Investigating Cerebellar Inhibition and Its Clinical Significance in Parkinsonian Tremor and Intention Tremor
Cerebellocerebral connection plays an important function in motor control. Nowadays it can be investigated with neuroimaging and physiological methods in humans. Cerebellar inhibition (CBI) is a phenomenon showing a physiological suppression of the motor evoked potential (MEP) evoked from the motor cortex (M1) by delivering a preceding transcranial magnetic stimulation …
Progression in Cognitive ADLs in Parkinson's Disease
Mild cognitive impairment (PD-MCI) is one of the greatest risk factors for future Parkinson's disease dementia (PDD). A recent meta-analysis found that, on average, 31% of patients with PD-MCI converted to PDD within seven years; however, 24% of patients with PD-MCI reverted back to normal cognitive function. Consequently, the false …
A Post-Approval Registry for Exablate 4000 Type 1.0 and Type 1.1 for Unilateral Pallidotomy for the Treatment of Advanced, Idiopathic Parkinson's Disease With Medication-refractory Moderate to Severe Motor Complications
This registry is a prospective, multicenter, international, single arm, observational post-approval registry with follow-up at 3, 6, and 12 months, and annually for 5 years. The proposed registry will enroll 60 subjects and will be conducted at approximately 10 centers worldwide.
Development of IPS from Donated Somatic Cells of Patients with Neurological Diseases
Human fibroblasts and possibly other human somatic cells may be reprogrammed into induced pluripotent stem (iPS) cells by the forced expression of transcription factors (1-5). The iPS cells seem to share many properties with human embryonic stem cells.Induced pluripotent stem cells potentially may be useful in the future as an …
Autoimmune Features of Neurodegenerative Disorders
This study is being conducted to better understand the role of inflammation in Parkinson's disease (PD) and Alzheimer's disease (AD). The investigators plan to recruit 30 PD, 30 AD/Amnestic Mild Cognitive Impairment (aMCI), and 60 age matched healthy controls in this study to study the role of immune response in …
Unravelling the Alteration of Brain Structure and Function in Parkinson´s Disease With Ultra-high Field MRI
Parkinson's Disease (PD) is a neurodegenerative disease characterized by a range of disabling motor- and non-motor symptoms caused by a loss of neurons in neuromodulatory brainstem nuclei. Typical motor symptoms include bradykinesia, rigidity and tremor. Non-motor symptoms are diverse and include REM sleep behaviour disorder, hyposmia, autonomic dysfunction, depression, apathy …
Longitudinal Tracking of Patients Diagnosed With Neurodegenerative Movement Disorders
The purpose of this protocol is to create an active natural history cohort of patients with degenerative movement disorders, tracked in a clinical setting with clinical rating scales and neuroimaging. The overarching rationale is that neurodegenerative diseases may be heterogeneous, complex disorders. A new way of performing clinical trials in …
Neural Correlates of Impulsivity in Idiopathic REM Sleep Behavior Disorder
This study aims to investigate the neural correlates (structural changes, functional connectivity, and structural connectivity of brain structures in prefrontal cortex and basal ganglia) of impulsivity by measuring structures and the blood-oxygen-level-dependent signal of brain in response to impulsive tasks and task-free using functional Magnetic Resonance Image method among healthy …
Pain and Autonomic Symptoms in Parkinson's Disease and Atypical Parkinsonisms
The goal of this observational study is to learn about the impact of the different types of pain and of the domains involved in the autonomic disorders of inpatients and outpatients diagnosed with Parkinson disease (PD) and multiple system atrophy (MSA) admitted to Istituti Clinici Scientifici Maugeri Centers.The main aims …
Brain Networks and Consciousness
General anesthesia (GA) is a medically induced state of unresponsiveness and unconsciousness, which millions of people experience every year. Despite its ubiquity, a clear and consistent picture of the brain circuits mediating consciousness and responsiveness has not emerged. Studies to date are limited by lack of direct recordings in human …
