Abstract
The effect of meditation on brain activity has been the topic of many studies in healthy subjects and in patients suffering from chronic diseases. These effects are either explored during meditation practice (state effects) or as a longer-term result of meditation training during the resting-state (trait). The topic of this article is to first review these findings by focusing on electroencephalography (EEG) changes in healthy subjects with or without experience in meditation. Modifications in EEG baseline rhythms, functional connectivity and advanced nonlinear parameters are discussed in regard to feasibility in clinical applications. Secondly, we provide a state-of-the-art of studies that proposed meditative practices as a complementary therapy in patients with epilepsy, in whom anxiety and depressive symptoms are prevalent. In these studies, the effects of standardized meditation programs including elements of traditional meditation practices such as mindfulness, loving-kindness and compassion are explored both at the level of psychological functioning and on the occurrence of seizures. Lastly, preliminary results are given regarding our ongoing study, the aim of which is to quantify the effects of a mindfulness self-compassion (MSC) practice on interictal and ictal epileptic activity. Feasibility, difficulties, and prospects of this study are discussed.

Weisbrod AV, Bohman LC, Ramdial KJ. From theory to practice: a novel meditation program at a global corporation. CURRENT PSYCHOLOGY 2023:1-18. [PMID: 37359588 PMCID: PMC10113717 DOI: 10.1007/s12144-023-04516-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/07/2023] [Indexed: 06/28/2023]
Abstract
Global levels of stress, worry, sadness, and anger hit new highs in recent years, and employee well-being has been identified as a necessary focus in occupational health. Developed over 6 years in a large multi-national company, the Meditation Without Expectations™ 8-week course evolved from theories to practice. The intervention teaches 8 meditation techniques in a specific order and incorporates health coaching and adult learning principles that drive impact. The wellbeing program was offered using a virtual online platform to employees in more than 30 countries during 2021-22. Its effectiveness was evaluated using established standard questions and cutting-edge consumer research methods. The descriptive study uses quantitative and qualitative analyses from more than a thousand employees. Paired t-tests are used to compare pre- and post-course survey scores. The test subjects who completed the 8-week course had significant improvements (p < 0.0001) across genders, geographies, and durations of employment, and in all measured domains of stress, mindfulness, resiliency, and empathy, whereas the comparison group did not. Advanced topics analysis is used to extract common learning objectives from unstructured text submitted by enrolled employees, which helped focus the intervention on what people need or want to learn. A proprietary artificial intelligence model is used to classify subjects' comments after completing the course, finding highly positive outcomes with potential for new habit creation due to a mental model change. A framework of characteristics that make the intervention impactful is also shared.
