Schizoid personality disorder is one of a group of conditions called "Cluster 'A' " or eccentric personality disorders. People with these disorders often appear odd or peculiar. People with schizoid personality disorder also tend to be distant, detached, and indifferent to social relationships. They generally are loners who prefer solitary activities and rarely express strong emotion. Although their names sound alike and they might have some similar symptoms, schizoid personality disorder is not the same thing as schizophrenia.
However, if it is diagnosed in a child or teen, the features must have been present for at least 1 year. Schizoid personality disorder is more prevalent in males than females. Its prevalence in the general population is between 3.1 and 4.9 percent. Like most personality disorders, schizoid personality disorder typically will decrease in intensity with age, with many people experiencing few of the most extreme symptoms by the time they are in the 40s or 50s.
Treatment likely will focus on increasing general coping skills, as well as on improving social interaction, communication, and self-esteem. Because trust is an important component of therapy, treatment can be challenging for the therapist, because people with schizoid personality disorder have difficulty forming relationships with others. Medication is generally not used to treat schizoid personality disorder itself. Drugs might, however, be prescribed if the person also suffers from an associated psychological problem, such as depression. Treatment of schizoid personality disorder typically involves long-term psychotherapy with a therapist that has experience in treating this kind of personality disorder. Medications may also be prescribed to help with specific troubling and debilitating symptoms.
