What is hormones is dopamine associated with?

Most recent answer: Dopamine is both a hormone and a neurotransmitter. It acts as a hormone in the blood and as a neurotransmitter in the central nervous system. It is produced in several areas of the body but mostly in the brain stem.NO...Dopamine is a monoamine neurotransmitter that is formed during the synthesis of norepinephrine and is essential to the normal functioning of the central nervous system. A reduction of dopamine in the brain is associated with the development of Parkinson's disease. Chemical formula: C8H11NO2.-www.dictionary.com-Yes, it is a hormone which, by definition, is released by endocrine cells directly into the bloodstream, to have an effect elsewhere in the body. Dopamine is release by the hypothalamus to inhibit the release of prolactin in the anterior lobe of the pituitary gland. It is also released by the adrenal medulla to constrict blood vessels as part of the 'fight or flight' reaction. Dr Sarah Brewer, author of The Human Body (Quercus).
