Parkinson Disease

Parkinson Disease is one of the most common neurodegenerative illnesses. First degree relatives of Parkinson patient are in high risk for developing the disease. We will try to detect early changes in brain metabolism before the appearance of Parkinson symptoms. Participants: first degree relatives of diagnosed Parkinson patients that carry a gene mutation in either LRRK2 or GBA genes. The examination results will be given to the participants by a doctor from the neurology department.

A Longitudinal Study in Parkinson's Disease (PD) Patients

Parkinson's Disease

This is a longitudinal study in patients with Parkinson's Disease (PD) carriers of a genetic mutation - substitution of gly with ser in position 2019 (G2019S) in the leucine-rich repeat kinase 2 (LRRK2) gene. The purpose of this study is to explore the association between genetic mutations in the known genes and their influence on disease manifestation over few years of follow up

Ancillary Longitudinal CSF Collection Study in the Harvard Biomarker Study - HBS2

Parkinson's Disease

The Harvard Biomarker Study is a Harvard-wide, longitudinal case-control study designed for discovering, replicating, and developing biomarkers for Parkinson's disease and Alzheimer's disease. High-quality biosamples and high-resolution clinical phenotypes are tracked at three visits over a two-year period for more than 2,000 individuals with early-stage PD, MCI/AD, and controls without neurologic disease. The present "Ancillary Longitudinal CSF Collection Study (short HBS2)" is an ancillary study to the parent Harvard Biomarker Study. HBS2 is funded by the NINDS. In HBS2, 75 participants are more intensely studied and followed over a three-year time period. Clinical data and blood biospecimens are collected every six months and four annual CSF collections are performed. Biospecimens and clinical data are deposited into the NINDS PD Biomarkers Program (PDBP) Repository and the Data Management Resource (DMR) and are accessible through the PDBP DMR website.

Emotional and Cognitive Subthalamic Nucleus in Deep Brain Stimulation Treated Parkinson Patients...

Parkinson's Disease

About 300 patients with Parkinson's disease (PD) have been successfully treated by deep brain stimulation (DBS) during the last 10 years in Hadassah. In most of the patients the site of stimulation is the subthalamic nucleus (STN). Recent studies by our group and others have demonstrated that the STN is divided into motor and non-motor areas. The investigators have recently shown that electrophysiological mapping of the STN during the surgery can differentiate motor and non-motor areas of the STN. Existing methods of adjustment of DBS parameters aim at amelioration of the motor signs and therefore with inactivation of the STN motor territory only. Although the DBS parameter setting is believed to influence the mental and cognitive states, there is no data that correlates stimulation parameters with mental and cognitive state. In addition, DBS parameter setting is also believed to influence important verbal functions which are partially related to motor, mental and cognitive states, but no data correlates the verbal function with the DBS stimulation parameters. The investigators hypothesize that the cognitive areas of the STN have distinct electrophysiological properties similar to our findings with the limbic / mental areas of the STN. The investigators further hypothesize that specific stimulation of these cognitive areas can influence the cognitive state and thus treatment with cognitive-adjusted DBS can improve the cognitive symptoms of PD. In this project, the investigators intend to map the motor, emotional and cognitive areas of the STN using neuronal (single units) responses to emotional voices and cognitive tasks and to identify the emotional and cognitive spectral signature of the STN single unit activity using spectral analysis and neuronal responses to emotional voices and cognitive tasks. In addition the investigators intend to find the neuronal signature of speech and to find the correlation between motor, mental and limbic electrophysiology to speech. The investigators also intend to investigate the motor, emotional and cognitive processing of PD patients by manipulating the stimulation of the STN. The proposed study will combine neural recording, stimulation and psychological and cognitive tests to shed new light on processing in the basal ganglia, as well as to provide better treatment for PD patients.

Clinical Profile of Parkinson's Disease in Patients With Hepatitis C Infection

Parkinson Disease

There is association between Hepatitis C and Parkinson's Disease as shown from previous studies. The clinical profile and natural history is not fully studied yet. We aim at studying the clinical characteristics of Parkinson's Disease in patients with hepatitis C infection.

Sleep, Awake & Move - Part I

Idiopathic Parkinson Disease

Sleep benefit (SB) is a prominent spontaneous, apparently unpredictable, transitory improvement in motor function reported by around 50% of patients affected by Parkinson's Disease (PD) after sleep and before taking their first dose of dopaminergic medications. This study aims at systematically characterizing SB in PD patients in an ecological setting and to explore the relationships between nocturnal and diurnal sleep and subjective and objective measures of motor function. A better understanding of this phenomenon is mandatory for future research on this topic.
