DSM 5 SP
- 2+ present for significant amount of 1MO period (less if successfully treated): at least one must be delusions, hallucinations, disorganised speech; and then also grossly disorganised/catatonic behaviour; negative symptoms
- level of functioning below normal
- disturbance persists for 6MO, with at least 1 MO with criterion 1 symptoms (active-phase symptoms) and may include prodromal or residual symptoms
- schizoaffective disorder and depressive or bipolar disorder with psychotic features ruled out
- disturbance not attributable to substance or medical condition
- if history of ASD or childhood onset communciation disorder, SP diagnosis only if prominent delusions or hallucinations also present for 1+ months
DSM5 Schizoaffective disorder
uninterrupted period of illness with major mood episode (major depressiove or manic) concurrent with criterion 1 of SP
delusions/hallucinations for 2+w in absence of major mood episode during lifetime illness duration
symptoms that meet criteria for a major mood episode are present for the majority of total duration of active and residual portions of illness
disturbance not attributable to substance or other medical condition
DSM5 Schizophreniform disorder
2+ of following for singificant portion of 1MO (less when treated): one of delusions, hallucinations; disorganised speech; and then also grossly disorganised/catatonic behaviour; negative symptoms
at least 1 MO but less than 6MO
Schizoaffective, MDD or BD with psychotic features ruled out
disturbance not attributable to substance or medical condition
DSM5 Brief psychotic disorder
1+ of following: at least one of one of delusions, hallucinations; disorganised speech; and then also grossly disorganised/catatonic behaviour
duration of episode at least 1D but less than 1M, eventual full return to premorbid function level
disturbance not better explained by MDD or BD with psychosis or another psychotic disorder, substance or medical condition
DSM5 Delusional disorder
1+ delusions for 1M or longer
Criterion 1 for SP never met (if hallucinations present, not prominent and related to delusions)

does not occur exclusively during course of SP, BD, MDD with psychosis, another psychotic disorder or ASD
SP 3 genetic contributors
de novo mutations
rare alleles of high risk
common alleles of low risk
de novo mutations
completely new variations in genetic code
