Company Evaluates Response of Stroke Patients to Different Forms of Noninvasive Stimulation

March 31, 2016 - Nexstim Plc of Finland plans to file for FDA 510(k) clearance for its navigated repetitive transcranial magnetic stimulation system in the second quarter of 2016, the company announced. The system is CE marked, and was undergoing a clinical trial at 12 centers in the U.S. to augment post-stroke arm and hand motor rehabilitation. The sham group received a different stimulation than the patients in the active-treatment arm. After 138 patients were treated, the study reached a futility criterion because both the sham and treatment groups showed clinically meaningful gains, with more than two-thirds of patients in each group responding. The company is filing a patent application on the sham stimulation method, based on this unexpected response. The company is halting the clinical trial and will unblind the data for further analysis.

Mice Studies Indicate Astrocytes Help Mediate Effects of Transcranial Direct Current Stimulation

March 22, 2016 - Researchers in Japan report in Nature Communications on an apparent mechanism of action of transcranial direct current stimulation (tDCS), seen in mouse studies. Fluorescent tagging indicated tDCS induced large surges of calcium ions in astrocytes, implicating activity of these non-nerve cells in mediation of neuronal responses to the stimulation. They add that there were no obvious changes in the local field potential. They suggest this tDCS mechanism may play a role in lowering symptoms of depression and increasing learning and brain plasticity. In a mouse model of stress-induced depression, tDCS normally reduces depression-like behavior. However, when astrocytic calcium surges were blocked, it did not. The researchers also found tDCS enhanced cortical responses to sensory input, such as light flashes or whisker deflection. (EurekAlert)

He said, "spinal cord stimulation can reduce the emotional connectivity and processing in certain areas of the brain in those with chronic pain." The researchers examined functional MRI scans of 10 patients who had spinal cord stimulation (SCS) for complex regional pain syndrome or chronic leg pain. The findings suggest SCS reduces negative pain processing through decreasing connectivity of the limbic and somatosensory areas. (EurekAlert)

Brain Stimulation Boosted Recall of a Short-Term Memory in a Mouse Model of Alzheimer's Disease

March 16, 2016 - Optogenetic studies in a mouse model of Alzheimer's disease showed that stimulation of the hippocampus can elicit recall of an earlier painful stimulus (a box that delivered an electric shock). Normal mice learned to fear the box, but the mice designed to model Alzheimer's disease did not. When the memory-impaired mice received the brain stimulation, however, they did not move about the box, indicating they associated it with the shock. Cycling the simulation on and off as might occur naturally during repeated memory recall allowed the mice to retain and retrieve the memory, and dissection later indicated that repeated stimulation led to more connections between the hippocampus and the entorhinal cortex. (Nature)

Study: Noninvasive Brain Stimulation Enhanced Motor Recovery

March 16, 2016 - A controlled study of transcranial direct current stimulation (tDCS) during stroke rehabilitation in 24 patients showed that the half who received active stimulation in conjunction with nine days of motor rehabilitation performed better at three months' followup than those who did not.

Computational Model Seeks to Help Guide and Explain Deeper Stimulation from Transcranial Magnetic Stimulation

April 2016 - A research team has modeled the brain's white fiber tracts, that connect cortical and subcortical regions and are theorized to potentially propagate action potentials toward deeper brain regions during transcranial magnetic stimulation. Their model, they say, combines electromagnetism and electrophysiology by computing, next to the induced electric fields in the brain, the spatial distribution of the membrane potentials along the fiber tracts and its dynamics over time. By factoring in the location and orientation of the coil, specific results for a patient or a case can be obtained. (Journal of Neural Engineering)

Study Suggests Brain-Hemisphere Dominance May Influence Stimulation Effects

Feb. 29, 2016 - An abstract presented at the annual meeting of the American Association for the Advancement of Science suggests that noninvasive brain-stimulation treatments for depression should be tailored to the dominant hemisphere of the patient, as reflected in their handedness. In the research, 25 subjects who do not have depression were randomized to receive transcranial direct current stimulation (tDCS) to either the right or left side of the head. The subjects had a spectrum of hand preference, with four strongly preferring to use their left hand. After five days of tDCS sessions,  tDCS to the left hemisphere -- the typical approach -- resulted in right-handers feeling better and left-handers feeling worse, while the reverse was true for stimulation of the right hemisphere, according to the article.

European Researchers Examine Neuroendocrine Changes in Deep Brain Stimulation for Obsessive Compulsive Disorder

Jan. 26, 2016 - Researchers report that resuming deep brain stimulation (DBS) in patients with treatment-resistant obsessive compulsive disorder led to rapid release of the neuroendocrine factors prolactin and thyroid-stimulating hormone (TSH). The authors say the findings suggest that DBS is capable of inducing rapid psychiatric symptom changes through an alternative or additional underlying mechanism. For instance, seeing the increase in prolactin and TSH leads them to believe the observed acute mood elevation may be due to stimulation of hypothalamic thyrotropin-releasing hormone. They add that one patient who had previously become a DBS non-responder found some relief of his affective symptoms during the day by switching the DBS off at night and resuming it in the morning, thereby recreating a short-term acute stimulation effect.
