I am starting a thread about Professor Ric Arseneau because I have come across some information about him that is concerning. I understand he gave an online presentation to people with ME/CFS, FM and related conditions. Here's a link to the slides from the presentation: bit.ly/ffdec2021 The slides are mostly links to material we will find familiar, but the particular selection of hypotheses, research and treatments included in a presentation aimed at patients and their families and friends is concerning. Topics emphasised include childhood trauma among triggering factors, and central sensitisation and the stress/HPA axis theories as perpetuating factors. There are extracts from assorted research papers which give the presentation the appearance of being strongly science based, but it all leads up to a treatment section at the end that includes the minimally evidenced drugs currently being researched and or prescribed like LDN, Aripiprazole and Cortene, as well as vagal stimulation. But the key to the whole talk seems to be a strong emphasis in the treatment section at the end on LP-like quackery, specifically the Gupta program, Neuroplastics, the Dynamic Neural Retraining System, and several pages about a McMaster University presentation from 2019 called 'Neuroplasticity based treatment for fibromylagia, chronic fatigue and multiple chemical sensitivity: feasibility and outcomes'. This appears to be an unpublished study, for which some data is given. I understand than Professor Arseneau himself charges thousands of dollars to treat individuals privately using the McMaster program. It seems quackery is alive and thriving in Canada.
