Schizoid personality disorder is a rare illness that is characterised by avoidance of social situations and interaction with those around them. Patients who suffer from this personality disorder are said to have a restricted range of expressing their emotions.
If you have been described as a loner or someone who is dismissive of others and you face difficulties in forming relationships, you might be suffering from schizoid personality disorder. People may think that you do not care about anybody or anything happening around you because of your inability to express your feelings.
The cause of schizoid personality disorder has not yet been established. Studies suggest that psychotherapy and medications may have some benefits for patients.
