    "summary": "Across EEG datasets, richer activity distributions were less stable, while mild cognitive impairment and Alzheimer's reduced both measures.",
    "body_text": "Researchers modeled windowed EEG patterns as distributions, using Wasserstein distance for temporal stability and intrinsic dimensionality for complexity. Healthy aging showed higher dimensionality and lower stability, while mild cognitive impairment and Alzheimer's disease showed a joint collapse of both; posterior regions were generally richer and less stable than frontal regions. The preprint proposes a measurement framework and potential biomarker, not a diagnostic test.",
