BERMUDEZ, Jorge. Enfermedad laboral relacionada a trastornos del sueño por alteración del ritmo circadiano (tsrc). a propósito de un caso. Med. leg. Costa Rica [online]. 2014, vol.31, n.1, pp.103-115. ISSN 2215-5287.

Introduction: Biological rhythms adjust to environmental cycles such as light and darkness; most of these rhythms are maintained with a circadian character. The fact to have adapted to a planet with regular features such marked probably printed in the genome of the most primitive organisms so successful that chronobiological mechanisms have remained to the present day. The desynchronization of the sleep-wake rhythm happens in night workers and in turn, may provoke various alterations: Sleep too, biological cellular and molecular level, changes in brain activity, functional alterations of lipid metabolism and daytime sleepiness and carbohydrates, changes in insulin resistance, hormonal-endocrine changes, etc. Objective: To present a rare case report in the literature of occupational disease by TSRC. Case report. This is a 34 year old with circadian rhythm disorder in worker shifts triggered migraine episodes and foci of cerebral ischemia. Outcome: Received treatment for your sleep disorder and anti-migraine treatment, evolution over five years of follow up showed normalization of sleep patterns, migraine attacks gradually decreased in intensity and frequency until complete disappearance. Magnetic resonance imaging (MRI) showed sequelae stable reduction of the ischemic area Conclusions: The literature points to the relationship between circadian rhythm sleep disorders, migraine and cerebrovascular disease. The treatment of the underlying sleep disorder improves headaches, so it is advisable to monitor workers with rotating pattern of work or night work when sleep disturbances associated with migraine, because early treatment may prevent implementation of cerebrovascular permanent sequelae.
