At REbrain Clinic, we believe there is a way out of the dark

REbrain Clinic teaches you about the important functions of the brain, always related to actions that you have been recommended to take

REbrain Clinic helps with relevant treatment and optimization of the brain 

REbrain Clinic was founded in 2020 by Marianne Sandberg from a desire to help people towards better brain function, especially after concussion, neck injuries and mental trauma. People who feel they have not got enough help in the established health care system which might have given up on them, but who themselves do not want to give up. 

REbrain Clinic is built on two foundation stones and offers: 

  1. Interdisciplinary rehabilitation advice and help to find some of the most skilled specialists, doctors and therapists internationally.
  1. Natural methods for optimizing the brain using an individual intensive approach the REbrain method.

The advice is based on science, the methods are practiced internationally and are selected on the basis of Marianne Sandberg’s: 

  • 10 years of research in neuroscience, interdisciplinary medicine and new methods in brain rehabilitation – as well as 3 years of basic research in microorganisms of importance to the brain-intestinal connection. 
  • Knowledge of where to go for better diagnoses and the latest science-based treatment. 
  • Experience from her own international course of rehabilitation. 
  • Certified in the United States in advising on brain health.

The REbrain method is aimed at finding root causes and imbalances and then repairing them, typically with proven methods from recent areas of research. 

REbrain Clinic works together with some of the best, most progressive specialists in the diagnosis and treatment of invisible brain injury in the EU and worldwide. The doctors we work with are at the forefront of research and development in scanning, diagnostic tools, therapies and training. Other partners are university-educated scientists who have chosen cell biology, immunology, intestinal and neuroscience as their approach to natural treatment and dietary guidance. 

Research collaboration  

REbrain Clinic aims to be part of practical, clinical research partnerships and therefore welcomes any doctor, psychologist, neurobiologist or intestinal researcher (microbiome and brain) to do research together with us, preferably through the scientific non-profit organization 

It is only through scientific collaboration and outcome measurements that we can gradually demonstrate evidence of the efficacy of our ground breaking methods. 

We hope, one day, that our methods will be available to everyone and not, as now, only for those with deep pockets 

About the founder 

Marianne Sandberg has an MSc from the prestigious Technical University of Denmark (DTU). Major in biotechnology, biochemistry, food, cell biology, biological processes, immunology, and human physiology.  Specialization and peer reviewed research in anaerobic cell metabolism (intestinal/gut bacteria).  

In 2007, Marianne Sandberg had to give up work because of a sports concussion. After not getting any help from MDs, she spent the next 10 years traveling the world finding new methods of rehabilitation and familiarizing herself with the available scientific literature on neck-brain injuries and related late comorbidities. 

Marianne Sandberg managed to recover and was able to work again in 2017, using a combination of many different therapy methods she found at home and abroad. She now wants to use her accumulated knowledge and experience to help others in the same boat. You can read more about Marianne’s personal history and professional background here.
