The 10 Personality Disorders

Schizoid Personality Disorder


This post is intended to list characteristics of personality disorders, causes & treatments.

*These are characteristics often observed in a personality disorder though every feature may not apply to each specific personality disorder. Appreciate what is of value to you in this post and leave the rest.

Individuals with a personality disorder often experience chronic, pervasive difficulty with relationships, impulse control, & emotions. The features may be present in childhood, often become prominent in teen years, but often a diagnosis is withheld until adulthood.

Typically, a personality disorder is in sync with one’s ego. Due to this the person may lack self-awareness and externalize the problems associated with their personality disorder. Personality disorders can co-occur.

In order for a diagnosis a person must exhibit difficulty in at least one of the four, (among other criteria specific to the personality disorder);

  • Distorted thinking
  • Problematic emotional responses
  • Over or under regulated impulse control
  • Interpersonal difficulties

Data supports that any person with a personality disorder is more likely to have a substance use disorder. Though, sometimes it can be difficult to differentiate which is causing the other. Personality disorders should be diagnosed with caution.

Personality disorders are grouped into clusters based on common similarities;

Cluster A: Social withdrawal or awkwardness driven by distorted thinking

Cluster B: Dramatic, impulsive and emotional thinking/behavior

Cluster C: Driven by fear

*Schizoid personality disorder is NOT in occurrence with schizophrenia, bipolar, autism, or any other disorder with psychotic features, though it is recognized as a precursor to schizophrenia



Some research supports that early environmental factors contribute to schizoid personality disorder; such as if caregivers were cold, not attentive to emotional needs, or neglectful.  Evidence more strongly supports that heritability contributes. It is widely accepted that a combination of brain chemistry, genetics, childhood trauma, and environmental factors are the causes of schizoid personality disorder.

“I dream my painting and I paint my dream.” Vincent Willem van Gogh


Vincent Willem Van Gogh was thought to have Schizoid Personality Disorder.

“What am I in the eyes of most people — a nonentity, an eccentric, or an unpleasant person — somebody who has no position in society and will never have; in short, the lowest of the low. All right, then — even if that were absolutely true, then I should one day like to show by my work what such an eccentric, such a nobody, has in his heart. That is my ambition, based less on resentment than on love in spite of everything, based more on a feeling of serenity than on passion.

Though I am often in the depths of misery, there is still calmness, pure harmony and music inside me. I see paintings or drawings in the poorest cottages, in the dirtiest corners. And my mind is driven towards these things with an irresistible momentum.” Vincent Willem van Gogh
