       | Oh yeah for sure. Other herpes link: It can be even worse if you
       | somehow get it in your nose, where it could be a causal factor in
       | "learning and behavioral deficiencies and violence in children
       | and adults", as well as other risks from other forms of herpes
       | like HHV-6 via that route, nice and close to the brain, and also
       | possibly linked to the development of multiple sclerosis. [1][2]
       | It's worth noting to those that don't know that this virus lies
       | dormant in your spinal cord and can eventually travel to the
       | brain, causing encephalitis and as the research has actually been
       | saying for some time now is probably also linked to alzheimers,
       | and there's also an increased incidence of alzheimers between
       | spouses [3]. Lots of indications that we should probably figure
       | out a way to stamp these viruses out if we're to totally be past
       | these extremely debilitating and life ending conditions as a
       | species.

         | 
         | There are plenty of diseases where we have identified multiple
         | risk factors successfully. We have examples of diseases where
         | either risk factor alone is often causative (e.g. pulmonary
         | cancer can be caused by smoking, or by long term asbestos
         | exposure, and if exposed to both, fixing just one won't make
         | the risk very low; and there are of course many other
         | substances that can cause this). And we have also identified
         | diseases where you need two (or sometimes more) separate
         | factors to trigger it (e.g. shingles is a diseases that is
         | triggered in individuals that previously had chickenpox, but
         | generally only if their immune system is weakened by something
         | else, typically old age).

       | 
       | That's the rub. Even if this non-traditional brain model is to be
       | taken at face value, there is a missing variable somewhere,
       | arguably more important; HSV-1, at best, would be a contributing

         | That is mixing up necessary versus sufficient. If _all_ people

         | Alzheimer's and _all_ people who did not contract HSV-1 do not
         | develop Alzheimer's (technically implied by my first
         | statement), then you can make a good case for causality.
         | Obviously you can do better, but that is a good start.
