Could Alzheimer's be transmitted by viruses and bacteria?

The Alzheimer It is one of the most worrisome diseases of recent times, due to the large number of people affected by it and the impossibility of knowing its origin accurately.

For this reason, some scientists believe that it is best to completely change the direction of their research and begin to think that, perhaps, the origin of the disease has nothing to do with what has been assumed so far.

This is what those responsible for an article say editorial, published in Journal of Alzheimers Disease, which deals with the possible implication of bacteria and viruses how the disease is going.

What do we know about Alzheimer's so far?

As you know, Alzheimer's is a neurodegenerative disease that manifests itself through a cognitive decline, which leads to abnormal behaviors on the part of the patient and, finally, in death.

As a common factor, accumulation in the brain ofamyloid plaques and tau proteins badly folded. This leads to failures in the communication system of the neurons and, therefore, it ends up generating this cognitive disorder. Okay, so this is the most commonly accepted theory, but how does it happen?

Why might Alzheimer's be transmitted by viruses and bacteria?

According to these scientists, it could be that those responsible for these biochemical changes are microorganisms, how bacteria or viruses. Specifically, they focus their attention on the herpes simplex 1 (HSV1), the Chlamydia and some spirochetes.

The origin of their theories is based on the evidence of some possible cases of Alzheimer's transmission through surgeries and blood transfusions and, furthermore, in the existence of many scientific studies around this topic, especially in the case of the Herpes Virus.

Although they cannot demonstrate that this is true, they consider it correct due to evidence such as typical inflammation of the disease, which could be associated with microbial infections, or the known effects of HSV1 on the nervous system.

What do other scientists think?


In research, one cannot contradict a theory if there is no evidence to invalidate it, especially in the case of Alzheimer's, where so much remains to be discovered. For this reason, many researchers are cautious when sharply denying these theories, which do not stop being part of a very minor point of view.

However, as one of the investigators responsible for the editorial affirms, we must have the open minded and do not leave aside any of the possible directions of the investigation. Thus, if these theories were finally proved, being able to treat the disease would be as simple as choosing the antimicrobial drug appropriate.

Science is like that. No theory should be discarded and all hypotheses that have a minimum of credibility must be tested. Only then, someday it will be possible to delve into the origins of diseases like this.
