Depression is a disorder characterized by significant and persistent depressed mood, cognitive impairment, impaired voluntary activity, working memory, and somatic symptoms. To determine the efficacy of Qi-based mindfulness therapy (QMT) in treating anxiety, depression, and sleep disturbances in individuals with mild-to-moderate depression. A self-controlled before-after trial was conducted....
Ketamine has been found to have rapid and potent antidepressant activity. However, despite the ubiquitous brain expression of its molecular target, the N-methyl-d-aspartate receptor (NMDAR), it was not clear whether there is a selective, primary site for ketamine's antidepressant action. We found that ketamine injection in depressive-like mice specifically blocks NMDARs in lateral habenular...
The discrepancy between the short half-life of ketamine and its long-lasting effects is due to ketamine being trapped in NMDA receptors, and its release depends on neural activity in the lateral habenula. Ketamine, an N -methyl- d -aspartate receptor (NMDAR) antagonist^ 1 , has revolutionized the treatment of depression because of its potent, rapid and sustained antidepressant effects^ 2 – 4 ....
The Buddhist construct of nonattachment is a related, yet distinct construct to mindfulness. Whereas mindfulness refers to an individual’s open, present-centred awareness of what is happening in their field of consciousness, nonattachment denotes an absence of attempts to control what is happening in their field of consciousness. The aim of the present research was to determine whether...
The rapid antidepressant effect of ketamine is arguably one of the most significant advances in the mental health field in the last half century. However, its mechanism of action has remained elusive. Here, we describe our latest discovery on how ketamine blocks N-methyl-D-aspartate receptor (NMDAR)-dependent burst firing of an "antireward" center in the brain, the lateral habenula (LHb), to...
