Oxidative stress is implicated as a major factor for nigral neuronal cell death. Metabolic failure in antioxidant mechanisms could hypothetically facilitate the chemical processes that lead to lipid peroxidation. To elucidate whether elevated lipid peroxidation rates might increase risk of developing Parkinson’s disease (PD), the Authors determined plasma levels of malondialdehyde (MDA) in 80 PD patients and 80 controls. There was a significant difference between the plasma MDA levels of PD patients and controls (7.48 ± 1.55 vs 5.1 ± 1.26 nmol/ml). Plasma MDA levels were inversely related to the age of the PD patients (r=–0.46; p <0.01) and age of onset but in the control group, no such correlation was observed between the plasma MDA and age. However, there was no significant correlation between plasma MDA levels and the duration of disease, Hoehn and Yahr stages and the Unified Parkinson’s Disease Rating Scale (UPDRS). Thus, the results suggest that high plasma lipid peroxidation rates might contribute as a risk factor for PD in West Bengal.
