Sleep is a biological phenomenon that remains a puzzle as to why sleep is needed by humans and other species of animals. One theory is the "synaptic homeostasis hypothesis" which postulates that sleep is required to reset and decrease overstimulated synaptic connectivity in the brain. Adequate sleep is essential to health, improves a sense of well being, cognitive agility, and life span. Disorders of sleep include Excessive Daytime Sleepiness, Insomnia, Circadian Rhythm Disorders, REM and non-REM parasomnias.
Sleep deprivation may result in changes in mood (irritability, depression), decrease of consistent performance and weight gain. Sleep apnea, often accompanied by snoring, may affect children as well as adults. Sleep apnea increases the manisfestations of other significant medical and psychiatric disorders such as strokes, hypertension, diabetes, headaches, depression and motor vehicle accidents.
A careful clinical history and physical examination along with a sleep lab study and monitoring (polysomnography) EEG, EOG (eye movements), Nasal respiration (Pressure, Carbon dioxide, Temperature), Submental EMG, EKG, chest and abdominal belts. The hypnogram normally shows waking state, REM sleep, and Stages I, II, III and IV sleep through a monitored sleep period. If you have questions about sleep disorders, please contact Byron L.
