BACKGROUND An increased risk of aspiration pneumonia among acute ischemic stroke patients following intubation for endovascular treatment may explain the higher rates of poor outcomes among patients requiring general anesthesia compared with those performed under local sedation. METHODS Rates of aspiration pneumonia and its contribution to poor outcome at(More)
BACKGROUND To examine our eight year clinic-based experience in a Parkinson's disease expert clinical care center using clozapine as a treatment for refractory psychosis in Parkinson's disease (PD). METHODS The study was a retrospective chart review which covered eight years of clozapine registry use. Statistical T-tests, chi-square, correlations and(More)
Persons with Parkinson's disease (PD) are characterized by multifactorial gait deficits, though the factors which influence the abilities of persons with PD to adapt and store new gait patterns are unclear. The purpose of this study was to investigate the effects of dopaminergic therapy on the abilities of persons with PD to adapt and store gait parameters(More)
Tourette syndrome is a complex neurobehavioral disorder defined by multiple motor and at least 1 vocal tic, persisting over 1 year, waxing and waning in severity, and not explained by another condition. The condition may range from mild nuisance to debilitating and disabling in severity. Management includes counseling and reassurance, behavioral(More)
INTRODUCTION Weight loss is common in Parkinson's Disease (PD) and sometimes may precede the diagnosis. Weight loss is associated with multiple factors but its impact on health-related quality of life (HRQL) in PD remains unknown. We sought to investigate the factors associated with weight change and to quantify its effect on HRQL. METHODS The National(More)
INTRODUCTION Progressive supranuclear palsy (PSP) is the most common form of atypical Parkinsonism; however it is underdiagnosed and often misdiagnosed as Parkinson's disease (PD). METHODS We investigated gait initiation (GI) and gait performance in a total of 36 participants (12 PSP, 12 PD and 12 healthy age- and gender-matched controls) to gain further(More)
The non-motor symptoms of Parkinson's disease (PD) have been attracting increasing attention due to their ubiquitous nature and their often devastating effects on the quality of life. Behavioral problems in PD include dementia, depression, apathy, fatigue, anxiety, psychosis, akathisia, personality change, sleep disorders and impulse control disorders. Some(More)
Significant advances have allowed diffusion magnetic resonance imaging (MRI) to evolve into a powerful tool in the field of movement disorders that can be used to study disease states and connectivity between brain regions. Diffusion MRI is a promising potential biomarker for Parkinson's disease and other forms of parkinsonism, and may allow the distinction(More)
INTRODUCTION Even though ictal tachyarrhythmias are more common, ictal brady-asystole is more likely to be fatal, and yet is potentially preventable with pacemaker (PM) implantation. We sought to quantify the degree of association of PM placement in people with and without epilepsy, including neurological and cardiovascular cohorts. METHODS Retrospective(More)
The proceedings of the 3rd Annual Deep Brain Stimulation Think Tank summarize the most contemporary clinical, electrophysiological, imaging, and computational work on DBS for the treatment of neurological and neuropsychiatric disease. Significant innovations of the past year are emphasized. The Think Tank's contributors represent a unique multidisciplinary(More)
