Temporary Insomnia, Chronic Insomnia, Evaluation And Treatment

The term insomnia applies to a variety of conditions involving lack of sleep, difficulty falling asleep, and disrupted or insufficiently restful sleeping patterns. Not only the quantity but the quality of sleep is at issue for those who research insomnia and its effects on behavior and productivity during waking hours. Primary insomnias include chronic and temporary sleeplessness. Secondary insomnias are defined as unusual sleeping patterns like sleepwalking or nocturnal eating, "night terrors" or nightmares, and respiratory movement or nervous disorders such as the "restless leg" syndrome.
