Clinical Trial Summary

This study evaluates the association between testosterone levels and risk of dementia and adverse mental health outcomes (e.g. depression and anxiety). It is not known whether low testosterone levels may be associated with an increased risk of dementia. Learning about the association between testosterone levels and risk of dementia may help determine the long-term effects of androgen deprivation therapy and may help improve quality of life.


Clinical Trial Description

PRIMARY OBJECTIVE: I. To use a Mendelian randomization study design to determine whether genetically predicted decreased testosterone levels are associated with an increased risk of dementia. SECONDARY OBJECTIVE: I. To examine whether genetically predicted decreased testosterone levels are associated with worse cognitive function and adverse mental health outcomes. OUTLINE: Patients' records from institutional or national biobanks are reviewed. ;
