“Having just one copy of this gene variant does not impact someone’s health or increase their risk of dementia. However, having two copies of the variant more than doubled the risk of dementia in men, but not women,” Professor Olynyk said.
“While the genetic variant itself cannot be changed, the brain pathways which it affects – leading to the damage that causes dementia – could potentially be treated if we understood more about it.”
Professor Olynyk said further research was needed to investigate why this genetic variant increased the risk of dementia for males but not females.
