Filter by:Gait disturbances are very common and are a major cause for losing of independency in patients with advanced Parkinson's Disease (PD). The medical treatment of gait disturbances in advanced PD is very difficult and in many cases the classical dopaminergic treatment has no clinical benefit or even can worsen the instability and increase falls. Rasagiline, a new MAO-B inhibitor who has recently been approved all over the world for the treatment of early and late stages PD has been suggested to have a special effect of gait in patients with advanced PD (LARGO sub-study).
The present study is part of an international program and deals with the translation and validation program for the Italian version of the MDS-UPDRS. The program will be articulated in three steps: - Phase I: translation and back-translation of the MDS-UPDRS in Italian (completed) - Phase II: Cognitive testing. This step is aimed at a preliminary testing of a subset of potentially culturally sensitive items in a limited set of PD patients (approximately 10). Should this phase identify issues in the understanding and ease of use of some items a revised translation of some individual items might be envisaged. - Phase III: large validation testing: this phase will involve 350 PD patients from 12-14 Italian PD centres. The IRIS protocol deals with phase II and III of the program.
Parkinson disease is one of the most common neurodegenerative illnesses. The disease is characterized by decrease in dopamine levels and decrease in the number of dopaminergic neurons and dopamine receptors. There are gene mutations that increase the risk for the disease. Two of those mutations are on the LRRK2 gene and on GBA gene. It is yet unknown if there is a difference between the metabolic brain function of Parkinson patients that carry one of the two mutations to Parkinson patients with no known mutation. Participants: diagnosed Parkinson patients that carry a gene mutation in either LRRK2 or GBA genes, Parkinson patients with no known mutation and healthy volunteers as a control group. The participants will go through both examinations DAT SCAN and PET CT SCAN at the Tel Aviv Sourasky Medical Center Nuclear Medicine Institute. The examination results will be given to the participants by a doctor from the neurology department.
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.
The relationship between WM lesions (WM) and Postural Instability Gait Disorders (PIGD-PD)in Parkinson's disease patients is largely unknown. We hypothesize that sub-clinical WM pathology may be a major contributing factor to PIGD-PD. We will compare two groups of patients with Parkinson's disease (PD): those with PIGD and patients with dominant tremor (n=120)to assess the role of brain WM changes.
The aim of this study is to analyze the effects of two different targets of deep brain stimulation: caudal Zona incerta and Nucleus subthalamicus. The present study will investigate the effects of DBS using a blind, randomized and stratified design in patients with Parkinson's disease.
The purpose of this study is to characterize and compare irregularities in dopaminergic function in fronto-subcortical circuits, between Parkinson's Disease patients (ON and OFF medication) and patients with obsessive-compulsive disorder, by examining performance on cognitive tasks involving cognitive flexibility, decision-making, and attentional bias.
There's high incidence of seborrhic dermatitis among patients suffering from Parkinson's disease. Seborrhic dermatitis is caused by increased exertion of sebaceous glands. Previous studies have shown an increase of sebum excretion rate in parkinsonian pateints. Other studies demonstrated improvement in seborrhic dermatitis after anticholinergic treatment. From these studies we concluded that there might be hyperactivity of the parasympathetic system among PD patients, that cause increased exertion of sebum, therefore local injection of botulinium toxin, which inhibitis acetyl choline realese, might improve the rash of seborrhic dermatitis. 40 patients suffering from Parkinson disease or other parkinsonian disorders will participate in this study. Before treating the patients with botulinium toxin, we will measure the sebum exertion with the sebumeter device and make clinical evaluation of the rash. We will also take a picture of the rash. Then Botulinium toxin (60- 100 units) will be locally injected to the rash area. Two weeks after the injection the patients will be called and evaluated clinicly and by the sebumeter. Then they will be checked again after 3 weeks, after a month and after two, three and four month's.
The purpose of this study is to determine whether Fipamezole is effective in the treatment of orthostatic hypotension and related symptoms in multiple system atrophy and Parkinson's disease.
The investigators hypothesize that mathematical algorithm can identify freezing episodes based on data obtained from accelerometer.
