TL;DR: Parasitic infections trigger a sophisticated cellular conversation in the gut that signals the brain to stop eating—a protective response that reveals how infection hijacks the gut-brain axis through epithelial cell crosstalk, acetylcholine release, and serotonin signaling. When you’re fighting an infection, appetite disappears. It feels intuitive—your body’s way of conserving energy for immune defense. …
TL;DR: Microplastics circulating in your blood may accelerate Alzheimer’s and Parkinson’s disease through six shared pathways—including blood-brain barrier breakdown, chronic inflammation, and oxidative stress. You probably know plastic pollution is everywhere. Less obvious: tiny plastic fragments are crossing into your brain, accumulating in brain tissue, and potentially triggering neurodegenerative disease. A new review in Molecular …
TL;DR: Obesity and depression form a pathophysiological trap: inflammatory cytokines and dysbiotic bacteria from obesity trigger neuroinflammation and mood disruption, while depression’s behavioral changes and HPA axis dysfunction worsen obesity. Obesity and depression are twin epidemics in the modern world, and they’re not independent. People with obesity are 1.5 to 2 times more likely to …
TL;DR: Dysbiotic bacteria in depressed adolescents cannot synthesize lysine and tryptophan, starving the brain of amino acids needed for glutamate transport and serotonin production—a causative link proven by transplanting dysbiotic bacteria into healthy rats. Depression in adolescents has tripled in the past two decades. Most treatments target a single neurotransmitter—serotonin. But a landmark multi-omics study …
Probiotics and prebiotics show potential benefits in improving symptoms and quality of life in children with ADHD, but more extensive studies are needed to confirm these effects. Highlights: Positive Impact on Functioning: Lactobacillus rhamnosus GG (LGG) supplementation improved emotional, physical, social, and school functioning in children with ADHD. Reduction in Inflammation: Synbiotic 2000 reduced markers …
Gut microbiota may influence epilepsy, but the exact mechanisms and involved microbiota are unclear, with potential treatments including ketogenic diets, probiotics, and fecal microbiota transplants being explored. Highlights: Approximately 33% of epilepsy patients are resistant to all antiseizure medications, with the role of gut microbiota in epilepsy being increasingly evident. The gut-brain axis, involving neuroendocrine, …
The naturally occurring peptide BPC 157 shows potential to treat stroke, schizophrenia symptoms, and spinal cord injury in animal models. Key facts: BPC 157 rapidly counteracted stroke damage and led to full recovery of memory, coordination and movement in rats. The peptide alleviated schizophrenia-like symptoms and catalepsy in rodent models by modulating dopamine, glutamate and …
Nutrition plays a major role in mental health, with diet quality closely linked to risk of common mental disorders like depression. This review comprehensively analyzes recent research on the impacts of nutrition on mental health and the use of nutritional interventions in treating psychiatric conditions. Key Facts: Poor diet is a major risk factor for …
Fecal microbiota transplantation (FMT) shows potential as an effective new treatment for major depressive disorder (MDD). Key facts: FMT aims to restore a healthy gut microbiome which is thought to impact mood and mental health. Studies show links between gut microbiome abnormalities and depression. FMT has successfully treated depression symptoms in animal models. A few …
Depression affects over 270 million people worldwide. New research is investigating whether manipulating gut bacteria with probiotics, prebiotics or synbiotics can help treat depression symptoms. Key Facts: Probiotics are live microorganisms that provide health benefits when consumed. Prebiotics are food for probiotics. Synbiotics contain both probiotics and prebiotics. A meta-analysis combined results from 13 studies …
