L-Dopa and Brain Serotonin System Dysfunction
... Another consequence of this “off-target” effect is that L-dopa can become toxic to 5-HT systems. One mechanism of 5-HT neurotoxicity appears to be related to oxidative stress produced by L-dopa-induced supraphysiologic concentrations of dopamine. Dopamine has long been known to be a potent oxidant [ ...
