Low-Dose Ketamine for Acute Suicidal Ideation: Clinical Evidence
A review of the clinical trial evidence examining low-dose ketamine as an intervention for acute suicidal ideation. This article evaluates randomized controlled trials, naturalistic studies, and emergency department protocols demonstrating ketamine's rapid anti-suicidal effects.
Sex Differences in Ketamine Treatment Response: Hormonal and Genetic Factors
Examining sex differences in ketamine treatment response, covering estrogen-NMDA interactions, progesterone modulation, genetic factors, and implications for personalized dosing.
Ketamine Effects on Sleep Architecture: Slow-Wave Sleep and REM Changes
Examining ketamine's effects on sleep architecture including slow-wave sleep enhancement, REM sleep modulation, and implications for the sleep-depression-neuroplasticity axis.
Rapid-Onset Antidepressant Mechanisms of Low-Dose Ketamine
An in-depth examination of why and how low-dose ketamine produces antidepressant effects within hours rather than weeks. This article reviews the glutamatergic hypothesis, the role of spontaneous NMDA receptor activity, and emerging theories that distinguish ketamine from conventional antidepressants.
Ketamine-Opioid System Interactions: Naltrexone Studies and Debate
Analysis of ketamine-opioid system interactions, examining the naltrexone blockade controversy, mu-receptor involvement in antidepressant effects, and implications for clinical practice.
Neuroplasticity Mechanisms in Ketamine Therapy
An in-depth exploration of how low-dose ketamine promotes neural rewiring, synaptogenesis, and dendritic spine formation. This article examines the molecular and cellular pathways through which ketamine restores synaptic connectivity in mood and pain disorders.
What Is the Response Rate for Ketamine Therapy?
Approximately 50 to 70 percent of patients with treatment-resistant depression respond to a course of low-dose ketamine infusions.
Ketamine, Neuroplasticity, and Brain-Derived Neurotrophic Factor
An exploration of the molecular and cellular mechanisms by which low-dose ketamine promotes neuroplasticity. This article reviews the role of BDNF signaling, mTOR pathway activation, and synaptogenesis in mediating ketamine's antidepressant effects.
Meta-Analyses of Low-Dose Ketamine for Treatment-Resistant Depression
A comprehensive review of major meta-analyses examining the efficacy and safety of low-dose ketamine in treatment-resistant depression. This overview synthesizes findings across multiple systematic reviews to characterize effect sizes, response rates, and durability of antidepressant outcomes.
Ketamine and Neuroinflammation: How Anti-Inflammatory Effects Support Mental Health
An evidence-based review of ketamine's anti-inflammatory mechanisms, including cytokine modulation, microglial regulation, and blood-brain barrier effects, and how these properties contribute to its antidepressant efficacy.
Ketamine and Immune Function: Immunomodulatory Effects of Low-Dose Ketamine
A research-focused review of ketamine's effects on the immune system, including its impact on innate and adaptive immunity, inflammatory cytokines, immune cell function, and implications for patients with autoimmune conditions and chronic inflammation.
How Long Do Ketamine's Antidepressant Effects Last?
The antidepressant effects of a single ketamine infusion typically last 3 to 14 days, with repeated treatments extending the duration of benefit.
