The study followed a simple, within-subject design:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Participants first received a <strong>1mg dose of psilocybin<\/strong>, considered functionally inactive<\/li>\n\n\n\n<li>Four weeks later, they received a <strong>10mg dose<\/strong><\/li>\n<\/ul>\n\n\n\n<p>Symptom changes were measured using the <strong>Yale-Brown Obsessive Compulsive Scale (Y-BOCS)<\/strong>, the gold standard for assessing OCD severity.<\/p>\n\n\n\n<p>One week after the 10mg dose, participants showed <strong>statistically and clinically significant improvements<\/strong> on the Y-BOCS \u2014 especially when compared to the low-dose condition.<\/p>\n\n\n\n<p>But the nature of that improvement was particularly revealing.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\" id=\"h-compulsions-loosen-even-if-thoughts-remain\">Compulsions Loosen, Even If Thoughts Remain<\/h4>\n\n\n\n<p>The symptom relief was driven almost entirely by reductions in <strong>compulsive behaviors<\/strong>, not obsessive thoughts.
