Dopamine and Its Function in The Development of Depressive Disorders

Abstract

Dopamine is a very important neurotransmitter that has been studied for many physiological and psychological processes, including mood regulation. This review examines the role of dopamine in the etiology of depressive disorders. It will cover the literature available on this subject and analyze existing research in the field. Some of the most important findings emphasize the link between dopamine dysregulation and symptoms of depression, focusing on its role in reward processing, motivation, and cognitive functions. In review, the pathway of dopamine introduces methodological progresses in the study of dopamine pathways. This study discusses therapeutic implications, including dopamine-targeting treatments, and despite such great progress, understanding of precise mechanisms remains incomplete.
