Probiotics and Disease: A Comprehensive Summary-Part 1, Mental and Neurological Health

This article series provides a literature review of the disease-specific probiotic strains studied in published clinical trials in humans and animals. The goal of the series is to provide clinically useful tools. The table designs allow for quick access to supportive data related to disease states and will be helpful as a guide for both researchers and clinicians. This first article (part 1) focuses on mental health and neurological conditions. Future articles in this series will review conditions related to cardiometabolic and fatigue syndromes; ear, nose, throat, respiratory, and infectious diseases; immune and dermatological conditions; cancer, gastrointestinal and genitourinary; followed by an article focused on food-based probiotic strains and nutritional supplements. This literature review is specific to condition, probiotic, and strain and also lists currently available products and foods in which these probiotics can be found. In part 1, we explore the role of probiotics in balancing mental health and neurological issues. Conditions in mental health include anxiety, depression, attention-deficit/hyperactivity disorder, and autism. Neurological conditions include age-related cognitive decline, hepatic encephalopathy, cerebral ischemia and reperfusion, traumatic brain injury, and multiple sclerosis.
