Brain volume changes in relation to intracortical inhibition and clinical benefit of pallidal stimulation in dystonia: a combined VBM and TMS study.
Objective: To explore the relationship between brain morphology, clinical effects of bilateral pallidal stimulation (GPi DBS) and intracortical inhibition of the motor cortex in patients…Hippocampal iron deposition in Parkinson disease and Parkinson disease with dementia/Lewy body dementia: quantitative susceptibility mapping assessments
Objective: We compared quantitative susceptibility mapping (QSM) values in the hippocampi among patients with Parkinson disease (PD) and PD with dementia (PDD)/ Lewy body dementia…Progressive microstructural abnormalities of the occipital cortex in Huntington’s disease
Objective: To investigate the rate of longitudinal microstructural alterations in the occipital cortex in patients with different stages of Huntington’s disease (HD) compared to healthy…MRI-based Brain Networks of Perfusion and Structural Abnormalities in Patients with Cerebellar Variant of Multiple System Atrophy
Objective: To identify MRI-based brain networks of cerebral perfusion and structural abnormalities in cerebellar variant of MSA. Background: MSA consists clinically of parkinsonian (MSA-P) and cerebellar (MSA-C) variants. Previous FDG PET studies have…Dystonia due to bilateral caudate hemorrhage associated with a COL4A1 mutation
Objective: Pathogenic mutations of COL4A1 are associated with young-onset stroke and porencephaly. We present a case of a 32-year-old female patient with juvenile onset right hand…Parkinson’s disease with visual hallucination: optic radiation abnormalities on phase difference-enhanced imaging (PADRE)
Objective: We assessed structural abnormalities of optic radiation (OR) in patients with Parkinson disease (PD) with dementia (PDD) and dementia with lewy bodies (DLB) by…Modeling trajectories of brain damage in progressive supranuclear palsy: A longitudinal multimodal MRI study
Objective: To explore longitudinally clinical, cognitive, and neuroimaging changes in patients with progressive supranuclear palsy syndrome (PSPs). Background: PSP is a progressive neurodegenerative disease. Longitudinal…Iron accumulation and volume loss in the extrapyramidal motor system in Friedreich ataxia: The IMAGE-FRDA study
Objective: To examine whether iron dysregulation and neurodegeneration influences the motor system outside of the cerebellum in Friedreich ataxia (FRDA). Background: FRDA is an autosomal…Hemifacial spasm: Objective computation of vertebrobasilar vascular sinuosity
Objective: To objectively compute the degree of vascular sinuosity in the vertebrobasilar arteries in hemifacial spasm (HFS) and control subjects using a case-control MRI/A approach.…Impact of white matter hyperintensity on motor compensation in Parkinson’s disease
Objective: To investigate the potential impact of white matter hyperintensity (WMH) on motor compensation in Parkinson's disease (PD). Background: WMHs, the loss of vascular integrity,…
