Effective treatments for prolonged disorders of consciousness (pDoC) remain limited. Grounded in the entropic brain hypothesis-that psychedelic agents facilitate consciousness recovery by increasing brain complexity-this study investigated esketamine, a nonclassical psychedelic drug, and its effects on electroencephalographic (EEG) neurophysiological metrics in pDoC patients. In this...

Background: Ketamine, a commonly used nonbarbiturate anesthetic drug, possesses antidepressant properties at subanesthetic doses; however, the underlying mechanisms remain unclear. Materials and Methods: The analgesic and antidepressant effects of ketamine were explored using a complete Freund adjuvant (CFA)-induced peripheral inflammatory pain model in vivo. Mice were first divided into sham...

K anesthesia was introduced about half a century ago. In recent decades, this drug, in subanesthetic doses, has also demonstrated efficacy for off-label indications including treating acute and chronic pain, treating agitation, treating depression, and inducing sedation. Thus, there are studies of subanesthetic dosing with ketamine for treating pain in emergency medicine settings, treating...

Background: Although interest in ketamine use during electroconvulsive therapy (ECT) has increased, studies have been equivocal with regard to its efficacy. The aims of this clinical trial were to evaluate ketamine’s antidepressive effects in ECT as a primary anesthetic, determine ketamine’s tolerability when compared with standard anesthesia, and determine if plasma brain-derived neurotrophic...
