We have recently found that cannabinoid receptor binding and gene expression markedly decreased in extrapyramidal structures of aged rats. The present study was designed to analyze the possible existence of similar aging-induced changes in cannabinoid receptor binding and gene expression in brain regions other than extrapyramidal areas, but that also(More)
One potential complication of treating Parkinson's Disease (PD) with dopaminergic drugs is dopamine dysregulation syndrome, an addiction-like response to the drug therapy. Here, we assessed whether rats given parkinsonian-like symptoms with a unilateral injection of 6-hydroxydopamine into the medial forebrain bundle (6-OHDA-MFB), exhibit similar behavior.(More)
BACKGROUND At least 14% of Parkinson disease (PD) patients develop impulse control disorders (ICDs). The pathophysiology behind these behaviors and the impact of deep brain stimulation in a real-life setting remain unclear. OBJECTIVES We prospectively examined the impact of bilateral subthalamic nucleus deep brain stimulation (STN-DBS) on ICDs in PD(More)
INTRODUCTION As many as 30% of spinal cord stimulation (SCS) patients fail to obtain long-term pain coverage, even with the strictest parameters of a successful trial, unremarkable psychological assessment, and ideal placement of the permanent device. Why these patients either never receive adequate benefit or lose benefit remains elusive. METHODS We(More)
BACKGROUND Peripheral nerve stimulation (PNS) of the named nerves of the head has been shown to be effective in reducing pain levels in patients with chronic pain refractory to other treatments. However, the impact of cranial PNS on depression and disability has not been well documented. OBJECTIVES We prospectively examine the impact of PNS on quality of(More)
BACKGROUND Accurate lead placement is critical for spinal cord stimulation (SCS) efficacy. The traditional gold standard of awake placement is often technically difficult. While there is retrospective evidence supporting the use of intraoperative neurophysiological monitoring (IOM) as an alternative, a prospective assessment has not yet been performed. (More)
BACKGROUND Occipital nerve stimulation (ONS) is a therapy that benefits one-third of medically refractory chronic migraine (CM) patients. How ONS affects sensory thresholds and whether modulation of thresholds could predict which patients respond to the therapy remains unclear. OBJECTIVE To examine the effects of ONS on mechanical and thermal thresholds(More)
