The objective of this study was to examine the experience of spouses caregiving for their spouse with Parkinson's disease (PD) and to determine whether their experiences differed by stage of disease. By using a cross-sectional design and mail questionnaire data from 380 spouse caregivers across 23 sites of the Parkinson Study Group, key caregiver variables… (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.
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)
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.
IMPORTANCE Coenzyme Q10 (CoQ10), an antioxidant that supports mitochondrial function, has been shown in preclinical Parkinson disease (PD) models to reduce the loss of dopamine neurons, and was safe and well tolerated in early-phase human studies. A previous phase II study suggested possible clinical benefit. OBJECTIVE To examine whether CoQ10 could slow… (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)
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)
BACKGROUND Freezing of Gait (FOG) can be a serious problem in Parkinson's disease (PD) and is usually refractory to medical treatment. Botulinum toxin (BTX) type A has been reported to relieve FOG in small open label studies. MATERIAL/METHODS We performed a double-blind, placebo-controlled, parallel-group study using BTX-B injections on the… (More)
We conducted a multicentered, retrospective review of clozapine's (CZP) effects on a range of psychiatric, sleep, cognitive, motor, and sensory disorders in Parkinson's disease (PD). Therapeutic outcomes and adverse events were compared with varying prescribing practices at participating sites. The medical records of 172 consecutive PD patients treated with… (More)
OBJECTIVE To report the results of the 12-week, prospective, open label extension of the 4-week, multicenter, placebo-controlled, double-blind PSYCLOPS (PSYchosis and CLOzapine in the treatment of Parkinsonism) trial. This extension examined the chronic safety and efficacy of clozapine in the treatment of drug-induced psychosis in Parkinson's disease (PD).… (More)
