From the Guidelines
Hypersomnia is characterized by excessive daytime sleepiness despite adequate or prolonged nighttime sleep, with primary symptoms including difficulty staying awake during the day, falling asleep at inappropriate times, and prolonged sleep episodes. The symptoms of hypersomnia can be understood by examining the effects of treatments such as methylphenidate, which has been suggested for the treatment of idiopathic hypersomnia in adults, as indicated by the American Academy of Sleep Medicine clinical practice guideline 1. According to this guideline, the treatment of hypersomnia aims to improve excessive daytime sleepiness, disease severity, quality of life, and work/school performance/attendance.
Some key signs and symptoms of hypersomnia include:
- Difficulty staying awake during the day
- Falling asleep at inappropriate times
- Prolonged sleep episodes (often 10+ hours)
- Sleep that doesn't feel refreshing despite its length
- Sleep inertia or "sleep drunkenness," which causes confusion, disorientation, and grogginess upon waking
- Irritability, anxiety, decreased energy, restlessness, slow thinking or speech, loss of appetite, and difficulty remembering things
- Hallucinations, automatic behaviors (performing routine tasks without awareness), or sleep paralysis in some individuals
These symptoms typically interfere with daily functioning, affecting work performance, social relationships, and overall quality of life, as noted in the context of treating idiopathic hypersomnia with methylphenidate 1. It's essential to consider the potential causes of hypersomnia, including neurological disorders, medication side effects, sleep disorders like narcolepsy or sleep apnea, or idiopathic causes, to provide appropriate management and treatment.

Signs and Symptoms of Hypersomnia
The signs and symptoms of hypersomnia include:
- Excessive daytime sleepiness (EDS) 2, 3, 4, 5
- Long sleep times or pronounced difficulty in awakening 3, 4
- Cognitive dysfunction 3
- Impaired quality of life 3
- Sleep inertia, which is the feeling of grogginess upon waking 3
Diagnosis of Hypersomnia
Diagnosis of hypersomnia involves:
- A thorough sleep, medical, and psychiatric history 2
- Targeted clinical examination 2
- Actigraphy to measure sleep duration and sleep-wake patterns 2
- Polysomnography to assess for associated conditions such as sleep-related breathing disorders 2
- Multiple sleep latency testing to ascertain objective sleepiness and diagnose central disorders of hypersomnolence 2, 5
- Measurement of cerebrospinal fluid hypocretin-1 concentration 2
