How Is Schizoid Personality Disorder Diagnosed?
If symptoms of this personality disorder are present, the doctor will begin an evaluation by performing a complete medical history and physical exam. Although there are no lab tests to specifically diagnose personality disorders, the doctor might use various diagnostic tests to rule out physical illness as the cause of the symptoms. If the doctor finds no physical reason for the symptoms, he or she might refer the person to a psychiatrist or psychologist, health care professionals who are specially trained to diagnose and treat mental illnesses. Psychiatrists and psychologists use specially designed interview and assessment tools to evaluate a person for a personality disorder.
