Asymmetric Dimethylarginine in Psychiatric Disorders

Asymmetric dimethylarginine (ADMA) is a derivative of the amino acid arginine that circulates in human plasma. As it is an inhibitor of nitric oxide synthase (NOS), it might have an influence on the pathophysiology of various disorders associated with low concentrations of nitric oxide, such as endothelial dysfunction and coronary heart disease, but also psychiatric disorders.
