Disruption in the human microbiome causing behavioural changes in bipolar disorder.

This chapter explores the intriguing and complex relationship between the human microbiome and Bipolar Disorder (BD). The microbiome, notably the gut microbiota, has been increasingly recognised as a key performer in brain health and disease. This is due to its role in the gut-brain axis, a bidirectional communication between the gastrointestinal tract and the central nervous system. Disruptions in the gut microbiota due to factors such as diet, and stress, may influence this axis and potentially trigger or exacerbate psychiatric conditions. Hence, we investigate into the present interpretation of the microbiome's role in mental health, concentrating on its impact on mood regulation and cognitive function. Consequently, we also explore the possible mechanisms through which microbiome disruption may pay to the behavioural changes observed in BD. Further exploration understand the complex interplay between the microbiome and BD and translate these findings into effective therapeutic plans.
