Interactive Decision Tree
Algorithm Steps
- ▶Start
First Episode Psychosis Suspected
Patient presenting with new-onset psychotic symptoms
- ●Action
Comprehensive Assessment
Evaluate symptoms, history, and function
- Psychotic symptoms: hallucinations, delusions, disorganization
- Duration of symptoms and DUP (duration untreated psychosis)
- Prodromal symptoms history
- Family history of psychosis
- Substance use history (cannabis, stimulants)
- Developmental history
- Baseline functioning and functioning decline
- ●Action
Medical Workup
Rule out organic causes
- CBC, BMP, LFTs, TFTs
- Urine drug screen (comprehensive)
- HIV, syphilis (RPR/VDRL)
- Consider: B12, folate, ANA, anti-NMDAR
- Brain MRI (first episode)
- Consider LP if autoimmune suspected
- ◆Decision
Identifiable Cause?
Medical, neurological, or substance-induced?
- ●Action
Treat Underlying Cause
Address primary etiology
- Substance-induced: Abstinence, may resolve
- Medical: Treat underlying condition
- Autoimmune: Immunotherapy
- Re-evaluate psychosis after treatment
- ●Action
Primary Psychotic Disorder
Initiate antipsychotic treatment
- ●Action
Second-Generation Antipsychotic (SGA)
First-line treatment
- Start LOW, go SLOW (FEP very sensitive)
- Aripiprazole: 2-5mg, target 10-15mg
- Risperidone: 0.5-1mg, target 2-4mg
- Olanzapine: 2.5-5mg, target 10-15mg
- Paliperidone: 3mg, target 6mg
- Ziprasidone: 20mg BID, target 60-80mg BID
- Lower doses often effective in FEP
- ●Action
Metabolic Monitoring
Baseline and ongoing
- Weight, BMI, waist circumference
- Fasting glucose and lipid panel
- Blood pressure
- Prolactin if symptomatic
- ECG if using ziprasidone
- Monitor at 4, 8, 12 weeks, then quarterly
- ◆Decision
Response at 4-6 Weeks?
Adequate trial at therapeutic dose
- ●Action
Good Response
Continue current treatment
- Continue antipsychotic at effective dose
- Minimum 1-2 years after first episode
- Consider longer if severe episode/poor insight
- Add psychosocial interventions
- ●Action
Psychosocial Interventions
Essential adjuncts to medication
- Coordinated Specialty Care (CSC) program
- Individual or family therapy
- Supported employment/education
- Cognitive behavioral therapy for psychosis (CBTp)
- Social skills training
- Substance abuse treatment if needed
- Family psychoeducation
- ✓Outcome
Long-term Management
Recovery-oriented care
- Many FEP patients achieve remission
- Relapse prevention is key
- Monitor for tardive dyskinesia annually
- Address comorbidities (depression, anxiety)
- Support functional recovery
- ●Action
Inadequate Response
Optimize or switch
- Ensure adequate dose and adherence
- Rule out substance use
- Consider switching to different SGA
- After 2 failed SGAs: Clozapine evaluation
- LAI (long-acting injectable) if adherence issue
- ⚠Warning
Clozapine for Treatment Resistance
Most effective for refractory psychosis
- After 2 adequate SGA trials failed
- REMS enrollment required (US)
- Start 12.5-25mg, titrate slowly
- Target 300-450mg/day, check level
- Weekly ANC monitoring initially
- Most effective antipsychotic
