| Research Abstract |
Lewy pathology in biopsied skin was found only in three of 37 patients with Parkinson disease (PD). Clinical availability of skin biopsy was limited for the diagnosis of Parkinson disease.No Lewy pathology was detected in biopsied skin from patients with multipe system atrophy (MSA). Intraepidermal nerve density (IENF) was significantly lower in patients with PD than in MSA. No significant differences in IENF were found between L-DOPA-treated and drug-naive patients with PD. The decrease in IENF did not result from L-DOPA treatment. This result suggests that the evaluation of IENF is useful to differentiate PD from MSA
