New gut-brain link: How gut mucus could help treat brain disorders

Changes in gut mucus may contribute to Alzheimer's, Parkinson's, and other neurological disorders. Researchers noted changes in types of gut mucus bacteria in those with a range of neurological disorders compared to their healthy peers. Findings suggest those with reduced gut mucus protection may be more susceptible to gastrointestinal problems.
