NCT04743466 · ACTIVE NOT RECRUITING
Evaluation of Association Between Testosterone Levels, Dementia, and Adverse Mental Health Outcomes
This study looks at existing health records and biobank data to see whether low testosterone levels are linked to higher rates of dementia, depression, and anxiety. It is not a drug trial — no one is given a treatment. Researchers are mining data already collected from large databases like the UK Biobank. The phase is unspecified because this is an observational records study, not a clinical intervention trial.
You may qualify if
- Have volunteered to participate in institutional or national biobanks, mainly the UK Biobank and the Kaiser Permanente Research Bank, and those that have previously participated in studies that resulted in de-identified clinical and genetic data being make available on public archives, mainly the database of Genotypes and Phenotypes (dbGaP)
- No special populations (adults unable to consent, individuals not yet adults, pregnant women, or prisoners)
