Symptoms of the central disorders of hypersomnolence extend beyond excessive daytime sleepiness to include non-restorative sleep, fatigue and cognitive dysfunction. They share much in common with myalgic encephalomyelitis/chronic fatigue syndrome, recently renamed systemic exertion intolerance disease, whose additional features include post-exertional malaise and orthostatic intolerance. We sought to determine the frequency and correlates of systemic exertion intolerance disease in a hypersomnolent population...

Introduction: The importance of obstructive sleep apnea in patients undergoing surgery with general anesthesia is well-defined, but the surgical and anesthetic implications of other sleep disorders are less clear. We sought to evaluate response to surgery with general anesthesia in patients with central disorders of hypersomnolence or restless legs syndrome. Methods: We surveyed patients on their most recent surgical procedure with general anesthesia, querying about procedure, recovery, and any changes in sleep disorder symptomatology following the procedure...

PURPOSE OF REVIEW: To highlight and critically discuss the possibility that breathing abnormalities during hypersomnolent episodes are an additional clinical feature of Kleine-Levin Syndrome (KLS). RECENT FINDINGS: A computerized literature search of breathing abnormalities in patients with KLS disclosed two old and a single recent publication describing a total of six patients with sleep apnea during hypersomnolent episodes. SUMMARY: Owing to scarce reports on complete polysomnography during and in-between hypersomnic episodes of KLS, the possibility that breathing abnormalities are an additional clinical feature of this unique episodic sleep syndrome should be further studied...

OBJECTIVE:  Psychopharmacotherapy is essential in the treatment of many mental disorders. Adverse drug reactions (ADR) have impact on compliance and tolerability. Sleep disorders or impaired sleep may occur as ADRs of psychopharmacotherapy. Sleep disorders are associated with an increased risk for physical and mental illness and may impair cognition, impulse control, emotion regulation and mood. Objective of the following study was the systematic presentation of type and risk of sleep disorders/impairments of sleep of frequently prescribed psychotropic drugs...

Metabolomic profiling is an emerging technology in the clinical setting with immediate diagnostic potential for the population of patients with Inborn Errors of Metabolism. We present the metabolomics profile of two ABAT deficiency patients both pre- and posttreatment with flumazenil. ABAT deficiency, also known as GABA-transaminase deficiency, is caused by recessive mutations in the gene ABAT and leads to encephalopathy of variable severity with hypersomnolence, hypotonia, hypomyelination, and seizures. Through metabolomics screening of multiple patient tissues, we identify 2-pyrrolidinone as a biomarker for GABA that is informative in plasma, urine, and CSF...

Kleine-Levin syndrome (KLS) is a rare sleep disorder mainly affecting teenage boys in which the main features are intermittent hypersomnolence, behavioral and cognitive disturbances, hyperphagia, and in some cases hyper sexuality. Etiology is unknown, and there is no specific clinical or imaging test for this syndrome even though the illness has well-defined clinical features. Also, there is no effective treatment for KLS. KLS is self-limited, so the prognosis for these patients is not so bad. This study presents our case report and comprehensive workout that led to diagnosis which is primarily clinical...

The rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia characterized by dream-enacting behaviors related to the loss of the normal generalized skeletal muscle atonia during REM sleep, and shows REM sleep without atonia (RWA) during polysomnography (PSG). Patients with idiopathic RBD have been known to have a siginificantly increased risk of developing one of the α-synucleiopathies later in life, therefore the diagnosis of RBD is very important and must be dealt with carefully. A 51-year-old man was identified presenting dream-enacting behaviors and unpleasant dreams suggesting the diagnosis of RBD, in addition to snoring and excessive daytime sleepiness...

REVIEW
Elisa Evangelista, Régis Lopez, Yves Dauvilliers
Idiopathic hypersomnia (IH) is a poorly characterized orphan central disorder of hypersomnolence responsible for excessive daytime sleepiness (EDS), prolonged nighttime sleep and sleep inertia that often require long-term symptomatic stimulant medication. To date, no drug has currently the authorization for the treatment of IH patients worldwide. Areas covered: The authors reviewed data on pharmacological treatment of IH obtained from published literature (Medline/PubMed/Web of Science) and Clinicaltrial.gov database from 1997 to 2017...

Type 1 narcolepsy (NT1) is a chronic primary disorder of hypersomnolence characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations and disrupted nocturnal sleep. NT1 is linked to hypothalamic hypocretin deficiency, strongly associated with Human Leukocyte Antigen (HLA) marker DQB1*06:02 and of probable autoimmune origin. NT1 is usually associated with increased rates of overweight and obesity, and sometimes with increases in overnight blood pressure and increased rates of hypoventilation with raised CO2 levels overnight...

The reticular activating system is the part of the brain that maintains the sleep/wake cycle. Any damage to this region can cause hypersomnolence and drowsiness along with altered sensorium. This case presents a patient with cerebellar and midbrain stroke with infarct of the reticular activating system, leading to hypersomnolence, drowsiness, and altered sensorium.
