The hypothalamus, a peanut-sized structure deep inside the brain, contains groups of nerve cells that act as control centers affecting sleep and arousal.

Does sleep apnea cause arousal?

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.

What is PLMS arousal index?

Periodic limb movements with associated electrocortical arousals were also calculated during sleep, generating the periodic limb movement arousal index. Arousals were defined as a 3- to 15-second increase in electroencephalogram activity occurring within <0.5 seconds of the PLM event.

What is the rarest sleep disorder?

Kleine-Levin syndrome is an extremely rare disorder characterized by the need for excessive amounts of sleep (hypersomnolence), excessive eating (compulsive hyperphagia), and behavioral abnormalities.
