The spleen, an important tissue for the immune system, acts as a filter for blood within the immune system. Accumulating evidence suggests that the spleen affects a number of brain functions in health and diseases via immune modulation. Systemic inflammation or chronic social defeat stress (CSDS) can cause splenomegaly in rodents. Interestingly, the new antidepressant arketamine could normalize...
Despite the considerable growth in mindfulness-based research in the field of psychosis, few attempts have been made to validate mindfulness instruments in this population. This study aimed to evaluate the factorial structure, internal consistency, construct validity, and longitudinal measurement invariance of the Mindful Attention Awareness Scale (MAAS) in a sample of individuals with...
Abstract Psychedelic compounds are on the cusp of being approved by medical regulators for treatment‐resistant mental health disorders. Following promising clinical trials, and as rates of mental ill health rise globally, psychedelic medicine presents a new paradigm for treating depression, anxiety, addiction and post‐traumatic stress disorder. The novelty of psychedelic therapies, the cultural...
Abstract Introduction Cannabis use has been associated with several psychosis outcomes including acute and persistent psychosis termed Cannabis Induced Psychotic Disorder (CIPD). The clinical and cognitive profile, course of CIPD, and the extent to which it is different from psychosis unrelated to cannabis exposure (PsyNoCan) is not clear. Methods The acute presentation and short-term (∼4...
Recent clinical and preclinical evidence points towards empathogenic and prosocial effects elicited by psychedelic compounds, notably the serotonin 5-HT 2A agonists lysergic acid diethylamide (LSD), psilocybin, N,N-Dimethyltryptamine (DMT), and their derivatives. These findings suggest a therapeutic potential of psychedelic compounds for some of the behavioural traits associated with autism...
Background and aims: Subjective well-being as a major prerequisite of health ensures mental and physical health, a long life, happiness, improved quality of life, and higher socioeconomic indices. The present study aimed to investigate the effectiveness of mindfulness-based cognitive therapy (MBCT) and acceptance and commitment therapy (ACT) on subjective well-being, psychological distress, and...
The purpose of this study was to examine whether a virtual reality plus neurofeedback (VR+NF) meditation experience (experimental condition) was more effective than a standard guided audio-only meditation (control condition) in improving mood in one hundred healthcare workers. Data collection occurred in a hospital setting between October, 2020 and March, 2021 at the height of the COVID-19...
Effective, rigorously evaluated nonpharmacological treatments for chronic pain are needed. This study compared the effectiveness of training in hypnosis (HYP) and mindfulness meditation (MM) to an active education control (ED). Veterans (N=328) were randomly assigned to 8 manualized, group-based, in-person sessions of HYP (n = 110), MM (n = 108), or ED (n = 110). Primary (average pain...
Mistuning of synaptic transmission has been proposed to underlie many psychiatric disorders, with decreased reuptake of the excitatory neurotransmitter glutamate as one contributing factor. Synaptic tuning occurs through several diverging and converging forms of plasticity. By recording evoked field postsynaptic potentials in the CA1 area in hippocampal slices, we found that inhibiting...
