From gut to brain: Probiotics and sex differences in the earliest stages of Alzheimer’s Disease

From gut to brain: Probiotics and sex differences in the earliest stages of alzheimer’s disease Dr. Cassandra Flynn and Dr. Qi Yuan from Memorial University of Newfoundland have conducted research indicating that probiotic supplementation can help protect the brain against early signs of Alzheimer’s disease (AD). Alzheimer’s disease (AD) affects more than 55 million people worldwide, yet it remains incurable. While most research has focused on amyloid plaques and neurofibrillary tangles that appear in later stages, growing evidence suggests that the biological changes underlying AD begin decades earlier, long before symptoms emerge. Increasing attention is now turning toward these earliest ‘preclinical’ stages, when interventions may have the greatest potential to delay disease progression.
