Estimates of the spectrum and frequency pathogenic variants in Parkinson's disease (PD) different populations are currently limited biased. Furthermore, although therapeutic modification several genetic targets has reached clinical trial stage, a major obstacle conducting these trials is that PD patients largely unaware their status and, therefore, cannot be recruited. Expanding number investigated PD-related genes including related to disorders with overlapping features large,...

Background. Novel rehabilitation strategies have demonstrated potential benefits for motor and non-motor symptoms of Parkinson's disease (PD). Objective. To compare the effects Lee Silverman Voice Therapy BIG (LSVT therapy) versus a general exercise program (combined treadmill plus seated trunk limb exercises) on PD. Methods. Eleven patients with early-mid stage PD participated in prospective, double-blinded, randomized clinical trial. Both groups received 16 one-hour supervised training...

RimabotulinumtoxinB (RIMA) may be preferable as an anti-sialorrhea treatment compared with current oral anticholinergic drugs in people neurological disorders.To assess the safety, efficacy, and tolerability of RIMA injections for sialorrhea adults.This randomized, parallel, double-blind, placebo-controlled clinical trial 2500 U 3500 was conducted from November 14, 2013, to January 23, 2017. A total 249 adult patients troublesome secondary any disorder or cause were screened. Of them, 13...

Cognitive impairment is a common nonmotor symptom among individuals with Parkinson's disease (PD). Although cognitive generally develops progressively, PD-associated mild (PD-MCI) may revert to being cognitively normal (CN), which referred as PD-MCI reversion. Previous studies are inconsistent in whether reverters at greater risk for recurrence relative CN individuals. Even less known about how compare or nonreverters terms of neurodegenerative biomarkers. The authors examined group...

Background Continuous subcutaneous apomorphine infusion (CSAI) has been used globally since the 1980s for Parkinson disease (PD) motor fluctuations but not available in United States (US). Objective Evaluate CSAI US setting. Methods This open-label study (NCT02339064) enrolled patients with PD experiencing ≥3 hours (h) daily OFF time despite optimized levodopa and current/prior use of at least one other adjunctive therapy. was initiated a 1–2 mg bolus followed by 1 mg/h titrated to optimal...

Abstract Active caspase‐3 immunoreactivity was detected in the rat forebrain proliferative regions at birth and remained high these areas for about 2 weeks, during which period labeled cells were present centroperipherally across olfactory bulb. By end of third postnatal week, only a small number immunolabeled structures. immunolabeling localized mostly to cell nuclei co‐localized partially with TuJ1 NeuN immunoreactivity, but not glial fibrially acidic protein, OX‐42, γ‐aminobutyric acid,...

Background. Iron is considered to lead neurodegeneration and has been hypothesized as a possible cause of Parkinson's disease (PD). Susceptibility-weighted imaging (SWI) powerful tool measure phase related iron content brain. Methods. Twelve de novo patients with PD were recruited from the Movement Disorders Clinic, Department Neurology, Loma Linda University. age- sex-matched non-PD subjects neurology clinic controls. Using SWI, was estimated different brain regions interest (ROIs)....
