Clinical Vignette
Patient: "Ms. R," 35-year-old elementary school teacher, brought to the emergency department by her sister 4 days after learning of her husband's sudden death in a car accident.
Chief Concern: Patient's sister: "She started talking to her dead husband yesterday. She says she can hear him calling her name. She hasn't slept in 3 days and she's not making any sense."
History of Present Illness: Four days ago, Ms. R was informed that her husband of 8 years died in a motor vehicle accident. She was in acute emotional distress but initially coherent. Over the following 48 hours, she became increasingly agitated, stopped sleeping, and began hearing her husband's voice calling her name (auditory hallucinations). She developed the belief that her husband was still alive and being held at the hospital (delusion). Her speech became disorganized, shifting rapidly between topics. She attempted to drive to the hospital at 3 AM to 'rescue' her husband and was stopped by her sister. She has eaten minimally in 4 days. She has no prior psychiatric history and was described by her sister as 'the most stable person I know' prior to this event.
Past Psychiatric History: No prior psychiatric history. No prior psychotic episodes. No substance use.
Family History: No family history of psychotic disorders. Father treated for depression.
Mental Status Exam: Agitated, tearful. Speech rapid and disorganized (frequent derailment). Reports hearing husband's voice. Maintains deceased husband is alive. Oriented to person but confused about date and location. Affect labile (shifts between wailing and inappropriate calm). No suicidal ideation. Insight absent.
Step 1: Brief Psychotic Disorder DSM-5-TR Criteria
Criterion A: Presence of one or more of the following: (1) delusions, (2) hallucinations, (3) disorganized speech, (4) grossly disorganized or catatonic behavior. At least one must be (1), (2), or (3).
Auditory hallucinations (hearing deceased husband's voice). Delusion (husband is alive and being held at hospital). Disorganized speech (derailment). Three of four Criterion A features present, including required items 1-3. MET.
Criterion B: Duration of an episode is at least 1 day but less than 1 month, with eventual full return to premorbid level of functioning.
Psychotic symptoms began approximately 2 days ago (day 2 after the stressor). Current duration is 2 days. The episode has not yet resolved, so this criterion is provisionally met pending full resolution within 30 days. PROVISIONALLY MET.
Criterion C: The disturbance is not better explained by Major Depressive or Bipolar Disorder with psychotic features, Schizophrenia, Catatonia, or is not attributable to substance or medical effects.
No prior mood disorder. No substance use. No medical condition identified. Onset directly followed a severe psychosocial stressor. The presentation is not consistent with a primary mood disorder with psychotic features (no sustained depressive or manic syndrome beyond acute grief distress). MET.
Step 2: Specifiers
DSM-5-TR provides three specifiers for Brief Psychotic Disorder based on the relationship to stressors:
With marked stressor(s) — brief reactive psychosis
The sudden death of a spouse is an objectively severe psychosocial stressor. Psychotic symptoms began within 48 hours of learning of the death. The temporal relationship between stressor and psychosis onset is clear. THIS SPECIFIER APPLIES.
Without marked stressor(s)
N/A — a marked stressor is identified. DOES NOT APPLY.
With peripartum onset
Not applicable. No recent pregnancy. DOES NOT APPLY.
Step 3: Differential Considerations
| Feature | Brief Psychotic Disorder | Acute Stress Disorder | Schizophreniform | This Patient |
|---|---|---|---|---|
| Duration | 1 day to <1 month | 3 days to 1 month | 1 to 6 months | BPD: 2 days so far |
| Psychotic symptoms | Required (criterion A) | Not required | Required | Full psychosis present |
| Stressor relationship | May or may not follow stressor | Requires traumatic event | No stressor required | Clearly follows stressor |
| Dissociation | Not primary feature | Core feature | Not primary | Not primary |
| Full recovery expected | Yes (return to premorbid) | Resolves or progresses to PTSD | Variable | Expected given premorbid stability |
| Prior functioning | Typically good | Variable | Variable | Excellent premorbid functioning |
Differential Summary
The presence of frank psychotic symptoms (hallucinations, delusions, disorganized speech) exceeds the dissociative and anxiety features typical of Acute Stress Disorder. The brief duration (<1 month anticipated) and clear stressor relationship distinguish this from Schizophreniform Disorder.
Diagnostic Formulation
Diagnostic Conclusion
Brief Psychotic Disorder, with marked stressor (F23): Criterion A met (hallucinations, delusions, disorganized speech). Duration 2 days (within 1 day to <1 month window). Clear temporal relationship to spouse's death (marked stressor specifier). No prior psychiatric history. Excellent premorbid functioning. Provisional diagnosis pending full resolution within 30 days.
Teaching Points
- Brief Psychotic Disorder is differentiated from Schizophreniform Disorder solely by duration: BPD resolves within 1 month, while Schizophreniform persists for 1-6 months. If symptoms persist beyond 30 days, the diagnosis must be revised.
- The 'with marked stressor' specifier (historically called 'brief reactive psychosis') acknowledges that psychotic episodes can be precipitated by overwhelming psychosocial stressors. The stressor must be objectively severe, not merely subjectively distressing.
- Grief-related psychotic experiences (hearing the deceased's voice, sensing their presence) are common and usually do not constitute psychosis. The distinction is whether these experiences are accompanied by loss of reality testing, disorganized thinking, and functional impairment. In this case, the patient developed a fixed delusion (husband is alive) and disorganized behavior (3 AM rescue attempt), which exceeds normal grief phenomena.
- Treatment is supportive and pharmacological. Brief antipsychotic treatment (low-dose second-generation antipsychotic) can manage acute symptoms. Benzodiazepines may address agitation and insomnia. The anticipated course is full recovery, and long-term antipsychotic maintenance is typically unnecessary.
- Follow-up monitoring is essential: if symptoms persist beyond 1 month, the diagnosis shifts to Schizophreniform Disorder. If a major depressive episode emerges during resolution, MDD with psychotic features should be considered.
