From Wikipedia, the free encyclopedia Advanced sleep phase disorder (ASPD), also known as the advanced sleep-phase type (ASPT) of circadian rhythm sleep disorder or advanced sleep phase syndrome (ASPS), is a condition in which patients feel very sleepy and go to bed early in the evening (e.g. 6:00–8:00 p.m.) and wake up very early in the…
Irregular Sleep
From Wikipedia, the free encyclopedia Irregular sleep–wake rhythm is a rare form of circadian rhythm sleep disorder. It is characterized by numerous naps throughout the 24-hour period, no main nighttime sleep episode and irregularity from day to day.[1] Sufferers have no pattern of when they are awake or asleep, may have poor quality sleep, and…
Delayed Sleep
From Wikipedia, the free encyclopedia Delayed sleep phase disorder (DSPD), more often known as delayed sleep phase syndrome and also as delayed sleep-wake phase disorder, is a chronic dysregulation of a person’s circadian rhythm (biological clock), compared to the general population and relative to societal norms. The disorder affects the timing of sleep, peak period…
Circadian Rhythm Sleep Disorder
Circadian Rhythm Sleep Disorder is a disruption in an individual’s internal body clock. These neurological disorders involve a cycle of being asleep and awake that is ‘out of sync’ (or out of step) with the day-night cycles. What are the other Names for this Condition? (Also known as/Synonyms) Circadian Sleep Disorder (CSD) Delayed Sleep Phase…
Circadian Rhythm Sleep Disorder
From Wikipedia, the free encyclopedia Circadian rhythm sleep disorders (CRSD) are a family of sleep disorders affecting (among other bodily processes) the timing of sleep. People with circadian rhythm sleep disorders are unable to go to sleep and awaken at the times commonly required for work and school as well as social needs. They are…
Strengthening Circadian Rhythms through Mapping of Neural Networks
by Rachael Herman Most people feel groggy after hopping time zones. This is the body’s response to the temporary mismatch between the new local time and the body’s natural 24-hour circadian rhythm. This rhythm in mammals is governed by the suprachiasmatic nucleus (SCN) on a hormonal and neuronal level. The SCN is a small region…
Shifts in Sleep-Wake Cycles Affect Women More than Men
by Rachael Herman The Surrey Sleep Research Center at the University of Surrey has performed a new study that shows shifts in the sleep-wake cycles (circadian rhythm) has a greater impact on women than it does on men. This study was published in the journal, Proceedings of the National Academy of Sciences (PNAS). The study…
New Research on How We Fall Asleep and Wake up
by Rachael Herman There are millions of people who have trouble with transitioning from an asleep to an awake state. Many find it difficult to fall and stay asleep throughout the night, as well as stay awake and alert throughout the day. The neurobiological mechanics of our sleep-wake cycle, or circadian rhythm, has remained largely…
Parkinson’s Disease Worsened by Altered Circadian Rhythm
by Rachael Herman New research from the Lewis Katz School of Medicine at Temple University (LKSOM) suggests that irregular sleep-wake cycles and chronic insomnia may be risk factors of Parkinson’s disease. In this animal model study, circadian rhythm disturbances before the onset of Parkinson’s disease significantly worsened learning and motor deficits brought on by this…
Risk of Metabolic Syndrome due to Daytime Sleepiness and Long Naps
by Rachael Herman A study scheduled to be reviewed at the 65th Annual Scientific Session for the American College of Cardiology reports that long naps and daytime sleepiness put an individual at higher risk of developing metabolic syndrome. Metabolic syndrome is characterized by a collection of conditions that put an individual at risk for developing…
