EMG to Detect and Monitor Freezing of Gait Among People With Parkinson's Disease

Evaluation of Muscle Contraction in People With PD

The main goal of this study is to evaluate, via EMG (electromyography) system, the muscle activity in the lower limbs, to understand the contribution of the muscle activity to FOG (freezing of gait) in Parkinson's patients. The phenomenon of FOG appears in advanced cases of Parkinson's disease (PD) and can lead to an increased risk of falls. There are several approaches claiming that there is abnormal activity in the calf muscles and the freezing events in Parkinson's patients. In the clinic, monitoring FOG is done subjectively, usually through observations or through questionnaires. As a result, the information about the phenomenon may be biased and insensitive. With an electromyographic monitor (EMG), objective information about the muscular activity during normal walking and during unusual events can be obtained.

PET Imaging of Cyclooxygenases in Neurodegenerative Brain Disease

DementiaAlzheimer's Disease2 more

Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, or Huntington s disease and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-3 study visits. Participation lasts 1 week to 4 months, depending on scheduling.

Factors Associated With Falling in Parkinson's Disease

Parkinson Disease

The objective of this study will be to identify multidisciplinary fall risk factors in persons with stage 3 idiopathic Parkinson's Disease compared to age and sex-matched healthy adults. Both the relative contribution of each independent factor, as well as the interaction between these factors, will be examined. The study will include multidisciplinary assessments, including locomotor, speech, auditory, vestibular and opthalmologic assessments.

Control Cohort CTRL COH

Parkinson's Disease; Amyotrophic Lateral Sclerosis; Glioblastoma; Cancer Without Neurological Disease; Rheumatoid Polyarthritis

Autoimmune encephalitis (AE) and paraneoplastic neurological syndromes (PNS) are rare disease that could be difficult to diagnose. So it necessary to obtain numerous sample from different disease to develop more specific diagnosis kit It could be possible through the characterisation of new genetic biomarkers.

Superior Cervical Ganglion in Parkinson's Disease

Parkinson Disease

In several neurodegenerative diseases, such as Parkinson's disease, the progressive loss of neurons of monoaminergic systems leads to the development of characteristic clinical manifestations. Therefore, since the discovery that neurodegenerative phenomena are the basis of these Central Nervous System (CNS) diseases, re-innervation strategies have been studied that would allow to stop or at least slow down neurodegenerative phenomena, restoring lost catecholaminergic transmission. Cell therapy in Parkinson's disease aims to treat motor disorders, but should not affect cognitive disorders that result from pathological alterations external to CNS and affecting other transmission systems, such as noradrenergic and cholinergic. These limitations lead to the search for new approaches based on the use of different cell types, but currently these scenarios still seem far away. The theme of cerebral re-innervation in the treatment of neurodegenerative diseases is at the center of numerous translational and clinical research studies, developed according to various approaches and models, which testify to all the complexity and charm of the subject. Among the possible sources for a catecholamine reinnervation in Parkinson's disease, Superior Cervical Ganglion (SCG) could represent a valid autologous source: however, there is no functional evaluation in the literature that expresses the involvement or not of the ganglion in the neurodegenerative process. This clinical study project is the first and essential phase of a larger project aimed at verifying the possibility of autologous catecholamine reinnervation in degenerative diseases of the CNS using the peripheral catecholamine system and in particular the superior cervical ganglion (GCS). The aim of this project is to evaluate whether the peripheral catecholaminergic system, and in particular the SCG, is involved in the process of neurodegeneration. For this purpose, for an "in vivo" functional study, the suitability of the PET-CT 68Ga-PSMA examination will be studied in particular.
