The glutamatergic system is the primary excitatory pathway within the CNS and is responsible for cognition, memory, learning, emotion, and mood. Because of its significant importance in widespread nervous system function, it is tightly regulated through multiple mechanisms, such as glutamate recycling, microglial interactions, and inflammatory pathways. Imbalance within the glutamatergic system...

Thirty percent of depressed patients are treatment resistant (TRD) suggesting the need of new therapeutic strategy. Recently, it has been shown that ketamine, an anesthetic agent with dissociative effects, has potent and rapid antidepressant properties. Ketamine is a ionotropic glutamatergic NMDA antagonist that inhibits gabaergic neurons. Its antidepressant effect peaks at 24 h post-treatment....

Neuroinflammation plays a key role in the pathogenesis of major depressive disorder (MDD), including treatment-resistant depression (TRD). Patients with TRD have higher levels of inflammatory biomarkers compared with responders to antidepressants. Multiple lines of evidence suggest that the gut-microbiota-brain axis via the vagus nerve plays a key role in neuroinflammation. Preclinical and...

The following paper described two cases of patients with catatonic depression in bipolar disorder (BD) referred to our electroconvulsive therapy (ECT) service. Both were deemed not medically fit for ECT, and were, instead, treated with intravenous (IV) ketamine. Both responded with a resolution of symptoms, returning to baseline level of functioning. During the COVID-19 pandemic, given the...
