A Scoping Review and Preliminary Illustrative Analysis of Biomarkers in Stress-Related Psychiatric Illness: Diagnostic and Prognostic Implications

Stress is the body's response to any changes that might place it under mental, emotional, or physical strain and could either demand attention or prompt action. A stress reaction can be brought on by both internal and external factors. The conditions, demands, issues, and expectations you deal with every day are all regarded as external influences, as are your physical surroundings, your job, your contacts with others, your family, and all other related factors. The ability of your body to respond to and handle external stimuli depends on internal factors. Your ability to handle stress is influenced internally by your food habits, level of general health and fitness, mental health, and the amount of sleep and rest you get. Such demanding conditions could affect how certain stress hormone levels are regulated. Biomarkers such as mGlu2/3, 5-hydroxyindoleacetic acid (5-HIAA), serum alpha-amylase, amygdala reactivity, neuropeptide Y (NPY), heat shock proteins, cortisol, and catecholamines are used to assess the hormone imbalance. Disease prevention, early detection, and therapy are all possible uses for biomarkers. In this review, we looked at a wide range of stress-related biomarkers that might cause different psychiatric illnesses and how those conditions can, over time, alter a person's lifestyle
