A Summary of The Latest Medical News: ## Heavy Cannabis Use Linked to Sharp Increase in Dementia Risk, Landmark Study Finds **A new study has revealed a significant link between heavy cannabis use requiring hospital care and the risk of developing dementia among adults aged 45 and older.** **The Scope of the Study** Canadian researchers tracked more than 6 million individuals over the age of 45 who had no prior diagnosis of dementia. The study, conducted between 2008 and 2021, focused on those whose cannabis use led to emergency department visits or hospitalizations[5]. **Dementia Risk Rises Dramatically** Adults over 45 who needed acute hospital care due to cannabis use were found to have a 72% greater risk of developing dementia within five years compared to the general population[2][4][5]. This group was also nearly four times as likely to be diagnosed with dementia as those in the general public without such hospital care for cannabis use[5]. **Comparison With Other Hospital Patients** Even when compared to other individuals hospitalized for any reason, those hospitalized specifically for cannabis use faced a 23% higher risk of dementia diagnosis within five years[2][4]. **Annual Incidence on the Rise** The number of acute care hospitalizations linked to cannabis use in people over 45 has risen substantially. In those aged 45-64, the annual rates increased fivefold during the study period, while among individuals 65 and older the rate jumped 26 times[5]. **Possible Explanations** Heavy, long-term cannabis use has previously been associated with memory problems and changes in brain structure—both of which are linked to dementia[2]. The new findings support these earlier observations and suggest that severe cannabis use severe enough to prompt hospital visits may be a strong risk factor for long-term cognitive decline. **Calls for Caution and Further Research** Dr. Daniel Myran, lead researcher, highlighted the real-world impact: “Long-term and heavy cannabis use has been associated with memory problems in midlife along with changes in brain structure associated with dementia”[2]. Experts unrelated to the study emphasize its large sample size and robust design, underscoring the importance of these findings for public health guidance[5]. **Conclusion** As cannabis use becomes more widespread, especially among older adults, this study serves as a critical reminder of the potential long-term risks. People who experience serious health consequences from cannabis use—especially those requiring hospital care—should speak to their healthcare providers about cognitive health and dementia risk[2][4][5].
