Increased plasma concentration of asymmetric dimethylarginine (ADMA) can be encountered in chronic inammatory disease, liver damage, renal failure, and multiple organ failure. In addition, an association between circulating ADMA and all‐cause mortality has been reported. Male Sprague‐Dawley rats, postnatal day (PND) 17 ± 1, received continuous ADMA infusion via an intraperitoneal pump. Spatial performance, as well as plasma and dorsal hippocampus ADMA and brain‐derived neurotrophic factor (BDNF) concentration, were examined and the effect of melatonin was tested. We found that a 4‐week continuous ADMA infusion in young rats caused spatial deficit. Furthermore, increased ADMA concentration and decreased BDNF expression were found in the plasma and dorsal hippocampus. Melatonin protected against these effects, alleviating spatial deficit and reducing the changes in plasma and dorsal hippocampus ADMA and BDNF concentration.
