Abstract
Dopamine (dihydroxyphenethylamine) is an organic compound from the family of Catecholamines and Phenylamines and plays an important role in the brain functioning. Dopamine is synthesized by precursors in the kidneys and brain. Dopamine is among the essential neurotransmitters in the brain, which is especially involved in pleasure and reward circuits, motivation, motor controls, functional ability, perception, sexual satisfaction, inhibition of milk secretion (lactation prevention), and nausea. This research aims to study the role of dopamine in psychopathology and biochemistry of the brain, through the document-analytical method. Review, evaluation and analysis of the previous articles imply that dopamine plays an important role in psychopathology and biochemistry of the brain. In conclusion, it is recommended for mentioned items to be empirically researched due to importance in basic and clinical research.
