An 8-week yoga-based mind-body intervention, Meditation-Based Lifestyle Modification (MBLM), reduced pain intensity and improved quality of life and pain self-efficacy in most of 17 women with chronic back pain, fibromyalgia, or migraines. The largest improvement was in pain self-efficacy, followed by average pain intensity and quality of life, with a smaller effect on most severe pain. Responses varied among participants, suggesting the intervention helps many but not all. The authors call for larger controlled trials and further exploration of yoga's ethical and philosophical aspects.
Chronic users of methamphetamine and MDMA show similar deficits in conflict control and emotional processing, rather than substance-specific differences. In an emotional face-word Stroop task with anger and happy faces, both user groups exhibited smaller behavioral effects of cognitive-emotional conflict and selective impairments in processing anger, compared to amphetamine-naïve controls. These deficits were accompanied by stronger P3 event-related potential modulations, indicating altered stimulus-response mapping and decision-making. The findings suggest that chronic use of substituted amphetamines may affect noradrenergic systems, which could underlie the observed similarities. Understanding noradrenaline's role in these processes is an important direction for future research.
