Does meditation improve cognitive performance?
The short answer
Yes — mindfulness meditation has real, measurable cognitive effects. The evidence is strongest for sustained attention, working memory, and emotional regulation. 8-week MBSR (Mindfulness-Based Stress Reduction) programmes produce measurable structural brain changes.
The key brain regions affected: the prefrontal cortex (thickening, associated with attention and self-control) and the amygdala (reduced grey matter density, associated with lower reactivity to stress). These changes appear in as little as 8 weeks of 20–40 minutes daily practice.
