“Odd” Personality Disorders

CLUSTER A:cluster a

The cluster of “odd” personality disorders includes:

People with these disorders display behaviors similar to, but not as extensive as, schizophrenia

  • Behaviors include extreme suspiciousness, social withdrawal, and peculiar ways of thinking and perceiving things
  • Such behaviors leave the person isolated
  • Some clinicians believe that these disorders are actually related to schizophrenia, and thus call them “schizophrenia-spectrum disorders”

Clinicians have learned much about the symptoms of odd personality disorders, but little of their causes or how to treat them.  In fact, people with these disorders rarely seek treatment.
