Insomnia, Sleep Disorders

Sleep apnea is a condition characterized by episodes in which breathing stops during sleep. These episodes of stopped breathing usually last for 10 seconds or more, sometimes more than 300 times a night. This condition is potentially life threatening causing significant social and emotional problems, and hampering day to day living. People with sleep apnea will awaken partially as they struggle to breathe, but in the morning will be unaware of any sleep disturbances ever occurring.

Restless leg syndrome is a condition in which your legs experience an unpleasant sensation causing an irresistible urge to move them – often during sleep or when trying to fall asleep or when at rest, either lying or sitting down. By moving the legs, the uncomfortable sensation eases and goes away temporarily. Restless leg syndrome may also occur in the arms. This condition can disrupt sleep routines, most frequently during the evening or early part of the night, making it hard to fall asleep and stay asleep.

Periodic limb movement disorder (PLMD), is a condition in which a person’s legs or arms twitch, cramp or move involuntarily and periodically during sleep. Previously, PLMD was referred to as nocturnal myoclonus - rapid, rhythmic contractions of the muscles often seen in seizures. However, PLMD is not myoclonus.
