What Are the Causes of Sudden Insomnia?
There are a few possible causes of sudden insomnia. Several sleep disorders, including narcolepsy and sleep apnea, can cause sudden episodes of insomnia that can last for hours or even days. Other causes include anxiety, depression, and stress. If you have ever had any of these conditions, it is worth getting checked out by a doctor to rule out the possibility of a more serious sleep disorder.
How Is Sudden Insomnia Diagnosed?
There is no one definitive way to diagnose sudden insomnia. Symptoms of the disorder can be difficult to distinguish from those caused by other sleep problems, such as sleep apnea or restless leg syndrome. A doctor may ask you about your sleep habits and performance, and perform a variety of tests to assess whether you have a disorder.
