Acute Psychological Adverse Reactions in First-Time Ritual Ayahuasca Users: A Prospective Case Series.
Journal of clinical psychopharmacology
Summary
Seven out of 40 first-time ayahuasca participants reported intense psychological challenges during ceremonies, with four meeting criteria for psychiatric disorders beforehand. Remarkably, one month later, two participants no longer exhibited symptoms, while the other two showed significant reductions. These improvements persisted at the six-month mark. However, the majority (six of seven) chose not to participate in further ceremonies, highlighting the importance of appropriate settings and guidance. This suggests that while ayahuasca can provoke acute psychological reactions, it may also lead to positive long-term outcomes.

Summary
Did you know mental training can sharpen your visual focus? Research reveals that meditation practice significantly enhances the brain's ability to discriminate visual stimuli and sustain attention. When participants engaged in meditation while facing a consistent visual task, their brain activity showed improved early sensory processing. This indicates that developing perceptual capacity beyond a task's demands positively impacts attentional control and visual processing.

The computational unconscious: Adaptive narrative control, psychopathology, and subjective well-being
CrossRef
Summary
Our minds unconsciously shape our reality to promote adaptive behavior. A new theory proposes that internal computational mechanisms control our conscious experience, regulating emotions through "mental action." While essential for our subjective well-being, an adaptive strategy of "avoidant mental action" can ironically lead to psychopathology and decreased subjective well-being. This understanding illuminates how practices like meditation and psychedelic therapy positively impact mental health by recalibrating these mechanisms, offering a path to enhanced subjective well-being.

Cognitive Aging and Long-Term Maintenance of Attentional Improvements Following Meditation Training
CrossRef
Summary
Remarkably, intensive meditation training can help preserve sharp focus for years, even as we age. Researchers explored if dedicated mental practice could offer lasting benefits against age-related cognitive decline. Following a 3-month full-time meditation program, participants' attentional improvements were partially maintained up to seven years later. Crucially, continued meditation practice significantly moderated typical age-related declines in sustained attention and response inhibition. This suggests that ongoing mental training has the potential to positively alter long-term cognitive trajectories, offering enduring benefits for brain health across the lifespan.
