Evaluation of Association Between Testosterone Levels, Dementia, and Adverse Mental Health Outcomes

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Yes
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT04743466
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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.
