Hypersomnia includes a group of disorders in which the primary complaint is excessive daytime sleepiness. Chronic hypersomnia is characterized by at least 3 months of excessive sleepiness prior to diagnosis and may affect 4% to 6% of the population. The severity of daytime sleepiness needs to be quantified by subjective scales (at least the Epworth sleepiness scale) and objective tests such as the multiple sleep latency test. Chronic hypersomnia does not correspond to an individual clinical… 
Diurnal and Nocturnal Sleep in Narcolepsy with Cataplexy
The diagnosis of narcolepsy with cataplexy is essentially clinical, but requires, whenever possible, a nocturnal PSG recording followed by an MSLT showing short mean sleep latencies and the presence of sleep-onset REM (REM) periods.
Excessive daytime sleepiness in cancer patients
Excessive daytime sleepiness in patients with cancer may be multifactorial, but persistent symptoms may indicate an underlying disorder of hypersomnolence.

Narcolepsy and Other Central Disorders of Hypersomnolence
Hypnagogic hallucinations are realistic dream‐like experiences around sleep onset whereas the term 'hypnopompic' is used if they occur from awakening, and Pharmacotherapy for sleepiness should be tailored towards the individual patient.
Classification of sleep disorders
The latest edition of the International Classification of Sleep Disorders, Second Edition (ICSD-2), published in 2005, combines a symptomatic presentation (insomnia) with one organized in part on the basis of pathophysiology (circadian rhythms) and in parts on body systems (breathing disorders).

The International Classification of Sleep Disorders, version 2, published in 2005 and currently undergoing revision, combines a symptomatic presentation with 1 organized in part on pathophysiology and in parton body systems to more easily differentiate between the disorders.
Are there sleep-specific phenotypes in patients with chronic fatigue syndrome? A cross-sectional polysomnography analysis
The results highlight the need to routinely screen for Primary Sleep Disorders in clinical practice and tailor sleep interventions, based on phenotype, to patients presenting with CFS.
The therapeutic goal is to optimize control of EDS through wake-promoting medications and nonpharmacological treatments.


Idiopathic hypersomnia. A series of 42 patients.
Stimulants are often beneficial and spontaneous improvement appears to be more common in patients with idiopathic hypersomnia than in narcolepsy, which is a rare syndrome in which clinical heterogeneity suggests a variable or multifactoral pathogenesis.
Hypersomnia associated with mood disorders: a new perspective.
Hypersomnia in bipolar depression: a comparison with narcolepsy using the multiple sleep latency test.
The complaint of sleepiness in the hypersomnic bipolar depressed patient appears to be related to the lack of interest, withdrawal, decreased energy, or psychomotor retardation inherent in the anergic depressed condition, rather than an increase in true sleep propensity or REM sleep propensity.
Is Excessive Daytime Sleepiness with Periodic Leg Movements during Sleep a Specific Diagnostic Category?
It is suggested that sleepy patients who presented with excessive daytime sleepiness and who showed an elevated number of periodic leg movements during sleep (PLMS) have a high propensity to sleep both at night and during the daytime and should not preclude the diagnosis of idiopathic hypersomnia.
Hypersomnia after head–neck trauma
A systematic approach is required when dealing with patients complaining of hypersomnia following a head–neck trauma, as extensive evaluation of pretrauma behavior supported the conclusion that the onset of symptomatic sleep-disordered breathing was associated with the trauma.
Hypersomnia with "sleep drunkenness".
Of 58 cases of hypersomnia with sleep drunkenness examined, 52 were apparently idiopathic; six cases were possibly symptomatic of organic brain disturbance, and except for extended sleep, no anomalies of sleep patterns were observed.
A cause of excessive daytime sleepiness. The upper airway resistance syndrome.
Nasal continuous positive airway pressure, used as an experimental tool, eliminated the daytime sleepiness, the transient arousals, and the abnormal upper airway resistance in a group of subjects investigated during nocturnal sleep and daytime naps.
Excessive daytime somnolence and increased rapid eye movement pressure in myotonic dystrophy.
Most DM1 patients did not have significant respiratory abnormalities on PSG to explain the manifested EDS, which implies an intrinsic hypersomnolence sometimes accompanied by abnormal REM pressure may be an integral part of EDS inDM1 patients.
A new method for measuring daytime sleepiness: the Epworth sleepiness scale.
The development and use of a new scale, the Epworth sleepiness scale (ESS), is described. This is a simple, self-administered questionnaire which is shown to provide a measurement of the subject's
Guidelines for the multiple sleep latency test (MSLT): a standard measure of sleepiness.
The multiple sleep latency test (MSLT) is used in the assessment and diagnosis of disorders of excessive somnolence and to evaluate daytime sleepiness in relation to various therapeutic or
