420 - Ketamine treatment in geriatric depression

International Psychogeriatrics October 1, 2021 J. Leal, Maria I Lapid, Simon Kung

Treatment resistant depression can be very disabling and has a significant negative impact on a patient, their family or caregivers, and the society. There is a growing evidence on the efficacy and safety of ketamine for treatment resistant depression. Ketamine is a racemate consisting of esketamine and arketamine, is an N-methyl D-aspartate receptor antagonist and comes in different...

Parental Attitudes Toward Use of Ketamine in Adolescent Mood Disorders and Suicidality

Journal of Child and Adolescent Psychopharmacology October 1, 2021 David S. Mathai, Alexis G. McCathern, Andrew G. Guzick et al. 14 citations

Objectives: Investigation into parental decision-making processes involving ketamine is of high priority, given the necessary role of parents in consenting to treatment. In this study, we examined parental attitudes toward the emerging use of ketamine in adolescent mood disorders and suicidality. Methods: Two hundred eighty-three English-speaking parents completed an online survey using Amazon...

Ketamine-assisted psychotherapy for trauma-exposed patients in an outpatient setting: A clinical chart review study

Journal of Psychedelic Studies October 1, 2021 Alan K. Davis, Pratheek Mangini, Yitong Xin 10 citations

Abstract Trauma exposure across the lifespan produces risks for posttraumatic stress disorder (PTSD), depression, anxiety, as well as global disability in functioning. This retrospective clinical chart review is the first of its kind to assess the utility of sublingual ketamine-assisted body-centered psychotherapy in trauma-exposed patients in a real world clinic setting. De-identified clinical...

Ketamine for psychotic depression: An overview of the glutamatergic system and ketamine's mechanisms associated with antidepressant and psychotomimetic effects.

Psychiatry Research October 1, 2021 Tuyen T. Le, Joshua D. Di Vincenzo, Kayla M Teopiz et al. 26 citations

Approximately 0.35-1% of the general population is afflicted with psychotic depression at some time in their life. Psychotic depression is a subtype of major depressive disorder characterized by mood congruent hallucinations and/or delusions. Patients with psychotic depression often represent the most severe cases, with high relapse and mortality rate. Although treatment guidelines recommend a...

The effectiveness of (R)-ketamine and its mechanism of action differ from those of (S)-ketamine in a chronic unpredictable mild stress model of depression in C57BL/6J mice.

Behavioural Brain Research October 1, 2021 Anna Rafało-Ulińska, Agnieszka Pałucha-Poniewiera 46 citations

(S)-ketamine has been approved as a rapid-acting antidepressant drug (RAAD). Although ketamine has an advantage over classic antidepressants (ADs) due to its rapid action, it remains a controversial drug due to its undesirable effects. Behavioral studies indicate that another enantiomer of ketamine, namely, (R)-ketamine, has been proposed as a safer but still effective RAAD. However, these...

Ketamine in depression and electroconvulsive therapy

Current Opinion in Anaesthesiology October 1, 2021 Irene Rozet 9 citations

Purpose of review The antidepressant effect of subanesthetic doses of ketamine was recognized 20 years ago. This review briefly summarizes the current understanding of the antidepressant mechanisms and the available clinical research on the use of racemic ketamine and enantiomer esketamine for depression. Recent findings The antidepressant effect of subanesthetic doses of ketamine is currently...

The resilient phenotype elicited by ketamine against inflammatory stressors-induced depressive-like behavior is associated with NLRP3-driven signaling pathway.

Journal of Psychiatric Research September 30, 2021 A. Camargo, A. P. Dalmagro, Ingrid A V Wolin et al.

Ketamine has emerged as a prophylactic agent against depressive-like behavior induced by stress. However, the possible pro-resilience effects of ketamine against inflammatory stressors-induced depressive-like behavior and the signaling pathways associated with this response remain to be determined. Therefore, this study investigated the ability of prophylactic ketamine administration to produce...

Neuroplasticity as a convergent mechanism of ketamine and classical psychedelics

TIPS - Trends in Pharmacological Sciences September 24, 2021 Lily R. Aleksandrova, Anthony G. Phillips 255 citations

The emerging therapeutic efficacy of ketamine and classical psychedelics for depression has inspired tremendous interest in the underlying neurobiological mechanisms. We review preclinical and clinical evidence supporting neuroplasticity as a convergent downstream mechanism of action for these novel fast-acting antidepressants. Through their primary glutamate or serotonin receptor targets,...

NOVEL MANAGEMENT OF DEPRESSION USING KETAMINE IN THE INTENSIVE CARE UNIT

medRxiv Preprint Server September 23, 2021 Nirmaljot Kaur, Siva Naga S. Yarrarapu, Abhishek R. Giri et al. preprint

Background Ketamine, a dissociative anesthetic, induces remission of depression by antagonizing glutaminergic NMDA receptors. Ketamine has been used previously in outpatient setting for treatment-resistant depression, but we showcase its utility in depression management at the Intensive Care Unit (ICU).

Acute Ketamine Modulated Functional Brain Coupling and Dissociative and Affective States in Human Subjects: Interim Analyses

bioRxiv Preprint Server September 20, 2021 Laura M Hack, Katherine G. Warthen, Xue Zhang et al. 2 citations preprint

Ketamine is a non-competitive antagonist of the N-methyl-D-aspartate (NMDA) glutamate receptor that is both a drug of abuse and an FDA-approved anesthetic used off-label for treatment-resistant depression. Despite its growing clinical use for depression and pain, the relationships between the acute dissociative and affective effects of ketamine that contribute to its abuse liability and...
