Half the group took 20 milligrams of memantine daily for 12 weeks, while the other half took a  <a href=\"https:\/\/www.sciencealert.com\/what-is-a-placebo\" class=\"lar_link lar_link_outgoing\" data-linkid=\"102371\" data-postid=\"175989\" rel=\"nofollow noopener\" target=\"_self\">placebo<\/a>.<\/p>\n<p>The best responders to memantine were individuals who exhibited abnormally high glutamate levels in the pgACC.<\/p>\n<p>Among these children, adult caregivers reported memantine improving communication, interaction, and engagement with others significantly more than a placebo.<\/p>\n<p>While the results are promising, the authors of the study caution that larger  <a href=\"https:\/\/www.sciencealert.com\/clinical-trials\" class=\"lar_link lar_link_outgoing\" data-linkid=\"73032\" data-postid=\"175989\" rel=\"nofollow noopener\" target=\"_self\">clinical trials<\/a> are needed before any definitive conclusions can be made.<\/p>\n<p>Even if memantine does turn out to improve the lives of children with ASD, it may only benefit some individuals.<\/p>\n<p>Among all the participants in the recent clinical trial, just over half showed abnormally elevated glutamate levels in the pgACC.<\/p>\n<p>Previous trials, like the one from 2017, may have overlooked this significant result because they did not hone in on subsets of ASD.<\/p>\n<p> <a
