Social isolation is also a symptom of schizoid and schizotypal personality disorders. The difference is, individuals with AVPD may have relationships, but they feel inadequate and anxious about them due to their feelings of inadequacy. Those with schizoid or schizotypal disorders completely isolate themselves from social connections. Characterizations of both schizoid and schizotypal personality disorders include cognitive deficits and eccentric behavior similar to those experienced by people with schizophrenia.
