Abstract
The second part of the manuscript on pediatric sleep medicine deals with the most frequent parasomnias, sleep disordered breathing and narcolepsy. Parasomnias (somnambulism, sleep terrors, sleep enuresis) have tendency to disappear with age.
While nocturnal enuresis represents mostly social problem, somnambulism is connected with increased risk of injury. Obstructive sleep apnea is a type of sleep disordered breathing prevailing in preschool age.
Apart from negative influence on cognitive functions and behavior it has an impact on cardiovascular system and metabolic parameters. A significant risk factor for obstructive sleep apnea is obesity.
Narcolepsy is a rare chronic disorder with symptoms of excessive daytime sleepiness. Signs of narcolepsy can be inconspicious - school failure, poor concentration, behavioral changes.
Diagnosis of sleep disordered breathing and narcolepsy is based on nocturnal polysomnography.
