Excessive sleepiness can also be called Hypersomnolence. Most cases of excessive sleepiness are related to insufficient or interrupted sleep, due to lifestyle, work/family roles or poor sleep habits but some people’s extreme tiredness and sleepiness cannot be relieved even after sleep. When the excessive sleepiness is not relieved by sleep it could be a Disorder of Hypersomnolence. Disorders of Hypersomnolence can include Narcolepsy Type 1 and Type 2, Idiopathic Hypersomnia, or Klein-Levin Syndrome. Hypersomnolence is debilitating and challenging and can reduce quality of life and lead to other health conditions.
