title: Bone mineral density in patients with Parkinson's Disease.
abstract: OBJECTIVE
  This study assesses bone mineral density (BMD) in the lumbar spine, proximal femur and hand, and examines the relationship between BMD and disease duration, Hoehn and Yahr staging in Turkish elderly patients with Parkinson's disease (PD).
  
  
  METHODS
  Twenty-four PD patients and 31 age- and sex-matched controls took part in the study. The BMD in the lumbar spine (L2-L4), femoral neck, Ward's triangle, trochanter and bilateral hands were evaluated by dual X-ray absorptiometry (DXA).
  
  
  RESULTS
  There was no significant difference in right hand BMD (rHBMD), L2-L4 spinal BMD, and right proximal femur BMD between patients and controls. However, in female patients hand BMD and right femoral neck BMD were significantly lower than in female controls (p<0.05). Male patients had no significant difference in BMD measurements in any sites compared with controls. Patients' Hoehn and Yahr index and disease duration were negatively correlated with BMD in all sites except L2-L4.
  
  
  CONCLUSIONS
  We emphasize the increased risk for osteoporosis in elderly female patients with PD, which is more prominent in proximal femur and hand measurements. Elderly female patients should be carefully examined and screened for osteoporosis to prevent bone loss and associated disability.
