Official title: The Chinese Parkinson's Disease With GBA Variants Registry

Status Recruiting

Clinical Trial Summary

The purpose of the Chinese Parkinson's disease with GBA variants Registry (CPD-GBAR) is to develop a database of patients of Parkinson's disease with Glucocerebrosidase (GBA) gene variants in mainland China.

Clinical Trial Description

Parkinson's disease (PD) is the second most common disorder among neurodegenerative diseases. GBA gene variants such as L444P can influence the risk of developing PD and these variants have the greatest impact on PD susceptibility among all the PD related gene variants yet discovered. The investigators aim to establish a database of PD with GBA variants and characterize the clinical manifestation of these patients in mainland China.

Method:

1. Peripheral blood from patients has been tested to have GBA gene variants.

2. Clinical manifestation will be measured by scales and neurological tests. Standard scales include: Unified Parkinson's Disease Rating Scale(UPDRS), Hoehn-Yahr stages, Non-Motor Symptoms Scale (NMSS), mini-mental state examination (MMSE), Parkinson disease sleep scales (PDSS), Rapid Eye Movement Sleep Behaviour Disorder Questionnaire(RBDQ-HK), Epworth Sleepiness Scale (ESS), Rome III functional constipation scale, the Scale for Outcomes in PD for Autonomic Symptoms (SCOPA-AUT), Parkinson Fatigue Scale (PFS), Cambridge-Hopkins Restless Legs Syndrome questionnaire (CHRLSq), Hyposmia rating scale(HRS), Hamilton depression scale, the 39-item Parkinson's Disease Questionnaire(PDQ-39), Freezing of gait scale(FOG), dyskinesia related scales, Wearing-off scale(WO).

3. The investigators will also exam the blood biomarkers of PD such as uric acid and peripheral inflammatory markers. ;
