Research using 108 subjects involving the treatment of early Alzhiemers recently had an 80% improvement rate including a 20% reversal of of physical neruonal plaque and behaviors associated with the disease.
The inspiration for the unique treatment stemmed from noticing that the brain itself seemed to mimic diabetes like symptoms among Alzhiemers patients.
The treatment is simply the dispersal of aerosolized insulin in gas form sprayed directly into the brain with a specialized needle through the nose and into the base of the brain.
Earlier research had similar but less dramatic results by using Niacin in astronomical amounts which also requires bypassing the blood brain barrier by specialized injection.
