Major depressive disorder (MDD) is a common, serious, debilitating condition affecting 350 million people worldwide, which remains to be unsatisfactorily treated with 53% of patients still complaining of symptoms after completing their courses with the correct dosage. Ketamine, which was approved by the Food and Drug Administration in 2019, is a potential treatment option for those recalcitrant...
Subanesthetic ketamine is found to induce fast-acting and pronounced antidepressant effects, even in treatment resistant depression (TRD). However, it remains unclear how ketamine modulates neural function at the brain systems-level to regulate emotion and behavior. Here, we examined treatment-related changes in the inhibitory control network after single and repeated ketamine therapy in TRD....
BACKGROUND Acceptance/mindfulness-based interventions often focus on (a) developing dispositional mindfulness and (b) pursuing personally meaningful and valued activities. Acceptance/mindfulness-based interventions can reduce depression, but little is known about the combined effects of components or the influence of baseline variables on outcomes. This study tested whether practicing a brief...
Nitrous oxide (N2O, laughing gas) has shown early promise as a rapidly acting treatment for treatmentresistant major depression (1–3). Antidepressant effects of nitrous oxide in these studies started within 2 h and lasted up to 1 week. Due to the study design, however, it was impossible to determine whether antidepressant efficacy lasted beyond 1 week after nitrous oxide administration. There...
As the world's first primary morbidity factor, depression has a considerable impact on both an individual as well as a societal level. despite their discovery several decades ago, classical antidepressants have been shown to provide limited benefits against this condition. However, substances such as ketamine and psychedelics have recently shown promising results and even received the grade of...
Abstract Objective We examined the effects of MMIs on depression in older adults and explored the moderating effects of participant, methods, and intervention characteristics. Methods We systematically searched 15 databases through June 2019 without date restrictions using the following search terms: (mindful* OR meditat*) AND depress* AND (older adult* OR elder OR aging OR senior OR...
The objective of this study was to investigate the safety of repeated parenteral ketamine for depression. An electronic survey inquiring about the frequency of adverse events was distributed to providers of parenteral ketamine for depression. In addition, the investigators conducted a search of published studies describing six or more repeated parenteral ketamine treatments administered to...
Augmentative treatment is considered the best second-option when a first-choice drug has partial limitations, particularly by allowing antidepressant dose reduction. Considering that ketamine has significant knock-on effects, this study investigated the effects of single coadministration with subthreshold doses of ketamine plus guanosine in a corticosterone (CORT)-induced animal model of...
