But the compound psi-GSH provides the glyoxalase system the fuel it needs to destroy destructive oxidized sugar metabolites that \u2013 in Alzheimer&#8217;s models \u2013 converts normal brain amyloid protein into the abnormal form that produces Alzheimer&#8217;s.<\/p>\n<p>When given to mice genetically predisposed to develop Alzheimer&#8217;s disease, psi-GSH reduced the buildup of abnormal amyloid beta protein in the brain. The buildup of this protein is a well-known feature of Alzheimer&#8217;s, ultimately found in the form of plaques and tangles in the brain associated with the condition.<\/p>\n<p>After being administered with psi-GSH for 11 weeks, cognitive capabilities such as memory and chemical brain health indicators in Alzheimer&#8217;s-predisposed mice remained intact.<\/p>\n<p>For example, <strong>the treated mice retained complete memory in a standard Alzheimer&#8217;s maze test while the untreated mice lost significant memory and ability to negotiate the maze, indications consistent with symptoms of advanced Alzheimer&#8217;s<\/strong>.<\/p>\n<p>In addition, the treated mice were devoid of brain plaques while the untreated mice had significant plaque formation.<\/p>\n<p>Preliminary studies indicated no observed toxicity to the brain or other vital organs from psi-GSH.<\/p><\/blockquote>\n<!-- AddThis Advanced Settings generic via filter on the_content --><!-- AddThis Share Buttons generic via filter on the_content -->","protected":false},"excerpt":{"rendered":"<p>From the University of Minnesota Academic Health Center press release via EurekAlert!: Researchers at the University of Minnesota&#8217;s Center for Drug Design have developed a synthetic compound that, in a&#8230; <a class=\"read-more-link\" href=\"https:\/\/therapytoronto.ca\/news\/2012\/12\/researchers-find-new-target-for-alzheimers-drug-development\/\">Read more &raquo;<\/a><!-- AddThis Advanced Settings generic via filter on get_the_excerpt --><!-- AddThis Share Buttons generic via filter on get_the_excerpt --><\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[321,6],"tags":[195,42,18,194],"_links":{"self":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8849"}],"collection":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/comments?post=8849"}],"version-history":[{"count":4,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8849\/revisions"}],"predecessor-version":[{"id":8935,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/posts\/8849\/revisions\/8935"}],"wp:attachment":[{"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/media?parent=8849"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/categories?post=8849"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/therapytoronto.ca\/news\/wp-json\/wp\/v2\/tags?post=8849"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
