Visiting Scientist Professor Bill Schwartz will join us in June 2019 – further detail on the dates of his lectures and classes for undergraduates and postgraduates coming soon!

Laboratory description

Over the last few years we have studied the pathophysiology and the management of circadian and sleep disorders in patients with liver disease. We are currently using our experience with the liver as a model, and applying it to other, specific areas of medicine both in the outpatient and inpatient setting.

We have utilised/developed:
– Standard and patient-directed, specific questionnaires
– Actigraphy
– Wake and sleep EEG
– Continuous, high-resolution temperature monitoring
– Models for the induction or simulation of hepatic and other metabolic encephalopaties.

Additional Descriptors, Keywords

sleep, genetics of sleep, pharmacology of sleep, parasomnias, narcolepsy, hypersomnias, apnoea, history of sleep, epilepsy
