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...
Abstract Background Subanesthetic ketamine infusions can elicit rapid and sustained antidepressant effects, yet the potential cognitive impact of ketamine has not been thoroughly examined. This study measured changes in objective and subjective cognitive function following repeated ketamine treatment. Methods Thirty-eight patients with treatment-resistant depression were administered cognitive...
OBJECTIVE Subanesthetic ketamine doses have been shown to have rapid yet transient antidepressant effects in patients with treatment-resistant depression, which may be prolonged by repeated administration. The purpose of this study was to evaluate the antidepressant effects of a single ketamine infusion, a series of repeated ketamine infusions, and prolongation of response with maintenance...
