This study explores the psychotic-like experiences (PLEs) associated with recreational ketamine use among young adults. Ketamine, initially introduced as an anesthetic, is now widely used recreationally for its dissociative effects, raising concerns about its impact on mental health. Ten participants aged 18-24, who used ketamine recreationally multiple times a week, were assessed using the...
Anxiety disorders and treatment-resistant major depressive disorder (TRD) are often comorbid. Studies suggest ketamine has anxiolytic and antidepressant properties. To investigate if subcutaneous racemic ketamine, delivered twice weekly for 4 weeks, reduces anxiety in people with TRD. The Ketamine for Adult Depression Study was a multisite 4-week randomised, double-blind, active...
There are currently no evidence-based treatment guidelines for antisocial personality disorder (ASPD). Instead, treatment typically focuses on comorbid conditions. There is currently no literature documenting cases or research, theoretical or otherwise of using ketamine-assisted therapy or any other psychedelic therapy in cases of ASPD. In this case report, a 43-year-old man seeking...
Ketamine is a promising therapy for treatment-resistant depression due to its rapid onset, although benefits are often transitory, with patients needing maintenance therapy to prevent relapse. Most data supporting ketamine for treatment-resistant depression refers to the intravenous route of administration, leaving alternative routes lacking in data, especially as maintenance regimens....

The pathophysiology behind negative and cognitive symptoms of schizophrenia is not well understood, thus limiting the effectiveness of treatment on these symptoms. Developing reliable animal model of schizophrenia is vital to advance our understanding on the neurobiological basis of the disorder. Double hit is used to refer to the use of two schizophrenia inducing interventions viz ketamine...
Ketamine is an NMDA receptor antagonist that has antidepressant and anesthetic properties. At subanesthetic doses, ketamine induces transient psychosis in humans, and is used to model psychosis in experimental animals. In rodents, subanesthetic doses of ketamine increase the power of high-frequency oscillations (HFO, > 100 Hz) in the electroencephalogram (EEG), a frequency band linked to...
Mental illnesses like bipolar disorder and schizophrenia often present psychotic symptoms. Current antipsychotic medications, including clozapine, can cause serious side effects. This study investigates the potential therapeutic effects of the cholinesterase inhibitor donepezil compared to clozapine in a ketamine-induced psychosis model in rats. Forty adult male albino rats were divided into...
Abstract Depression is the leading cause of suicide, and antidepressants and modified electroconvulsive therapy (mECT) are the preferred treatment modalities. Ketamine is an established anesthetic agent and evidence for its use in depression is evolving. Here, we discuss the experience of treating severe depression with intravenous (IV) ketamine. A patient in his mid-forties presented with a...
Major depressive disorder (MDD) significantly impairs adolescents' development, with increasing rates of treatment resistance and suicide risk. Ketamine has emerged as a promising, rapid-acting antidepressant in adults, but its efficacy and safety in adolescents remain unclear. This systematic review and meta-analysis aimed to evaluate short-term outcomes of ketamine administration in youth...
Methemoglobinemia is defined as an increase in methemoglobin of > 2% of hemoglobin. Ketamine is increasingly used for severe depression. To our knowledge, a patient with mitochondrial encephalopathy, lactic acidosis and stroke‐like episodes (MELAS) who died suddenly and unexpectedly 1–12 h after ketamine infusion with high postmortem methemoglobin has not yet been reported. The patient was a...
