Disorders of arousal and sleep systems

Show Summary Details

Preview

Sleeping and waking mechanisms operate together as a homogeneous functional unit, the final output of which determines the level of arousal. Thus, disorders of one mechanism inevitably tend to affect others: anxiety is accompanied by insomnia; poor night-time sleep is associated with daytime sleepiness. However, for convenience the disorders are divided here into those which are mainly manifested in the waking state (for example anxiety syndromes) and those whose main characteristic is sleep disturbance (for example insomnia and hypersomnia).

Keywords: sleeping mechanism; waking mechanism; sleep disorders; arousal; insomnia; daytime sleepiness; anxiety
