Brief Summary: This study will identify abnormalities of a protein called alpha synuclein that is found in the brain of patients with Parkinsons disease and related disorders to see if it can serve as a disease marker There is currently no treatment that will cure or delay progression of Parkinsons disease Thus there is a need to find disease markers that can help diagnosis the disease follow its progression and monitor the effects of treatment This study will examine and compare alpha synuclein from blood and cerebrospinal fluid the fluid that bathes the brain and spinal cord of patients with Parkinsons disease patients with variants of the disease and healthy normal volunteers to determine differences in the protein that might serve as a disease marker

Patients with neurodegenerative disorders such as Parkinsons disease and Parkinson plus disorders other diseases that are variants of Parkinsons disease and healthy volunteers between 18 and 80 years of age may be eligible for this study Candidates are screened with a medical history physical examination neurological evaluation and blood tests A brain MRI magnetic resonance imaging scan is done if needed for diagnosis

All participants have a blood sample drawn and a lumbar puncture spinal tap For the lumbar puncture a local anesthetic is given and a needle is inserted in the space between the bones in the lower back where the cerebrospinal fluid circulates below the spinal cord A small amount of fluid is collected through the needle The fluid is analyzed for specific proteins and chemicals that are leaked from the brain in various disease states and that cannot be measured in blood

Participation of healthy volunteers is completed after the blood draw and lumbar puncture Patients with Parkinsons and related diseases return to the clinic once a year for 2 years for a repeat blood draw and lumbar puncture to follow changes in the alpha synuclein protein and to monitor disease progression Patients with specific proteins of interest may also be asked to come for a repeat lumbar puncture 6 months after the first procedure
Detailed Description: OBJECTIVE Parkinsons disease PD is a progressive neurodegenerative disorder of unknown etiology in which several underlying pathophysiological mechanisms including proteasomal degradation mitochondrial dysfunction inflammation oxidative stress and excitotoxicity may contribute to cell death No treatment is known to cure or delay progression of PD thus there is a need to investigate measurable biologic markers for the purpose of diagnosis monitoring disease progression and effect of treatment This study will focus on alpha synuclein and its metabolic pathways as a potential biomarker to assist in evaluation of pathogenesis and future diagnostic and therapeutic options

STUDY POPULATION In this pilot study we plan to include 30 patients with Parkinsons disease PD 30 patients with Parkinson plus disorders and 30 control patients without neurologic disease or autoimmune disorders

DESIGN Samples of serum plasma and cerebrospinal fluid CSF will be collected from all patients for analysis at the beginning of the study The assay will be performed for various proteins including cytokines primarily related to the alpha synuclein AS pathway A repeat CSF plasma and serum analysis will be performed in patients with PD and Parkinson plus disorders at the end of one and two years to follow changes of protein expression profiles with disease progression

ASSESSMENT OF RISKS AND BENEFITS This study will carry the risk associated with venepuncture and lumbar puncture

OUTCOME ESTIMATE AND POTENTIAL MEANING FOR THE FIELD The primary outcome measure is to correlate the changes of alpha synuclein phosphorylation in CSF plasma and serum with changes in UPDRS motor score in patients with PD over the period of 2 years compared to controls The secondary aim of the study is to compare the protein expression profiles between different synucleinopathies including PD Multiple System Atrophy MSA and Dementia with Lewy Bodies DLB with time There are currently no validated surrogate disease markers in PD or other related neurodegenerative disorders Our work would hopefully help understand pathophysiologic mechanisms in patients with PD monitor disease progression using specific biologic markers and in future development of targeted therapies
