研究：思維敏銳度可終生增強 參與度是關鍵
美國一項為期3年的研究發現，思維敏銳度並非注定隨年齡下降，人們可終生增強認知能力。研究追蹤近4000名成人，發現參與者投入大腦訓練的程度是進步的關鍵，而非年齡或教育程度。即使初始認知能力較差者，也能顯著進步。

Swiss Study Identifies New Alzheimer's Mechanism, Develops Potential Compound
A Swiss study has identified a previously underestimated mechanism in Alzheimer's disease involving the protein GRK2 and developed a compound that may disrupt it. The research, published in Cell Reports Medicine, suggests that inactive GRK2 aggregates, attaches to mitochondria, and promotes beta-amyloid production, accelerating brain damage.

Stress Impairs Spatial Navigation, German Study Finds
A German study published in PLOS Biology reveals that high stress levels, specifically elevated cortisol, impair spatial navigation abilities. Researchers found that cortisol disrupts the brain's internal GPS system, affecting grid cells in the entorhinal cortex, which are crucial for navigation. This disruption was observed regardless of the presence of external landmarks.
