Abstract: The present disclosure discloses use of a miRNA 148 cluster as a marker for diagnosing and/or treating cognitive impairment-associated diseases. The present disclosure provides use of the miRNA 148 cluster in the diagnosis and treatment of cognitive impairment-associated diseases. The expression level of the miRNA 148 cluster is detected using primers for the microRNA through cognitive impairment-associated disease models, and it is found that the expression of the miRNA 148 cluster is significantly reduced during the progression of the cognitive impairment-associated diseases. The miRNA 148 cluster is found to directly target p35 to inhibit hyperphosphorylation of Tau and can be negatively regulated by the upregulated PTEN in AD pathology. Upregulation of miRNA 148 cluster improves the cognitive dysfunction and inhibit the hyperphosphorylation of Tau in AD pathology, in which the PTEN/Akt/CREB and p35/CDK signaling pathways play a key role.
