Schizotypal Disorder Resources

ICD-10 criteria:

A disorder characterized by eccentric behaviour and anomalies of thinking and affect which resemble those seen in schizophrenia, though no definite and characteristic schizophrenic anomalies occur at any stage. The symptoms may include:

• a cold or inappropriate affect;
• anhedonia;
• odd or eccentric behaviour;
• a tendency to social withdrawal;
• paranoid or bizarre ideas not amounting to true delusions;
• obsessive ruminations;
• thought disorder and perceptual disturbances;
• occasional transient quasi-psychotic episodes with intense illusions, auditory or other hallucinations, and delusion-like ideas, usually occurring without external provocation.
  

DSM-IV-TR criteria:

A pervasive pattern of social and interpersonal deficits marked by acute discomfort with, and reduced capacity for, close relationships as well as by cognitive or perceptual distortions and eccentricities of behavior, beginning by early adulthood and present in a variety of contexts, as indicated by five (or more) of the following:

• ideas of reference (excluding delusions of reference);
• odd beliefs or magical thinking that influences behavior and is inconsistent with subcultural norms (e.g., superstitiousness, belief in clairvoyance, telepathy, or "sixth sense"; in children and adolescents, bizarre fantasies or preoccupations);
• unusual perceptual experiences, including bodily illusions;
• odd thinking and speech (e.g., vague, circumstantial, metaphorical, overelaborate, or stereotyped)
• suspiciousness or paranoid ideation;
• inappropriate or constricted affect;
• behavior or appearance that is odd, eccentric, or peculiar;
• lack of close friends or confidants other than first-degree relatives;
• excessive social anxiety that does not diminish with familiarity and tends to be associated with paranoid fears rather than negative judgments about self.
