Tiempo desde el inicio de los síntomas motores hasta el diagnóstico de enfermedad de parkinson (Ep) en méxico

Introduction: Parkinson’s disease is characterized by a wide spectrum of motor and non-motor symptoms with an insidious onset. Identification of these symptoms by the patient as well as by the physician is determinant in order to achieve an early diagnosis. Objective: To determine the time from motor symptoms onset to the diagnosis of Parkinson’s disease and analyze the clinical and demographic factors related to it. Material and methods: A cross-sectional study was carried out including subjects with Parkinson’s disease seen during the 2011-2012 period and belonging to the Mexican National Parkinson’s Registry. Time from symptom onset to the diagnosis was collected; its relation with demographic and clinical characteristics was assessed. Results: A total of 1,062 subjects were included. Delay in diagnosis was 29.5 months. Predictive factors for a longer diagnostic delay were symptoms onset before 40 years of age (B: –0.350; p < 0.001) and a positive family history of Parkinson’s disease (B: 0.224; p < 0.001). Conclusions: The diagnosis of Parkinson´s disease in Mexico is two and a half times greater than what has been reported for other countries.
