Cannabis use and cognitive decline in persons under 65 years of age
Article Abstract:
Cognitive decline appears to be closely associated with aging and educational level, but does not appear to be associated with the use of cannabis (marijuana). A follow-up study to investigate the adverse effects of cannabis use on cognitive decline was conducted on 1,318 residents of East Baltimore, Md. who completed a Mini-Mental State Examination in previous years. After 12 years, scores declined a mean of 1.20 points, but there appeared to be no significant differences in cognitive decline between have, light and nonusers of cannabis.

Methodological issues in the study of cognitive decline
Article Abstract:
Cognition can be measured as it changes or at a single point in time. Conceptual and methodological issues concerning changes in cognitive function include: difficulties in using single measurements and the importance of measuring changes; sources and effects of variations in measurement; the importance of age and education modeling; categorizing outcomes; and using multiple-outcome statistical models.
