Clinical and preclinical studies increasingly support the antidepressant potential of several anesthetic agents, including ketamine, propofol, nitrous oxide (N2O), sevoflurane, and isoflurane. Their therapeutic effects appear to arise from the regulation of multiple interconnected systems: modulation of glutamatergic and GABAergic signaling, interaction with monoaminergic neurotransmitters...

Despite national efforts to curb the opioid crisis, the clinical and societal challenges continue to grow. FDA-approved medications for opioid use disorder (OUD) are effective but are associated with high rates of treatment discontinuation and relapse. A collection of agents with acute effects on consciousness, collectively (if variably) categorized as 'psychedelics', have emerged as potential...

Tusi, also known as "pink cocaine," has emerged across nightlife scenes in Latin America, Europe, Australia, and the United States (US). Tusi is typically a drug mixture containing ketamine and 3,4-methylenedioxymethamphetamine (MDMA). Due to tusi's inconsistent chemical makeup, surveillance and harm reduction efforts have proven difficult for researchers and consumers alike. This review...

Emerging evidence indicates that rapid-acting antidepressants (RAADs)-including ketamine and serotonergic psychedelics- may affect myelin homeostasis, aside from producing fast-onset, sustained improvements in several psychiatric disorders. A systematic search of PubMed (MEDLINE), Web of Science, Europe PMC, Directory of Open Access Journals (DOAJ), and Google Scholar was conducted up to...

Patients with schizophrenia frequently experience inadequate attribution of motivational salience, possibly related to impaired attentional processing and dysfunctional reward learning. According to the "glutamate hypothesis of schizophrenia", glutamatergic dysregulations can contribute to the emergence of psychotic symptoms and cognitive deficits in patients with schizophrenia. Blocking the...

Enhancing the early diagnosis and standardized treatment of major depressive disorder (MDD), as advocated by the National Health Commission of China, is a key priority in the mental health initiatives of the nation. To achieve this, numerous evidence-based rapid treatment centers for MDD have been established or are currently under development across the country. These centers focus on the...

It is characterized by re-experiencing trauma, avoidance, hyperarousal, and negative alterations in cognition and mood. Since its formal inclusion in the Diagnostic and Statistical Manual of Mental Disorders (DSM)-III in 1980, PTSD has...

Numerous preclinical studies have demonstrated that psychedelics promote the growth of cortical neurons in the prefrontal cortex. However, measuring psychedelic-induced structural plasticity in humans has remained a challenge. New advances in positron emission tomography imaging could facilitate the measurement of synaptic proteins in humans following psychedelic administration. Identifying a...

Traumatic brain injury (TBI) is a significant cause of mortality and disability worldwide. TBI has been associated with factors such as oxidative stress, neuroinflammation, and apoptosis, which are believed to be mediated by the N-methyl-D-aspartate (NMDA)-type glutamate receptor. Two NMDA receptor antagonists, ketamine and memantine, have shown potential in mitigating the pathophysiological...
