BACKGROUND Late-life depression (LLD) is a disabling disorder and antidepressants are ineffective in as many as 60% of cases. Converging evidence shows a strong correlation between LLD and subsequent risk of cardiovascular disease. There is a need for new, well-tolerated, non-pharmacological augmentation interventions that can treat depressive symptoms as well as improve heart rate variability...

OBJECTIVE: The incidence rate of major depression in adolescents reaches approximately 14%. This disorder is usually recurrent, without remission of symptoms even after pharmacological treatment, and persists throughout adult life. Since the effects of antidepressants take approximately 2 weeks to begin, new pharmacological therapies are under continuous exploration. Recent evidence suggests...

Abstract Aims We tested the age‐varying associations of cannabis use (CU) frequency and disorder (CUD) with psychotic, depressive and anxiety symptoms in adolescent and adult samples. Moderating effects of early onset (≤ 15 years) and sex were tested. Design Time‐varying effect models were used to assess the significance of concurrent associations between CU and CUD and symptoms of psychosis,...

Background: Older adults have fewer physiological reserves and are more likely to be affected by stress. Mindfulness meditation has the potential to be an effective treatment for depression, but little research has been conducted on older adults. The primary objective of this study was to evaluate depression symptom changes in older adults (55–80 years old) taking an Internet Mindfulness...

Increasing evidence supports the rapid antidepressant effect of a low-dose ketamine infusion in treatment-resistant depression (TRD). Proinflammatory cytokines play a crucial role in the pathophysiology of TRD. However, it is unknown whether the rapid antidepressant effect of ketamine is related to the rapid suppression of proinflammatory cytokines. Seventy-one patients with TRD were randomized...

Ketamine has rapid antidepressant effects on treatment-resistant depression, but the biological mechanism underpinning this effect is less clear. Our aims were to examine whether kynurenine pathway metabolites were altered by six infusions of ketamine and whether these biological factors could act as potential biomarkers to predict ketamine's antidepressant effects. Six intravenous infusions of...

Single-dose intravenous (IV) injection of ketamine has shown rapid but transient antidepressant effects. The strategy of repeated-dose ketamine infusions to maintain antidepressant effects has received little systematic study. This study was conducted to examine the efficacy and tolerability of six ketamine infusions in Chinese patients with unipolar and bipolar depression. Ninety seven...

This study tested the feasibility, acceptability, and preliminary effects of a mindfulness-based intervention with at-risk adolescents from a predominantly Hispanic/Latino community. Seven adolescents (57% female, 85% Hispanic/Latino) completed the mindfulness-based intervention, demonstrating feasibility, and reported acceptability as well as sustained improvements in depressive symptoms,...

Background Despite substantial improvements in technology and the increased demand for technology-enabled behavioral health tools among consumers, little progress has been made in easing the burden of mental illness. This may be because of the inherent challenges of conducting traditional clinical trials in a rapidly evolving technology landscape. Objective This study sought to validate the...

The symptoms of major depressive disorder (MDD) are rapidly alleviated by administration of a single dose of the glutamatergic modulator ketamine. However, few studies have investigated the potential sustained neural effects of this agent beyond immediate infusion. This study used functional magnetic resonance imaging to examine the effect of a single ketamine infusion on the resting state...
