Schizophrenia Spectrum

According to the DSM-5 psychotic experiences lay on a continuum where they are ranked in order of seriousness.


Schizotypal Personality Disorder

Definition: Persistent patterns of social and interpersonal shortfalls characterised by grave uneasiness with and increased inability for close relationships, along with cognitive and perceptual misrepresentations and odd behaviour. All this should be present at the onset of adulthood and is evident in various contexts.


Five or more of the following.

  1. Ideas of reference – Odd beliefs or magical thinking that affects behaviour and is inconsistent with cultural/societal norms
  2. Bizarre perceptual experiences including bodily illusions
  3. Strange thinking and speech
  4. Suspiciousness or Paranoia
  5. Unbecoming or Restricted affect
  6. Peculiar or Eccentric Behaviour
  7. Lack of close friends other than blood relatives
  8. Excessive social anxiety – doesn’t decrease with familiarity and is often linked with paranoid fears instead of negative self-judgement.

Delusinal Disorder

Delusional disorder is characterized by the presence of either strange or not too strange delusions which last for at least one month. People who have this disorder generally don’t experience a much harm to their daily functioning in social, occupational, or other settings.

Type (the types are allocated based on the prevalent delusional theme):

  • Erotomanic Type – delusions that someone, usually of high status, is in love with the person
  • Grandiose Type – delusions of exaggerated worth, knowledge, identity, power, or relationship to an idol or famous person
  • Jealous Type – delusions that one’s partner is unfaithful
  • Persecutory Type – delusions that the individual (or someone close to the person) is being treated with some malice.
  • Somatic Type – delusions that one has some physical flaw or medical condition
  • Mixed Type – delusions linked to more than one of the above types but no one theme predominates
  • Unspecified Type – delusions that cannot be linked to any of the above types.
