Does this improve the likelihood that it is treatable?<p>Some previous theories had been that Alzheimer&#x27;s was essentially genetic. But never fully genetic, instead of guaranteeing your chance of getting it, it just increases the likelihood.<p>So my question is: Could this hint at Alzheimer&#x27;s being the result of some yet undetected infection in the brain that some people are more prone to due to genetics, and that is transmitted due to brain tissue sharing?<p>PS - What I am asking about isn&#x27;t that far from the latest research, see: <a href="http:&#x2F;&#x2F;www.medscape.com&#x2F;viewarticle&#x2F;574944_4" rel="nofollow">http:&#x2F;&#x2F;www.medscape.com&#x2F;viewarticle&#x2F;574944_4</a>
