Overview
Previous studies found that some NMDA-enhancing agents were able to improve cognitive function of patients with early-phase dementia. In addition, several drugs with antioxidant properties have been tested in clinical trials for the treatment of dementia too. Whether combined treatment of an NMDA-enhancing agent and a drug with antioxidant property can be better than an NMDA-enhancing agent alone deserves study.
