A DSPD subject exhibited an average sleep onset latency twice that of the 3 control subjects and almost twice the amount of wakefulness after sleep onset (WASO) as control subjects, resulting in significantly poorer sleep efficiency. Also, the temporal distribution of slow wave sleep was significantly altered in the DSPD subject.
NREM parasomnias are arousal disorders that occur during stage 3 (or 4 by the R&K standardization) of NREM sleep—also known as slow wave sleep (SWS). They are caused by a physiological activation in which the patient's brain exits from SWS and is caught in between a sleeping and waking state.
OSA is a serious medical condition with systemic effects; patients with untreated OSA have a greater mortality risk from cardiovascular disease than those undergoing appropriate treatment. [37] Other complications include hypertension, congestive heart failure, atrial fibrillation, coronary artery disease, stroke, and type 2 diabetes. [37]
Loss of slow-wave sleep, also known as deep sleep, has been linked with increased risk of developing dementia. Getting less slow-wave sleep as you age may increase your risk of dementia, study ...
Deep sleep refers to slow-wave sleep — a stage in the sleep cycle when brain waves slow down. Getting enough deep sleep is crucial for numerous bodily functions. But how to increase deep sleep ...
Parasomnias like sleepwalking and talking typically occur during the first part of an individual's sleep cycle, the first slow wave of sleep [63] During the first slow wave of sleep period of the sleep cycle the mind and body slow down causing one to feel drowsy and relaxed. At this stage it is the easiest to wake up, therefore many children do ...
Stress, health conditions, and even uncomfortable sleep environments (think: a stuffy room, lumpy mattress, or city noise) can all contribute to this nightly battle. Sleep noises are rhythmic ...
While slow waves and sleep spindles are present in stages 2 and 3, stage 2 sleep is characterized by a higher prevalence of spindles, while slow waves dominate the EEG during stage 3. [22] [21] Slow-wave sleep is an active phenomenon probably brought about by the activation of serotonergic neurons of the raphe system. [23]
