Dopamine is a catecholamine neurotransmitter, a conductive substance that regulates the central nervous system, enhances myocardial contractility, increases cardiac blood output, accelerates heart rate, mildly constricts peripheral blood vessels, and raises arterial pressure. The causes of insufficient dopamine secretion may include: 1, degeneration of organ function: such as the age of elderly patients, the degeneration of human organ function, such as brain tissue atrophy will lead to insufficient dopamine secretion; 2, taking dopamine-inhibiting drugs: when patients take drugs such as benzodiazepines and other drugs that inhibit dopamine secretion will lead to insufficient dopamine secretion; 3, heavy metal poisoning: when patients are poisoned such as manganese poisoning, it will lead to Insufficient dopamine secretion; 4, genetic factors: some patients have insufficient dopamine secretion due to genetic factors. When the patient does not have enough dopamine secretion, it will lead to depression and even depression. Therefore, when dopamine secretion is found to be insufficient, it should be actively treated, if necessary, under the guidance of a doctor to take complementary drug therapy.
