Perspective Chapter: Ketamine, Depression, and Gender Bias

Abstract

Our knowledge regarding pathological and treatment resistance mechanisms involved in depression is far from understood. Sexual dimorphism in this topic is well acknowledged. However, the need to highlight sex-based discrepancies is unmet. Ketamine, the dissociative anesthetic, has emerged as a rapid antidepressant. This chapter reviewed sexual dimorphism in pharmacological and genetic models of depression, emphasizing ketamine-related antidepressant effects. Aiming by this report, we would extend our knowledge, highlight gender as one of the vital factors in examining depression in preclinical studies, and elucidate complex antidepressant effects associated with ketamine administration. Our central goal is to encourage neuroscientists to consider gender in their studies of mood disorders.
