Sleep Apnoea - Not uncommon in children, they may snore loudly, drool on the pillow, or have morning headaches. Daytime sleepiness is due to disturbed sleep. These leg twitches are repetitive and may last several seconds. At night they are not recognized by the child but cause fragmented, unrefreshing sleep. They can also occur during the day, leading to a restless child who can't sit still.
Attacks disrupt sleep leading to daytime fatigue and less frequently daytime sleepiness.
Depression - Adolescents may suffer from unrecognized depression which often affects their academic performance. Depressed mood - especially in the morning, daytime sleepiness, lethargy, loss of appetite, poor concentration and irritability may also be signs of depression. Shift Work - Disrupted biological rhythms can affect the quality and duration of sleep. Students who work afternoon or evening shifts can be excessively sleepy during classes, develop mood changes or have cognitive difficulties. Insomnia is characterized by difficulty in falling asleep or staying asleep, early morning wakening and non-restorative sleep.
