Provided herein are novel tricyclic compounds as 5-HT2A receptor agonists, pharmaceutical compositions, use of such compounds in treating depression, anxiety, substance abuse and headaches, and processes for preparing such compounds.
Introduction and purpose: Depressive disorders, particularly major depressive disorder (MDD) and treatment-resistant depression (TRD), remain major causes of disability worldwide. Conventional treatments are limited by delayed onset, incomplete response, relapse, and adverse effects. This review summarizes current evidence on the efficacy, safety, and durability of psilocybin-assisted therapy...
The clinical trial NCT03866252 investigates the antidepressant effects of lysergic acid diethylamide (LSD) in 61 patients with major depressive disorder (MDD) randomized to low-dose LSD (LD-LSD; 2 × 25 μg) or moderate-to-high-dose LSD (HD-LSD; 100 μg followed by 200 μg) 4 weeks apart. Although the trial reports positive clinical outcomes, underlying mechanisms remain unclear. Here, we test...
Ketamine, including its enantiomers (S)-ketamine (esketamine) and (R)-ketamine (arketamine), has demonstrated rapid antidepressant effects in major depressive disorder (MDD) and bipolar disorder (BD), yet clinical responses vary widely, highlighting the need to identify mechanisms underlying treatment efficacy and related potential predictors. Growing evidence suggests that alterations in sleep...
Recent clinical evidence suggests that racemic 3,4-methylenedioxymethamphetamine (MDMA) might be useful for treating a range of neuropsychiatric diseases including post-traumatic stress disorder (PTSD) and depression. However, concerns about its abuse potential stemming from its monoamine releasing properties have hampered its clinical development. Thus, safer analogues of racemic MDMA with...
Ketamine has been shown to reduce depression and suicidality in individuals resistant to treatment by other drugs. Exactly how ketamine works is not known. Here, I propose a new hypothesis that involves synaptic and circuit plasticity and may lead to enhanced efficacy in treating depression as well as other conditions.
Background: Suicide is a public health crisis in the US, with limited evidence demonstrating efficacy of treatments for high-risk patients due in part to their exclusion from most clinical trials. This clinical trial evaluates the feasibility and efficacy of adjunctive cognitive behavioral therapy (CBT) with esketamine in patients with major depression and suicidal ideation (MDSI). Methods:...
Intravenous ketamine demonstrates rapid efficacy for treatment-resistant depression (TRD). However, its impact on individual depressive symptoms and whether the degree of treatment resistance moderates these effects remain unclear. This study aimed to dissect symptom-specific trajectories and examine the moderating role of the degree of treatment resistance. We conducted a post-hoc analysis of...
Treatment-resistant depression (TRD) remains a formidable challenge in psychiatry, with nearly one-third of patients with major depressive disorder (MDD) failing to respond adequately to first-line pharmacological treatments. Pathophysiology in MDD has highlighted the N-methyl-D-aspartate (NMDA) glutamatergic system as a promising therapeutic target. In 2022, the US Food and Drug Administration...
Spirituality is a crucial yet complex element of holistic nursing care, particularly when providing care for older adults with depression. In Thailand, depression poses a significant mental health challenge. Thai cultural values are deeply interwoven with individuals' beliefs, making spirituality a critical factor in addressing the care of older adults with depression. This study aimed to...
This study evaluated the effects of the Mindfulness-Based Blood Pressure Reduction (MB-BP) program on depression symptoms in individuals with elevated blood pressure (BP). Exploratory analyses examined whether childhood abuse or neglect moderated these effects. Adults with elevated BP (n = 201; ≥120/80 mmHg) were randomized to MB-BP (n = 101) or enhanced usual care (n = 100) and followed for 6...
Depression is a highly prevalent and incident mental illness. Current pharmacological therapies fail in approximately 30-40% of patients, highlighting the urgent need for novel agents with pleiotropic effects. This preclinical study aimed to identify new antidepressants and cognitive modulators among five phytocannabinoids: cannabichromene, cannabidiol, cannabidivarin, cannabigerol and...
AIM This updated systematic review and meta-analysis aimed to evaluate the effectiveness of mindfulness-based interventions (MBIs) in reducing stress, anxiety, depression and improving mindfulness among nursing students. BACKGROUND Nursing students often experience significant psychological distress due to the demanding academic and clinical environments of nursing education. MBIs have been...

Previous research has shown that preventive counseling for women at high risk of perinatal depression leads to a reduction in the development of perinatal depression and is cost-effective. Barriers of cost, transit, time, and staffing limit accessibility of these services. We examined whether a theoretical, virtual, group, social worker (SW)-led Mindfulness-Based Cognitive Therapy (MBCT)...
Knowledge workers often face high stress due to deadlines and overcommitment, which negatively impacts their well-being. They have specific characteristics and challenges, such as a tendency to work in isolation or in intense team environments, sleep deprivation, and making decisions under pressure. To support preventive measures, this study provides a comprehensive, systematic understanding of...
This study used a daily diary method to examine the temporal relationship between distress tolerance (DT), anxiety, and depression during a mindfulness-based intervention (MBI). A total of 83 participants with high emotional distress completed daily diaries of mindfulness, DT, anxiety and depression over one week before, during, and after the intervention. Linear mixed models showed significant...
Introduction: Recent rapid technological advancements and societal changes have dramatically transformed modern life, leading to a significant increase in mental health concerns. Meditation, an ancient practice, has gained considerable attention in recent years for its psychological and neurological benefits. Aim: To compare levels of depression, anxiety and stress between Meditation...

Patients with treatment‐resistant depression who received a series of treatments with ketamine or esketamine showed a substantial reduction in emergency department visits related to suicidality over a 6‐month period, a study has found. Study participants had a 56.7% response rate of depression symptoms following the acute phase of treatment.
