Abstract Metabolic, inflammatory, and neurotrophic measures may provide complementary insight into biological heterogeneity underlying treatment-resistant depression and response to ketamine-based treatments. However, biomarker studies of ketamine treatment have focused on individual markers or biological domains, most commonly inflammatory or neurotrophic, while metabolic measures remain...

Posttraumatic stress disorder (PTSD) is a severe, often difficult-to-treat condition, highlighting the need for innovative therapies. Interventional treatments, including neuromodulation, rapid-acting pharmacotherapies such as intravenous ketamine (IV-KET) and esketamine (ESK), and emerging psychedelic-assisted psychotherapies, offer promising solutions. This systematic review evaluates the...

A sub-anesthetic dose of ketamine, an N-methyl-D-aspartate receptor (NMDAR) antagonist, produces robust antidepressant effects in treatment-resistant major depressive disorder (MDD). The mismatch negativity (MMN) is reliant on glutamatergic neurotransmission and reduced by NMDAR antagonists. The MMN may characterise the neural mechanisms underlying ketamine's effects. This study examined the...

Abstract Depression is disabling and highly prevalent. Intravenous (IV) ketamine displays rapid-onset antidepressant properties, but little is known regarding which patients are most likely to benefit, limiting personalized prescriptions. We identified randomized controlled trials of IV ketamine that recruited individuals with a relevant psychiatric diagnosis (e.g., unipolar or bipolar...
