简要总结
Young Onset Parkinson's disease (YOPD) refers to a group of patients in which the disease starts earlier in life (before the age of 50 years) and has a profound impact on most of patient's life. Current knowledge regarding the mechanisms leading to development of Parkinson's disease in younger individuals is lacking, but their understanding is crucial for the successful design of therapeutic strategies and stratifying patients for clinical trials. With this research the investigators aim to clarify the contribution of relevant biological processes in patients with Young onset Parkinson's disease to help understanding disease mechanisms and biomarkers.
详细描述
With the present project the investigators propose to study clinical and biological data (from peripheral blood and skin punch biopsy) in subjects with Young and Late Onset Parkinson's disease as well as non-affected subjects (controls) to identify characteristic biological traits for each for this groups.
For each participant, the investigators will collect information about demographic data, clinical data related to the symptoms of Parkinson's disease through standard questionnaire, a clinical exam, and standard interview. A blood sample (from a peripheral vein) and skin punch biopsy will be collected to study genetic and biological markers of the disease. The study duration for each participant is of one in-person visit at the study center.
In a subgroup of subjects, biological data from the lumbar puncture will be collected and analyzed as well.
