Hypersomnia is a neurological disorder of excessive time spent sleeping or excessive sleepiness. It can have many possible causes (such as seasonal affective disorder) and can cause distress and problems with functioning.[1] In the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), hypersomnolence, of which there are several subtypes, appears under sleep-wake disorders.[2]
Hypersomnia is a pathological state characterized by a lack of alertness during the waking episodes of the day.[3] It is not to be confused with fatigue, which is a normal physiological state.[4] Daytime sleepiness appears most commonly during situations where little interaction is needed.[5]
Since hypersomnia impairs patients' attention levels (wakefulness), quality of life may be impacted as well.[6] This is especially true for people whose jobs request high levels of attention, such as in the healthcare field.[6]
This is not to be confused with clinophilia, a sleep disorder where a person intentionally refuses to get out of bed, regardless of a disease or not.
