The answer to the question in the title says a great deal about the American medical system and its rampant corruption. From A Midwestern Doctor at midwesterndoctor.com:
Exposing the Great Amyloid Scam and The Cures They Buried for Billions
Story at a Glance:
• Alzheimer’s disease is commonly thought to result from abnormal plaque buildup in the brain that gradually destroys brain tissue.
•Almost all Alzheimer’s research for decades has been directed toward eliminating amyloid, even after the basis for much of this work was shown to stem from fraudulent research.
•The billions spent on amyloid Alzheimer’s research have only produced three drugs, all of which offer minuscule benefits and severe side effects.
•In contrast, affordable and straightforward treatments that reduce dementia or the preceding cognitive impairment have been maligned and buried by the medical industry.
•DMSO for example, has incredible neuroprotective qualities that have spared many stroke and spinal cord injury victims from a life of “incurable” disability. Decades of forgotten research also show it treats cognitive impairment and dementia.
•This article will review the great amyloid scam and the simple therapies for cognitive decline we’re never told about.
Medicine is strongly biased towards adopting biochemical models of disease as this facilitates costly therapeutics being developed for each disease and hence sustains the medical industry. Unfortunately, in many cases, the biochemical approach to disease, at best can manage symptoms, and as a result, many conditions remain “incurable” while non-patentable natural therapies that can cure them languish in obscurity.
