Fish oil (FO) supplementation could cause an increase in the concentration of plasmatic free fatty acids and, consequently, could compete with pro-inflammatory arachidonic acid (ARA) derived from brain biomembranes metabolism in the cerebrospinal fluid. Essential fatty acids (EFA) (n-3) have been reported by their antioxidant and neuroprotective properties, and therefore the influence of the FO supplementation on the reserpine-induced motor disorders was studied. Wistar rats were orally treated with FO solution for 5 days, and co-treated with reserpine (R; 1 mg/kg/mL) or its vehicle for 3 days (every other day). Reserpine-induced orofacial dyskinesia and catalepsy (P < 0.05) were prevented by FO (P < 0.05). Biochemical evaluations showed that reserpine treatment increased the lipid peroxidation in the cortex and striatum (P < 0.05), while the FO supplementation prevented this oxidative effect in both brain regions (P < 0.05). Our results showed the protective role of FO in the brain lipid membranes, reinforcing the beneficial effect of n-3 fatty acids in the prevention of degenerative and motor disorders.
