SLEEP DISORDERS

Objectives To gain an understanding of: • What is sleep? • Stages of sleep • NREM (non-REM) and REM (rapid eye movements) sleep • The concept of RAS (reticular activating system) • Identified systems within RAS • Homeostatic drive and circadian rhythms • What makes you “fall” asleep?

Russell Foster, Debra Skene and Stafford Lightman discuss the science of sleep. Why do we need sleep and what are the physiological processes driving our circadian rhythm? When is our circadian clock disrupted and how does this affect our health? Cognitive neuroscientist Vincent Walsh chairs the debate. Subscribe for regular science videos: http://bit.ly/RiSubscRibe The science behind sleeplessness can help us understand our rhythms so we can live better and healthier lives. While hormones, such a melatonin, play a role in driving our circadian clock, the amount of sleep we get and our sleep cycles also affect our hormonal release patterns, with far-reaching implications on our health. Cognitive neuroscientist Vincent Walsh chairs a discussion with a panel of experts who specialise in circadian rhythms. They explore how light detection plays a role in our sleep-wake cycles, how hormone release is regulated and the implications of changes to our circadian clock and sleeplessness over time. This event was supported by British Psychological Society and Society for Endocrinology. Russell Foster is Professor of Circadian Neuroscience at the University of Oxford. The research interests of his group range across visual neuroscience, circadian rhythms and sleep.

She leads the research group 'Sleep, Chronobiology and Addiction' and her research focusses on links between human circadian clocks, sleep and metabolism in health, circadian disorders and metabolic diseases. Stafford Lightman is Professor of Medicine at Bristol University. Researching the mechanisms of stress-related disease, his research has particularly looked at how neuroendocrine rhythms signal to other tissues in the body.

UCLA neurologist Alon Avidan, MD, discusses common sleep disorders, including insomnia, hypersomnia, sleep apnea, restless legs, circadian rhythm disorders, narcolepsy, and parasomnia. He also explores the consequences of poor sleep and ways to help you achieve a healthy night’s sleep. Watch more webinars at https://www.uclahealth.org/uclamdchat
