Moreover, medical conditions such as stroke, head injury, dementia, lack of sleep, jet lag, various work shifts, older age, particular drugs, lack of exposure to sunlight for longer time, are the situations, which can trigger circadian rhythm sleep disorder.
The diagnosis for circadian rhythm sleep disorder are often challenging and requires consulting with the sleep specialist. Wrist watch device named Actigraph helps to record sleep and wake activity from days to weeks.
Treatment option for circadian rhythm sleep disorder includes lifestyle and behavior therapy, bright light therapy, medications, and chronotherapy.

Furthermore, increasing U.S. FDA approval, announcement of new information or manufacturing capabilities and agreements by market players are expected to boost the circadian rhythm sleep disorder market growth over the forecast period.
For instance, Vanda Pharmaceutical, in December 2020 announced that U.S. Food and Drug Administration (FDA) approved its HETLIOZ capsule and liquid formulations for the diagnosis of children and adults, associated with Smith-Magenis Syndrome (SMS) a development disorder which causes sleep disturbances.
Moreover, in October 2018, Eisai announced that they presented new information for phase II evaluation of Lemborexant, an experimental sleep-wake regulation agent, for the diagnosis of irregular sleep wake rhythm disorder in sufferer patient with mild to moderate Alzheimer’s disease. Alzheimer ’s disease data was presented in 11th Clinical Trials conference in Barcelona, Spain. Including insomnia disorder, Lemborexant is also developed for diagnosis of multiple sleep-wake disorders.
Circadian Rhythm Sleep Disorders Market – Regional Insights
Among regions, North America and Europe are estimated to account for significant market share in the global circadian rhythm sleep disorders market. This is attributed to rising prevalence of chronic diseases (Obesity, Depression, Cardiovascular disease) and geriatric population. For instance, according to the European Commission, 2013 report, total 17% of European Population was above age 65 years. Therefore, rise in geriatric population is expected to drives growth of the circadian rhythm sleep disorders market in European Region. By National Library of Medicine, most common circadian rhythm sleep disorder is delayed sleep phase disorder with an estimated prevalence of 0.17% in the U.S. population and 7–16% prevalence among adolescents.
