Study Examines Globus Pallidus Internus Stimulation for Medically Refractory Tourette Syndrome

April 13, 2015 - Researchers in the U.K. report that bilateral globus pallidus internus stimulation for severe, medically refractory Tourette syndrome showed a "significant improvement in tic severity, with an overall acceptable safety profile" in a double-blind, randomized crossover trial of 15 patients who were at least 20 years old. The patients received three months each of active or sham stimulation in random order in the crossover trial, and were offered and continued to have open-label stimulation afterward for one month or more. The authors conclude that future research should help identify the most effective brain stimulation target to control both tics and associated comorbidities, as well as delineate factors that predict individual patient response.

Research Indicates Deep Brain Stimulation Facilitates Shifts in Neural Signaling

April 16, 2015 - Researchers who recently published their work in Nature Neuroscience showing a de-coupling of brain oscillations involving the motor cortex during deep brain stimulation in Parkinson's disease patients had supposed stimulation would decrease the strength of beta waves (3 - 30 Hz), but instead found that there was less synchrony between those oscillations and the amplitude of broadband activity in the brain (50 - 200 Hz), an article in medwireNews explains. In coverage in the New York Times, the role of beta oscillations is described as facilitating coordination among different parts of the brain, with intentional movement involving a temporary decrease in synchronization of neurons in the motor cortex. The authors said phase-amplitude coupling might be a biomarker of parkinsonism that could be used as a control signal for a closed-loop neurostimulation system. (New York Times)

Researchers Demonstrate Substance-Releasing, Potentially Implantable, Electrodes

March 26, 2015 - A team of scientists modified bioelectronic sense-and-act systems to create electrodes capable of sensing and substance-releasing functions. A sensing electrode was activated by substances that ranged from small biomolecules to proteins and bacterial cells. Activation generated current and a reductive potential, which, on the second connected electrode, dissolved a matrix cross-linked by positively charged iron moieties (Fe3+). This action released a variety of compounds -- drug-like chemical species, antibacterial agents, and enzymes that activated a biofuel cell. The researchers propose applications for implanted devices that might operate autonomously. (The Journal of Physical Chemistry Letters)

Neural Synchronicity Study Explores Role of Low-Frequency Deep Brain Stimulation

March 25, 2015 - International Neuromodulation Society members Jamie Henderson, MD, and Hong Yu, MD, are among authors of a study that examined intraoperative effects of 60 Hz stimulation during implantation of deep brain stimulation (DBS) leads in the subthalamic nucleus (STN) of Parkinson's disease patients. The authors observed an effect on baseline neural synchronicity. The low-frequency stimulation reinforced or inhibited synchronicity of patient-specific cortico-basal ganglia-thalamic-cortical loop(s) that contribute to the baseline resting state neural synchrony in the STN. It is for this reason, they propose, that effects of 60 Hz DBS may vary from high frequency DBS in different patients on managing such symptoms as either freezing of gait and speech on one hand or tremor on the other. (PLOS One)

A Multimodal Approach to Noninvasive Brain Stimulation is Proposed

March 25, 2015 - Researchers at the University of Minnesota propose a new concept for noninvasively targeting deeper brain structures through activation of various pathways, such as auditory, visual, somatosensory, motor, cognitive and limbic. They activated auditory and somatosensory pathways in guinea pigs and observed differential, timing dependent plasticity in neural firing within the auditory system, both in the deep brain and cortical areas. Their proposed approach would be called Multimodal Synchronization Therapy (mSync). They say incorporating multiple types of pathways using different, precisely timed, activation patterns may enable treatment of various brain disorders. (Scientific Reports)

Multicenter Study Provides Evidence for Deep Brain Stimulation in Dystonia

March 3, 2015 - A multicenter study of 55 dystonia patients who were followed for up to 92 months provided Class IV evidence that long-term deep brain stimulation (DBS) of the internal pallidum improved the condition in patients with monogenic isolated dystonia types DYTi and DYT6, as well as patients without known monogenic cause (non-DYT). The effect of DBS in the eight DYT6 patients appeared less predictable, suggesting that generic testing and counseling for known dystonia gene mutations may be indicated. Regardless of what type of dystonia the patients had, those with a shorter duration between onset and surgery had better control postoperatively. (Neurology)

Researchers Report Successful Outcome of Deep Brain Stimulation in Patients with Genetically-Caused Tremor

March 2015 - Researchers associated with the University of Tübingen report on bilateral deep brain stimulation of the nucleus ventralis intermedius in three patients who had fragile X-associated tremor/ataxia syndrome.

Study: Spinal Cord Stimulation Decreased Moderate, Predominantly Lower-Limb, Spasticity

Feb. 27, 2015 - In a retrospective case series of 71 patients with spasticity who were followed up from 2 to 7 years, a team at the Burdenko Neurosurgery Institute in Moscow found that spinal cord stimulation (SCS) improved symptoms in all 19 patients whose spasticity was caused by spinal injury. Meanwhile, in a group of 52 patients who had spasticity of the lower limbs or all four limbs due to cerebral palsy, only the patients whose spasticity was confined to the lower limbs showed a significant improvement in symptoms. In a small group of patients (11%), the spasticity improved to the point that no further SCS was needed. The authors conclude that this phenomenon should be investigated further.

Research Offers Evidence About Side-Effects of Deep Brain Stimulation in Parkinson's Disease

Feb. 27, 2015 - International Neuromodulation Society members Dr. Yasukazu Kajita and Dr. Masaru Yamamoto and colleagues report in the Journal of Neurology on characteristics of voice and speech disorders associated with subthalamic nucleus (STN) deep brain stimulation (DBS) in Parkinson’s disease patients.
