From probiotics to psychobiotics – the gut-brain axis in psychiatric disorders

This review by Castro-Vidal et al. (2024) underscores the crucial role of the human microbiome in the pathology of neurological and neurodegenerative illnesses, with a particular emphasis on dysbiosis (i.e., imbalance in gut bacteria) that results in gut-brain axis malfunction. Previous studies have linked dysbiosis to conditions such as Alzheimer’s disease (AD), Parkinson’s disease (PD), […]
