History of Present Illness
The patient is a 34-year-old female with a known psychiatric history presenting to the ED after being found by police directing traffic at a busy intersection at 3 AM while wearing a bathrobe. She has a 10-year history of psychiatric illness with multiple hospitalizations. Per records, she has experienced episodes of psychosis both during mood episodes and during periods of relative mood stability. Current episode began 2 weeks ago with decreased need for sleep, increased energy, pressured speech, and grandiose delusions that she has been selected by a divine entity to "restructure reality." She believes she can communicate with historical figures through her artwork and that her designs are transmitted to world leaders through "quantum channels." She has spent $15,000 in the past week on art supplies and electronics to build a "cosmic transmitter." She also reports hearing the voice of Leonardo da Vinci guiding her work. Per family, she stopped taking her medications 6 weeks ago, stating she was "cured."

Diagnosis
Schizoaffective Disorder, Bipolar Type, Current Episode Manic with Psychotic Features (F25.0)
DSM-5 Criteria Analysis:
- Major mood episode (manic) concurrent with Criterion A symptoms of schizophrenia (delusions, hallucinations)
- Delusions and hallucinations have been present for 2+ weeks in the absence of a major mood episode during illness lifetime (per prior records documenting psychotic symptoms between mood episodes)
- Mood episode symptoms present for majority of total illness duration
- Not attributable to substance use or medical condition
Distinguishing from Bipolar I with Psychotic Features:
- In bipolar disorder, psychotic symptoms occur exclusively during mood episodes
- This patient has documented history of persistent psychotic symptoms between mood episodes, meeting criteria for schizoaffective disorder
Treatment Plan
Acute Management:
- Involuntary psychiatric hold (danger to self due to impaired judgment)
- Restart lithium 600 mg BID, titrate to therapeutic level (0.8-1.0 mEq/L)
- Add olanzapine 10 mg at bedtime for acute psychosis and mood stabilization
- PRN olanzapine 5 mg IM for agitation
Pharmacotherapy Rationale:
- Combination mood stabilizer plus antipsychotic optimal for schizoaffective disorder
- Lithium for long-term mood stabilization and suicide risk reduction
- Olanzapine for acute mania and psychosis
Monitoring:
- Daily lithium levels until therapeutic
- Metabolic panel, renal function at baseline and periodically
- Fasting glucose and lipids (olanzapine metabolic risks)
- Weight monitoring
Psychoeducation:
- Discuss diagnosis and the chronic nature requiring maintenance treatment
- Medication adherence counseling with exploration of barriers
- Discuss warning signs of relapse
- Financial counseling referral for spending recovery
Discharge Planning:
- Structured outpatient program
- Consider long-acting injectable antipsychotic for adherence
- Family involvement in treatment planning
- Return to work program with vocational rehabilitation
