Will preventing and/or removing bacterial transfer to the brain be an effective treatment for Alzheimer’s disease, and if not, is it actually caused by a virus?

This is an insight you had in thinking about the intriguing possibility that such a complex and devastating neurological condition might have a simple but subtle initiating cause, as was proposed in the case of gum disease preceding an eventual migration of organisms to the brain. While that can happen, it is not the cause of Alzheimer's per se. That, indeed, is viral and that is the wisdom you are bringing forth, coupled with your intuitive reach, to go beyond the barriers of current thinking, which act as a kind of prison, in the way of creative insight. As with many infections, it is the combination of karmic vulnerability and exposure to a causative agent that gets the ball rolling and leads to a progressive loss of function from a serious impairment. Without the karmic backdrop, it is likely the virus would never take hold, or if it did, would cause only mild symptoms of a transient nature and not a relentless lifelong downward spiral. In the case of people who are under stress and deeply troubled, that is a third factor predisposing them to have a nasty time if exposed to the virus, because it will both impair immune defenses as well as stir up old karmic vulnerabilities. When the deep subconscious goes looking for answers and sees the many past life traumas that have been endured and often caused devastating and life-shortening problems, thus armed with ever more to worry about, the deep subconscious can undermine the self from within and that will lower resistance to infection as well, creating a perfect storm of negativity from which a person might not recover. Given that past life trauma is so enormous on average, and that life presents many challenges that will cause a karmic rumbling of past challenges and obstacles to personal progress and happiness, being able to clear virus particles from the body using the Lightworker Healing Protocol and Deep Subconscious Mind Reset provide the most powerful way to nip things in the bud and prevent dementia from getting started. So this brings things full circle, as you have been probing the causes of Alzheimer's and related disorders for years now and have flushed out the major aspects but for one, and that is what you are doing now, in getting the ultimate source creating the threat of serious illness identified. And now that you have the protocols empowered to the extent needed to inactivate chronic virus infections and clear them, you have the wherewithal to change the landscape in dealing with this dreadful scourge. Like so many disorders that start with chronic low-level viral infection, it can escape detection for many, many, years especially when the medical establishment is manipulated with mind control to look in another direction entirely, through a series of red herrings that are pursued avidly but are only symptoms and not the cause, like plaques and tangles observed in the brain tissue. They are not a cause but a consequence of the ongoing battle resulting from the presence of the virus, and being able to clear that will be a game changer.
