Clozapine is an antipsychotic medication that is virtually free of extrapyramidal side effects. We report our successful treatment of 6 patients with idiopathic Parkinson's disease and various psychoses using clozapine on a chronic basis along with carbidopa/L-dopa.
The Driving Scenes test of the new Neuropsychological Assessment Battery (NAB; [Stern, R.A., & White, T. (2003a). Neuropsychological Assessment Battery. Lutz, FL: Psychological Assessment Resources, Inc.]) measures several aspects of visual attention thought to be important for driving ability. The current study examined the relationship between scores on… (More)
To determine whether bradykinesia in patients with Alzheimer's disease is different from the slowing of movement seen in normal aging, 25 patients with mild to moderately severe Alzheimer's disease and 25 normal controls, matched for age and sex, were studied. The measures of motor performance included two computerized tests of finger tapping, one test of… (More)
Twenty patients with asymmetric Parkinson's disease were studied in a reaction time (RT) experiment in which the performance of the more affected ("bad") hand was compared with performance of the less affected ("good") hand. Simple RT and choice RT were tested in separate blocks, and the benefit afforded by advance information in the simple RT condition… (More)
Four open-label studies have reported beneficial effects of clozapine on the tremor of idiopathic Parkinson's disease (PD). We performed a double-blind crossover trial with a 2-week washout, comparing low-dose clozapine to benztropine for the treatment of tremor in PD. Twenty-two subjects enrolled and 19 completed the study. Benztropine and clozapine were… (More)
A patient with Alzheimer's disease and mild features of parkinsonism was treated with tacrine. Tremor and gait dysfunction worsened but responded to the addition of levodopa without adversely affecting cognitive function. The implications for experimental treatment strategies of patients with combined Alzheimer's and Parkinson's disease are discussed.
BACKGROUND Positron emission tomography (PET) cameras are expensive and scarce, and the tests are non-reimbursable. A less costly and more available test such as a single photon emission computed tomography (SPECT) may be helpful in the diagnosis of early or atypical Parkinson's disease (PD) if its sensitivity is comparable to a PET scan. Altropane is an… (More)
Clozapine is an atypical neuroleptic medication that is free of parkinsonian side effects and that has been reported to ameliorate the tremor of Parkinson's disease. We report (with videotape illustration) the dramatic improvement of severe yet classic rest tremors in one elderly nonpsychotic patient with Parkinson's disease and significant improvement in… (More)
Nineteen patients with mild-to-moderate Parkinson's disease completed a 1-year open label study of a controlled release preparation of carbidopa/L-DOPA (Sinemet CR). Twelve patients were thought to have improved compared with baseline, and only one was worse. The total daily dose of L-DOPA was not significantly changed, but dosing frequency was almost… (More)
This article gives an overview of Parkinson's disease, a common neurological disorder. Inpatient care at Boston University Medical Center is discussed, stressing the importance of a comprehensive team approach to the patient with moderate to severe parkinsonism. Management of the patient during a drug holiday is discussed. A case history including a nursing… (More)
