Genetic and Molecular Insights Linking Mood Disorders and Pain

Pain has been a constant companion of humankind since the dawn of time. As a sensory perception, it is a complex, multidimensional phenomenon and an integral part of human life. It is always a personal experience influenced by numerous endogenous and exogenous factors. Since pain is an unpleasant sensation, it is always associated with an emotional component. In addition to being personal, it is also a multifaceted experience, and its perception and awareness change throughout a person’s life. Pain can lead to impulsive behavior, affecting decision-making and self-control. As a universal and complex phenomenon in the animal world, it has fascinated scientists, clinicians, and philosophers for centuries. It goes beyond simple sensory perception and encompasses a multidimensional experience that includes not only the recognition of harmful stimuli but also cognitive and behavioral responses. This multifaceted nature of pain makes it a subject of great interest and research in various fields, including neurology, psychology, and clinical medicine.
