Schizophrenia (SZ) a chronic debilitating mental disorder affecting approximately 1% of the population globally. While understanding of pathophysiology, neuropathology and treatment have advance significantly; resistance to therapy and treatment failures necessitate the search for novel compounds like omega-3 fatty acids (OMG). This study investigated the effects of OMG on ketamine-induced...
Preclinical studies and anecdotal case reports support the potential therapeutic benefit of low-dose oral ketamine as a treatment of clinical symptoms in Rett syndrome (RTT); however, no controlled studies have been conducted in RTT to evaluate safety, tolerability and efficacy. This was a sequentially initiated, dose-escalating cohort, placebo-controlled, double blind, randomized sequence,...

This study investigates the toxic effects of ketamine on juvenile zebrafish, driven by increasing concerns over ketamine's prevalence and its potential neurotoxic effects that may disrupt behavior and metabolism. Employing a high-throughput behavior tracking system, the research analyzed the locomotor activity of 6-day post-fertilization (6 dpf) zebrafish exposed to various concentrations of...

Treatment-resistant depression responds quickly to ketamine. As an N-methyl-d-aspartate receptor (NMDAR) antagonist, ketamine may affect prefrontal cortex (PFC) neurons. Recent investigations reveal that the (R)-enantiomer is the most effective and least abuseable antidepressant. The Food and Drug Administration approves only the (S)-enantiomer for medical usage. (2R,6R)-Hydroxynorketamine...
Background and Clinical Significance: Treatment resistant psychiatric disorders affect millions of people across the globe. Ketamine has been employed as a treatment option for those with treatment resistant depression, as well as for chronic pain and alcohol use disorder. However, case presentations and research has been limited on the outcomes, and furthermore there is even less on the...
Context: Psychiatric and existential distress are common and difficult-to-treat symptoms that are frequently encountered in the palliative care setting; current treatment options are limited in efficacy and tolerability. Psychedelic-assisted therapies (PAT) have gained public and scientific interest in their potential to induce rapid and effective reductions in psychiatric and existential...
There is increasing evidence of ketamine's therapeutic potential in reducing substance use in individuals with substance use disorders. However, its effects on tobacco use disorder are unknown. We investigated the effect of a subanesthetic dose of ketamine on tobacco use. This randomized, single-blind, placebo-controlled, pilot study administered intravenous ketamine to individuals with tobacco...
Post-comatose disorders of consciousness (DoC) represent persistent neurological conditions with limited therapeutic options and a poor prognosis. Recent works advocate for exploring the effects of psychedelics to enhance brain complexity in DoC and ameliorate their consciousness. We investigated sub-anesthetic concentration of the atypical psychedelic ketamine for treating post-comatose...
Depression is a prevalent mental disorder, affecting approximately 300 million people worldwide. Despite decades of research into the underlying mechanisms of depression, a consensus remains elusive. Recent studies have implicated changes in oligodendrocytes and myelin in the pathogenesis of depression. Conventional antidepressants may alleviate symptoms within weeks of use, but approximately...
Subanesthetic ketamine is a rapidly acting antidepressant, yet the effects of ketamine on cognitive function are inconsistent. The primary objective of this study was to explore the effects of esketamine on memory function and plasma levels of nerve growth factor (NGF) in patients with depression. A total of 132 patients with depression completed six intravenous esketamine infusions (0.4 mg/kg)...
