Non-motor Symptoms in Chinese Patients With Isolated Generalized Dystonia: A Case-Control Study.

Front Neurol 2020 8;11:209. Epub 2020 Apr 8.

Department of Neurology, Peking Union Medical College Hospital, Peking Union Medical College and Chinese Academy of Medical Sciences, Beijing, China.

Previous studies have indicated that non-motor symptoms are primary problems in focal dystonia, but limited data are available about non-motor problems and their correlation with motor severity in generalized dystonia (GD). In the present study, we performed a case-control study and enrolled isolated inherited or idiopathic GD patients and age- and sex-matched healthy controls (HC). Clinical characteristics, motor symptoms, non-motor problems, including psychiatric co-morbidity, sleep problems, fatigue, and quality of life (QoL) were assessed in both groups using various rating scales and assessments.

Effects of repetitive transcranial magnetic stimulation in subjects with sleep disorders.

Sleep Med 2020 Jul 19;71:113-121. Epub 2020 Feb 19.

Department of Neurology, Christian Doppler Klinik, Paracelsus Medical University, Salzburg, Austria; Centre for Cognitive Neurosciences Salzburg, Salzburg, Austria; University for Medical Informatics and Health Technology, UMIT, Hall in Tirol, Austria.

In this review, we aimed at identifying the studies that have employed repetitive transcranial magnetic stimulation (rTMS) in patients with sleep disorders. Low-frequency (LF) rTMS stimulating the right dorsolateral prefrontal cortex (DLPFC) or the posterior parietal cortex (PPC) was found to be effective to reduce cortical hyperexcitability and improve the sleep quality in subjects with chronic primary insomnia (PI). Both high-frequency (HF) and LF rTMS applied over the primary motor cortex or the supplementary motor cortex seem to have transient beneficial effects in patients with restless legs syndrome (RLS).

Neuroimaging of Narcolepsy and Primary Hypersomnias.

Neuroscientist 2020 Feb 28:1073858420905829. Epub 2020 Feb 28.

Brain and Mind Institute, Western University, London, Ontario, Canada.

Advances in neuroimaging open up the possibility for new powerful tools to be developed that potentially can be applied to clinical populations to improve the diagnosis of neurological disorders, including sleep disorders. At present, the diagnosis of narcolepsy and primary hypersomnias is largely limited to subjective assessments and objective measurements of behavior and sleep physiology. In this review, we focus on recent neuroimaging findings that provide insight into the neural basis of narcolepsy and the primary hypersomnias Kleine-Levin syndrome and idiopathic hypersomnia.

A Guide to Management of Sleepiness in ESKD.

Am J Kidney Dis 2020 05 23;75(5):782-792. Epub 2020 Jan 23.

Division of Sleep Medicine, Department of Medicine at the Perelman School of Medicine at the University of Pennsylvania, Philadelphia, PA.

Daytime sleepiness, also known as hypersomnolence, is common among patients receiving maintenance dialysis and following successful kidney transplantation. Sleepiness may be secondary to medical comorbid conditions, medication side effect, insufficient sleep syndrome, and sleep-disordered breathing or the result of a primary central disorder of hypersomnolence, such as narcolepsy. Unrecognized and untreated sleep disorders are associated with substantial morbidity and mortality among patients with end-stage kidney disease. Read More

Cerebrovascular disease encompassing both ischemic and hemorrhagic strokes are among the leading causes of disability and mortality globally. The current evidence strongly suggests that identifying and addressing sleep disorders should be a part of both primary and secondary stroke prevention. Stroke and sleep are 'bedfellows' since sleep disorders, including sleep-disordered breathing, parasomnias, sleep-related movement disorders, insomnia, and hypersomnia are intimately intertwined with co-morbid cardiovascular conditions and increase stroke risk.

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.

Idiopathic Hypersomnia Patients Revealed Longer Circadian Period Length in Peripheral Skin Fibroblasts.

Front Neurol 2018 7;9:424. Epub 2018 Jun 7.

Division of Sleep Medicine and Neuromuscular Disorders, Department of Neurology, University Hospital Muenster, Muenster, Germany.

The vast majority of living organisms have evolved a circadian rhythm of roughly 24 h in adaptation to ever-changing environmental conditions, such as the cycle of light and darkness. In some sleep disorders like idiopathic hypersomnia (IH) this adaptation is defective. As the etiology of this disease is largely unknown, we examined the circadian period length of patients suffering from IH. Read More

The inappropriate occurrence of rapid eye movement sleep in narcolepsy is not due to a defect in homeostatic regulation of rapid eye movement sleep.

Sleep 2018 06;41(6)

Center for Research in Neuroscience of Lyon (CRNL), SLEEP team, CNRS UMR5292, INSERM U1028, Université Claude Bernard-Lyon1, Lyon, France.

Narcolepsy type 1 is a disabling disorder with four primary symptoms: excessive-daytime-sleepiness, cataplexy, hypnagogic hallucinations, and sleep paralysis. The later three symptoms together with a short rapid eye movement (REM) sleep latency have suggested impairment in REM sleep homeostatic regulation with an enhanced propensity for (i.e. Read More
