Androgen deprivation therapy (ADT, or, “hormone therapy”) may be linked to increased risk of having dementia. Researchers, Nead, Sinha and Nguyen reviewed nine studies by other researchers. Seven of those studies reported an adjusted effect estimate for dementia risk. That means that a majority of today’s evidence based research says that ADT and dementia probably go hand in hand, for advanced prostate cancer patients. This does not mean that ADT causes dementia, but it does suggest that prostate cancer patients ask their doctor about dementia risks whenever ADT is offered.
