Insomnia

Idiopathic, which means "primary," insomnia develops in childhood and persists throughout a person's lifetime. Its true cause is a mystery, though people who exhibit this chronic sleeplessness often suffer from particular brain dysfunctions as well; dyslexia for example. These disorders may share a root cause with idiopathic insomnia, but more studies will have to be commissioned before any theories may be formed. Those who suffer from childhood tend to cope more easily than those who develop temporary insomnias. Idiopathic insomniacs are thereby less prone to sleep phobias and other psychological reactions which often accompany transient insomnias.
