Filter by:- To determine whether retinal abnormalities, as measured by high definition optical coherence tomography (HD-OCT) and visual electrophysiology techniques can be used as a clinical biomarker to monitor disease progression overtime in patients with Parkinson disease. - To establish whether these measures can be used to identify patients with PD in the premotor phase. - To define the rate of progression of retinal abnormalities in PD (both in the motor and premotor stages) for potential use as a clinical outcome measure
Based on previous promising results, the next step for the validation of a multimodal MRI method in diagnosis and follow up of patients reached by parkinsonian syndromes is (i) to test whether the multimodal neuroimaging is able to discriminate at the individual level, patients with multiple system atrophy parkinsonism (MSA) and patients with idiopathic Parkinson's disease (PD) (ii) to determine whether the method is sensitive to measure changes over time for the two diseases, according to imaging, neuropsychological and other clinical data. Patients will be compared with healthy controls.
Patients with autonomic failure are characterized by disabling orthostatic hypotension (low blood pressure on standing), and at least half of them also have high blood pressure while lying down (supine hypertension). Exposure to heat, such as in hot environments, often worsens their orthostatic hypotension. The causes of this are not fully understood. The purpose of this study is to evaluate whether applying local heat over the abdomen of patients with autonomic failure and supine hypertension would decrease their high blood pressure while lying down. This will help us better understand the mechanisms underlying this phenomenon, and may be of use in the treatment of supine hypertension.
AZD3241 myeloperoxidase (MPO) inhibitor trial is assessing safety and tolerability, randomized trial, in patients with Multiple System Atrophy.
This is a randomized controlled parallel Group phase I study to investigate the safety and immunological/ therapeutic activity of two new vaccines, AFFITOPE® PD01A and AFFITOPE® PD03A, given to patients with early Multiple System Atrophy (MSA). In total 30 patients are planned to be enrolled in the study: 12 patients in each treatment arm who will receive either 75µg AFFITOPE® PD01A (with adjuvant) or 75µg AFFITOPE® PD03A (with adjuvant) and 6 patients in the control group who will receive the reference substance (Placebo). Over a study duration of 52 weeks, the study participants will receive 4 injections as basic immunization in a 4-weekly interval and 1 boost immunization 36 weeks after the first injection. Male and female patients aged 30 to 75 years can participate in the trial. 2 study sites in France (Bordeaux and Toulouse) will be involved. AFF009 is part of the project SYMPATH funded by the European Commission (FP7-HEALTH-2013-INNOVATION-1 project; N° HEALTH-F4-2013-602999).
The PET tracer [F18]-FDDNP has a specific affinity for lesions containing tau protein. The study consists of two phases: - In the first (cross-sectional) phase it will be assessed the uptake of [18F]-FDDNP in 10 cases with progressive supranuclear palsy (PSP, a tauopathy) en 10 with multi-system atrophy (MSA, a non-tauopathy), along with 20 individuals with Unclassifiable Parkinsonism, as previously defined in a European cohort study. - In the second (longitudinal) phase it will be prospectively followed the 20 unclassifiable patients (at 6, 12 and 18 months) by means of validated scales and accepted diagnostic criteria in order to try to correlate their eventual clinical diagnosis with baseline PET findings. On this basis, we endeavour to estimate the ability of this technique to detect in vivo underlying tau pathology in subjects initially unclassifiable on clinical grounds. We hypothesized that: 1. Patients with clinically definite PSP will present an increased uptake in basal ganglia, brainstem and cerebellum. 2. Patients with clinically defined MSA will not present specific uptake. 3. Part of unclassifiable patients with parkinsonism will present a pattern of uptake similar to patients with clinically defined PSP and this part along the clinical follow-up will be meet clinical criteria for diagnose of PSP
The main objective of the study is to compare the score to the Behavioral Dysexecutive Syndrome Inventory (BDSI) between Parkinsonian Multiple system Atrophy MSA-P patients and cerebellar Multiple System Atrophy (MSA-C) patients matched on disease duration, age (± 7 years) and sex .
Investigators hypothesize that there are specific characteristic of each cognitive and motor condition that can be defined using brains scans.
Evaluate the effects of L-Threo DOPS on orthostatic hypotension symptoms and other non-motor symptoms in patients with Multiple System Atrophy (MSA) after 12 weeks following randomization to continued therapy with droxidopa or placebo.
Parkinson disease (PD) and multiple system atrophy (MSA) are progressive neurodegenerative disorders characterized by abnormal accumulation of α-synuclein. There is no effective treatment that can slow down the disease progression and both disorders are associated with severe cognitive decline. It was shown that intranasal insulin (INI) improves learning and memory in healthy and cognitively impaired non-diabetic adults. The proof-of-concept, randomized, placebo-controlled, cross-over pilot study ( NCT01206322) has shown that a single 40 international units dose of intranasal insulin improves visuospatial memory in diabetes and control subjects. This proposal includes randomized, double blinded, placebo-controlled trial of intranasal insulin (40 international units daily) in treatment of PD and MSA. The study will evaluate 22 patients with PD and 22 patients with MSA. Total duration of the study will be 2 years. The primary goal is to assess the efficacy of INI in treatment of cognitive abnormalities in both PD and MSA. The primary efficacy end point will be change of the cognitive scale ratings.
