There is evidence of short-term negative effects of cannabis use on cognition, but only a limited number of studies have explored the association between cannabis use and age-related cognitive decline. The aim of the present study was to investigate the relationship between cannabis use and age-related cognitive decline from early adulthood to late midlife.<\/p>\n<h3 class=\"wp-block-heading\" id=\"brb370136-sec-0020-title\">Methods<\/h3>\n<p>The study population consisted of 5162 men who had participated in Danish follow-up studies on cognitive aging. These studies included scores on the military intelligence test B\u00f8rge Prien\u2019s Pr\u00f8ve from both the conscription assessment (mean age\u00a0=\u00a020\u00a0years; p1 and p99: 18 and 26\u00a0years) and from the follow-up (mean age\u00a0=\u00a064\u00a0years; p1 and p99: 55 and 72\u00a0years) as well as extensive data on lifestyle and health from the follow-up questionnaires. The association between cannabis use and age-related cognitive decline was investigated in linear regression models.<\/p>\n<h3 class=\"wp-block-heading\" id=\"brb370136-sec-0030-title\">Results<\/h3>\n<p>Men with a history of cannabis use had less cognitive decline from early adulthood to late midlife compared to men without a history of cannabis use. Among cannabis users, neither age of initiation of cannabis use nor frequent use was significantly associated with a greater age-related cognitive decline.<\/p>\n<h3 class=\"wp-block-heading\" id=\"brb370136-sec-0040-title\">Discussion and Conclusions<\/h3>\n<p>In a sample of more than 5000 men followed for a mean of 44\u00a0years, we found no significant harmful effects of cannabis use on age-related cognitive decline.<\/p>\n<p> <!-- Form created by Optin Forms plugin by WPKube: create beautiful optin forms with ease! --> <!-- https:\/\/wpkube.com\/ --><!--optinforms-form5-container--> <!-- \/ Optin Forms --> <\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/neurosciencenews.com\/cognitive-decline-cannabis-28252\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Summary: A study spanning 44 years and involving over 5,000 men challenges long-held beliefs about cannabis and cognition.
