Background: Psychedelics, including classic psychedelics, 3,4-methylenedioxymethamphetamine (MDMA), and ketamine, are increasingly investigated for psychiatric disorders, but their effects on sleep remain unclear. Objectives: To systematically evaluate the effects of these interventions on subjective and objective sleep outcomes and summarize sleep-related adverse events. Design: A systematic...
Chronic stress precipitates depression, yet how gut-immune-brain interactions translate stress into mood pathology remains unclear. We tested the hypothesis that stress-primed small intestinal γδ T cells drive hippocampal mitochondrial dysfunction and depression-like behavior via interleukin-17A (IL-1A). In mice exposed to chronic restraint stress (CRS), we combined behavioral assays...

Whether and how meditation benefits severe psychosis over clinically meaningful timescales remains unclear. We embedded longitudinal neuroimaging in an eight-month, parallel group randomized clinical trial (ChiCTR1800014913) of male inpatients (n=64) with schizophrenia receiving daily clinician-guided meditation plus rehabilitation versus rehabilitation alone. Meditation improved the symptoms...
This study investigated the impact of an 8-month daily-guided intensive meditation-based intervention (iMI) on persistent hallucinations/delusions and health-related quality of life (QoL) in male inpatients with schizophrenia with treatment-refractory hallucinations and delusions (TRHDs). A randomized controlled trial assigned 64 male inpatients with schizophrenia and TRHD equally to an 8-month...
Summary Background There have been mixed reports on the beneficial effects of meditation in cardiovascular disease (CVD), which is widely considered the leading cause of death worldwide. Methods To clarify the role of meditation in modulating the heart-brain axis, we implemented an extreme phenotype strategy, i.e., Tibetan monks (BMI > 30) who practised 19.20 ± 7.82 years of meditation on...
Recently, the increased prevalence of depression largely affects people's quality life and raises social suicide rate. Meanwhile, depression has been reported associated with lipid abnormalities, one of the major risks of cardiovascular disease and diabetes. 1 Hence, the improvement of lipid metabolism is of critical for depressive patients' health care. Meditation, an ancient mind training to...
