Responsive Neurostimulator Data Reveal Seizure-Prone Monthly Cycles in Patients with Epilepsy

Jan. 8, 2018 - Data gathered from responsive neurostimulator implants in 37 epilepsy patients, for a median of 2.25 years, show that the patients have both daily cycles in seizure risk, but also longer cycles of rising and falling brain irritability that lasts weeks or months. The researchers published in Nature Communications an analysis that indicates seizure risk is almost seven times greater when the most seizure-prone periods of those cycles overlap. (Science Daily)

Study Evaluates Brain Effects of Non-Invasive Neurostimulation Device

Jan. 8, 2018 - Helius Medical Technologies, Inc. announced that a study in 20 healthy volunteers showed its non-invasive, investigational device that delivers neurostimulation through the tongue exerted statistically significant changes in brainwave activity as observed in EEG. For instance, during a 20-minute rest period following a 20-minute session of high frequency stimulation, alpha and theta brainwaves increased. The study evaluated high frequency and low frequency stimulation, in random order, in single sessions one week apart. (Nasdaq)

Jan. 4, 2018 - Livanova PLC announced it has enrolled its first patient in a post-market study of implanted vagus nerve stimulation as an adjunctive treatment for patients with difficult-to-treat depression. The study, RESTORE-LIFE, will enroll at least 500 patients at up to 80 sites outside the U.S., and follow-up will run from three to five years. (Markets Insider)

Transcranial Direct Current Stimulation Studied in Bipolar Depression

Jan. 4, 2017 - An investigator in Brazil published in JAMA Psychiatry results of a controlled clinical trial of transcranial direct current stimulation in bipolar patients. The study of 52 patients showed that a series of active stimulation sessions during a major depressive episode resulted in 67.6% becoming responders, and 37.4% experiencing remission. In contrast, sham treatment led to a 30.4% responder rate and 19.1% entering remission. (Psych Congress Network)

Magazine Highlights Brain Computer Interface Research

Jan. 4, 2018 - A comprehensive technology feature summarizes recent research into brain computer interfaces. The article says 13 people have been implanted since 2004 with the BrainGate system, designed to provide a degree of intentional movement to people who have been paralyzed, allowing them to complete simple tasks, such as moving a cursor or controlling a limb.

Prototype Portable Prosthetic Hand Provides a Sense of Touch

Jan. 3, 2018 - Scientists in Italy unveiled a prototype prosthetic hand that provides a sense of touch using electronics that are compact enough to fit in a backpack. A patient who used the device for six months was able to distinguish between hard and soft objects while blindfolded, and to use the prosthetic for tasks in which having the tactical feedback is helpful, such as dressing, she said.

Study: Occipital Nerve Stimulation is Potentially Safe and Effective in Refractory Cervicogenic Headache

Jan. 3, 2018 - An article that appeared online Nov. 27, 2017 in Neuromodulation: Technology at the Neural Interface reported a retrospective chart review of 16 patients who were treated with occipital nerve stimulation (ONS) for their daily, moderate-to-severe, refractory cervicogenic headaches. The patients were followed for three years; at one year, 69% were considered responders, and at three years, 37.5% were. (Neurology Advisor)

Translational Study Shows Potential Promise to Address Tinnitus Through Bimodal Stimulation

Jan. 3, 2018 - A double-blinded, sham-controlled, crossover clinical study of bimodal stimulation in adults with tinnitus provided evidence to support a larger clinical trial, according to an interview with the researcher. The approach combines sound and skin stimulation in an intent to target nerve activity in the brain. Animal studies established that phantom sounds are signaled to the brain through fusiform cells.
