Ruth Itzhaki challenges Alzheimer's research with viral link that sparks controversy
- Ruth Itzhaki spent decades researching the connection between Alzheimer’s disease and the varicella-zoster virus.
- Her work faced significant skepticism from the scientific community, and she often worked in isolation.
- Recent studies have started to validate her theory, indicating shingles vaccinations may lower dementia risk.
In the United Kingdom, Ruth Itzhaki, an emeritus professor at Manchester University, has spent decades pursuing a controversial hypothesis that links Alzheimer’s disease to the varicella-zoster virus, which causes shingles. Initially met with skepticism and derision from the scientific community, Itzhaki faced significant difficulties while advocating her theory. Her research was often conducted in solitude, and she described her struggles likening them to 'repeated burning as a heretic at the stake.' Despite the challenges, recent studies have begun to validate her long-held beliefs, showing that the shingles vaccine may help reduce the risk of developing dementia. On April 5, 2025, Itzhaki noted that she is no longer treated with contempt and is now being recognized for her contributions to this important field. At an age when many of her peers are retired, she is still actively engaged in reviewing research from around the world, marking a significant turnaround in her career and the perception of her work within the scientific community. This vindication highlights a shift in understanding the potential viral contributions to Alzheimer’s, emphasizing the need for further investigation into vaccine benefits in dementia prevention, a topic gaining traction in ongoing medical conversations.
