Sleep state misperception is diagnosed when people get enough sleep but inaccurately perceive that their sleep is insufficient.Secondary insomnia, or comorbid insomnia, occurs concurrently with other medical, neurological, psychological and psychiatric conditions. Causation is not necessarily implied.Sleep is known to be cumulative. This means that the fatigue and sleep one lost as a result, for example, staying awake all night, would be carried over to the following day. Not getting enough sleep a couple days cumulatively builds up a deficiency and thats when all the symptoms of sleep deprivation come in. A well rested and healthy individual will generally spend less time in the REM stage of sleep. Studies have shown an inverse relationship between time spent in the REM stage of sleep and subsequent wakefulness during waking hours. Sleep apnea
Sleep apnea is a serious disorder that has symptoms of both insomnia and sleep deprivation, among other symptoms like excessive daytime sleepiness, abrupt awakenings, difficulty concentrating, etc. Obstructive sleep apnea is often caused by collapse of the upper airway during sleep, which reduces airflow to the lungs. Those with sleep apnea may experience symptoms such as awakening gasping or choking, restless sleep, morning headaches, morning confusion or irritability and restlessness. This disorder affects between 1 and 10 percent of Americans. It has many serious health outcomes if untreated. Positive airway pressure therapy using a CPAP (Continuous positive airway pressure), APAP or BPAP devices is considered to be the first line treatment option for sleep apnea.
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.Few studies have compared the effects of acute total sleep deprivation and chronic partial sleep restriction. A complete absence of sleep over a long period is not frequent in humans (unless they have fatal insomnia or specific issues caused by surgery); it appears that brief microsleeps cannot be avoided. Long-term total sleep deprivation has caused death in lab animals. Causes
Insomnia
Insomnia, one of the six types of dyssomnia, affects 21–37% of the adult population. 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 can be grouped into primary and secondary, or comorbid, insomnia.Primary insomnia is a sleep disorder not attributable to a medical, psychiatric, or environmental cause. There are three main types of primary insomnia. These include: psychophysiological, idiopathic insomnia, and sleep state misperception (paradoxical insomnia). Psychophysiological insomnia is anxiety-induced. Idiopathic insomnia generally begins in childhood and lasts the rest of a persons life. Its suggested that idiopathic insomnia is a neurochemical problem in a part of the brain that controls the sleep-wake cycle, resulting in either under-active sleep signals or over-active wake signals.
