Seeking Healthy Volunteers for Research Study – Cambridge UK, 12–15 January

by Newspost

We are looking for healthy control volunteers to match our ME / Long COVID participants for a small pilot study. Participants should be fit and well, do not have ME, Long COVID, or neurological conditions, and are able to go in a scanner.

We are specifically seeking:

✔️Female, aged 18–20

✔️Female, aged 42

✔️Female, aged 50

The study will take place at a research centre in Cambridge, UK between 12th–15th January, and participants will receive free, non-invasive scans (no injections or contrast agents are used). Non-smokers are preferred. Participants will only be needed for a short visit, not a full day. Travel expenses will be reimbursed, though we encourage participants to be within reasonable travel distance of Cambridge.

If you or someone you know is local to the area, fits the criteria, and is happy to attend, please email pr@theperrinclinic.com as soon as possible with: Name, age, contact number & availability.

Although it’s a small study, this work forms part of ongoing research that could play an important role in how ME and Long COVID are better understood, diagnosed, and treated in the future.

Thank you for helping us advance this important research!

NEW RESEARCH SUPPORTS GLYMPHATIC INVOLVEMENT IN ME/CFS

by News

A paper published in International Journal of Molecular Sciences on 27 November 2025 explores “Glymphatic System Dysregulation as a Key Contributor to ME/CFS” – something Dr Perrin first proposed over 35 years ago!

We believe the ME/CFS medical / scientific community will be interested in seriously considering glymphatic dysfunction an important contributor to its pathophysiology. If so, therapeutics that modulate glymphatic function may also benefit patients with ME/CFS.

– Int. J. Mol. Sci. 2025, 26(23), 11524;

While the paper does not reference Dr Perrin’s pioneering work, it is another strong sign that the wider scientific community is continuing to validate the fundamentals of the Perrin Technique™.

Osteo Talk: Podcast Episode with Perrin Technique Practitioners

by Newspost

In celebration of the upcoming Australian Perrin Technique workshops, we’re revisiting this wonderful Osteo Talk podcast from Osteopathy Australia:

“Practice and Potential: The Perrin Technique’s Role in Clinical Care and Careers.”

In this episode, licensed Perrin Technique Practitioners Dr. Amanda Oosterweghel and Dr. Ray Power share how their practices have evolved to meet the growing demand for care among patients with ME/CFS and long COVID.

They discuss:

🧠 How the Perrin Technique has transformed their approach to osteopathic care

🙏 The real difference it’s making for patients’ lives

💡 Why this work continues to inspire both practitioners and patients alike

Amanda also shares a particularly moving patient story – one that brought tears to the eyes of Dr. Raymond Perrin himself when he heard it.

A huge thank you to Osteopathy Australia, Amanda, and Ray for highlighting both the practical and human side of the Perrin Technique by sharing their insights and experiences on the podcast.

THROUGH THE LOOKING GLASS: A TRIUMPH IN PRINT AND PRACTICE

by Newspost

The Academy of Nutritional Medicine (AONM) featured a glowing review of Dr. Ray Perrin’s latest book, Through the Looking Glass: Diagnosing and Treating Long COVID Using the Perrin Technique, in their November newsletter. Described as a “tour-de-force”, the review shares how the book combines cutting-edge research with over three decades of clinical practice, offering invaluable insights for both patients and practitioners. To download the review in full, click the following link:

AONM: Through The Looking Glass Review

The AONM review praises the “impressive updated explanation” of how the Perrin Technique works, building on Ray’s groundbreaking 2020 Medical Hypotheses article, which linked disturbances in the neuro-lymphatic drainage to Long COVID and ME/CFS. The review also highlights how the book explores the role of the subarachnoid lymphatic-like membrane (SLYM), describing the publication as both timely and comprehensive.

Interest in Dr. Perrin’s work has surged following coverage in The Telegraph and other media. Since its release on 7th November, Through the Looking Glass sold out within one week due to overwhelming demand, with limited stock now remaining of Dr. Perrin’s other books too (The Perrin Technique: Second Edition and Concise Perrin Technique Handbook)

Perrin Technique™ featured in The Telegraph

by Newspost

An article published online in The Telegraph spotlights Dr. Raymond Perrin’s work and the development of the Perrin Technique for ME/CFS and long COVID.

It explores the origins of the technique, discusses the recent major breakthroughs in science which back up the foundations of the Perrin Technique and includes insights from the latest book, Through the Looking Glass.

Prof. Adrian Heald, consultant physician at Salford Royal (part of Northern Care Alliance NHS Foundation Trust), adds valuable support from a recognised NHS perspective as he calls for more research into the Perrin Technique and notes the technique’s “positive results” for ME/CFS and long COVID patients:

“We’re increasingly learning about the physiology on which the Perrin Technique is based. The science is slowly catching up with what Dr. Perrin has been proposing as a technique for many years… Anecdotally we have seen positive results in patients with very difficult to treat chronic fatigue/ME who have been seeing Dr Perrin.”

– Professor Adrian Heald, consultant physician at Salford Royal (part of Northern Care Alliance NHS Foundation Trust)

The full article is available here via The Telegraph’s website (subscription required, with a free month’s trial available)

Following its global online publication in November which sparked significant interest, Dr. Perrin’s interview with The Telegraph was also featured in print on 11th January in the UK. This fantastic feature continues to shine a spotlight on the Perrin Technique, helping to spread awareness worldwide.

STUDY CONFIRMS BRAINS WASTE-CLEARANCE PATHWAYS IN HUMANS

by News

A groundbreaking study from Oregon Health & Science University (OHSU) has, for the first time, confirmed the existence of a functioning glymphatic system in living humans — a theory central to the Perrin Technique!

ARTICLE: Study Confirms Brains Waste-Clearance Pathways in Humans

Researchers recruited five volunteers undergoing neurosurgery between 2020-2023. During the procedure, the volunteers received an injection of a dye (gadolinium) into their cerebrospinal fluid, followed by MRI scans to trace the dye’s movement through the brain. The results, published on October 7, 2024, in the Proceedings of the National Academy of Sciences (PNAS), show cerebrospinal fluid flowing through perivascular spaces, detailing a waste-clearance network in the brain

This mapping of pathways that clear neurotoxins to the body’s lymphatic and venous systems offers powerful validation for Dr. Perrin’s approach to treating ME/CFS, Fibromyalgia, long COVID, and other conditions.
