PURPOSE OF REVIEW: This article provides a description on clinical features and pathophysiology of the main sleep disorders observed in Machado-Joseph disease (MJD). RECENT FINDINGS: Pathological studies have clearly demonstrated that degenerative process in MJD is widespread in the nervous system, and not restricted to the cerebellum. Nonmotor manifestations are frequent and may include pain, cramps, dysautonomia, cognitive deficits, psychiatric manifestations, olfactory deficits, fatigue, nutritional issues, and sleep disorders...

STUDY OBJECTIVES: To examine the association between periodic limb movements in sleep (PLMS) and change in selected aspects of cognition in community-dwelling older men. METHODS: We studied 2,636 older men without dementia who underwent in-home polysomnography with measurement of the periodic limb movement index (PLMI) and periodic limb movement arousal index (PLMAI) using piezoelectric sensors. Random-effects models and logistic regression were used to examine the association between PLMI, PLMAI, and 3- to 4-y change in cognition...

OBJECTIVES: Altered brain iron homeostasis with regional iron deficiency has been previously reported in several studies of restless legs syndrome (RLS) patients. Inconsistencies still exist, however, in the reported iron changes in different brain regions and different RLS phenotypes. The purpose of this study was to assess differences in brain iron concentrations between RLS patients and healthy controls and their relation to severity of disease and periodic limb movement during sleep (PLMS)...

UNLABELLED: Measurement of muscle strength and activity of upper limbs of non-ambulant patients with neuromuscular diseases is a major challenge. ActiMyo® is an innovative device that uses magneto-inertial sensors to record angular velocities and linear accelerations that can be used over long periods of time in the home environment. The device was designed to insure long-term stability and good signal to noise ratio, even for very weak movements. In order to determine relevant and pertinent clinical variables with potential for use as outcome measures in clinical trials or to guide therapy decisions, we performed a pilot study in non-ambulant neuromuscular patients...

STUDY OBJECTIVES: Growing literature suggests that patients with restless legs syndrome (RLS) may be at increased risk for hypertension, heart disease, and stroke. Cerebral small vessel disease (SVD) is a known risk factor for clinical stroke. This study evaluated silent cerebral SVD by MRI in patients with RLS, in the absence of a history of previous clinical stroke or known stroke risk factors and taking into account disease duration. METHODS: Fifty-three patients with RLS < 10 y were prospectively recruited along with 44 with RLS > 10 y and 74 normal controls...

INTRODUCTION: Sleep disorders are common in Parkinson's Disease (PD). It can antedate the motor manifestations of PD. It is related primarily to the involvement of sleep regulating structures, secondary involvement through motor, depressive and dysautonomic symptoms and the tertiary involvement through anti-parkinsonian medications. AIM: The aim of our study is to evaluate the frequency and nature of the sleep abnormalities in Idiopathic Parkinson's Disease, analysing the sleep architecture using polysomnography and to correlate the results with the disease parameters...

Skeletal muscles comprise the largest organ system in the body and play an essential role in body movement, breathing, and glucose homeostasis. Skeletal muscle is also an important endocrine organ that contributes to the health of numerous body organs. Therefore, maintaining healthy skeletal muscles is important to support overall health of the body. Prolonged periods of muscle inactivity (e.g., bed rest or limb immobilization) or chronic inflammatory diseases (i.e., cancer, kidney failure, etc.) result in skeletal muscle atrophy...

Restless legs syndrome (RLS) or Willis-Ekbom Disease is a common, but frequently under- recognized and misdiagnosed condition seen in many subspecialty practices including neurology, sleep medicine, primary care and rheumatology. Periodic limb movements are a frequent co-morbid diagnosis in RLS. Despite prior beliefs that the condition was "benign", it has been demonstrated to have a considerable impact on sufferers quality of life, physically and psychologically, as well as socially. This chapter is meant as a comprehensive review of RLS encompassing epidemiology, pathophysiology, diagnosis, and treatment considerations...

BACKGROUND: Automated peritoneal dialysis (APD) is one of the fastest growing dialysis modalities. It is unknown whether sleep and mood are disturbed while performing repeated overnight exchanges. OBJECTIVES: In this report, we aim to describe and compare the prevalence of sleep-disordered breathing (SDB), periodic limb movements (PLMS), poor sleep quality (SQ), and depression among APD patients compared with stages 3b-5 (estimated glomerular filtration rate ≤44 ml/min/1...

BACKGROUND: Over the last decade aquatic exercise has become more and more popular. One of the latest trends is aqua-cycling, where participants sit on a water-resistant stationary bike and, while immersed chest deep in the water, combine continuous cycling with upper body exercises that utilise water resistance. Since stationary cycling and aquatic exercises are frequently recommended to patients with knee osteoarthritis, combining both would seem an obvious step, and an aqua-cycling exercise programme for patients with knee osteoarthritis has indeed been developed...

BACKGROUND: Children with medical complexity have a high prevalence of sleep disorders. However, outpatient polysomnography to evaluate for these conditions may be difficult to perform because of lack of skilled nursing care. The aim of this study was to explore polysomnography indications in hospitalized children and assess its impact on patient care. METHODS: Data from 85 inpatient polysomnographies of 70 children hospitalized between March and December 2014 were retrospectively collected...

Clinical features variability between familial and sporadic restless legs syndrome/Willis-Ekbom disease (RLS/WED) has been previously reported. With this retrospective cohort study, we aimed to determine the clinical and polysomnographic characteristics of 400 RLS/WED patients. Patients with familial RLS/WED were significantly younger than sporadic RLS/WED, while clinical and polysomnographic characteristics were similar in both groups. No difference was found for the age-at-onset between idiopathic and secondary RLS/WED...

There is a reported association between hypertension (HTN) and sleep disorders. The American Academy of Pediatrics recommends screening children with HTN for sleep disorders because sleep disorders increase the risk for cardiovascular disease. We quantified the frequency and severity of sleep disorders within our institution's hypertensive pediatric population and evaluated the effectiveness of performing nocturnal polysomnography (NPSG). In the hypertensive pediatric population referred for NPSG at our institution, 64% were diagnosed with obstructive sleep apnea (OSA) and/or periodic limb movement disorder...

Sleep disturbance is a common nonmotor phenomenon in Parkinson's disease (PD) affecting patient's quality of life. In this study, we examined the association between clinical characteristics with sleep disorders and sleep architecture patterns in a PD cohort. Patients underwent a standardized polysomnography study (PSG) in their "on medication" state. We observed that male gender and disease duration were independently associated with obstructive sleep apnea (OSA). Only lower levodopa equivalent dose (LED) was associated with periodic limb movement disorders (PLMD)...
