title: Concentrations of vitamins A, C and E in elderly patients with Parkinson's disease.
abstract: Concentrations of the naturally occurring antioxidant vitamins A, C and E were measured in 27 patients with Parkinson's disease and 16 age-matched control subjects, from a similarly disabled patient group. There was no significant difference in the serum concentrations of vitamins A and E in the two groups. Vitamin C was significantly higher (P < 0.05) in the Parkinson's disease group, however, the mean leucocyte vitamin C concentration in the control group was low (101 nmol/10(8) WBCS) compared to established data in healthy young individuals (119-301 nmol/10(8) WBCS). There was no correlation between the severity or duration of Parkinson's disease and concentrations of vitamins A, C and E. There is therefore no evidence from this study that a deficiency of these antioxidants contributes to the onset or progress of Parkinson's disease.
