Filter by:This study was designed to determine if preladenant (SCH 420814, MK-3814) can reduce drug-induced involuntary movements in participants with schizophrenia or schizoaffective disorder. Participants were to be evaluated for two 14-day treatment periods with a 3-week washout period between treatment periods. The primary outcome measure, Extrapyramidal Symptom Rating Score (ESRS), was to be evaluated frequently during the treatment periods.
The purposes of this study are to identify persons with rapid-onset dystonia-parkinsonism (RDP) or mutations of the RDP gene, document prevalence of the disease, and map its natural history.
The purpose of this study is to determine if low doses of apomorphine worsen the motor symptoms of Parkinson's disease.
Patients come to their doctor showing possible symptoms of a movement disorder. It is possible that these symptoms may get worse over time. There is more than one disease that can cause such symptoms. The most common movement disorder illnesses are Parkinson´s Disease and Essential Tremor. Sometimes it is difficult for doctors to make the right diagnosis because the symptoms caused by these illnesses are almost the same. On the other hand the correct treatment for Parkinson´s Disease is different from the correct treatment for Essential Tremor. This study aims to see whether having pictures of the brain taken with DaTSCAN can affect the way the doctor treats these patients and whether it can affect their quality of life directly.
The purpose of the study is to determine the sensitivity and specificity of transcranial duplex scanning (TCD) and single photon emission computer tomography (SPECT) in patients suspected of having Idiopathic Parkinson Disease (PD) or Atypical Parkinson Syndromes (APS) with as golden standard the clinical diagnosis after 2-year follow-up.
The purpose of this study is to detect possible changes in the electrical activity of the Basal Ganglia related to sedation during deep brain stimulation surgery.
We initiate a study with research grant from department of health and Taoyuan mental hospital and choose risperidone and olanzapine as study medications. We compare the incidence of using anticholinergic drugs in schizophrenic patients of Han ethnics with neuroleptic-induced acute dystonia or parkinsonism to test the hypothesis that these two medications have different EPS incidence in EPS intolerant population.
The primary aim of this study is to determine the safety and efficacy of quetiapine (Seroquel) for the treatment of psychosis and/or agitation in patients with primary dementia complicated by coexistent parkinsonism, or patients with Parkinson's disease with dementia [PDD] who have episodes of agitation or psychosis. The secondary aim is to determine the safety and tolerability, particularly the influence on parkinsonism, of quetiapine when used to treat psychosis and/or agitation in patients with dementia complicated by coexistent parkinsonism.
This program aims to investigate factors associated with development of parkinsonism or idiopathic Parkinson's Disease in an ongoing cohort of patients established in 1965 who are currently undergoing their sixth examination.
The Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke proposes to continue its cross-sectional and longitudinal studies of cerebral metabolism in frontal lobe dementias and atypical basal ganglia disorders. These studies include repeated assessments of neuropsychological and brain anatomical and metabolic function in subjects with these important and possibly related brain disorders.
