorder is a type of mental disorder that affects an individual life in many ways. Let us now deeply understand the types of personality disorders, its signs, and diagnosis.

Personality Disorders can be defined as a kind of personality trait and behavior that describes an individual who faces challenges when interacting with other people. People with a personality disorder may find it difficult than normal people to react to the changes in life. It is considered a mental illness. The person may become anxious or upset when performing everyday functions in the schools or at the workplace.

In the DSM (Diagnostic and Statistical Manual of Mental Disorders), here’s how the American Psychiatric Association explains personality disorder-

‘An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the culture of the individual who exhibits it.’

When personality disorder is related to mental illness, Exploding Head Syndrome is a sleeping disorder in which a person hears loud noises of gunshot or crash while sleeping.

How is a Personality Disorder Identified?

In case a doctor suspects you for a personality disorder, diagnosis may be observed through:

  • Discussion about Thoughts – In this, the doctor discusses your thoughts, feelings, and behavior which may include a lot of questions to help identify the name of the disorder. It is referred to as a psychiatric evaluation.
  • Physical Examination – The doctor may ask-in depth questions about your health. The exam may include a screening test for drugs or alcohol.
  • Comparison of Symptoms – The doctor may compare your current symptoms to the Diagnostic Statistical Manual of Mental Disorders (DSM-5).
