Including such conditions as Primary Insomnia, chronic difficulties sleeping with no apparant symptoms, bruxism, circadian rhythm disorders, Non-24 Hour Sleep-Wake Syndrome, Hypopnea Syndrome, excessive daytime sleepiness, sudden weaknesses in motor muscles, cataplexy, sudden involuntary arm and leg movements during sleep, jet lag, sleep apnea, sleep paralysis, nocturia, the fear of sleep known as somniphobia, narcolepsy, Kleine-Levin Syndrome, Exploding Head Syndrome characterized by hearing non-existing loud noises that awaken the patient, various psychoses, and sleeping sickness, many forms of sleep disorders may occur preventing patients from getting rest the body needs to properly function.
Other types of common sleep disorders may include:
Several studies have shown that all children may experience occasional nightmares consisting of images, themes, monsters, animals, ghosts, and bad people posing potential dangers or threats to the child, however, preschoolers, ages three to eight years old, most frequently have these bad dreams due to the facts that their imaginations are extremely creative and this is the age normal fears begin developing in children.
Nightmares may alternate between the two sleep stages, known as non-rapid eye movement and rapid eye movement cycles, that rotate approximately every hour and a half, and typically occur in the middle of the night or in the early morning hours in the REM stages of sleep.
Parasomnia sleep disorders known as night terrors may involve unnatural movements, abnormal behaviors, preceptions, emotions, or dreams that happen while falling asleep, when awaking from sleep, or between sleep stages, and may include loud screams, panic attacks, confused states, and the inabilities of comforting the child experiencing the terrors.
REM Sleep Behavior Disorders:
Possibly attributable to such things as the side effects of prescription medications, antidepressants, and neurological problems, Rapid Eye Movement Sleep Disorders, in which muscle atonia, or lost muscle strength is absent, may allow children to act out their nightmares possibly resulting in bruises, injuries, cuts, abrasions, bone fractures, screaming, and motor activities.
Known as slow wave sleep, deep sleep, or Non-Rapid Eye Movement sleep, NREM parasomnias may include such things as confusional arousals, sleep walking, night terrors, teeth grindings, rhythmic movement disorders, somniloquy, sleep talking, sleep eating, restless leg syndrome, and somnambulisms.
Rapid Eye Movement Sleep:
Physiologically different from other forms of sleep, and consisting of tonic and phasic stages, Rapid Eye Movement sleep occurs between four and five times a night and may be followed by periods of very short light sleep that do not stimulate the body’s motor neurons, muscles that do not move, irregular breathing and heart rates, body temperatures that are not well regulated, rapid eye movements, and sexual organ erections that may last up to three and a half hours long.
Non-REM sleep is generally composed of the three distinct episodes known as Stage One in which slow eye movements, Theta wave movements recorded inside the brain, Alpha wave disappearances, and involuntary mysoclonic twitches called hynic jerks occur, Stage Two that involves no eye movements at all, very rare dreaming, sleep spindle brain activities immediately following muscle twitchings, K-Complex wave forms, easy arousal from sleeping, and Stage Three that includes deep sleep, slow-wave sleep, high amplitude Delta brain waves, less memorable dreams, and the most common occurrences of parasomnias.
