Low-grade inflammation (LGI) contributes to resistance against traditional antidepressants. However, whether the antidepressant and antisuicidal effects of ketamine on patients with treatment-resistant depression (TRD) differ between those with LGI and those without LGI remains unknown.This study included 167 patients with TRD, among whom 46 had LGI and 121 did not have LGI. The patients...
The rising prevalence of depression, with its associated suicide risk, demands effective fast-acting treatments. Ketamine has emerged as promising, demonstrating rapid antidepressant effects. While early studies show swift mood improvements, its precise mechanisms remain unclear. This article aims to compile and synthesize the literature on ketamine's molecular actions. Ketamine primarily works...
Many people living with HIV (PLWH) experience death anxiety and depression, which may impact negatively on their health-related quality of life (HRQoL). Mindfulness is a psychological resource that protects against death anxiety and depression and promotes HRQoL. Although a direct association among these variables exist, little is known about their interactive effect. This study examined the...
Background/Objectives: Psychotherapy and antidepressants are the standard treatment for depression during pregnancy or postpartum. However, several new treatments for depression represent major advances and paradigm changes. This commentary highlights some innovative treatment options that are on the horizon. Most of these modalities are promising, and most are non-invasive. Many of these...
Background: Ketamine has demonstrated both rapid and sustained efficacy in treating depression, especially in treatment-resistant cases. However, concerns regarding the addictive potential of ketamine during long-term depression treatment persist among clinicians. Aim: This review aimed to summarise the evidence on addiction phenomena associated with ketamine treatment of depression. Methods: A...
Fatigue is a multidimensional condition that may overlap with depression. Initial studies found that fatigue responds in only a limited way to standard monoaminergic antidepressants and mood stabilizers but does respond positively to intravenous (IV) racemic (R,S)-ketamine (ketamine). However, IV ketamine's use is limited by cost and access barriers. To date, no study has evaluated intranasal...
Persons with Major Depressive Disorder (MDD), notably treatment-resistant depression (TRD), are differentially affected by type 2 diabetes mellitus and associated morbidity. Ketamine is highly efficacious in the treatment of adults living with MDD, notably TRD. Herein, we sought to determine the effect of ketamine on metabolic parameters in animal stress paradigms and human studies. We...
Major depressive disorder (MDD) is highly prevalent in youth. Conventional treatment paradigms primarily involve selective serotonin reuptake inhibitors (SSRIs) and psychotherapy, yet a significant proportion of this population exhibits treatment-resistant depression (TRD). In adults, interventional therapies like Electroconvulsive Therapy (ECT), repetitive Transcranial Magnetic Stimulation...
Chronic restrain stress (CRS) induces depression-like behaviors and demyelination in the brain; however, the relationship between these depression-like behaviors and demyelination remains unclear. Arketamine, the (R)-enantiomer of ketamine, has shown rapid antidepressant-like effects in CRS-exposed mice. We examined whether arketamine can improve both depression-like behaviors and demyelination...
