Deep brain stimulation in the subthalamic nucleus is an effective and safe surgical procedure that has been shown to reduce the motor dysfunction of patients with advanced Parkinson's disease. Bilateral subthalamic nucleus deep brain stimulation, however, has been associated with declines in cognitive and cognitive-motor functioning. It has been hypothesized that spread of current to nonmotor a...

Wireless deep brain stimulation of well-defined neuronal populations could facilitate the study of intact brain circuits and the treatment of neurological disorders. Here, we demonstrate minimally invasive and remote neural excitation through the activation of the heat-sensitive capsaicin receptor TRPV1 by magnetic nanoparticles. When exposed to alternating magnetic fields, the nanoparticles di...

INTRODUCTION Deep brain stimulation is a stereotactic neurosurgical method used in the treatment of Parkinson's disease and some other movement disorders. The application of deep brain stimulation in the treatment of certain psychiatric disorders has been intensively investigated taking into account the current knowledge of neurobiological basis of mood regulation, cognition, and behaviour. Thi...

Deep brain stimulation (DBS) is a new neurosurgical method principally used for the treatment of Parkinson disease (PD). Many new applications of DBS are under development, including the treatment of intractable psychiatric diseases. Brain imaging is used for the selection of patients for DBS, to localize the target nucleus, to detect complications, and to evaluate the final electrode contact p...

The few controlled studies that have been carried out have shown that bilateral internal globus pallidum stimulation is a safe and long-term effective treatment for hyperkinetic disorders. However, most recent published data on deep brain stimulation (DBS) for dystonia, applied to different targets and patients, are still mainly from uncontrolled case reports (especially for secondary dystonia)...

Obesity is now the third leading cause of preventable death in the US, accounting for 216,000 deaths annually and nearly 100 billion dollars in health care costs. Despite advancements in bariatric surgery, substantial weight regain and recurrence of the associated metabolic syndrome still occurs in almost 20-35% of patients over the long-term, necessitating the development of novel therapies. O...

Dopaminergic treatments are associated with impulse control disorders such as pathological gambling in a subset of patients with Parkinson's Disease. While deep brain stimulation of the subthalamic nucleus has been reported to reduce symptoms of impulse control disorders in some Parkinson's Disease patients, little is known about its specific effects on gambling behaviour. In this experiment, w...

Chronic high frequency stimulation of the subthalamic nucleus (STN) of the basal ganglia is a highly effective treatment for Parkinson’s Disease (PD). Such deep brain stimulation is thought to suppress spontaneous, including pathological, activity in the basal ganglia [1–5]. Equally, however, it must also remove any residual physiological functioning in these key motor structures, and yet there...

CONTEXT Deep brain stimulation is an accepted treatment for advanced Parkinson disease (PD), although there are few randomized trials comparing treatments, and most studies exclude older patients. OBJECTIVE To compare 6-month outcomes for patients with PD who received deep brain stimulation or best medical therapy. DESIGN, SETTING, AND PATIENTS Randomized controlled trial of patients who re...
