LIRA, David  e  CUSTODIO, Nilton. Sleep disorders and their complex relationship with cognitive functions. Rev Neuropsiquiatr [online]. 2018, vol.81, n.1, pp.20-28. ISSN 0034-8597.  http://dx.doi.org/https://doi.org/10.20453/rnp.v81i1.3270.

Sleep is a physiological need in humans that plays multiple roles and presents special characteristics that vary with age periods and environmental factors. It is regulated by brain neurotransmitters and through intrinsic biological rhythms of periodic nature that manifest themselves with 24-hour intervals (circadian rhythm), which regulate the sleep-wake cycle. Currently, exposure to artificial light at night, as well as the accelerated rhythm of modern life, contribute to the increased prevalence of sleep disorders, which could affect cognitive functions through various physiopathological mechanisms at different age periods, particularly among small children and older adults. It is necessary studies to conduct research studies that assist in determining sleep factors that increase cognitive impairment, as well as preventive measures that can be adequately implemented.
