Most people with idiopathic REM sleep behavior disorder (iRBD) have an underlying synucleinopathy, mainly Parkinson's disease (PD) or dementia with Lewy bodies, with median conversion time of 4 -9 y from iRBD diagnosis and of 11-16 y from symptom onset. (univr.it)
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. (jneurosci.org)
SIGNIFICANCE STATEMENT This study provides evidence that nocturnal movements during REM sleep in Parkinson's disease (PD) patients are not processed by the same corticobasal ganglia network as movements in the waking state. (jneurosci.org)
Slowness of movement (bradykinesia) is the fundamental and most characteristic deficit in patients with Parkinson's disease (PD) ( Marsden, 1989 ). (jneurosci.org)
At the Université de Montréal, Dr. Jacques Montplaisir, a psychiatrist and neurobiologist, is investigating the association between REM sleep behaviour disorders and Parkinson's disease. (parkinson.ca)
The vast majority of people with the sleep disorder (about one per cent of the general population) go on to develop either Parkinson's disease or dementia with Lewy bodies, another progressive neurological disease closely associated with Parkinson's. (parkinson.ca)
Up to 80 per cent of these sleep behaviour disorder patients will develop Parkinson's disease or dementia with Lewy bodies within the timeframe of about 10 years," says Montplaisir. (parkinson.ca)
Montplaisir has been conducting research into sleep disorders for decades, not knowing his work would lead to a connection with Parkinson's disease. (parkinson.ca)
Studies show that the gut microbiome in Parkinson's patients is different from the gut microbiome in healthy individuals. (stanford.edu)
What is not clear, however, is how these differences impact one's risk for developing Parkinson's Disease or how the different microbiome in Parkinson's patients impacts disease course. (stanford.edu)
Additionally, in Parkinson's patients there is chronic systemic inflammation due to excessive immune activity, and the gut microbiome is known to impact immune functioning. (stanford.edu)
Therefore, in this study we examine whether the differences in the microbiome of Parkinson's patients are associated with increased inflammatory markers in the blood, and whether the differences in microbiome impact immune cell activation. (stanford.edu)
Through this study, we hope to better understand the mechanism by which the microbiome in Parkinson's patients may be contributing to the disease. (stanford.edu)

New research suggests sleep apnea may disrupt the formation of new spatial memories. (psychcentral.com)
Sleep apnea is characterized by abnormal pauses in breathing or instances of shallow or infrequent breathing during sleep. (psychcentral.com)
In the new study, sleep specialists from New York University (NYU) used a unique technique to determine that sleep apnea may retard spatial memories. (psychcentral.com)
They found that sleep apnea can impair spatial memory in humans even when other sleep stages are intact. (psychcentral.com)
However, this is the first study to demonstrate the importance of REM sleep for spatial memory in humans, and to document the negative consequence of sleep apnea on spatial memory. (psychcentral.com)
We've shown for the first time that sleep apnea, an increasingly common medical condition, might negatively impact formation of certain memories, even when the apnea is limited to REM sleep," said Dr. Varga. (psychcentral.com)
Our findings suggest memory loss might be an additional symptom for clinicians to screen for in their patients with sleep apnea. (psychcentral.com)
Although sleep apnea can occur during any stage of sleep, it is often worst during REM sleep because of reduced muscle tone in the upper airway that naturally occurs during REM sleep. (psychcentral.com)
Some individuals, in fact, have apnea that only occurs during REM sleep. (psychcentral.com)
While the negative effects of sleep apnea on cardiovascular health have been more broadly studied, this work sheds light on important cognitive consequences of sleep apnea. (psychcentral.com)
In order to assess cognitive impact of REM sleep apnea, Dr. Varga and colleagues recruited 18 subjects with severe sleep apnea who also are treated with nightly use of a continuous positive airway pressure (CPAP) machine. (psychcentral.com)
On the other night, their use of CPAP was reduced during REM sleep, thus allowing sleep apnea to occur. (psychcentral.com)
However, when REM sleep was disrupted by sleep apnea, there was not only no improvement from baseline testing, but, in fact, subjects took four percent longer to complete the maze tests. (psychcentral.com)
Equally important, when sleep apnea occurred in REM sleep, subjects did not experience delayed reaction times on a separate test to measure attention, called a psychomotor vigilance test. (psychcentral.com)
Dr. Varga says that this suggests that sleepiness or lack of attention were not reasons for the decline in spatial memory, as indicated by the maze performance after experiencing sleep apnea in REM sleep. (psychcentral.com)
Sleep apnea is a common condition affecting four percent of Americans overall and as many as 25 percent of middle-aged men. (psychcentral.com)
Sleep apnea is thought to have two main detrimental effects: First, it creates numerous repetitive dips in the blood's oxygen levels. (psychcentral.com)
Second, sleep apnea creates numerous small arousals that interrupt sleep continuity. (psychcentral.com)
Investigators say that future research will focus on determining the contributions of each of these mechanisms of sleep apnea toward its effect on disruption of spatial memory. (psychcentral.com)

Researchers at Northwestern University report older adults who suffer from sleep disturbances such as sleep apnea and restless leg syndrome might enjoy a better night's sleep by cultivating a purpose in life. (neurosciencenews.com)
Novel studies investigating cannabinoids and obstructive sleep apnea suggest that synthetic cannabinoids such as nabilone and dronabinol may have short-term benefit for sleep apnea due to their modulatory effects on serotonin-mediated apneas. (springer.com)
Mechanisms of sleep-induced hypoxemia may be related to hypoventilation due to worsening mechanics, worsening ventilation-perfusion mismatching, decreased hypoxic respiratory drive, decreased hypercapnic respiratory drive, respiratory dysrhythmia of rapid-eye-movement (REM) sleep, decreased respiratory muscle activity (especially in REM sleep), increased upper-airway resistance, obstructive sleep apnea (OSA), and decreased functional residual capacity (FRC).

The modern understanding of sleep is based on the classification of sleep into stages defined by their electroencephalography (EEG) signatures, but the underlying brain dynamics remain unclear. (nature.com)
Notably, our results reveal key trajectories to switch within and between EEG-based sleep stages, while highlighting the heterogeneities of stage N1 sleep and wakefulness before and after sleep. (nature.com)
On-going brain activity is recorded from a low number of EEG electrodes and typically categorised into wakefulness, rapid-eye movement (REM) sleep and-according to the most recent set of guidelines-three stages of non-REM (NREM) sleep (N1-N3) 2 . (nature.com)
Indeed, PSG-defined sleep stages were originally devised from EEG as surrogate markers of arousal thresholds, yet over time many have come to see them as a more or less exhaustive set of intrinsic canonical states that cover the full repertoire of brain activity during sleep. (nature.com)
Yet, studies that have applied these promising tools to investigate large-scale brain activity of sleep have commonly relied upon PSG in a strict sense, thus regressing PSG stages onto functional brain data. (nature.com)
CPAP was maintained at the therapeutic level during all other stages of sleep. (psychcentral.com)
[11] The first of these stems from the understanding that sleep paralysis is a parasomnia resulting from dysfunctional overlap of the REM and waking stages of sleep. (wikipedia.org)
For example, the brain tries to protect certain types of sleep-in particular the deeper, restorative stages. (sharecare.com)
The trouble with having shortened periods of sleep is that we don't really get into deeper stages right off the bat, so that's where the brain changes. (sharecare.com)
If you go long enough with low-levels of sleep deprivation, the brain actually starts trying to increase slow wave and REM stages earlier and earlier in the night to try to recapture them. (sharecare.com)
NREM sleep consists of 3 stages (N1 to N3) in increasing depth of sleep. (msdmanuals.com)
Slow, rolling eye movements, which characterize quiet wakefulness and early stage N1 sleep, disappear in deeper sleep stages. (msdmanuals.com)
These EEG tracings show characteristic theta waves, sleep spindles, and K complexes during stages 1 (N1), 2 (N2), and 3 (N3) NREM sleep. (msdmanuals.com)
It tends to occur in several stages of sleep (Goyal et al . (bvsalud.org)
NREM sleep has 4 stages, ranging from very light sleep (stage 1) to very deep, restorative sleep (stages 3 and 4). (cdc.gov)
In all stages of NREM sleep, people move in bed, repositioning themselves, often without awakening, but there is very little dreaming. (cdc.gov)

In patients with multiple system atrophy, REM sleep motor dysfunction is a common polysomnographic finding which is otherwise overlooked, and sleep talk may be its early clinical manifestation. (bmj.com)

(psychiatrictimes.com)
At a more molar level, sleep promotes subsequent wakefulness. (psychiatrictimes.com)
Because so many of us routinely reduce our sleep, we have created a new societal standard for wakefulness that is suboptimal. (psychiatrictimes.com)
It is not uncommon to hear people attribute their sleepiness and even uncontrolled sleep attacks to a boring or sedentary activity-not appreciating that their own inherent biological drive for sleep overwhelms wakefulness when stimulation or compensatory effort are no longer enough. (psychiatrictimes.com)
In contrast, wakefulness following satiation of sleep drive is effortless and requires no stimulation. (psychiatrictimes.com)
The neurobiology for wakefulness and the neurobiology for sleep can be thought of as being in opposition [Edgar et al. (psychiatrictimes.com)

Do You Know the Signs of Sleep Deprivation? (sharecare.com)
Sleep deprivation is a broad term to describe someone not getting an adequate amount of sleep," explains Brian Mieczkowski, DO, a pulmonary and sleep medicine physician at the Research Medical Center in Kansas City, Missouri. (sharecare.com)
While grogginess may not seem like that big of a health concern, behind the scenes, sleep deprivation is having a serious effect. (sharecare.com)
Furthermore, "we try to accommodate for the trouble caused by sleep deprivation with caffeine and energy drinks that keep you awake, despite your body saying that you need to sleep," he says. (sharecare.com)
Acute sleep deprivation is defined as no sleep, or curtailed sleep, for one or two nights. (sharecare.com)
They have low-levels of chronic sleep deprivation, perhaps only getting five hours each night, due to busyness or insomnia , which is the inability to fall-or stay-asleep. (sharecare.com)
We know from many studies that in people with sleep deprivation, reaction time dramatically decreases," Mieczkowski explains. (sharecare.com)

Is nocturnal epilepsy cause of disturbed quality of sleep and elevated daytime sleepiness? (nel.edu)
Authors evaluated quality of sleep and daytime vigilance in patients with nocturnal epilepsy and compared it to those with daytime epilepsy. (nel.edu)
Patients with neuromuscular disease with nocturnal hypoventilation are likely to deteriorate with the development of daytime hypercapnia and/or progressive symptoms within 2 years and may benefit from the introduction of nocturnal NIV before daytime hypercapnia ensues. (bmj.com)
Application of nocturnal NIV when these individuals become hypercapnic during the day prolongs survival, 1, 2 improves nocturnal and diurnal blood gas tensions, nomalises sleep patterns, 3 and enhances health related quality of life. (bmj.com)
2 Conversely, preventive use of NIV in patients with asymptomatic Duchenne muscular dystrophy before the development of nocturnal or diurnal ventilatory insufficiency in one randomised trial 4 did not improve survival or prevent deterioration in pulmonary function, and was poorly tolerated. (bmj.com)
however, some patients experience uncontrolled respiratory decompensation or are markedly symptomatic from nocturnal hypoventilation before the development of diurnal ventilatory failure. (bmj.com)

A new study by the same group uses SPECT and transcranial ultrasound neuroimaging techniques to identify those patients at greatest risk of developing neurodegenerative disease. (sciencedaily.com)
