Psychosis or need for hospitalization immediately classifies the episode as mania rather than hypomania.
Side by side
Mania causes elevated or irritable mood lasting at least 1 week or any duration if hospitalization is required, with marked functional impairment or psychotic features.
Hypomania lasts at least 4 days with clear mood and energy change but no psychosis, no hospitalization need, and no marked social or occupational impairment.
Bipolar mood dysregulation produces severe catecholaminergic and circadian disruption causing loss of judgment and behavioral control.
A milder bipolar-spectrum mood elevation occurs without psychotic disorganization or dangerous functional collapse.
Diagnosis is clinical after excluding substances and thyroid disease; mania severity is marked by psychosis, severe insomnia, pressured speech, and inability to maintain safety or function.
Hypomania remains clinically diagnosed with preserved baseline function and absence of delusions, hallucinations, or severe agitation needing inpatient containment.
The trap
High productivity and reduced sleep can be misread as benign hypomania even when grandiosity and unsafe spending are escalating; impairment severity and safety risk determine urgent treatment setting.
The repair move
Next best step: if mania with psychosis or dangerous behavior is present, hospitalize for safety and start rapid control with an antipsychotic such as olanzapine 10 mg IM for severe agitation or risperidone 1 to 2 mg PO twice daily, then add a mood stabilizer such as lithium 300 mg PO two to three times daily or valproate 20 mg/kg/day. If symptoms are hypomanic without danger, initiate outpatient mood-stabilizing therapy and close follow-up.
Try a free question
CoreA 29-year-old woman has elevated mood, decreased need for sleep, and increased goal-directed activity for 5 days. She is still working and has no psychosis or dangerous behavior. BP 124/78 mm Hg, HR 92/min, temp 36.8 C. What is the most likely diagnosis?
Show answer and explanation
Answer: B. Hypomania. Duration of at least 4 days without marked impairment or psychosis supports hypomania.
Why the other choices are tempting
- A. Wrong because criteria for marked impairment, psychosis, or hospitalization are not present.
- C. Wrong because cyclothymia requires chronic fluctuating subthreshold symptoms over years.
- D. Wrong because no persistent psychotic syndrome independent of mood is described.
- E. Wrong because attention fluctuation and acute medical trigger features of delirium are absent.
