In general, transient insomnia resolves when the underlying trigger is removed or corrected. Most people seek medical attention when their insomnia becomes chronic.
The main focus of treatment for insomnia should be directed towards finding the cause. Once a cause is identified, it is important to manage and control the underlying problem, as this alone may eliminate the insomnia all together. Treating the symptoms of insomnia without addressing the main cause is rarely successful. In the majority of cases, chronic insomnia can be cured if its medical or psychiatric causes are evaluated and treated properly.
