A research team led by Professor Oh Yong-Seok of the Department of Brain Sciences at the Daegu Gyeongbuk Institute of Science and Technology has, for the first time, identified the key cause of the "treatment delay" phenomenon, in which antidepressant medications often take several weeks or longer to produce therapeutic effects after administration. The research is published in the journal Molecular Psychiatry.
