It is known that neurodegenerative diseases are one of the main causes of mental and physical disabilities. Millions of individuals across the age spectrum suffer from neurological disorders, ranging from children with ADD, ADHD, ASD and other developmental disorders, people with epilepsy to seniors with ALS. We have autoimmune conditions, MS, Parkinson's, Stroke, and various forms of dementia. This informative study appears to suggest that some of these disorders may be due to breaching of the blood brain barrier (BBB). High frequency Radiofrequencies have been demonstrated in scientific studies to open the blood brain barrier allowing toxic substances to enter. Dr Allan Frey was one of the pioneer scientists to discover that weak radio frequency signals—just like those from today’s cell phones—opened up this normally closed barrier. Frey first injected dye into the bloodstream of rats and then exposed them to very weak pulsed microwave signals. Within a few minutes, the injected rats’ brains began to fluoresce, signalling that the blood-brain barrier had been breached.  There have been numerous studies since that confirm and/or extending Frey’s work i.e. Salford 1994, Nittby 2009, Vojdani 2014
Given the increased diagnosis of autism, dementia and other neurological impairments I think it is imperative that the medical community direct further studies towards determining and confirming the roles chronic microwave exposure (WiFi, Mobile Phones, Base Stations etc.) has on neurodegeneration.
