Osteoporosis in Parkinson's Disease: Relevance of Distal Radius Dual-Energy X-Ray Absorptiometry (DXA) and Sarcopenia.

Osteoporotic fractures are common in Parkinson's disease (PD). Standard dual-energy X-ray absorptiometry (DXA) measuring bone mineral density (BMD) at the femoral neck and lumbar spine (central sites) has suboptimal sensitivity in predicting fracture risk in the general population. An association between sarcopenia and osteoporosis in PD has not been studied.

Progressive and accelerated weight and body fat loss in Parkinson's disease: A three-year prospective longitudinal study.

Introduction: Although weight loss is common in Parkinson's disease (PD), longitudinal studies assessing weight and body composition changes are limited.

Methods: In this three-year longitudinal study, 125 subjects (77 PD patients and 48 spousal/sibling controls) underwent clinical, biochemical and body composition assessments using dual-energy X-ray absorptiometry.

Results: Patients were older than controls (65.

Understanding patients' and caregivers' perspectives and educational needs in Parkinson's disease: a multi-ethnic Asian study.

Introduction: Little is known regarding the educational needs and perspectives of people living with Parkinson's disease (PD), particularly in Asia.

Objective: To assess knowledge and perceptions regarding PD in a large multiethnic urban Asian cohort of patients and caregivers.

Methods: We conducted a survey at a university hospital neurology clinic, using a novel Knowledge and Perception of Parkinson's Disease Questionnaire (KPPDQ).

Do the dynamic stress mobility radiographs predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty for osteoporotic thoracolumbar vertebral fractures with intravertebral cleft?

Background: This prospective clinical-radiological study was conducted to determine whether the dynamic mobility stress radiographs can predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty.

Methods: Patients included had the diagnosis of significant back pain caused by osteoporotic vertebral compression fracture secondary to trivial injury. All the patients underwent routine preoperative sitting lateral spine radiograph, supine stress lateral spine radiograph, and supine anteroposterior spine radiograph.
