How Gut Imbalance May Be Linked to Brain Damage in Neurodegenerative Diseases

Gut dysbiosis is linked to neurodegenerative disorders such as Alzheimer's and Parkinson's disease.

• The gut-brain axis facilitates communication between the brain and the intestines through neural, hormonal, and immune pathways.
• An imbalance in the gut microbial community, known as gut dysbiosis, may contribute to neurodegeneration.
• Key mechanisms associated with neurodegeneration include protein aggregation, inflammation in the brain, disruption of protective barriers, and dysfunction of support cells in the nervous system.
• Potential therapeutic approaches could involve targeting shared pathways in various neurodegenerative diseases.
• Microbiome-directed interventions are being considered as treatment options for these conditions.
