Microbiome

The varied community of microorganisms that live in different parts of the body, particularly the gut, is referred to as the human microbiome. These microorganisms are mostly bacteria, but they can also be viruses, fungi, and archaea. These microbial communities are vital for immune regulation, nutrition synthesis, digestion, and pathogen defense. Metagenomics research has shown that homeostasis depends on a healthy, diverse microbiome, whereas dysbiosis, or imbalances in the microbiome, is linked to a variety of illnesses, such as obesity, inflammatory bowel disease, allergies, and neuropsychiatric disorders. The field of microbiome research is growing quickly, providing new information on diet-microbe interactions, probiotic treatments, and personalized medicine.

AHA calls for lifelong brain health strategy to prevent cognitive decline

The AHA scientific statement calls for a life-course approach to brain health that integrates cognitive, emotional, behavioral, vascular, environmental, inflammatory, sleep, microbiome, and social factors. It highlights how early-life exposures, mental health, pollution, chronic inflammation, poor sleep, gut dysbiosis, and socioeconomic adversity may shape brain resilience and later-life cognitive decline.

Gut microbiome clues may help spot Parkinson’s disease in its earliest phase

Researchers found that a Parkinson’s disease-related gut microbiome pattern appears not only in people with diagnosed Parkinson’s, but also in some non-manifesting GBA1 variant carriers and a subset of healthy individuals. The findings suggest that gut microbiome changes may help flag people who are closer to Parkinson’s disease development, although longitudinal studies are still needed to confirm predictive value.
