The use of ketamine, a controlled dissociative anesthetic, has become more widespread in recent years with recreational/nonmedical use increasing and ketamine becoming more widely available in clinics to treat depression. We examined recent trends in adverse effects related to ketamine use. US National Poison Control data were examined, focusing on ketamine exposures among those aged ⩾13...

Objetivo: O uso de psicodélicos em psicoterapia tem sido objeto de interesse crescente na última década.Portanto, o objetivo desta revisão sistemática é examinar a literatura científica mais recente sobre os benefícios do uso de psicodélicos na promoção da saúde mental.Metodologia: Os descritores para essa pesquisa foram selecionados pela Descritores em ciência da saúde (DeCS/MeSH), da...
Repeated, long-term (weeks to months) exposure to standard antidepressant medications is required to achieve treatment efficacy. In contrast, acute ketamine quickly improves mood for an extended time. Recent work implicates that hyperpolarization-activated cyclic nucleotide-gated (HCN) channels are involved in mediating ketamine's antidepressant effects. In this study, we directly targeted HCN...
Opioid use disorder (OUD) is widely prevalent in the United States and there are high levels of comorbidity between OUD and mental illnesses, such as depression, anxiety, and posttraumatic stress disorder. Psychotherapy, in addition to medication-assisted therapy, are considered important components of long-term OUD treatment. Sudarshan Kriya Yoga (SKY) is a breathing-based mind-body...
Parkinson's disease (PD) is the second most common neurodegenerative disorder worldwide. Mindfulness and meditation therapies have been demonstrated as effective alternative treatments for patients with neurological disorders. However, the effects of mindfulness and meditation therapies on PD remain unclear. This meta-analysis investigated the effects of mindfulness and meditation therapies in...
Serotonergic psychedelics are gaining increasing interest as potential therapeutics for a range of mental illnesses. Compounds with short-lived subjective effects may be clinically useful because dosing time would be reduced, which may improve patient access. One short-acting psychedelic is 5-MeO-DMT, which has been associated with improvement in depression and anxiety symptoms in early phase...
People with terminal illnesses often experience psychological distress and associated disability. Recent clinical trial evidence has stimulated interest in the therapeutic use of psychedelics at end of life. Much uncertainty remains, however, mainly due to methodological difficulties that beset existing trials. We conducted a scoping review of pipeline clinical trials of psychedelic treatment...
Cotard's Syndrome (CS) is a rare clinical entity where patients can report nihilistic, delusional beliefs that they are already dead. Curiously, while weight loss, dehydration, and metabolic derangements have been described as discussed above, a review of the literature revealed neither a single case of a severely underweight patient nor a serious metabolic complication such as Diabetic...
The sigma-1 receptor S1R is a chaperone that resides mainly at the mitochondrion-associated endoplasmic reticulum ER membrane MAM, it is considered a “pluripotent modulator” in living systems, plays a critical role in maintaining neuronal homeostasis and acts as a dynamic pluripotent modulator in living systems. Given its specific localization at the MAM, S1R plays a major role regulating...
Introduction: Cannabis use is associated with brain functional changes in regions implicated in prominent neuroscientific theories of addiction. Emerging evidence suggests that cannabidiol (CBD) is neuroprotective and may reverse structural brain changes associated with prolonged heavy cannabis use. In this study, we examine how an ∼10-week exposure of CBD in cannabis users affected...
