Non-alcoholic fatty liver disease (NAFLD) has been associated with depression and inadequate response to antidepressants. While ketamine has demonstrated efficacy in treating depression, its impact on pre-existing liver injury and depression remains unclear. This study aimed to evaluate the effects of ketamine treatment in a murine model of depression and liver damage, considering age-related...

Auditory deficits are a well-known symptom in neuropsychiatric disorders such as schizophrenia. The noncompetitive N-methyl-d-aspartate receptor antagonist ketamine has been used to model sensory and cognitive deficits in nonhuman primates, but its whole-brain effects remain largely unknown. Here we employed ultra-high field functional magnetic resonance imaging at 9.4 T in awake male and...

Stiff Person Syndrome (SPS) is a rare autoimmune neurological disorder characterized by progressive muscle rigidity and painful spasms. Standard treatments often yield variable responses, particularly in severe, refractory cases. This case report highlights the novel use of ketamine as an effective therapeutic agent for managing acute SPS exacerbations, underscoring its potential as a...

Alcohol use and major depressive disorder are frequently comorbid, with individuals diagnosed with a substance use disorder being nearly three times as likely to have major depression. Poor treatment responses are found for both disorders and are further complicated when they co-occur, underscoring the need for better therapies. One potential candidate is ketamine, which has been shown to have...
In this case report, we present a patient with treatment-resistant depression (TRD) and comorbid generalized anxiety disorder, eating disorder, post-traumatic stress disorder, and borderline personality disorder. Over a 10-year period, our case transitioned from adolescence to adulthood and received antidepressant monotherapy, adjunctive therapy with antipsychotics, lithium, or lamotrigine,...

Esketamine is administered intranasally in combination with at least another antidepressant in patients with treatment-resistant depression. Some of these antidepressants might affect ketamine's pharmacokinetic profile by inhibiting cytochrome-P450 (CYP450) isoforms. Our aim was to establish how different types of combined antidepressants affect serum and salivary levels of esketamine at the...
Introduction: Depression, affecting 350 million people globally, is a leading cause of disability. Common symptoms include low mood, sadness, guilt, anxiety, and suicidalthoughts. Current treatments, mostly monoamine-based antidepressants, have limitations such as delayed effects and low efficacy, with over 60% of patients not achieving lasting remission. Ketamine, an NMDA antagonist, has shown...

Ketamine-induced cystitis is an increasingly recognized complication associated with the addictive use of ketamine, a dissociative anesthetic. This article provides a comprehensive overview, focusing on its pathophysiology, clinical presentation, diagnosis, management strategies, and implications for addiction treatment. The British Association of Urological Surgeons consensus serves as a...
Ketamine is a rapid-acting treatment for treatment-resistant depression (TRD), though mechanisms related to ketamine's effects remain unclear. Blood-based neurotrophic and inflammatory factors (NIFs; e.g., brain-derived neurotrophic factor, interleukin-6) have emerged as markers potentially linked to ketamine and ketamine treatment response. In this secondary analysis of a randomized controlled...
Ketamine is an NMDA receptor antagonist, long used for its anesthetic and pain reducing properties, but has more recently demonstrated efficacy for treating depression. Evidence is also emerging for other psychiatric indications including posttraumatic stress disorder, anxiety disorders, obsessive compulsive disorder, and to support psychotherapy. In this context, there is greater demand for...
