Deep Brain Stimulation News and Research RSS Feed - Deep Brain Stimulation News and Research

Deep brain stimulation (DBS) is a surgical procedure used to treat a variety of disabling neurological symptoms—most commonly the debilitating symptoms of Parkinson’s disease (PD), such as tremor, rigidity, stiffness, slowed movement, and walking problems. The procedure is also used to treat essential tremor, a common neurological movement disorder. At present, the procedure is used only for patients whose symptoms cannot be adequately controlled with medications.

DBS uses a surgically implanted, battery-operated medical device called a neurostimulator—similar to a heart pacemaker and approximately the size of a stopwatch—to deliver electrical stimulation to targeted areas in the brain that control movement, blocking the abnormal nerve signals that cause tremor and PD symptoms.

Before the procedure, a neurosurgeon uses magnetic resonance imaging (MRI) or computed tomography (CT) scanning to identify and locate the exact target within the brain where electrical nerve signals generate the PD symptoms. Some surgeons may use microelectrode recording—which involves a small wire that monitors the activity of nerve cells in the target area—to more specifically identify the precise brain target that will be stimulated. Generally, these targets are the thalamus, subthalamic nucleus, and globus pallidus.

GW clinical trial aims to identify novel modalities to reduce seizures in MTLE patients

A first-of-its-kind clinical trial at the George Washington University Medical Faculty Associates employs low-frequency deep brain stimulation to potentially help reduce epileptic seizures in patients with mesial temporal lobe epilepsy (MTLE) - the most common type of focal epilepsy that often necessitates surgical resection of the temporal lobe, risking memory function.

Study results suggest growing support for patient-centered care management

Primary care doctors practicing in a model of coordinated, team-based care that leverages health information technology are more likely to give patients recommended preventive screening and appropriate tests than physicians working in other settings, according to research published today in the Annals of Internal Medicine.

Neural engineers to develop techniques for dynamic deep brain stimulation

Neural engineers to develop techniques for dynamic deep brain stimulation

Deep brain stimulators, devices that zap Parkinson's disease tremors by sending electrical current deep into nerve centers near the brain stem, may sound like they are cutting-edge, but Rice University's Caleb Kemere wants to give them a high-tech overhaul. [More]
New optical approach to brain scanning for patients with electronic implants

New optical approach to brain scanning for patients with electronic implants

Scientists have advanced a brain-scanning technology that tracks what the brain is doing by shining dozens of tiny LED lights on the head. This new generation of neuroimaging compares favorably to other approaches but avoids the radiation exposure and bulky magnets the others require, according to new research at Washington University School of Medicine in St. Louis.

Researchers devise new approach to treatment of Alzheimer's disease

A team of researchers from Columbia University Medical Center, Weill Cornell Medical College, and Brandeis University has devised a wholly new approach to the treatment of Alzheimer's disease involving the so-called retromer protein complex. Retromer plays a vital role in neurons, steering amyloid precursor protein (APP) away from a region of the cell where APP is cleaved, creating the potentially toxic byproduct amyloid-beta, which is thought to contribute to the development of Alzheimer's.

Viewpoints: Obama's budget punts on entitlements; Medicaid debate rankles states

Viewpoints: Obama's budget punts on entitlements; Medicaid debate rankles states

There is a lesson in this unexpected juxtaposition nevertheless: No nation can safely base its tax and spending plans on inflexible commitments. Political life, both domestic and international, is too unpredictable. Yet U.S. government spending is mostly on autopilot. The government is scheduled to lay out $3.8 trillion this fiscal year -; 70 percent of which will go to mandatory-spending programs, chiefly Social Security, Medicare, Medicaid and interest on the federal debt. Mr. Obama's plan for fiscal 2015 does not change this; it would increase overall spending slightly, paying for it with selected tax increases, while shifting money among priorities here and there. But these tweaks would take place within the same 30 percent of discretionary spending that the current budget contains (3/4). [More]
