For many who suffer from some form of substance abuse disorder, drugs and alcohol, unfortunately, are not the only issue they face. The Substance Abuse and Mental Health Services Administration (SAMHSA) report that approximately 4 million Americans suffering from a mental health issue also suffer from a co-occurring substance abuse issue. (1)

Here we take a look at one mental health issue that has a high rate of co-occurrence with substance abuse: schizoid personality disorder.

What is Schizoid Personality Disorder?

Schizoid personality disorder is a rare mental illness that causes individuals to have A book with a series of pills for mood disordersdifficulty in normal social situations. People suffering from this disorder typically have a difficult time or lack of desire to form close personal relationships.

These individuals also tend to have a difficult time expressing emotions they may feel. This may come off as indifference to others, and often times lead to social isolation. (2)

What are the signs of Schizoid Personality Disorder?

The signs of schizoid personality disorder vary from individual to individual. The following are common symptoms of someone who may be suffering from schizoid personality disorder (3):

  • Preference for being alone rather than in social circles
  • Lack of close relationships
  • Lack of sexual relationships
  • Inability to experience pleasure
  • Difficulty with expressing emotions
  • Reacting inappropriately during normal social circumstances
  • Seemingly humorless, cold, or indifferent
  • Lacking motivation

Schizoid Personality Disorder and Addiction

Personality disorders, such as schizoid disorders, tend to go hand in hand with substance abuse disorders. (4) Many individuals who suffer from personality disorders attempt to manage their symptoms by using various drugs and/or alcohol.

These attempts to self-medicate using drugs and/or alcohol can often times lead to substance abuse disorders. (5)

Dual Diagnosis or Co-occurring Disorders

The reality is that many people who suffer from a substance abuse disorder will also suffer from one or more other mental health issues. This is known as dual-diagnosis. It is crucial to deal with both the substance abuse issue and the mental health issue at the same time, rather than separately.

If you or a loved one is suffering from both an addiction and mental health issues, it is crucial to find a treatment center that specializes in dual diagnosis treatment.
