A comprehensive evaluation of the human metabolome in sleep deprivation in 2014 found that 27 metabolites are increased after 24 waking hours and suggested serotonin, tryptophan, and taurine may contribute to the antidepressive effect.The incidence of relapse can be decreased by combining sleep deprivation with medication or a combination of light therapy and phase advance (going to bed substantially earlier than ones normal time). Many tricyclic antidepressants suppress REM sleep, providing an additional evidence for a link between mood and sleep. Similarly, tranylcypromine has been shown to completely suppress REM sleep at adequate doses. Treating insomnia
Sleep deprivation can be implemented for a short period of time in the treatment of insomnia. Some common sleep disorders have been shown to respond to cognitive behavioral therapy for insomnia. Cognitive behavioral therapy for insomnia is a multicomponent process that is composed of stimulus control therapy, sleep restriction therapy (SRT), and sleep hygiene therapy. One of the components is a controlled regime of "sleep restriction" in order to restore the homeostatic drive to sleep and encourage normal "sleep efficiency". Stimulus control therapy is intended to limit behaviors intended to condition the body to sleep while in bed. The main goal of stimulus control and sleep restriction therapy is to create an association between bed and sleep. Although sleep restriction therapy shows efficacy when applied as an element of cognitive-behavioral therapy, its efficacy is yet to be proven when used alone. Sleep Hygiene therapy is intended to help patients develop and maintain good sleeping habits.
Such crystals deposited in joints later in the disease may produce gout-like arthritis, with swelling and tenderness. The overproduction of uric acid is present at birth, but may not be recognized by routine clinical laboratory testing methods. The serum uric acid concentration is often normal, as the excess purines are promptly eliminated in the urine. The crystals usually appear as an orange grainy material, or they may coalesce to form either multiple tiny stones or distinct large stones that are difficult to pass. The stones, or calculi, usually cause hematuria (blood in the urine) and increase the risk of urinary tract infection. Some affected people have kidney damage due to such kidney stones. Stones may be the presenting feature of the disease, but can go undetected for months or even years. Nervous system impairment
The periods before and surrounding birth are typically normal in individuals with LNS. The most common presenting features are abnormally decreased muscle tone (hypotonia) and developmental delay, which are evident by three to six months of age. Affected individuals are late in sitting up, while most never crawl or walk. Lack of speech is also a very common trait associated with LNS.Irritability is most often noticed along with the first signs of nervous system impairment. Within the first few years of life, extrapyramidal involvement causes abnormal involuntary muscle contractions such as loss of motor control (dystonia), writhing motions (choreoathetosis), and arching of the spine (opisthotonus). Signs of pyramidal system involvement, including spasticity, overactive reflexes (hyperreflexia) and extensor plantar reflexes, also occur.
