Primary insomnia is a sleep disorder not attributable to a medical, psychiatric, or environmental cause. Insomnia can be grouped into primary and secondary, or comorbid, insomnia. Many of its symptoms are easily recognizable, including excessive daytime sleepiness frustration or worry about sleep problems with attention, concentration, or memory extreme mood changes or irritability lack of energy or motivation poor performance at school or work and tension headaches or stomach aches. Insomnia, one of the six types of dyssomnia, affects 21–37% of the adult population. Long-term total sleep deprivation has caused death in lab animals. A complete absence of sleep over a long period is not frequent in humans (unless they suffer from fatal insomnia or specific issues caused by surgery) it appears that brief microsleeps cannot be avoided. įew studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. However, in a subset of cases, sleep deprivation can paradoxically lead to increased energy and alertness and enhanced mood although its long-term consequences have never been evaluated, sleep deprivation has even been used as a treatment for depression.

Ī chronic sleep-restricted state adversely affects the brain and cognitive function. Sleep deprived individuals are able to fall asleep rapidly when allowed but those suffering from insomnia have difficulty falling asleep.

Although both chronic sleep deficiency and insomnia share decreased quantity and/or quality of sleep as well as impaired function, their difference lies on the ability to fall asleep. Chronic sleep deficiency is often confused with the term insomnia. Chronic sleep deprivation means when an individual routinely sleeps less than an optimal amount for ideal functioning. It can be either chronic or acute and may vary widely in severity.Īcute sleep deprivation is when an individual sleeps less than usual or does not sleep at all for a short period of time – usually lasting one to two days. Sleep deprivation, also known as sleep insufficiency or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health.
