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

An international team of scientists, led by Stanford University (United States), has designed a study to analyse the relationship between herpes zoster virus infections and the development of dementia. To do so, they took advantage of the introduction of the Zostavax vaccine against this virus in 2013 in Wales (UK), which people over the age of 80 could not receive. After reviewing data from people around this age over the following seven years, they concluded that the vaccine reduced the relative risk of dementia by 20%. According to the authors, their study, which is in prepublication form and has not been peer-reviewed, "leads to the conclusion that shingles vaccination is most likely an effective way to prevent or delay the onset of dementia".

Reactions: study suggests elite footballers more likely to develop dementia

Swedish research involving more than 6,000 male footballers in the country's top division (between 1924 and 2019) indicates that they were 1.5 times more likely to develop a neurodegenerative disease compared to the population analysed who were not involved in professional football. Unlike outfield players, goalkeepers did not have this increased risk, which, according to the authors, supports the hypothesis that impacts to the head when striking the ball could explain the increased risk. The study is published in The Lancet Public Health.
