Filter by:This study is designed to learn more about overall tau burden in the brain of patients with Progressive Supranuclear Palsy (PSP).
We are trying to identify factors associated with improved quality of life and fewer PD symptoms. We are attempting to identify practices, beliefs, and therapies used by individuals who report excellent quality of life, few PD symptoms, and reduced rates of progression. After agreeing to participate, we will ask participants to fill our questionnaires about their experience with PD, their health in general, along with their food intake every six months for five years.
Parkinson disease (PD), multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) are neurodegenerative disorders. PD and MSA are alpha-synucleinopathies, which are characterized by the abnormal accumulation of alpha-synuclein, while tau protein accumulates in PSP. The development of biological markers for the diagnosis and prognosis in PD, MSA and PSP remains an unmet need. Such biological markers are crucial for future disease-modification and neuroprotection trials. Alpha-synuclein has a high potential for biomarker development since it constitutes the pathological hallmark feature in PD and MSA. The oligomeric alpha-synuclein seems to be particularly involved in abnormal protein aggregation in alpha-synucleinopathies. The main objective is to compare oligomeric alpha-synuclein CSF levels between PD, MSA and PSP patients. PD and MSA patients will receive Cerebrospinal Fluid (CSF) and blood sampling at two study visits (baseline and after 12 months). Major secondary objectives are (i) to assess potential associations between the biomarker and clinical measures of disease severity and progression in MSA and PSP, and (ii) to assess the variation of the biomarker and its correlation to disease severity and progression in PD, MSA and PSP.
There is evidence suggesting that stem cells harvested from the bone marrow and transplanted into the brain may be effective in slowing down the progression of parkinsonism. Mesenchymal stem cells are able to produce growth factors that provide support to diseased nervous cells. In this study mesenchymal stem cells will be harvested from the bone marrow, cultivated in a test tube so that they multiply and then infused into the arteries that supply blood to the brain in 20 patients suffering from a rare form of parkinsonism, Progressive Supranuclear Palsy. Each patient will undergo two infusions, one with the stem cells and one without, at an interval of 6 months. The sequence of the two infusions will be assigned randomly; patients and assessors will not know the sequence (double-blind). Patients will be followed-up for up to 1 year after the last infusion, with regular assessments to assess safety, efficacy on motor and cognitive functions, and effects on the brain by neuroimaging techniques. The study has a preliminary phase with 5 patients all given stem cell therapy alone, designed to assess safety
to show that 1. patients improve and stabilize after 12 -24 week treatment with rivastigmine in memory function 2. use of rivastigmine has a positive effect on apathy in PSP patients 3. therapy with rivastigmine has a no positive benefit on speech and overall results of the MMST 4. changes in motor activity are associated with changes in language and overall results of the in MMST
The syndrome of distractibility is a behavioral disorder induced by a lesion or a dysfunction of the frontal lobe. This sign is frequent in patients with progressive supranuclear palsy (PSP), a neurodegenerative disorder with severe neuronal loss in the prefrontal cortex and cholinergic systems, in particular in the Meynert basalis nucleus. This could participate in the occurrence of the distractibility in these patients. The aim of this study is to evaluate the effect of the donepezil, an anticholinesterase, on the distractibility in PSP patients, by using oculomotor and neuropsychological assessments.
