Sleep Disorder Symptoms - Hypersomnia, Primary

Hypersomnia
Symptoms

The predominant complaint is excessive sleepiness for at least 1 month (or less if recurrent) as evidenced by either prolonged sleep episodes or daytime sleep episodes that occur almost daily.

The excessive sleepiness causes clinically significant distress or impairment in social, occupational, or other important areas of functioning.

The excessive sleepiness is not better accounted for by insomnia and does not occur exclusively during the course of another Sleep Disorder (e.g., Narcolepsy, Breathing-Related Sleep Disorder, Circadian Rhythm Sleep Disorder, or a Parasomnia) and cannot be accounted for by an inadequate amount of sleep.

The disturbance does not occur exclusively during the course of another mental disorder.

The disturbance is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition
