Background Previous studies have demonstrated a higher prevalence of Helicobacter pylori (H. pylori) infection in patients with Parkinson's disease (PD) compared to controls. H. affects levodopa absorption and its eradication significantly improves clinical response levodopa. Here, we studied the effects among our PD patients. Methods A prospective study involving idiopathic on therapy. 13C-urea breath test (UBT) was used detect pylori. UBT-positive were given standard therapy followed up at...

Background . The nonmotor symptoms are important determinants of health and quality life in Parkinson’s disease but not well recognized addressed clinical practice. This study was conducted to determine the prevalence their impact on patients with disease. Methods a cross-sectional among idiopathic Exclusion criteria were Mini Mental State Examination score <21/30. Prevalence determined using NMSQuest. severity assessed validated disease-specific questionnaires (PDQ-39 NMSS). Results A...

Abstract Background Dengue is a common illness in the tropics. Equally are neurological complications that stem from dengue infection. However, to date, parkinsonism following has not been reported medical literature. Case presentation A previously well 18-year old man developed parkinsonism, addition other symptoms serologically confirmed fever. Alternative etiologies were excluded by way of imaging and blood investigations. Conclusions The authors detail first case complicating Keeping...

Chronic pulsatile levodopa therapy for Parkinson's disease (PD) leads to the development of motor fluctuations and dyskinesia. We studied prevalence predictors levodopa-induced dyskinesia among multiethnic Malaysian patients with PD.This is a cross-sectional study involving 95 PD on uninterrupted at least 6 months. The instrument used was UPDRS questionnaires. were determined using multivariate logistic regression analysis.The mean age 65.6 ± 8.5 years. onset 58.5 9.8 median duration (7)...

Several methods of motor tasks for fMRI scanning have been evolving from simple to more complex tasks. Motor on upper extremity were applied in order excite the increscent activation contralesional and ipsilateral hemispheres brain. The main objective this study is different conditions that affected brain activation. Ten healthy right handed with normal vision (3 male 7 female, age range=20-30 years, mean=24.6 SD=2.21) participated study. Prior scanning, participants trained hand grip using...
