title: Selegiline as primary treatment in early phase Parkinson's disease--an interim report.
abstract: We are carrying out a double-blind parallel trial comparing the effect of selegiline monotherapy and placebo in de novo parkinsonian patients. Fifty-six patients (28 in both groups) are included in the trial. This interim analysis reports the results of the first 52 evaluable patients who have had at least one follow-up visit after entering the trial. The efficacy of treatment was assessed using the Columbia University Rating Scale, the North-Western University Disability Scale and the Webster Rating Scale and followed until the addition of levodopa therapy became necessary. The data were analysed at follow-up times of up to twelve months (34 patients evaluable at the end of the period). The overall disability scores of all the rating scales used were significantly smaller in the selegiline group than in the placebo group. Levodopa treatment had become necessary in 12 patients (46%) in the selegiline group and in 14 patients (54%) in the placebo group. The side-effects were mild and similar in both treatment groups. According to the present results selegiline monotherapy seems to have therapeutic efficacy in the early phase of Parkinson's disease. Whether selegiline is able to slow down the progression of Parkinson's disease needs further clarification.
