Ayahuasca, a tea made from the vine Banisteriopsis caapi and often combined with Psychotria viridis leaves, induces a transient altered state of consciousness marked by introspection, visions, enhanced emotions, and personal memory recall. Its psychoactive effects come from N,N-dimethyltryptamine (DMT), a 5-HT2A receptor agonist, and β-carboline alkaloids that inhibit monoamine oxidase. A growing body of evidence suggests ayahuasca may help treat substance use disorders, anxiety, and depression. The review discusses how ayahuasca intake increases mindfulness facets related to acceptance and detached observation of thoughts and emotions. The authors conclude ayahuasca shows promise for enhancing self-acceptance and enabling safe exposure to emotional events, potentially useful for impulse-related, personality, and substance use disorders and trauma, though more research is needed.

Ayahuasca, a psychotropic plant tea containing DMT and β-carboline alkaloids, increases mindfulness capacities within 24 hours of a single session. In 25 individuals, ayahuasca significantly reduced judgmental processing of experiences and inner reactivity, as measured by the Five Facets Mindfulness Questionnaire, and increased decentering ability, as measured by the Experiences Questionnaire. These changes match those seen after extensive mindfulness practice and support the tea's therapeutic potential, particularly for addiction and depression.

A single dose of ayahuasca reduced glutamate+glutamine, creatine, and N-acetylaspartate+N-acetylaspartylglutamate in the posterior cingulate cortex of 16 healthy volunteers, measured post-acutely with magnetic resonance spectroscopy. Connectivity increased between the posterior and anterior cingulate cortex, and between the anterior cingulate cortex and limbic structures in the right medial temporal lobe. Reduced glutamate+glutamine correlated with higher scores on the nonjudging subscale of the Five Facets Mindfulness Questionnaire, and increased anterior cingulate cortex-medial temporal lobe connectivity correlated with higher self-compassion scores. Post-acute neural changes predicted sustained elevations in nonjudging two months later, suggesting glutamate neurotransmission and altered default mode network connectivity underlie ayahuasca's psychological effects.

About a quarter (25.4%) of meditation practitioners report unwanted effects (UEs), which are usually temporary and do not lead to stopping practice or seeking medical help. UEs are more common during focused attention meditation, when practicing alone for more than 20 minutes, and during individual practice; body awareness practices are associated with fewer UEs. The findings come from an online survey of 342 experienced meditators (at least two months of practice), mostly women from Spain with university education. The authors recommend using standardized questionnaires to better assess these effects in future research.

Three weeks of loving-kindness and compassion meditation (LKM/CM) increased acceptance of present-moment experience in patients with borderline personality disorder, compared with mindfulness continuation training. The LKM/CM group also showed remarkable improvements in borderline symptomatology, self-criticism, and self-kindness. LKM/CM appears to be a promising complementary strategy for inclusion in mindfulness-based interventions and Dialectical Behavioural Therapy for treating core symptoms in borderline personality disorder.

A single weekend of four ayahuasca sessions improved the capacity for non-judgmental acceptance as much as an eight-week mindfulness-based stress reduction (MBSR) course, though MBSR produced larger overall gains in mindfulness. Both interventions were tested in separate groups of ten participants each. MBSR training led to greater increases in overall mindfulness scores and in a composite index sensitive to meditation practice. However, ayahuasca sessions induced comparable increases specifically in the Non-Judging subscale of the Five Facet Mindfulness Questionnaire, which measures acceptance—the ability to take a detached, less judgmental stance toward distressing thoughts and emotions. The findings suggest that a small number of ayahuasca sessions can improve acceptance as effectively as longer, costlier interventions.

A single session of ayahuasca improved emotion regulation and mindfulness-related capacities in 45 volunteers. Participants showed significant increases in observing, acting with awareness, non-judging, and non-reacting on the Five Facet Mindfulness Questionnaire, as well as improvements in decentering and reductions in emotional non-acceptance, emotional interference, and lack of control on the Difficulties in Emotion Regulation Scale. Among the 12 participants with borderline personality disorder (BPD)-like traits, improvements were seen in emotional interference and lack of control but not in mindfulness capacities. The findings suggest ayahuasca may have therapeutic potential for emotion dysregulation, including in individuals with BPD.

Ayahuasca, a psychedelic brew from Amazonia, may support mental health and boost mindfulness, but the psychological mechanisms behind its therapeutic effects are unclear. Comparing 81 ayahuasca users with 41 non-users, users scored higher on Decentering and Positive self, but not on Valued living, Life fulfillment, or measures of self in social or close relations. More experienced users (over 15 sessions) showed higher Decentering scores than less experienced ones. These findings suggest that psychological processes like Decentering could help explain ayahuasca's benefits in psychotherapy, warranting their inclusion in future studies.

A single ayahuasca ceremony led to significant improvements in self-compassion, self-criticism, and self-reassurance among 45 volunteers, with medium to large effect sizes. The findings suggest that ayahuasca may promote well-being and could have therapeutic potential for individuals with negative affect or psychopathological conditions. Most participants had used ayahuasca before. Large, controlled studies are needed to confirm these results.

Mindfulness skills training, a core part of Dialectical Behavior Therapy for borderline personality disorder, improves emotion dysregulation through specific mechanisms. In 75 outpatients who completed 10 weeks of training, greater nonjudgment of inner experience and body awareness than one's personal average predicted better emotion regulation the following week. This effect was stronger in participants with high decentering ability. A bidirectional relationship also emerged: when participants were more emotionally dysregulated than usual, they showed less gain in these mechanisms the next week. The findings suggest that targeting nonjudgment and body awareness can help improve emotion regulation difficulties in borderline personality disorder.

The Spanish versions of the Toronto Mindfulness Scale (TMS) and the State Mindfulness Scale (SMS) show adequate reliability and validity for measuring state mindfulness, though the SMS specific factors have poor reliability when controlling for the general factor. Data from six non-clinical Spanish samples (TMS n=119, SMS n=223) were analyzed using confirmatory factor analysis. The best-fitting model for the TMS was a correlated two-factor structure (curiosity and decentering). For the SMS, a bifactor structure (general factor, mindfulness of body, and mindfulness of mind) fit best. Both scales detected changes in state mindfulness after meditation practices. The patterns of correlations with measures of trait mindfulness, decentering, non-attachment, depression, anxiety, stress, affect, self-criticism, and self-reassurance were mostly as expected.

A 5-month randomized controlled trial will test whether adding Mindfulness for Health, cognitive training using the NeuronUP® platform, or their combination to usual care improves outcomes for 120 children aged 7–12 with ADHD. The study will assess ADHD symptoms, executive functions, and comorbid symptoms before and after the interventions and at a 5-month follow-up. It will also explore whether mindfulness and emotional regulation mediate clinical outcomes and whether certain characteristics predict treatment response. This is the first test of the combined intervention and of cognitive training alone in this setting, aiming to lay groundwork for a larger definitive trial.

Ayahuasca shows promise in enhancing mindfulness, with a study involving 100 participants revealing that 75% reported significant improvements in psychological well-being after use. Neuroscience insights indicate that psychedelics like ayahuasca can alter brain connectivity, fostering emotional resilience. In a separate analysis of 200 psychotherapists, 80% acknowledged incorporating mindfulness techniques into their practices, suggesting a growing acceptance of these approaches. Additionally, emerging cannabinoid research highlights potential synergies between cannabis and psychedelics in therapeutic settings, offering new avenues for mental health treatment.

Mindfulness-based cognitive therapy (MBCT) added to usual treatment reduces obsessive-compulsive disorder (OCD) symptoms more than usual treatment alone. In a trial of 68 moderately symptomatic adults, those receiving MBCT showed a 31.73% reduction on the Yale-Brown Obsessive-Compulsive Scale compared to 8.07% in the treatment-as-usual group. MBCT also lowered depressive symptoms, rumination, and perceived stress, and improved quality of life. No changes in resting-state brain connectivity were detected after treatment, but lower baseline connectivity in fronto-striatal, salience, and default mode networks predicted greater symptom reduction, suggesting a neural basis for MBCT response.

Focused attention (FA) meditation session length was associated with higher happiness and positive affect and lower depression, negative affect, and emotional overproduction. Compassion meditation (CM) session length was linked to greater positive affect, and CM practice frequency to higher happiness. Lifetime FA practice related to happiness, and lifetime open monitoring (OM) practice to lower emotional overproduction. Religious beliefs and prayer were less relevant than these meditation practices in explaining psychological adjustment. The findings suggest distinct meditation practices may differentially influence well-being through specific practice variables.

Mindfulness and positive psychology share core values such as kindness, compassion, and positive emotions, yet their integration has been underdeveloped. This paper examines the commonalities and differences between the two fields, reviews studies on how mindfulness and contemplative practices affect human well-being, and proposes future research and interventions to bridge them. Mindfulness is presented as more than a technique—it carries an implicit ethical framework that aligns with positive psychology's assumptions.

A one-month Vipassana meditation retreat, involving 8-9 hours of daily practice, a vegetarian diet, and compulsory silence, increased non-attachment, mindfulness (observing), well-being (positive affect, balanced affect), and cooperativeness in experienced meditators compared to matched controls who did not attend the retreat. Decreases occurred in describing, negative views of others, reward dependence, and self-directedness. Non-attachment partly explained changes in decentering, acting with awareness, non-reactivity, negative affect, balanced affect, self-directedness, and life satisfaction, and moderated changes in describing and positive views of others. The retreat appears to improve psychological outcomes even in experienced meditators, with non-attachment potentially enabling further gains beyond non-intensive practice.
