Circadian rhythms, melatonin and depression.
The master biological clock situated in the suprachiasmatic nuclei of the anterior hypothalamus plays a vital role in orchestrating the circadian rhythms of multiple biological processes. Increasing evidence points to a role of the biological clock in the development of depression. In seasonal depression and in bipolar disorders it seems likely that the circadian system plays a vital role in th...
متن کاملCircadian rhythms and treatment implications in depression.
In humans almost all physiological and behavioural functions occur on a rhythmic basis. Therefore the possibility that delays, advances or desynchronizations of circadian rhythms may play a role in the pathophysiology of psychiatric disorders is an interesting field of research. In particular mood disorders such as seasonal affective disorder and major depression have been linked to circadian r...
متن کاملCircadian rhythms: strong evidence on how to approach depression
It is widely accepted that mood disorders are related to biological rhythm abnormalities. It has been proved that this happens at least in a significant proportion of patients which profit from chronotherapeutic interventions. Rhythm abnormalities in mood disorders include among others diurnal mood variation, elevated nocturnal body temperature, lower nocturnal TSH, overall increased cortisol s...
متن کاملHypoxic depression of circadian rhythms in adult rats.
Because the circadian rhythms of oxygen consumption (VO(2)) and body temperature (T(b)) could be contributed to by differences in thermogenesis and because hypoxia depresses thermogenesis in its various forms, we tested the hypothesis that hypoxia blunts the normal daily oscillations in VO(2) and T(b). Adult rats were instrumented for measurements of T(b) and activity by telemetry; VO(2) was me...
متن کاملCircadian rhythms.
1997 marks the 25th anniversary of the discovery of the master circadian pacemaker in mammals in the hypothalamic suprachiasmatic nucleus. Remarkable progress has been made over the last 25 years in elucidating the physiological mechanisms involved in the entrainment, generation and expression of circadian rhythms at the cellular and systems levels. The recent discovery and cloning of the first...
