Insomnia is one of the most common sleep disorders which affects 30-40 percent of the adult population. The present article provides a combined review on prevalence, categories of insomnia, pathophysiology, role of neurotransmitter on sleep and different types of therapies for insomnia. From this review it was estimated that hormones like melatonin, cortisol, and others produced by the hypothalamic-pituitary-adrenal axis regulate the sleep-wake cycle. Disturbance of this cycle leads to insomnia. Furthermore, Neurotransmitter like GABA-Lglutamic acid, Acetylcholine, Norepinephrine, Dopamine, Serotonin, Steroids, Orexin, and Adenosine plays a major role in sleep regulation. Any alteration or disturbance in the neurotransmitter level affects sleep. It was concluded that Mechanism of action of almost all natural and synthetic derived drugs in regulation of neurotransmitters.

The Impact

Background: Vitamin D exerts multiple pleiotropic effects beyond its role in calcium-phosphate metabolism. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in the regulatory mechanisms of the sleep-wake cycle. Objective: The study aimed to explore and summarize the current knowledge about the role of vitamin D in sleep regulation and the impact of vitamin D deficiency on sleep disorders. Methods: The main regulatory mechanisms of vitamin D on sleep are explained in this study. The literature was scanned to identify clinical trials and correlation studies showing an association between vitamin D deficiency and sleep disorders. Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep. Furthermore, vitamin D can affect sleep indirectly through non-specific pain disorders, correlated with alterations in sleep quality, such as restless legs syndrome and obstructive sleep apnea syndrome. Conclusions: : Vitamin D has both a direct and an indirect role in the regulation of sleep. Although vitamin D deficiency has been associated to sleep disorders, there is still scant evidence to concretely support the role of vitamin D supplementation in the prevention or treatment of sleep disturbances; indeed, more intervention studies are needed to better clarify these aspects.

Pituitary Adrenal Axis

Blood pressure regulation may be mediated by corticotropin-releasing factor and/or by adrenocorticotropic hormone, by adrenocortical steroids, or by adrenomedullary catecholamines. The interaction between these factors is complex. Catecholamines and central actions of the neuropeptides may be involved in rapid hemodynamic responses to "stress". In contrast, adrenocortical steroids are probably more important in longer-term adaptations of the circulation to prolonged stress.
