Testosterone is a sex hormone that’s important for reproduction and development. As men get older, they experience a significant decline in their levels of testosterone.
Some studies have shown that males with dementia have lower levels of testosterone, which has led to claims that lower levels of testosterone might be associated with the development of dementia. However, other studies have shown that there is no difference in testosterone levels between men with and without dementia.
There has yet to be clear evidence that supports a causal link between testosterone level and relative risk of dementia.
As a result, it is unlikely that taking testosterone will help reduce your dementia risk.
Further, there are risks with taking hormones that need to be considered in the context of your individual health.
