Polysomnographic Evaluation
Clearest and most comprehensive picture your sleep habits can be determined by this. The patient spends one or more nights sleeping in a sleep laboratory, being monitored on a number of measure that inclue respiration and oxygen desaturation, leg movements, brain wave activity, eye movements, muscle movements, and hear activity.
Sleep Efficiency
The percentage of time actually spent asleep, not just laying in bed trying to sleep. Calculated by the amount of time actually spent asleep by the amount of time spent in bed. Percentage not neccessarily indicative of problems, but rather how they react to their percentage.
Afterbeing awake for around forty hours, a person begins this, which last several seconds or longer.

A degenerative brain disorder which leads to total lack of sleep, even microsleep, that eventually leads to death.

Breathing Related Sleep Disorders
People whose breathing is interrupted during their sleep experience numerous brief arousals throughout the night and do not feel rested even after eight or nine hours asleep.
Breathing related sleep disorder marked by very labored breathing during sleep
Obstructive Sleep Apnea
Occurs when airflow stops despite despite continued activity by the respritory system.
Central Sleep Apnea
Involves the complete cessation of respiratory activity for brief periods of time and is often associated with certain central nervous system disorders such as cerebral vascular disease, head trauma, and degenerative disorders.
Circadian Rhythm Sleep Disorder
Characterized by disturbed sleep brought on by the brain's inability to synchronize its sleep patterns with the current patterns of day and night. Includes Jet lag type, shift work type, delayed phase type. All associated with personality disorders.
Suprachiasmatic Nucleus
Part within the hypothalamus that is considered our "biological clock". Connected to it is the pathway that comes from our eyes. The light we see in the morning and the decreasing light at night signal the brain to reset the biological clock.
