The 20 Best Idiopathic Hypersomnia Doctors Near Me in Nashville, TN

Idiopathic hypersomnia (IH) is a neurological sleep disorder that can affect many aspects of a person's life. Symptoms often begin between adolescence and young adulthood and develop over weeks to months. People with IH have a hard time staying awake and alert during the day (chronic excessive daytime sleepiness). They may fall asleep unintentionally or at inappropriate times, interfering with daily functioning. They may also have difficulty waking up from nighttime sleep or daytime naps. Sleeping longer at night does not appear to improve daytime sleepiness. The cause of IH is not known. Some people with IH have other family members with a sleep disorder such as IH or narcolepsy.
