Story summary

A Taiwanese study indicates that higher testosterone levels may impair cognitive performance while enhancing behavioral symptoms in older adults with dementia.
The research involved 94 Alzheimer’s patients, using the ADAS-Cog for cognitive assessment and the Neuropsychiatric Inventory for behavioral symptoms.
Findings revealed a correlation between higher testosterone and poorer cognitive scores, but improved mood and nighttime behaviors.
Testosterone's impact may depend on individual biological conditions and oxidative stress levels.
The study's limitations include its cross-sectional design and small sample size, highlighting the need for further research.
