University of Groningen ON THE EXPLANATION OF SHORT REM LATENCIES IN DEPRESSION

نویسنده

  • Rutger H. van den Hoofdakker
چکیده

Sleep in depression is characterized by the occurrence of episodes of rapid eye movement (REM) sleep at sleep onset. The empirical foundations of three hypotheses about the origin of this phenomenon are examined: (I) A circadian rhythm hypothesis stating that sleep onset REM episodes (SOREMs) are the result of an abnormal phase-position of the REM sleep production cycle. (2) A REM sleep-slow wave sleep interaction hypothesis that attributes SOREMs to a low non-REM sleep propensity. (3) A circadian amplitude hypothesis, in which a flattening of the circadian arousal cycle is thought to be causally related to SOREMs. None of the hypotheses are found to be supported by firm empirical evidence.

 Background: Sleep is a universal circadian biological rhythm which is seen among all vertebrate and has two separate steps including REM and Non-REM. Total or partial sleep deprivation would lead to cognitive dysfunction. It seems that the cognitive dysfunction following sleep deprivation is resulted from cellular changes in certain area involved in this phenomenon. Regarding the role of ...

Comparing the Effects of Melatonin and Zolpidem on Sleep Quality, Depression, and Anxiety in Patients With Colorectal Cancer Undergoing Chemotherapy

Introduction: Patients with cancer may have many complications involving their psychosomatic systems, such as sleep disturbance, depression, and anxiety. Thus, many research studies were conducted to reduce these complications. Zolpidem, as a short-term non-benzodiazepine treatment of insomnia, and melatonin as a chronobiological function-regulatory hormone, are commonly used for improving slee...

RAPID EYE MOVEMENT SLEEP DEPRIVATION INDUCES ACETYLCHOLINESTERASE A CTIVITY IN THE PREOPTIC AREA OF THE RAT BRAIN

Acetylcholinesterase (AchE) is a large glycoprotein that, aside from its known cholinolytic activity, co-exists with other transmitter systems and possesses other functions. In the present study, the effects of short-term rapid-eye-movement sleep deprivation (REM-SD) on AchE activity in the anterior hypothalamic area have been investigated. Using the flower-pot method, adult male albino ra...
