What this research studies
If you join, the team will enroll 200 adults aged 50–80 who regularly use cannabis and ask about your cannabis use and reproductive history. You will complete cognitive and mood tests, answer questions about stress, and provide biological samples for hormone and other brain-health markers. The researchers will compare results between men and women to see if hormonal changes or stress relate to memory decline and dementia risk. The goal is to link behavioral and biological measures to better understand who may be at higher risk.
Who could benefit from this research
Good fit: Adults aged 50–80 who regularly use cannabis and are willing to complete cognitive testing and provide blood or saliva samples.
Not a fit: People who do not use cannabis, are younger than 50, or who are seeking an experimental treatment for dementia would not directly benefit from participating in this observational project.
Why it matters
Potential benefit: This work could help show whether older women who use cannabis face higher risk for cognitive decline, leading to clearer guidance and prevention for patients.
How similar studies have performed: Prior studies in younger people and animal models have shown sex and hormone links with cannabis effects, but few studies have examined these questions in older adults, so this builds on existing findings in a new age group.
