Effects of Lactobacillus brevis, Enterococcus, and Bifidobacterium longum on Neurological Disorders

Probiotics are known for providing health benefits, calling for clinical result testing on subjects. We focus on the biological effects of the following probiotics to find their potential to help neurological disorders: Lactobacillus brevis, Enterococcus, and Bifidobacterium longum. We delve into how probiotics work with the gut-brain axis—the communication center between the central and the enteric nervous system—and its effect on different neurological disorders through an extensive literature review. We found that Lactobacillus brevis helps the immune system with the potential to help with stress and anxiety disorders. Bifidobacterium longum has been shown to help age-associated disorders like Alzheimer’s and reduce severe stress levels. Enterococcus has been shown to help neuroinflammation-based diseases like Parkinson’s. Enterococcus is also shown to be more present in people with depression than without. These results bring attention to specific probiotic potential in helping neurological disorders. They will help to create more treatments and bring attention to new areas of preventing disorders.
