Abstract: We present a case of a 27-year-old woman in whom idiopathic hypersomnolence was diagnosed in adolescence with adequate symptomatic control on daily dosage of 250 mg of modafinil. She maintained this dosage throughout her pregnancy and during the peripartum period, but did not breastfeed her newborn because of a lack of information on the transmission of modafinil in human breast milk. Samples of her breast milk were obtained at various times over a 24-hour period and analyzed using liquid chromatography mass spectrometry. Read More

The diaphragm is the main breathing muscle and contraction of the diaphragm is vital for ventilation so any disease that interferes with diaphragmatic innervation, contractile muscle function, or mechanical coupling to the chest wall can cause diaphragm dysfunction. Diaphragm dysfunction is associated with dyspnoea, intolerance to exercise, sleep disturbances, hypersomnia, with a potential impact on survival. Diagnosis of diaphragm dysfunction is based on static and dynamic imaging tests (especially ultrasound) and pulmonary function and phrenic nerve stimulation tests. Read More

Aim: Narcolepsy, encompassing excessive daytime sleepiness (EDS), cataplexy, sleep paralysis and hypnogogic hallucinations, was previously considered rare in childhood. Recently, cases of childhood narcolepsy have increased significantly and the reasons for this may include the increasing awareness of narcolepsy as well as the H1N1 vaccination. The aim of this study was to describe the clinical characteristics of childhood narcolepsy, specifically focusing on cataplexy subtypes that may facilitate early recognition of narcolepsy. Read More

An autoimmune-mediated process in the pathophysiology of narcolepsy type 1 (NT1) is highly suspicious, if this pathomechanism is transferable to other types of central disorders of hypersomnolence (CDH), is still controversial. The association of NT1 with HLA-class-II system implicates a T-cell-mediated autoimmunity, in which helper CD4+ T-cells and cytotoxic CD8+ T-cells may be pathogenic.This study aimed to identify specific immune profiles in peripheral blood (PB) and cerebrospinal fluid (CSF) in different types of CDH.

Depression, a risk factor for several serious diseases, is a highly prevalent and life-threatening psychiatric disorder. It can affect the individual's position in life and reduce the living standards. The research on the use of medicinal plants in treating this disease has increased enormously because of the possible low rehabilitation rate and side effects of available synthetic drugs, such as sexual dysfunction, nausea, fatigue, insomnia, hypersomnia, and weight gain.

Circadian rhythm sleep disorders (CRSD) result from a disturbed endogenous clock (intrinsic CRSD) or from a misalignment between the biological clock and an imposed environment (extrinsic CRSD). Among intrinsic CRSD, one distinguishes the delayed sleep-wake phase disorder, the advanced sleep-wake phase disorder, the irregular sleep-wake rhythm disorder and the non-24-hour sleep-wake rhythm disorder. Shift work disorder, jet lag disorder and circadian sleep-wake disorder not otherwise specified are extrinsic CRSD. Read More

Purpose Of Review: To update current knowledge regarding sleep disturbances and myotonic dystrophies so as to better understand if sleep symptoms may help in the early recognition of the two genetic subtypes: myotonic dystrophy type 1 (DM1) and myotonic dystrophy type 2 (DM2).
Recent Findings: Sleep-disordered breathing (SDB), restless legs syndrome, periodic limb movements in sleep, hypersomnia, and REM sleep dysregulation are frequently described in DM1 patients. SDB does not always explain hypersomnia, but a central dysregulation of sleep-wake modulation is reported mainly in DM1. Read More

Introduction: Obstructive sleep apnea (OSA) is highly prevalent and constitutes a major health hazard. Current pharmacotherapy is ineffective in correcting sleep-disordered breathing and is used adjunctively to address residual sleepiness. A new drug, solriamfetol, a selective norepinephrine-dopamine reuptake inhibitor, is the first drug of its class that is being considered by the US Food and Drug Administration (FDA) to treat excessive sleepiness in OSA and narcolepsy patients.

Narcolepsy and Other 'Central Disorders of Hypersomnolence' Abstract. 'Excessive daytime sleepiness', 'hypersomnia' in the sense of prolonged sleep need, 'tiredness' or 'fatigue' are frequent complaints in primary care, requiring a careful separation in view of a correct diagnostic. After exclusion of various internistic and neurologic causes by clinical and laboratory investigations and after exclusion of sleep apnoea syndrome or other causes of disturbed sleep by polysomnography, the ambiguous group of 'Central Disorders of Hypersomnolence' remains, including narcolepsy with and without cataplexy, idiopathic hypersomnia, and non-organic hypersomnia.

Essential hypersomnia (EHS) is a lifelong disorder characterized by excessive daytime sleepiness without cataplexy. EHS is associated with human leukocyte antigen (HLA)-DQB1*06:02, similar to narcolepsy with cataplexy (narcolepsy). Previous studies suggest that DQB1*06:02-positive and -negative EHS are different in terms of their clinical features and follow different pathological pathways. Read More

Sleep is an evolutionally conserved behavior from vertebrates to invertebrates. The molecular mechanisms that determine daily sleep amounts and the neuronal substrates for homeostatic sleep need remain unknown. Through a large-scale forward genetic screen of sleep behaviors in mice, we previously demonstrated that the mutant allele of the protein kinase gene markedly increases daily nonrapid-eye movement sleep (NREMS) amounts and sleep need.

Adequate alertness is necessary for proper daytime functioning. Impairment of alertness or increase in sleepiness results in suboptimal performance and adversely affects the quality of life. While some causes of somnolence are intrinsic to the brain circuitry and neurochemical architecture, others are due to maladaptive behaviors and disorders affecting the normal sleep homeostasis.

While the world reputation of Michel Jouvet in sleep research is based on his huge work on sleep and paradoxical sleep, especially in cats, a far less-known part of his activity was dedicated to investigate and take care of patients with neurological diseases. Indeed, he was also a physician, specialized in neurophysiology and working at the neurological hospital of Lyon. He was most interested first in patients with disorders of consciousness and secondly in those with sleep/wake disorders, and especially in modafinil for the treatment of patients with narcolepsy and idiopathic hypersomnia.

Introduction: Patients with obstructive sleep apnoea (OSA) often present with excessive daytime sleepiness (EDS) as measured by the Epworth Sleepiness Scale (ESS). However, the relationship between EDS and OSA severity as measured by the apnoea-hypopnoea index (AHI) remains inconsistent. We hypothesise that this may be due to the usage and equal weightage of apnoea and hypopnoea events used in determining AHI and that apnoea and hypopnoea load as measured by their total durations may be a better metric to use.
