Hypersomnia is a type of sleep disorder that results in excessive sleepiness. Patients with this disorder may fall asleep at odd and even dangerous times during the day, such as while driving. It is not uncommon to have other sleep disorders along with hypersomnia. A lack of energy and poor concentration are common signs of hypersomnia. The most well-known hypersomnia is narcolepsy, but there are many others.
Idiopathic hypersomnia is a sleep disorder that presents as an unstoppable need to sleep that may occur multiple times daily. On average, those with idiopathic hypersomnia sleep 12 – 14 hours within a 24-hour timeframe. As the name states, nobody knows the cause of idiopathic hypersomnia.
Kleine-Levin Syndrome is a rare and complex sleep disorder in which recurring episodes of sleeping or excessive sleepiness occurs at inappropriate times in addition to altered behaviors, and a reduced understanding of the world. On average, these episodes can last anywhere from two days to five weeks. Such episodes also tend to happen more than once per year, which can dramatically and negatively impact quality of life.
Insufficient sleep syndrome happens when a person doesn’t get enough sleep, resulting in sleep deprivation. During the daytime, these patients are not alert and feel groggy. However, this is different than choosing to not get enough sleep, such as someone who is charged with around the clock care for another person.
Finally, there is long sleep. A long sleeper routinely sleeps longer than what is considered average for their age. Otherwise, their sleep is high quality and normal. Unfortunately, long sleepers face challenges when they simply don’t have enough waking hours in their day to do everything they need or would like to do.
