Reacción a "Reactions: pre-publication claims part of dementia cases are caused by herpes-like viruses"

This is an unrevised pre-publication. I hope that the revision process will correct aspects such as that: 

1. Dementias have different aetiologies: talking about a virus causing any one of them already indicates that it is not causal. 
2. Seven years is a ridiculous period to date the cause of Alzheimer's disease, for example, which starts about 20 years earlier. 
3. They compare the seven-year risk of subjects around 80 years of age at the time of vaccination, of whom not all eligible subjects are vaccinated, but only 40 %. At those ages, 40% is probably a biased number. They say they do not compare those who were vaccinated and those who were not: they should, to assess whether there is a bias.  

Honestly, I don't think this pre-publication deserves much attention. We will see if it is published and how the content appears in its final version. From what I have read, I don't believe it.
