Due to growing use of medicinal and recreational cannabis among elderly populations, it is important to understand the effect of cannabis use on their brain. It is known that cannabis use may impair cognition when used extensively in adolescence. Yet, how it affects the brain when used in older ages is unknown. Therefore, we will explore the association between history and pattern of cannabis use and cognitive function as well as brain structure as demonstrated by brain imaging. Analyses will be cross-sectional looking at cognitive function and brain MRI measures at one point as well as longitudinal looking at change in outcomes over time. Exploring the associations between cannabis use and brain health in older adults offer an opportunity to observe potential harm or benefit of cannabis use in a population at increased risk for cognitive decline and dementia . The duration of this project is estimated to be 3 years.
