Dr. Margarite Griesz-Brisson M.D., Ph.D., is a Consultant Neurologist and Neurophysiologist. She has a Ph.D. in Pharmacology, with special interest in neurotoxicology, environmental medicine, neuroregeneration and neuroplasticity. Dr. Grisz-Brisson is the founder and medical director of the London Neurology and Pain Clinic.
She holds membership in the American Academy of Neurology, the European Federation of Neurological Societies (EFNS), the General Medical Council, United Kingdom, the German Medical Association, the Swiss Medical Society, the European Academy for Environmental Medicine, the International Board for Clinical Metal Toxicology.
She holds medical licenses in Germany, USA, Switzerland, United Kingdom, Qatar, and Norway. She is one of the foremost experts in the world on the effects of oxygen deprivation on the brain.
Dr. Griesz-Brisson states that wearing a mask over one’s mouth and nose creates an oxygen deficiency and an increased intake of carbon dioxide. It causes an oxygen deficiency for the brain cells. In essence, the brain is being suffocated, which causes irreversible degeneration of the brain. She states that this is particularly a problem with children whose brains are developing. Depriving the developing brain of needed oxygen causes brain damage that “cannot be reversed.”
Dr. Griesz-Brisson’s opinion is backed up by scientific studies. Dr. Baruch Vainshelboim, Ph.D., who is a clinical exercise physiologist, specializing in pulmonary rehabilitation. He is presently working at the Cardiology Division, Veterans Affairs Palo Alto Health Care System/Stanford University, Palo Alto, CA. Vainshelboin published a meta-analysis of studies measuring the safety and effectiveness of masks worn to prevent the spread of COVID-19. [Notice: in July 2021 the published study was retracted by the publisher] Dr. Vainshelboim explained that at sea level the oxygen level is 20.9%. Dr. Vainshelboim cites the OSHA standards for safe oxygen levels. He states that “[r]espiratory Protection Standards from Occupational Safety and Health Administration, US Department of Labor states that breathing air with O2 concentration below 19.5% is considered oxygen-deficiency, causing physiological and health adverse effects. These include increased breathing frequency, accelerated heart rate and cognitive impairments related to thinking and coordination.”
While that information from Dr. Vainshelboim is informative, Dr. Vainshelboim failed to explain the relationship between the OSHA safe oxygen level and mask-wearing. As I explained in a previous blog article, “when a mask is put over the wearer’s mouth and nose, the oxygen level that is being breathed back in by the wearer of a mask drops to a range between 17% and 18%. That reduced level of oxygen, according to OSHA, is “immediately dangerous to life.” And it does not matter whether it is a surgical mask, an N95 mask, or a thin cloth covering. In tests, using all different types of masks, the oxygen level for the wearer dropped to a level below 19.5%, which OSHA has determined is an “oxygen-deficient atmosphere” that is “immediately dangerous to life.”
Dr. Vainshelboim concluded that face masks are ineffective in preventing the spread of COVID-19 and, more pertinently, “[l]ong-term practice of wearing facemasks has strong potential for devastating health consequences. Prolonged hypoxic-hypercapnic state compromises normal physiological and psychological balance, deteriorating health and promotes the developing and progression of existing chronic diseases.”
Let us get back to Dr. Griesz-Brisson. She unequivocally warned that prolonged mask-wearing for hours on end will cause irreversible brain damage. She characterizes it as “criminal” to require that children wear masks because of the devastating effects of depriving the children of needed oxygen to their brain as it is developing. As with adults, the effects of oxygen deprivation are irreversible.
The rebreathing of our exhaled air will without a doubt create oxygen deficiency and flooding of carbon dioxide. We know that the human brain is very sensitive to oxygen deprivation. There are nerve cells for example in the hippocampus, that can’t be longer than 3 minutes without oxygen – they cannot survive. The acute warning symptoms are headaches, drowsiness, dizziness, issues in concentration, slowing down of the reaction time – reactions of the cognitive system.
However, when you have chronic oxygen deprivation, all of those symptoms disappear, because you get used to it. But your efficiency will remain impaired and the undersupply of oxygen in your brain continues to progress.
We know that neurodegenerative diseases take years to decades to develop. If today you forget your phone number, the breakdown in your brain would have already started 20 or 30 years ago.
While you’re thinking, that you have gotten used to wearing your mask and rebreathing your own exhaled air, the degenerative processes in your brain are getting amplified as your oxygen deprivation continues.
That Mask is Giving You Lung Cancer? The second problem is that the nerve cells in your brain are unable to divide themselves normally. So in case our governments will generously allow us to get rid of the masks and go back to breathing oxygen freely again in a few months, the lost nerve cells will no longer be regenerated. What is gone is gone.
[..]I do not wear a mask, I need my brain to think. I want to have a clear head when I deal with my patients, and not be in a carbon dioxide induced anaesthesia.
[..]There is no unfounded medical exemption from face masks because oxygen deprivation is dangerous for every single brain. It must be the free decision of every human being whether they want to wear a mask that is absolutely ineffective to protect themselves from a virus.
For children and adolescents, masks are an absolute no-no. Children and adolescents have an extremely active and adaptive immune system and they need constant interaction with the microbiome of the Earth. Their brain is also incredibly active, as it has so much to learn. The child’s brain or the youth’s brain is thirsting for oxygen. The more metabolically active the organ is, the more oxygen it requires. In children and adolescents, every organ is metabolically active.
To deprive a child’s or an adolescent’s brain of oxygen, or to restrict it in any way, is not only dangerous to their health, it is absolutely criminal. Oxygen deficiency inhibits the development of the brain, and the damage that has taken place, as a result, CANNOT be reversed.
The child needs the brain to learn, and the brain needs oxygen to function. We don’t need a clinical study for that. This is simple, indisputable physiology. Conscious and purposely induced oxygen deficiency is an absolutely deliberate health hazard and an absolute medical contraindication.
An absolute medical contraindication in medicine means that this drug, this therapy, this method or measure should not be used – is not allowed to be used. To coerce an entire population to use an absolute medical contraindication by force, there must be definite and serious reasons for this, and the reasons must be presented to competent interdisciplinary and independent bodies to be verified and authorized.
When in ten years, dementia is going to increase exponentially, and the younger generations couldn’t reach their God-given potential, it won’t help to say “we didn’t need the masks”.
They are trying to suppress the important information from Dr. Griesz-Brisson. The website that once contained her interview and the partial transcript of it was shut down. In addition, YouTube deleted Dr. Griesz-Brisson’s video presentation.
I was able to track down the deleted website using the internet WayBack Machine. I was also able to fnd a reposting of the original article. I was also able to find an audio of an English translation of Dr. Griesz-Brisson’s video presentation posted on BitChute. It is posted below.
But what Reuters did not tell its readers is that the study involved 30 people who walked while wearing a mask for only six (6) minutes. You read that correctly, the study was of persons who wore surgical masks for only six (6) minutes. The blood of the study patients was then measured using pulse oximetry. Of course, there will be no change in the blood oxygen level of test patients who only wore their masks for six (6) minutes. That is what you call a rigged study. Children wear masks from the time they get on the school bus until they get home 6 to 8 hours later. Why did they not do a six (6) hour mask study? The answer is obvious. They know that such a study would show that masks are dangerous.
Since there is no asymptomatic transmission of COVID-19, there is no need to require masks. There is no benefit to the masks. They only harm children. Consider the German study that showed detrimental effects on the physical and mental health of children.
A German study involving over 25,000 children reveals that major negative impacts on the physical, psychological, and behavioral health of children may be far more widespread than reported in the media and by government officials — affecting approximately 68% and contributing to 24 distinct health complaints, according to parent submitted observations.
The study states:
In this publication, we report the results from the parents, who entered data on a total of 25,930 children. The average wearing time of the mask was 270 minutes per day. Impairments caused by wearing the mask were reported by 68% of the parents. These included irritability (60%), headache (53%), difficulty concentrating (50%), less happiness (49%), reluctance to go to school/kindergarten (44%), malaise (42%) impaired learning (38%) and drowsiness or fatigue (37%).
