Scientists discover hidden gut trigger behind ALS and dementia
Why it matters: This discovery offers new treatment targets for ALS and FTD, potentially helping the thousands of patients affected by these neurodegenerative diseases.
- Case Western Reserve University researchers revealed that specific gut bacteria produce inflammatory forms of glycogen (sugars) that trigger brain-damaging immune responses in ALS and FTD patients.
- Harmful gut sugars were found in 70% of the 23 ALS/FTD patients studied, compared to only one-third of healthy individuals, suggesting a strong link to disease progression.
- Reducing these bacterial sugars improved brain health in experiments, indicating a potential new treatment strategy and offering hope for identifying at-risk patients through new biomarkers.
Scientists at Case Western Reserve University have identified a hidden gut trigger for ALS and frontotemporal dementia, discovering that harmful bacterial sugars can spark immune responses that damage the brain. This breakthrough explains why some genetically at-risk individuals develop these devastating diseases while others do not, offering promising new avenues for treatment by targeting these microbial sugars.
