T2DM mice induced by a high\u2010fat diet combined with streptozotocin were treated with ethanol extract of <jats:italic>A. tsao\u2010ko<\/jats:italic> (EEAT) for 8\u2009weeks. The cognitive function was evaluated by the Morris water maze (MWM) test, open field test (OFT), and novel object recognition test (NORT). Hippocampus and colon tissues were used for histopathology, biochemical assays, or protein expression analysis. Additionally, fecal samples were subjected to 16S rRNA gene sequencing and short\u2010chain fatty acids (SCFAs) detection.<\/jats:p><\/jats:sec><jats:sec><jats:title>Key Results<\/jats:title><jats:p>The findings demonstrated that EEAT significantly reversed glucose metabolism disorders and cognitive deficits in T2DM mice. It promoted the protein expression of the CREB\/BDNF\/TrkB pathway and reduced hippocampal inflammatory responses, thereby improving neuronal damage. It inhibited the loss of colonic tight junction proteins, decreased the levels of inflammatory factors in the colon, and also reshaped the gut microbiota and increased SCFAs. Notably, Spearman's correlation analysis indicated that the <jats:italic>Lachnospiraceae NK4A136 group<\/jats:italic>, <jats:italic>Ruminococcaceae UCG\u2010014<\/jats:italic>,
