Introduction: Idiopathic Parkinson's disease is a neurodegenerative disorder characterized by motor disorders, akinesia or bradykinesia, rigidity, resting tremor and impaired posture reflexes or even frequent falls. In daily practice, an abnormal blood pressure profile is often observed in parkinsonian patients. In this study, we described the 24h blood pressure profile in our patients with idiopathic Parkinson's disease. Methodology: This is a prospective and descriptive observational study of patients hospitalized from May to October 2016 for idiopathic Parkinson's disease at the Department of Neurology at Pontarlier Hospital. We included all patients with an UPDRS (Unified Parkinson's Disease Rating Scale) score greater than 12 who made a consciousness (20%), isolated falls (12%), vertigo (11%), visual blur (8%), and other signs (25%). Conclusion: The particular clinical manifestations related to hypotension deserve more attention from us based on the interest of a systematic research in all the parkinsonian and related patients.
