According to the World Health Organization, there are approximately 10 million new cases of Alzheimer’s disease and other forms of dementia around the world each year. That corresponds with about 1 new case every 3 seconds. As demographic shifts enable people to live longer, the total number of people living with this disease is expected to double over the next 20 years.
Inflammation in the brain can occur any time you have been exposed to a virus. Even without directly infecting brain cells, viruses are capable of triggering such a strong inflammatory response that it overwhelms the whole body. The Covid-19 virus, for example, is particularly adept at triggering a robust immune response. In some cases, inflammation-induced damage to the brain can persist even after symptoms are cleared.
Increasing reports now suggest that exposure to chickenpox and subsequent shingles reactivation may be linked to Alzheimer’s disease. In brain tissue samples, researchers have observed that exposure to the varicella-zoster virus triggers the formation of beta-amyloid aggregates and abnormality phosphorylated tau, resembling the amyloid plaques and neurofibrillary tangles that are characteristic of Alzheimer’s disease.
In this study, Cumin et al. began by obtaining human stem cells that resemble brain tissue. These cells were then exposed to the varicella-zoster virus. Although they did not observe the formation of beta-amyloid and tau proteins, researchers measured increased levels of proinflammatory cytokines, confirming their hypothesis that the correlation between chickenpox and Alzheimer’s disease may be indirectly driven by inflammation.
