MedPage Today (4/14, George) reports a study suggests that “people that required emergency department (ED) or acute hospital care for cannabis use may have an increased risk of a subsequent dementia diagnosis.” Researchers found that “among adults ages 45 years and older with no history of dementia, those who needed acute care due to cannabis use had a 1.5 times higher risk of a new dementia diagnosis within 5 years compared with patients who had an all-cause acute care encounter.” Notably, the “risk of a new dementia diagnosis for people who needed acute care due to cannabis use was 3.9 times higher than that of the general population.” Researchers stated that “the findings do not show that cannabis use causes dementia.” The study was published in JAMA Neurology.
