1. Criteria

DSM Criteria

Criterion A

  • Self-reported excessive sleepiness occurs despite a main sleep period lasting at least 7 hours.
  • The excessive sleepiness is accompanied by recurrent periods of sleep or lapses into sleep within the same day, a main sleep episode lasting more than 9 hours that is not restorative, or difficulty being fully awake after abrupt awakening.

DSM Criteria

Criterion B

  • The hypersomnolence occurs at least 3 times per week for at least 3 months.

DSM Criteria

Criterion C

  • The hypersomnolence causes significant distress or impairment.

DSM Criteria

Criterion D

  • The hypersomnolence is not better explained by another sleep disorder and does not occur exclusively during the course of another sleep disorder.

DSM Criteria

Criterion E

  • The hypersomnolence is not attributable to a substance or medication.

DSM Criteria

Criterion F

  • Coexisting mental or medical disorders do not adequately explain the predominant hypersomnolence complaint.

2. Context

  • Hypersomnolence disorder is about excessive sleepiness that persists even when the person appears to be getting enough main sleep. Patients often describe long, unrefreshing sleep, trouble getting fully awake, or repeated daytime sleep episodes that interfere with work, school, or safety.
  • Not just tired: This diagnosis is about true sleepiness rather than low energy alone, so it helps to separate sleepiness from depression, burnout, and medication side effects.
  • Duration: The problem needs to be recurrent and persistent, not just a short period of catch-up sleep after deprivation.
  • Rule-outs: Sleep deprivation, sleep apnea, circadian disruption, substance effects, and narcolepsy all need to be considered carefully before landing here.
  • Clinical focus: Quick self-report gauge of daytime sleepiness in common situations.

3. Validated scales

Epworth Sleepiness Scale

Quick self-report gauge of daytime sleepiness in common situations.

Sleep diary

Helps clarify whether the issue is true hypersomnolence or chronic sleep restriction.

Multiple Sleep Latency Test

Useful in specialist workup when narcolepsy or other central hypersomnia is being considered.

4. FDA approved treatments

Diagnosis-specific FDA indications

This prototype does not list a core DSM hypersomnolence-disorder-specific FDA medication indication; treatment usually depends on the underlying sleep diagnosis and specialist evaluation.

No diagnosis-specific FDA medication entry is listed in this prototype section.

Interventional psychiatry modalities

  • Interventional psychiatry modalities are not standard treatments for hypersomnolence disorder.
  • Management is usually based on sleep medicine workup, schedule correction, and cause-specific treatment.
  • ECT, TMS, and ketamine are not standard therapies here.
