Psychotic Disorders

The best way to study DSM for the exam is not to study diagnosis individually but in group based on differentials and similarities. To consider the differences based on timeline/duration. Considering Psychotic disorders, there are 8 types :

1. Schizophrenia                                         (lasts atleast 6 months)
2. Schizophreniform                                     (1- 6 months)
3. Schizoaffective                                        (2 weeks)
4. delusional disorder                                  (at least 1 month)
5. brief psychotic disorder                          (1day to 1 month))
6. shared psychotic disorder
7. psychotic disorder due to general medical condition
8. substance induced psychotic disorder
9. NOS (pschotic disorders not otherwise specified)

Basics to know

  • what are positive and negative symptoms of schizophrenia
  • what is bizarre and non bizarre delusions : non bizarre delusions are things that can actually happen. where there is possibility to happen. eg: when the client says the neighbor is spying on him. a bizarre delusion is something which can never happen.. eg: when client says the neighbor is spying, and use space/satellite to spy them or spying them from another planet
  • different types of schizophrenia : Paranoid, disorganized, catatonic, undifferentiated, residual
  • phases in schizophrenia : prodromal, acute, residual
  • Types of delusion : erotomanic, grandiose, jealous, somatic, persecutory, mixed type

Schizophrenia 


Schizoaffective disorder




 Delusional Disorder


things to keep in mind

  • distinguishing schizophrenia from  schizophreniform is based on the duration. while former needs at least 6 months duration of symptoms (1 month active phase symptoms) the later must be at least 1 month and less than 6 months, because if its going to be less than a month, then a diagnosis for brief psychotic disorder
  • brief psychotic, schizophreniform and schizophrenia differs in its timeline. BP- upto 1 month, schizophreniform is 1 month to 6 months and schizophrenia is over 6 months.
  • distinguishing schizophrenia from schizo affective is by considering  duration as well as mood symptoms. 
  • the difference between schizophrenia and delusioanl disorder is easy considering the nature of delusions. non bizarre delusions signify delusional disorder and absence of prominent symptoms of schizophrenia like hallucinations, negative symptoms
