Problem: What should I response to peer who write initial post about a brief diagnostic formulation (i.e., what you think is going on with Andy) which includes presenting symptoms, duration, severity of impairment, potential for self-harm or harm to others, and treatment plan (pharmacological and non-pharmacological interventions). .Potential diagnoses could be Schizophreniform disorder, given that his symptoms duration is less than 6 months but greater than one month and the presence of delusions, hallucinations, disorganized thoughts, and negative symptoms (González et al., 2024). Substance Induced Psychosis should be considered due to his frequent cannabis use and recent use of stimulants. Andy does not appear to be in a manic state accompanied by depressive states, so a bipolar diagnosis seems unlikely. Pharmacological interventions for Andy could include atypical antipsychotics such as Risperidone, Aripiprazole, or Olanzapine to help address both positive and negative symptoms while minimizing extrapyramidal side effects.
