Ketamine is a psychoactive substance and an N-methyl-D-aspartate (NMDA) receptor antagonist, commonly used in anesthesiology, psychiatry, and emergency medicine. Its unique dissociative properties have led to a significant global increase in recreational misuse, particularly among young adults in nightlife environments. While the medical applications of ketamine demonstrate a favorable safety...
Aim: Ketamine (KTM) is widely used in clinical settings for its anesthetic, analgesic, and antidepressant properties. However, prolonged or repeated KTM exposure can induce neurotoxicity through oxidative stress, neuroinflammation, and apoptotic mechanisms. This study investigated the neuroprotective effects of Chrysin (CHR), a natural flavonoid with potent antioxidant and anti-inflammatory...

Ketamine abuse is associated with persistent cognitive deficits and neurotoxicity, though the underlying mechanisms remain incompletely understood. While mitochondrial dysfunction and ferroptosis have been separately implicated, their causal relationship and the key molecular link in ketamine-induced hippocampal damage are unclear. Using a mouse model of ketamine-induced cognitive impairment...
Anhedonia is frequently observed in Alzheimer's disease (AD) patients and is associated with a higher risk of cognitive decline and dementia, and it potentially serve as preclinical marker and psychopathological risk factor for AD. Current antidepressants show limited efficacy in anhedonia, highlighting a critical unmet medical need. In this study, APP/PS1 mice at 8 months of age exhibited...
Antidepressant treatments, including conventional antidepressants and (es)ketamine, may reverse default mode network (DMN) resting-state functional connectivity (rsFC) alterations related to major depressive disorder (MDD). Despite these agents having distinct initial action mechanisms, both likely share downstream effects that lead to structural and functional adaptations in MDD-related neural...

Intravenous (IV) ketamine is a rapidly acting therapeutic option for the management of treatment-resistant depression and acute suicidal crisis. Unlike conventional antidepressants, its effects may occur within hours, allowing a rapid reduction in suicidal ideation and psychological distress. Its use remains specialized and requires hospital-based care with medical monitoring and a...
Cognitive impairment is a core feature of major depressive disorder (MDD) and bipolar disorder (BD). Most conventional antidepressants do not have direct and clinically relevant procognitive effects. Ketamine and esketamine are effective in treating treatment-resistant depression (TRD). Herein, this systematic review aims to evaluate the effects of both pharmacotherapeutics on cognitive...
Purpose: Ketamine and classic psychedelics have recently gained increased scientific interest regarding their role in pain management, while there is evidence that pain induces neural connectivity changes. We performed a scoping review to investigate the correlation of ketamine and classic psychedelics with pain-related neural connectivity, aiming to find potential therapeutic targets for these...
Ketamine is increasingly used in psychiatric and psychotherapeutic treatment through intravenous, intranasal, sublingual or buccal, and subcutaneous administration. Its therapeutic applications extend beyond formally diagnosed psychiatric disorders and include existential anxiety, persistent emotional distress, trauma-related suffering, psychological responses to serious illness or major life...
Background: Ketamine and esketamine have been studied as rapid-acting interventions in adults with depressive disorders and suicidal ideation, but findings vary across populations, settings, comparators, routes, and outcome measures. Aim: To examine their effects on suicidal ideation within the first 24 hours and to identify factors contributing to variability across studies. Methods: This...
