I think that Alzheimer's likely has many causes. This research indicates that the chickenpox/shingles virus may be related to about 20% of dementia cases - so not all Alzheimer's but an appreciable amount. It could be that other cases are caused by other Herpes viruses, or maybe Epstein Barr - vaccines for those may reduce it even more
