Deanol and placebo were administered to 10 parkinsonian patients with levodopa-induced dyskinesias in a double-blind, crossover fashion. Deanol and placebo did not differ significantly in their effects on dyskinesias. The reported properties of deanol seem to be attributable to a placebo effect. There was no correlation with the results of the physostigmine test. Despite these disappointing results deanol remains intriguing, because in individual cases remarkable improvements on dyskinesias are reported.
