Teaching tape for the motor section of the unified Parkinson's disease rating scale.

We developed a teaching tape of the motor section of the Unified Parkinson's Disease Rating Scale (UPDRS) to provide investigators with a visual document of three raters' interpretations of the scoring system for each item except rigidity. The rate of agreement for the selected samples was always significant, with Kendall's coefficient of concordance W ranging between 0.97 and 0.

Cerebrospinal fluid from patients with Parkinson's disease alters the survival of dopamine neurons in mesencephalic culture.

We have previously demonstrated that extracts of striatal tissue from patients with Parkinson's disease (PD) increase the survival of dopamine neurons in mesencephalic cultures relative to striatal extracts from control patients. In the present study, ventricular cerebrospinal fluid (vCSF) from patients with PD, Alzheimer's disease (AD), and age-matched controls was similarly assessed. vCSF samples were separated into > 10-kDa and < 10-kDa fractions.

A multicenter double-blind placebo-controlled trial of pergolide as an adjunct to Sinemet in Parkinson's disease.

Three hundred and seventy-six subjects with advanced Parkinson's disease participated in a prospective, double-blind placebo-controlled study of the dopamine agonist pergolide mesylate as an adjunct to Sinemet. At 6 months, patients randomized to pergolide had a statistically significant improvement in total Parkinson's score, scores of activities of daily living, motor function, number of "off" hours, Hoehn and Yahr stage, and numerous parameters of parkinsonian function including bradykinesia, rigidity, gait, and dexterity. This benefit was obtained with the addition of a mean dose of 2.
