چکیده

OBJECTIVE Subthalamic nucleus-deep brain stimulation (STN-DBS) is an alternative treatment for patients with uncontrolled symptoms of Parkinson's disease (PD), but it has other nonmotor impact. Because STN-DBS alters the energy expenditure in humans, we hypothesized that STN-DBS may affect postabsorptive glucose metabolism in patients with PD. RESEARCH DESIGN AND METHODS Endogenous glucose production (EGP) and whole-body glucose disposal rates (GDRs) were assessed in the postabsorptive state during a primed continuous iv infusion of D-[6,6-(2)H2]glucose for 5 hours in 8 STN-DBS-treated patients with PD, without (Stim-OFF) and during STN-DBS (Stim-ON) treatment. EGP and GDR in PD patients were compared with glucose kinetics of 8 matched healthy control subjects. Plasma concentrations of insulin, glucagon, and free fatty acids were also determined. RESULTS EGP and GDR were higher in PD patients in Stim-OFF conditions than in the control group (2.62 ± 0.09 vs 2.27 ± 0.10 mg/kg·min, P < .05). Despite no significant changes in blood glucose throughout the kinetic study, a significant and consistent 22% decrease in EGP occurred in PD patients during Stim-ON (2.04 ± 0.07 mg/kg(-1)·min(-1); P < .01), and whole-body glucose kinetics in Stim-ON patients were no more different from those of the control subjects (P = NS). No difference in insulin, glucagon, or free fatty acid concentrations was observed in the patients between Stim-OFF and Stim-ON conditions. CONCLUSIONS Deep brain stimulation in patients with PD affects EGP glucose disposal, suggesting that a cross talk between the central nervous system and peripheral tissues may regulate glucose homeostasis.

  Abstract   Introduction: It is demonstrated that the degree of clinical improvement in   Parkinson's disease (PD) achieved by deep brain stimulation (DBS) is largely dependent   on the accuracy of lead placement. In addition, individual variability in the   situation of subthalamic nucleus (STN) is responsible for spatial inter-individual   fluctuations of the real patient's target.   Objecti...

Background: The effect of subthalamic nucleus deep brain stimulation (STN-DBS) on the voice features in Parkinson&rsquo;s disease (PD) is controversial. No study has evaluated the voice features of PD underwent STN-DBS by the acoustic, perceptual, and patient-based assessments comprehensively. Furthermore, there is no study to investigate prosodic features before and after DBS in PD. The curren...

Subthalamic nucleus stimulation does not influence basal glucose metabolism or insulin sensitivity in patients with Parkinson's disease

Animal studies have shown that central dopamine signaling influences glucose metabolism. As a first step to show this association in an experimental setting in humans, we studied whether deep brain stimulation (DBS) of the subthalamic nucleus (STN), which modulates the basal ganglia circuitry, alters basal endogenous glucose production (EGP) or insulin sensitivity in patients with Parkinson's d...
