adrenal cortex. What factors cause disturbances in this system? - Cortisol has one of the most distinct circadian rhythms in human physiology. This is regulated by the central clock located in the suprachiasmatic nucleus of the hypothalamus. Cortisol acts as a secondary messenger between central and peripheral clocks, hence its importance in the synchronization of body circadian rhythms. Conventional immediate-release hydrocortisone, either at twice- or thrice-daily doses, is not capable of replicating physiological cortisol circadian rhythm and patients with adrenal insufficiency or congenital adrenal hyperplasia still suffer from a poor quality of life and increased mortality. Patients who are deficient in cortisol are known to suffer from adrenal insufficiency. The condition typically presents insidiously and may be easily overlooked. Patients will die if adrenal insufficiency is not diagnosed promptly and treated effectively. Circadian rhythm sleep disorders are caused by desynchronization between internal sleep- wake rhythms and the light-darkness cycle. Patients typically have insomnia, excessive daytime sleepiness, or both, which typically resolve as the bodyclock realigns itself Chan, S., & Debono, M. (2010, June).

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
