Arousal During Sleep

- The arousal is a partial arousal usually from deep sleep also called slow wave sleep. Most commonly the child transitions from deep sleep to a mixture of very light sleep and/or partial wakefulness.

- Arousal during sleep can result in sleep fragmentation and various physiological effects, impairing cognitive function and raising blood pressure and heart rate. However, the current definition of arousal has limitations in assessing both amplitude ...

The main objective of this investigation was to ascertain whether there are, in the female, periods of sexual excitation or arousal during REM sleep similar to the cycle of penile erections in the male. In a group of 10 subjects, 2135, utilizing a thermoconductance method that gives a measure of vaginal blood flow (VBF), we are able to confirm that females manifest cyclic episodes of vascular engorgement during REMPs equivalent to erections in men.

Obstructive apnea during sleep elevates the set point for efferent sympathetic outflow during wakefulness. Such resetting is attributed to hypoxia-induced upregulation of peripheral chemoreceptor and brain stem sympathetic function. Whether recurrent arousal from sleep also influences daytime ...

These disorders include confusional arousals, somnambulism (sleepwalking), and sleep terrors, and they tend to arise from incomplete arousal from deep sleep, leading to a dissociation between sleep and wake states.

OSA is characterized by intermittent narrowing and collapse of the pharyngeal airway during sleep. These interruptions to breathing cause blood-gas disturbances, are often associated with brief awakening (cortical arousal), and thereby disrupt sleep continuity.

- A confusional arousal is when a sleeping person appears to wake up but their behavior is unusual or strange. The individual may be disoriented, unresponsive, have slow speech or confused thinking.

- The International Classification of Sleep Disorders (3rd edition, text revision) categorizes confusional arousals as a disorder of arousal from NREM sleep. The episodes arise out of sleep and consist of confusion, disorientation, and amnesia for the event.
