Disorders of sleep and wakefulness occur in about 60-98% of patients with Parkinson's disease (PD). The majority of research on the scale and nature of the disorders was performed in patients treated with antiparkinsonian drugs, and, therefore, the true picture of sleep disorders was interfering with side effects of therapy. The spectrum of these disorders in PD patients is broad and includes insomnia, parasomnia and hypersomnia. The main symptoms of insomnia are difficulty in maintaining sleep, associated with nocturia, rapid eye movement (REM) sleep behavior disorder (RBD), night cramps, akinesia and tremor...

The aim of this study was to find electroencephalographic (EEG) changes in subjects with drug-naïve idiopathic rapid eye movement sleep behavior disorder (iRBD) who had no cognitive impairment. A total of 57 iRBD patients confirmed by polysomnography (PSG) and 33 sex and age-matched healthy controls were included and their waking EEG was recorded from five cortical regions for 15min. Power spectral analyses by fast Fourier transforms were performed on EEG data. In PSG data, the iRBD patients showed sleep disturbances of short total sleep time, decreased sleep efficiency, increased sleep latency and frequent awakening compared to controls...

Sleep disorders are among the most common non-motor manifestations in Parkinson's disease (PD) and have a significant negative impact on quality of life. While sleep disorders in PD share most characteristics with those that occur in the general population, there are several considerations specific to this patient population regarding diagnosis, management, and implications. The available research on these disorders is expanding rapidly, but many questions remain unanswered. We thus conducted a systematic review of the literature published from 2005 to 2015 on the following disorders of sleep and wakefulness in PD: REM sleep behavior disorder, insomnia, nocturia, restless legs syndrome and periodic limb movements, sleep disordered breathing, excessive daytime sleepiness, and circadian rhythm disorders...

PURPOSE: REM (rapid eye movement) sleep behavior disorder (RBD) is characterized by increased muscle tone and violent limb movements and is a usual symptom of the early stages of Parkinson's disease (PD). PD patients with RBD represent faster motor and cognitive dysfunction progression. However, there are limited studies on possible structural brain changes underpinning this disorder. METHODS: Diffusion magnetic resonance imaging (DMRI) was used to assess whether microstructural abnormalities in the brain of 23 RBD positive PD are detectable compared to 31 RBD negative PD...

: Patients with Parkinson's disease (PD) and REM sleep behavior disorder (RBD) show mostly unimpaired motor behavior during REM sleep, which contrasts strongly to coexistent nocturnal bradykinesia. The reason for this sudden amelioration of motor control in REM sleep is unknown, however. We set out to determine whether movements during REM sleep are processed by different motor networks than movements in the waking state. We recorded local field potentials in the subthalamic nucleus (STN) and scalp EEG (modified 10/20 montage) during sleep in humans with PD and RBD...

A reduction in the activity of GABAA receptors, particularly α5 subunit-containing GABAA receptors (α5GABAARs), has been implicated in the etiology of Autism Spectrum Disorders (ASD). Genetically modified mice that lack α5GABAARs (Gabra5(-/-)) exhibit autism-like behaviors and both enhanced and impaired learning and memory, depending on the behavioral task. The aim of this study was to examine the electroencephalogram (EEG) activity and sleep-wake behaviors in Gabra5(-/-) mice and wild-type mice. In addition, since some individuals with ASD can exhibit elevated innate immune response, mice were treated with lipopolysaccharide (LPS; 125mg/kg intraperitoneal injection) or vehicle and EEG and sleep-wake patterns were assessed...

Sleep disturbances are common in adults with PTSD and range from insomnia and nightmares to periodic leg movements and disruptive nocturnal behaviors. Together these findings suggest profound disturbances in rapid eye movement (REM) and non-REM (NREM) sleep, although there is a lack of consensus regarding a distinct profile of objective sleep disturbances associated with PTSD. Prospective, longitudinal studies have established that sleep disturbances represent a risk factor for the development and course of PTSD, suggesting that sleep is an important neurobiological mechanism in the etiology and maintenance of this disorder...

In recent years sleep-related memory consolidation has become a central topic in the sleep research field. Several studies have shown that in healthy individuals sleep promotes memory consolidation. Notwithstanding this, the consequences of sleep disorders on offline memory consolidation remain poorly investigated. Research studies indicate that patients with insomnia, obstructive sleep apnea, and narcolepsy often exhibit sleep-related impairment in the consolidation of declarative and procedural information...

PURPOSE: Data on the prevalence of RBD in patients with PAF are limited, with discrepancies in the literature regarding prevalence. We aimed to provide further data on this association with a series of eight patients with PAF. METHODS: We reviewed the electronic medical records of all patients seen at the Stanford neurology clinics from 2012 to 2016 who were given a provisional diagnosis of PAF (343 patients), and further screened by procedure codes to identify those patients who underwent both attended video-polysomonography and autonomic testing (18 patients), and met strict exclusionary criteria (8 patients)...

Youngsin Jung, Erik K St Louis
REM sleep behavior disorder (RBD) is a common parasomnia disorder affecting between 1 and 7 % of community-dwelling adults, most frequently older adults. RBD is characterized by nocturnal complex motor behavior and polysomnographic REM sleep without atonia. RBD is strongly associated with synucleinopathy neurodegeneration. The approach to RBD management is currently twofold: symptomatic treatment to prevent injury and prognostic counseling and longitudinal follow-up surveillance for phenoconversion toward overt neurodegenerative disorders...

Importance: Mutations in the glucocerebrosidase (GBA) gene are a risk factor for the development of dementia with Lewy bodies (DLB). These mutations are common among Ashkenazi Jews (AJ) and appear to have an effect on the natural history of the disease. Objectives: To evaluate the clinical and genetic characteristics of an AJ cohort of patients diagnosed with DLB, assess the association of phenotype of DLB with GBA mutations, and explore the effects of these mutations on the clinical course of the disease...
