COVID-19: Read the Letter to the members


We are looking for the research priorities of clinicians who care for people living with Obstructive Sleep Apnea. We want to give you a louder voice in research. If you are a clinician caring for patients with obstructive sleep apnea, we would appreciate if you could take a few minutes to complete the survey and/or send it to clinicians you know. Thank you!

The PERFORM center (Montreal) invites you to a colloquium entitled Health Consequences of Circadian and Sleep Disruption presented on February 12 by Dr. Kenneth Wright. Click here for details.

The University of Saskatchewan, working with the Respiratory Research Center and the Saskatchewan Centre for Patient-Oriented Research, has engaged James Lind Alliance (UK) to establish priorities in Patient-Oriented Research. We are pleased to announce they have chosen OSA as the first project at Dr. Robert Skomro’s site. This is the first such initiative in Canada. Dr. Skomro would like to reach out to sites that have Patient-Oriented Research Centers to see if there would be opportunities for collaboration.  If you would like to have more information on this initiative, please go to or contact Dr. Robert Skomro at

The Center for Studies in Behavioral Neurobiology and the PERFORM Centre are pleased to invite you to their mini symposium on Sleep, Brain Plasticity and Cognition on Friday, September 27, 2019 (09:00 - 12:00). Click here for the official announcement.
