腸道細菌可能與漸凍症和失智症有關
Gut Bacteria May Be Linked to ALS and Dementia
近期的科學突破改變了我們對肌萎縮性側索硬化症（ALS）與額顳葉失智症（FTD）等神經退化疾病的看法。
Recent scientific breakthroughs have shifted our perspective on neurodegenerative diseases like Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD).
這些疾病過往被視為純粹由大腦引發，現在則透過「腦腸軸」的角度來理解。
Traditionally viewed as strictly brain-centric, these conditions are now being understood through the lens of the gut-brain axis.
凱斯西儲大學（Case Western Reserve University）於2026年發表的標誌性研究顯示，某些腸道細菌會產生發炎性醣類。
A landmark 2026 study from Case Western Reserve University revealed that certain gut bacteria produce inflammatory sugars.
這項發現解開了一樁長期未解的謎團：為何攜帶相同基因突變（如C9orf72突變）的患者，臨床表現卻大不相同。
This discovery addresses a long-standing mystery: why people with the same genetic mutations, like the C9orf72 mutation, have different clinical outcomes.
事實上，70%的ALS/FTD患者體內這種醣類水平高到危險的地步，相較之下，健康人群中僅有三分之一有此現象。
In fact, 70% of ALS/FTD patients exhibited dangerous levels of these sugars compared to one-third of healthy individuals.
這種系統觀點顯示，常被稱為「第二大腦」的腸道，其實正在影響我們的中樞神經系統。
This systemic view suggests that the gut—often termed the "second brain"—influences our central nervous system.
