Click here to view original web page at Nose vs. Gut: Unraveling Parkinson’s Toxic Origins
Summary: A pivotal hypothesis paper challenges existing theories on Parkinson’s disease origins, proposing environmental toxicants as key culprits. This study suggests that Parkinson’s can start from the brain’s smell center or the gut, influenced by inhaled or ingested toxins. It introduces a unified model linking environmental factors like pesticides […]

Summary: Researchers employing computational models have made a significant leap in understanding the aggregation of alpha-synuclein protein, crucial in Parkinson’s disease development. This study marks the first to map the molecular dynamics of these proteins in detail, revealing how environmental factors like molecule crowding and ionic changes enhance aggregation. […]
Summary: Researchers linked midlife stress and childhood trauma to an increased risk of Alzheimer’s disease and neuroinflammation. Analyzing 1,290 volunteers, researchers found that stressful life events, especially during midlife, correlate with higher levels of β-amyloid protein, crucial in Alzheimer’s development, and that childhood stress is associated with later life […]
