Management of Parkinson's Disease

Combined Therapy with Levodopa and Thalamotomy

Abstract

An increasing number of parkinsonian patients in whom levodopa fails to relieve tremor are being referred for thalamotomy. The literature suggests that in as many as 50 percent of patients treated with levodopa, there is no relief of tremor because of refractoriness to the medication or intractable side effects which limit dosage. Thalamotomy abolishes contralateral tremor in 90 percent of patients, with an associated mortality rate of 1 to 2 percent and morbidity of 6 percent. The relative merits and complications of levodopa and thalamotomy were reviewed and a therapeutic regimen designed in which the two approaches to treatment are combined to most effectively deal with all the symptoms of parkinsonism.
