Sleep disturbances and their impact on medical disease and morbidity.

Ohayon MM, Int J Sleep Wakefulness Prim Care. 2008; (1): 141-145

In general population, insomnia complaints are reported by near the third of the population, it translated into a diagnosis of insomnia for only 6% to 15% of the population. Similarly, excessive daytime sleepiness is reported by about 20% of the population but only 2% have a diagnosis of hypersomnia, narcolepsy or insufficient sleep syndrome. In the overwhelming majority of these individuals, sleep disturbances rarely occur alone and are frequently caused or associated with various medical or neurological diseases, psychiatric disorders and environmental factors. It is therefore imperative to diagnose these co-morbid conditions as part of an appropriate planning of the treatment.
