研究发现,吸食重大麻与痴呆症风险大幅增加相关联。 Heavy cannabis use linked to a significant increase in dementia risk, study finds.

JAMA神经学的一项新研究表明,大量使用大麻会大大增加痴呆症的风险。 A new study in JAMA Neurology shows that heavy cannabis use can sharply increase the risk of dementia. 这项研究分析了来自超过600万45岁及45岁以上的安大略人的数据,发现由于使用大麻而需要住院治疗的个人在五年内患痴呆的风险比一般人口高72%。 The research, which analyzed data from over six million Ontarians aged 45 and older, found that individuals requiring hospital care due to cannabis use had a 72% higher risk of dementia within five years, compared to the general population. 甚至那些因使用大麻而前往急诊部门的人的风险也增加了23%。 Even those visiting emergency departments due to cannabis use had a 23% increased risk. 虽然研究表明,大量使用大麻可能会影响大脑结构和增加痴呆症风险,但还需要进一步研究,以建立直接因果关系。 While the study suggests that heavy cannabis use might affect brain structure and raise dementia risk, further research is needed to establish a direct cause-and-effect relationship.
