First-episode psychosis management

Initial Workup - Spotting the Signs

• Comprehensive Evaluation: History (medical, psychiatric, substance), physical & neurological exam, and Mental Status Exam (MSE).
• Laboratory Studies:
  • Blood: CBC, electrolytes, BUN, creatinine, LFTs, glucose, calcium, TSH, Vitamin B12/Folate.
  • Urine: Urinalysis and urine drug screen (UDS) are critical.
  • Serology: RPR/VDRL for syphilis, HIV screen.
• Neuroimaging:
  • CT or MRI of the brain to rule out structural abnormalities (e.g., tumors, stroke). MRI is preferred.
• Other Tests:
  • EEG if seizure activity is suspected.

⭐ High-Yield: Always rule out substance-induced psychosis, especially from cannabis, synthetics, and stimulants, as it can mimic primary psychotic disorders. A thorough substance use history and UDS are essential.

Pharmacotherapy - Picking the Potion

• Goal: Rapid symptom control with minimal side effects. Second-generation antipsychotics (SGAs) are first-line.
• Principle: Start low, go slow. Titrate to the lowest effective dose.

⭐ High-Yield: Shared decision-making is crucial. Patient preference and predicted side-effect profile (e.g., avoiding olanzapine in a patient with diabetes) should guide initial SGA selection.

Psychosocial Interventions - Beyond the Pills

A multi-faceted approach is key, often delivered via a Coordinated Specialty Care (CSC) model.

• Psychoeducation:
  • For both patient and family.
  • Focuses on understanding the illness, treatment rationale, and early warning signs of relapse.
• Family Psychoeducation & Therapy:
  • Aims to ↓ "Expressed Emotion" (criticism, hostility, over-involvement), a major relapse predictor.
• Cognitive Behavioral Therapy for psychosis (CBTp):
  • Does not eliminate psychosis, but helps patients develop coping strategies.
  • Targets distress associated with positive symptoms (e.g., voice-hearing).
• Supported Employment & Education (IPS):
  • Individual Placement and Support model.
  • Focuses on rapid return to work or school in mainstream settings.

⭐ Family psychoeducation is a cornerstone of care, demonstrated to decrease relapse rates and improve medication adherence significantly.

High‑Yield Points - ⚡ Biggest Takeaways

• Early intervention is critical for improving long-term prognosis in first-episode psychosis.
• Second-generation antipsychotics (SGAs) are first-line due to a more favorable side-effect profile.
• Initiate SGAs at a low dose and titrate slowly to enhance tolerability and minimize side effects.
• Mandatory metabolic monitoring (weight, glucose, lipids) is required for all patients on SGAs.
• Family psychoeducation is crucial for adherence and reducing relapse rates.
• Always screen for and address comorbid substance use.
• Integrate psychosocial therapies like CBTp for optimal functional recovery.
