New research provides evidence the body has a fast-track brain cleansing system that prevents diseases such as Alzheimer’s and maintains brain health. Finding ways to support and enhance this cleansing process could lead to improved outcomes in brain injury and brain disease. Read on to find what scientists have discovered and how craniosacral therapy effectively promotes brain health by invigorating this active fluid cleansing system. Most of us have heard of the lymphatic system, the collection of vessels and nodes running throughout the body that helps cleanse waste products and is part of the body’s immune system. Now a team of neuroscientists at the University of of Rochester Medical Center has identified a fascinating fast-track cleansing system in the brain called the glymphatic system.
Their findings, published online in the August 2012 issue of Science Translational Medicine, were only possible using the new technology of two-photon microscopy. This allows researchers to study and track the flow of blood, cerebrospinal fluid (CSF) and other substances in live brain tissue. The glymphatic pathways only operate in a living brain, so they were not scientifically observable until now. Scientists named it the glymphatic system because it functions much like the lymphatic system but is managed by the glial cells within the brain. Glial cells are non-neuronal brain cells with several regulatory and protective roles including destruction of pathogens and removal of dead nerve cells.
What the two-photon microscope shows is glymphatic pathways circulating CSF efficiently throughout every part of the brain, along specialised anatomical structures. Previously scientists hypothesised that CSF slowly trickled through brain tissue and filtered out waste material gradually, but this is only part of the picture. Now we know the glymphatic system is pushing large volumes of CSF very quickly and very deeply into the brain, much faster than was previously thought, to transport waste away under pressure. Specifically, a bulk flow process moves CSF via the arterial system right into the brain tissue, exchanging with the interstitial fluid inside the brain. As it does, it washes through the tissue collecting waste particles that are sitting in between the brain cells. The CSF then enters the venous system via veins within the brain tissue, taking the fluid and the waste it picks up away from the brain. In this way waste material is efficiently removed from the brain tissue, by the CSF, via the circulatory system. We know accumulation of waste and toxic matter in the brain environment adversely affects brain function. The discovery of the glymphatic system opens up the research field. Neuroscientist Maiken Nedergaard said, “We’re hopeful that these findings have implications for many conditions that involve the brain, such as traumatic brain injury, Alzheimer’s disease, stroke, and Parkinson’s disease”. The focus is finding how the glymphatic system might be implicated in cause and/or recovery. Here’s one example.
The Glymphatic System and Alzheimer’s Disease
One of the first extracellular waste products researched in the context of glymphatic cleansing was amyloid β. Amyloid β is a protein made and secreted by the brain cells in an on-going process and used to perform several regulatory and protective functions. Because the brain is continuously producing this molecule it needs to clear out any amyloid β it’s no longer using.
In Alzheimer’s disease the amyloid β builds up in the brain, clogging up the spaces in between the cells. Researchers think it’s these amyloid β plaques that kill the neurons and cause the dementia that is a primary symptom of Alzheimer’s. In Alzheimer’s the glymphatic cleansing pathway may be failing, causing the increasing deposition of amyloid β. The fast-track cleansing pathway may have stopped working properly due to deterioration through ageing processes, or the effect of a previous infection or injury. It may be possible to slow the progression of Alzheimer’s by increasing the rate of flow of the glymphatic system, thereby flushing the amyloid β out more quickly. Where deposits of amyloid β have accumulated, improving the glymphatic flow and its cleansing effect could break down and reduce these deposits and clear them more quickly from the brain via the circulatory system. The good news is we already have an effective therapy for improving glymphatic flow. CranioSacral Therapy Enhances Glymphatic Cleansing Although glymphatic cleansing is a newly identified process, the concept of a stronger fluid motion through the brain is not new. Craniosacral therapy pioneer Dr. John Upledger hypothesised his “Pressurestat Model” of fluctuating CSF production within a semi-closed hydraulic system back in the early 1980s. This model of CSF moving under pressure within the dural membranes surrounding the brain and spinal cord was the basis of his evolving research and development of craniosacral therapy. There is now an extensive body of evidence of the health-promoting effects of craniosacral therapy, published by craniosacral therapists among a worldwide network of practicing clinicians. Craniosacral therapy is a gentle, hands-on body therapy that engages with the body’s craniosacral system, the interactive physiological environment surrounding and protecting the brain and spinal cord. The focus in craniosacral therapy is encouraging the release of trauma locked within the tissues, improving physiological function and promoting the body’s natural healing processes. Craniosacral techniques restore and enhance fluid movement within the brain and spinal cord and throughout the whole body. During craniosacral therapy cerebrospinal fluid motion is increased, improving glymphatic flushing of the brain tissues. Adequate flushing of the brain environment is essential for brain detoxification, nutrition and normal range of function. Scientists’ recent discovery of the glymphatic system’s mechanism informs Dr. Upledger’s earlier hypothesis. Just as importantly, it affirms craniosacral therapy as an effective and established treatment option for enhancing brain cleansing in cases of brain disease or injury and as a preventative measure.

Babies who have had a difficult/fast/slow birth or a Caesarean can suffer with a variety of difficulties that make it hard for them to settle into a good routine and CranioSacral Therapy is a wonderfully gentle and non-invasive way of helping babies with such problems.
All of these problems can be the babies way of telling you they are uncomfortable, having restrictions in their cranium or bodies all of which can be gently and effectively helped with CranioSacral therapy. If you are unsure if this amazing therapy would help your baby please do contact the Therapy life centre to talk through your concerns.
Young children respond very well to the gentle re-balancing of the CranioSacral system. All ages can be helped by this therapy and some of the conditions treated are:
Teenagers can gain great benefit from the gentle release of the CranioSacral system.
“We have found that our son, who suffers from both a sensory integration disorder and a digestive disorder, has benefited from a multi-faceted approach combining diet, behaviour therapy ,occupational therapy and physical therapy, including Cranial therapy. These helped to reduce stress and anxiety in our son, which in turn helps to mitigate the effects of the disorders from which he suffers. Whilst no one method can completely erase or overturn spectrum disorders in our opinion, a multi-faceted approach including Cranial therapy, can help a child to make genuine progress in recovering from such disorders.”
For a very young baby the treatment can be carried out either lying on the therapy couch or while being held by the Therapist or parent. Sometimes the babies do cry during the treatment which is a natural response.
Young toddlers/children are often treated while they are playing sitting on the floor or on a parents lap.
Once the child is happy to lie on the treatment couch, treatment will mainly be in lying.
Older children usually still have a half hour session however depending on their needs this may have to be a one hour session.
A typical session will last approximately one hour. The patient will remain fully clothed (it is a good idea to wear comfortable clothing) and lie down on a padded couch. The therapist will evaluate by gently touching various parts of the body in order to locate areas of tension and restrictions, which are then released by delicate manual techniques.
The fluids and soft tissues which protect the brain and spinal cord are known as the CranioSacral system. If these do not work properly, it will affect almost every other system in the body. CranioSacral Therapy for children is a safe, gentle, hands on therapy which uses light touch techniques to ease any tensions or restrictions in the body and promote balance in both the central nervous and endocrine systems.
The technique (which has also been referred to as CranialSacral therapy or cranio-sacral therapy) was pioneered and developed by Dr John E Upledger, an American osteopathic physician, who was working as a clinical researcher and Professor of Biomechanics at Michigan State University in the mid 1970s. He founded the Upledger Institute in 1985 to teach the effectiveness of this treatment around the world.
