We don't need a clinical study for that. This is simple, indisputable physiology."
This well-known German neurologist and neurophysiologist, Dr. Margarite Griesz-Brisson,  warns of a tsunami of dementia years down the road because of oxygen deprivation from wearing masks today. Are you willing to risk your brain to scientifically unfounded, politically-motivated mandates. ? TN Editor

Dr. Margarite Griesz-Brisson MD, PhD is a Consultant Neurologist and Neurophysiologist with a PhD in Pharmacology, with special interest in neurotoxicology, environmental medicine, neuroregeneration and neuroplasticity. This is what she has to say about facemasks and their effects on our brains:

"The reinhalation of our exhaled air will without a doubt create oxygen deficiency and a 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 reaction time – reactions of the cognitive system.
