Difference between schizotypal, schizoid and schizophrenia?

Psychotic or not! Schizophrenia is a type of psychotic disorder characterized by symptoms, such as delusions or hallucinations, that indicate impaired contact with reality. "schizoid" and "schizotypal" refer to personality disorders (non-psychotic) with symptoms such as detachment from social relationships and other social and interpersonal deficits, beliefs, and experiences.
Differences. Schizotypal: a person with extremely eccentric thought patterns that border on psychotic, with bizarre, often unkempt appearance. Schizoid: a person largely indifferent to interpersonal relationships, detached from others and happy to be that way. Schizophrenia: these people are psychotic, which means they experience hallucinations of taste, touch, smell, vision and most commonly, hearing.
