Purpose: This study examined the links between 24-hour activity patterns (specifically, amplitude and timing of wrist activity) and the persisting qualities of clinical antidepressant response to the glutamatergic modulator ketamine. Methods: Twenty-four-hour activity patterns were compared across 5 days of 24-hour activity rhythms in patients with major depressive disorder who displayed either a brief antidepressant response (24-48 hours), a continued antidepressant response (>72 hours), or no antidepressant response to ketamine...

Depression is one of the major causes of disability worldwide. A proportion of adults with major depression fail to achieve remission with first-line treatment. Magnesium influences the neurotransmission involved in emotional processes, such as the serotonergic, noradrenergic, dopaminergic, GABAergic and glutamatergic systems. It has been reported that the mechanism of antidepressants' action is involved in the glutamatergic system. Theories about the role of magnesium ions in pathophysiology of major depressive disorder include blocking the glutamatergic N-methyl-D-aspartate receptor (NMDAR)...

Background and Aims: Shivering after spinal anesthesia is a common complication and can occur in as many as 40%-70% of patients after regional anesthesia. This shivering, apart from its physiological and hemodynamic effects, has been described as even worse than surgical pain. The aim of the study was to evaluate and compare the effectiveness of prophylactic use of intravenous (IV) ketamine, dexmedetomidine, and tramadol for prevention of shivering after spinal anesthesia. Material and Methods: Two hundred American Society of Anesthesiologists physical status I and II patients subjected to spinal anesthesia were included in the study...

Patients with advanced cancer often suffer from both severe pain and severe symptoms of depression. Use of traditional antidepressants is often limited by the short prognosis associated with advanced cancer. We present the case of a patient with neuropathic pain from advanced cancer and severe depression that responded dramatically to an intravenous infusion of ketamine resulting in decreased pain and resolution of severe depression symptoms.

Ketamine has a rapid, obvious, and persistent antidepressant effect, but its underlying molecular mechanisms remain unknown. Recently, microRNAs (miRNAs) have emerged as important modulators of ketamine's antidepressant effect. We investigated the alteration in miR-29b-3p in the brain of rats subjected to ketamine administration and chronic unpredictable mild stress (CUMS), and a sucrose preference test and forced swimming test were used to evaluate the rats' depressive-like state. We used recombination adeno-associated virus (rAAV) or lentivirus-expressing miR-29b-3p to observe the change in metabotropic glutamate receptor 4 (GRM4)...

This study explores the responses to ketamine in patients with treatment-resistant depression (TRD) using a wearable forehead electroencephalography (EEG) device. We recruited 55 outpatients with TRD who were randomized into three approximately equal- sized groups (A: 0.5 mg/kg ketamine; B: 0.2 mg/kg ketamine; and C: normal saline) under double-blind conditions. The ketamine responses were measured by EEG signals and Hamilton Depression Rating Scale (HDRS) scores. At baseline, responders showed a significantly weaker EEG theta power than did non- responders (p < 0...

The negative allosteric modulators (NAMs: L-655,708 and MRK-016) of α5 subunit-containing GABAA receptors are reported to show rapid-acting antidepressant effects in rodents. However, there are no reports comparing these NAMs and (R)‑ketamine, (R)-enantiomer of the rapid-acting antidepressant ketamine, in a chronic social defeat stress (CSDS) model. Here we measured expression of α5 GABAA receptor in the brain regions from CSDS susceptible mice and postmortem brain samples from depressed patients. Expression of α5 GABAA receptor in the prefrontal cortex and hippocampus from CSDS susceptible mice was significantly higher than that of control mice...

Depression is a common mental disorder that is associated with memory dysfunction. Ketamine has recently been demonstrated to be a rapid antidepressant. The mechanisms underlying how depression induces memory dysfunction and how ketamine relieves depressive symptoms remain poorly understood. This work compared three groups of male C57BL/6J mice: mice exposed to chronic social defeat stress (CSDS) to induce a depression-like phenotype, depression-like mice treated with ketamine, and control mice that were not exposed to CSDS or treated with ketamine...

AIM: Major depressive disorder is a common and debilitating condition with substantial economic impact. Treatment options, although effective, are aimed at relieving the symptoms with limited disease modification. Ketamine, a commonly used anesthetic, has received substantial attention as it shows rapid antidepressant effects clinically. We studied the effects of ketamine on hippocampal function and dentate gyrus proliferation in rats showing a depressive-like phenotype. METHODS: Adolescent and adult animals were prenatally exposed to the glucocorticoid analog dexamethasone, and we verified a depressive-like phenotype using behavioural tests, such as the sucrose preference...

BACKGROUND: Ketamine has been documented for its rapid antidepressant effects. However, optimal dose and delivery route have not yet been thoroughly investigated. The objectives of this study were to document the safety and test the antidepressant and antisuicidal effects of a single rapid 1-minute injection of ketamine 0.5 mg/kg in treatment-resistant depression (TRD). METHODS: Ten patients with TRD were included in an open, noncontrolled 4-week study and received a rapid intravenous dose of ketamine 0...

BACKGROUND: Ketamine is a general anaesthetic with anti-depressant effects at subanaesthetic doses. We hypothesised that intraoperative administration of ketamine would prevent or mitigate postoperative depressive symptoms in surgical patients. METHODS: We conducted an international, randomised clinical trial testing the effects of intraoperative administration of ketamine [0.5 mg kg-1 (Lo-K) or 1.0 mg kg-1 (Hi-K)] vs control [saline placebo (P)] in patients ≥60 yr old undergoing major surgery with general anaesthesia...

Previous studies have suggested that rapid reductions in depression-like behaviors are observed in response to sub-anesthetic-doses of ketamine, an N-methyl-d-aspartate receptor (NMDAR) antagonist. Neuropeptide VGF (non-acronymic) is a critical effector of depression-like behaviors and is thought to be involved in the antidepressant actions of ketamine that have been demonstrated. However, the mechanism underlying the involvement of VGF in the anti-depressant action of ketamine remains unclear. We found that single dose ketamine treatment reversed CSDS-induced depression-like behaviors and decrease of VGF in the PFC of mice...

BACKGROUND: Fatigue and depression are closely associated. The purpose of this secondary analysis was to understand the relationships between depression and improvements in specific depression domains on the anti-fatigue effects of ketamine, which we previously reported. METHODS: This secondary analysis re-evaluated data collected longitudinally from 39 patients with treatment-resistant Major Depressive Disorder (MDD) enrolled in a double-blind, randomized, placebo-controlled, crossover trial using a single intravenous infusion of ketamine hydrochloride (0...

For decades, symptoms of depression have been treated primarily with medications that target the monoaminergic brain systems, which typically take weeks to exert measurable effects and months to exert remission of symptoms. Low, subanesthetic doses of (R,S)-ketamine (ketamine) result in the rapid improvement of core depressive symptoms, including mood, anhedonia, and suicidal ideation, occurring within hours following a single administration, with relief from symptoms typically lasting up to a week. The discovery of these actions of ketamine has resulted in a reconceptualization of how depression could be more effectively treated in the future...

PURPOSE OF REVIEW: To review the pathophysiologic, epidemiologic, and clinical evidence for similarities and differences between migraine with and without aura. RECENT FINDINGS: The ICHD-3 has recently refined the diagnostic criteria for aura to include positive symptomatology, which better differentiates aura from TIA. Although substantial evidence supports cortical spreading depression as the cause of visual aura, the role (if any) of CSD in headache pain is not well understood...

BACKGROUND: Several studies indicate that ketamine has rapid antidepressant effects in patients with treatment-resistant depression (TRD). The extent to which repeated doses of ketamine (versus placebo) reduce depression in the short and long term among outpatients with TRD and chronic, current suicidal ideation remains unknown. METHODS: Twenty-six medicated outpatients with severe major depressive disorder with current, chronic suicidal ideation were randomized in a double-blind fashion to six ketamine infusions (0...

Puerarin is a traditional Chinese medicine with beneficial effects of reduced depression-like behaviors in mice with stress. Previous studies also show that puerarin can produce neuroprotective effect via activating the Akt or increased brain-derived neurotrophic factor (BDNF) expression. Interestingly, BDNF and Akt downstream target, mammalian target of rapamycin (mTOR) mediate the fast-acting antidepressant properties of ketamine. Until now, the involvement of the mTOR signaling pathway or BDNF on puerarin-induced antidepressant effect remains unknown...
