Abstract Background There are many articles reporting that the component of intestinal microbiota implies a link to anxiety disorders (AD), and brain-gut axis is also hot topic in current research. However, specific relevance between gut AD uncertain. We aimed investigate causal relationship by using bidirectional Mendelian randomization (MR). Methods Genetic instrumental variable (IV) for were obtained from genome-wide association study (GWAS) involving 18,340 participants. Summary data derived GWAS included 158,565 cases 300,995 controls. applied inverse variance weighting (IVW) method as main analysis. To ensure robustness results, we further executed weighted median MR-Egger regression evaluate potential horizontal pleiotropy. Result discovered 16 connections bacterial traits AD.

ABSTRACT Advancing microbiome–gut–brain axis science requires systematic, rational and translational approaches to bridge the critical knowledge gaps currently preventing full exploitation of gut microbiome as a tractable therapeutic target for gastrointestinal, mental brain health. Current research is still marked by many open questions that undermine widespread application humans. For example, lack mechanistic understanding probiotic effects means it remains unclear why even apparently closely related strains exhibit different in vivo. live microbial psychobiotics, consensus on their adjunct treatments conventional neuromodulators, use unmedicated populations or at‐risk cohorts with sub‐clinical symptomatology warranted. This missing information both sides equation when treating central nervous system (CNS) conditions makes psychobiotic challenging, especially compared other pharmaceutical functional food approaches. Expediting transition from positive preclinical data proven benefits humans includes interpreting promises pitfalls animal behavioural assays, well navigating mechanism‐informed decision making select right microbe(s) job.

Abstract The establishment of a healthy microbiota, particularly during infancy, profoundly influences psychological health and neurological function through the gut‐brain axis. This review delves into intricate connections between probiotics, gut microbiome development, their impact on disorders. Biotics, live microorganisms with proven benefits, have emerged as promising intervention, critical developmental stages. Administering specific probiotic strains ( Lactobacillus species Bifidobacterium ) in infancy has shown promise preventing alleviating disorders, implications for well‐being. bidirectional communication along axis underscores potential probiotics influencing outcomes, ranging from anxiety to neurodevelopmental Additionally, this explores emerging food engineering techniques (microencapsulation, genome editing, fermentation, protein engineering, immobilization, etc.) employed preparing probiotic‐based foods, ensuring viability targeted release gastrointestinal tract.

We conducted a 12-week randomized double-blind placebo-controlled clinical trial to investigate the potential impact of Bifidobacterium bifidum (Bf-688) supplementation on attention-deficit/hyperactivity disorder (ADHD). Children with ADHD who were already receiving stable dose methylphenidate (MPH) treatment enrolled and randomly assigned two groups: one add-on Bf-688 (daily bacterial count 5 × 109 CFUs) (n = 51) other placebo 51). All participants underwent assessments using Conners’ Continuous Performance Test (CPT) Auditory Attention (CATA). Additionally, fecal samples collected at beginning (week 0) endpoint 12). Remarkably, group supplementation, but not group, exhibited significant improvements in omission errors CPT as well Hit reaction time both CATA.

The gut-brain axis (GBA) denotes the dynamic and bidirectional communication system that connects gastrointestinal tract central nervous (CNS). This review explored this axis, focusing on role of microbial diversity fitness in maintaining health preventing neurodegeneration, particularly Alzheimer's disease (AD). Gut dysbiosis, characterized by imbalance populations beneficial harmful bacteria, has been associated with increased systemic inflammation, neuroinflammation, progression AD through pathogenic mechanisms involving amyloid deposition, tauopathy, blood-brain barrier (BBB) permeability. Emerging evidence highlighted therapeutic potential probiotics, dietary interventions, intermittent fasting restoring balance, reducing minimizing neurodegenerative risks. Probiotics synbiotics are promising helping improve cognitive function metabolic health, while patterns like Mediterranean diet were linked to decreased neuroinflammation enhanced communication. Despite significant advancement, further research is needed elucidate specific strains, metabolites, influencing brain health. Future studies employing longitudinal designs advanced omics technologies essential developing targeted microbiome-based therapies for managing AD-related disorders.
