DefinitionBy Mayo Clinic staff
Schizoid personality disorder is a condition in which affected people avoid social activities and consistently shy away from interaction with others. If you have schizoid personality disorder, you may be seen as a loner, and you may feel as though you have no idea how to form personal relationships.
To others, you may appear dull or humorless. Because you don't tend to show emotion, you may appear as though you don't care about what's going on around you. However, although you may seem aloof, you may actually feel extremely sensitive and lonely.
The cause of schizoid personality disorder is unknown. Therapy and medications can help.
