Eligibility Criteria: Inclusion Criteria: * Patients diagnosed with PD or VP, and healthy controls will be included in the study. * PD diagnosis will be based on the Queen Square Brain Bank for Neurological Disorders clinical criteria and MDS criteria. * The VP patients will be included if they fulfill the following criteria (Zijlman's diagnostic criteria)Parkinsonism presentation (at least two of the cardinal features: tremors, bradykinesia, rigidity and postural instability). Cerebrovascular disease, defined as evidence of relevant cerebrovascular disease by brain imaging or the presence of focal signs or symptoms consistent with stroke. A relationship between (1) and (2): acute or delayed progressive onset of parkinsonism. Based on the above criteria, two forms of VP are suggested: one with acute onset, and another one with insidious progression. The diagnosis will be confirmed by assigning a vascular score. Two points or more are essential to diagnose VP. The points will be assigned as follows: * Two points: Pathologically or angiographically proven diffuse vascular disease. * One point: Onset of parkinsonism within 1 month of clinical stroke. * One point: History of two or more strokes. * One point: Neuroimaging evidence of vascular disease in two or more vascular territories. * One point: History of two or more risk factors for stroke (hypertension, smoking, diabetes mellitus, hyperlipidaemia, presence of heart disease associated with stroke \[coronary artery disease, atrial fibrillation, congestive heart failure, valvular heart disease, mitral valve prolapse, and other arrhythmias\], family history of stroke, history of gout, and peripheral vascular disease) Exclusion Criteria: * PD patients with age at onset less than 40 years. * Any alternative cause that significantly impair gait. * Inability of the patient to undergo neuroimaging. * Patients couldn't perform the test or severely demented. * Atypical and other secondary parkinsonism as patients who had a history of toxin exposure.or antipsychotic drugs treatment by history ,neurological examination and brain MRI . * Family or patient's refusal to give written consent.
