This is the second volume of the Research Topic: Complex Relationship Between Sleep, Rhythms, and Mood Disorder the first volume can be viewed
here.
Sleep is a physiological process that affects all aspects of everyday function, one of the key aspects being mood. The relationship between the two is bidirectional, in effect generating a feedback loop often responsible for a quick, interchangeable degradation of both aspects one after the other. Moreover, both processes are related to each other through the rhythmical changes of both states, either in a daily manner or across longer periods of time such as seasons. Finally, the close relationship might not only be based on observational rhythmicity but also on the molecular regulation of sleep and mood through the internal circadian clock.
This Research Topic aims to disentangle the complex relationship between sleep, circadian rhythms, and mood disorders. It aims at exploring factors involved in this complicated and interchangeable association, including seasonality, molecular regulation, diagnosis, and possible treatment.
We welcome studies (e.g. reviews, original research, metanalyses) on, but not limited to, the following topics:
- clinical and molecular interaction between sleep and mood
- regulation and disturbance of sleep in mood disorders
- regulation and disturbance of mood in sleep disorders
- circadian rhythm as a regulation of mood disorders
- circadian clock disruption in sleep disorders
- circadian clock dysregulation in somatic diseases
- disruption of mood/sleep in somatic diseases
