NeuroPace RNS System for Epilepsy Gets FDA Approval for MRI Labeling

Mountain View-based NeuroPace today announced it has received FDA approval for MRI labeling for its RNS System, a closed-loop brain-responsive neurostimulation system designed to prevent seizures in adults refractory to antiseizure medications. The a...

Conclusion: Anti-GABA-B receptor encephalitis mainly occurred in middle-aged and elderly men, and the disease onset was relatively sudden. Before disease onset, some patients experienced fever and non-specific respiratory symptoms, which mainly manifested as frequent epileptic seizures, cognitive dysfunction, and abnormal mental behavior. MRI and PET-CT revealed abnormal signals and local metabolism, respectively, in the temporal lobe. Moreover, the disease has a close relationship with lung cancer, which requires long-term follow-up observation.

Conclusion: Integrating preoperative nTMS motor mapping in treatment planning allowed us to reduce dose distributions to perilesional motor fibers while achieving salvage of motor function, lasting seizure freedom, and tumor control. These initial data along with our review of the available literature suggest that nTMS can be of significant assistance in brain radiosurgery. Prospective studies including larger number of patients are still warranted. PMID: 32257555 [PubMed - as supplied by publisher]

Authors: Mégevand P, Seeck M Abstract Introduction: Electric source imaging (ESI) refers to the estimation of the cerebral sources of electric signals recorded at the head surface using electroencephalography (EEG). Thanks to the availability of EEG systems with high numbers of electrodes and to progress in software to analyze the signals they collect, ESI can be applied to epilepsy-related pathological EEG signals like interictal spikes and seizures.Areas covered: In this narrative review, we discuss selected original research articles on the use of ESI in epilepsy patients considered for surgery. Epilepsy-...

CONCLUSION: These results indicated that children with BECTS with ESES showed brain activity altered in the CEN and the SN. The difference of impairment in the SN and CEN may lead to improve the understanding of the underlying neuropathophysiology, and to assess the activity of patients with BECTS with ESES, which is crucial for measuring disease activity, improving patient care, and assessing the effect of antiepilepsy therapy.

NeuroPace is spicing up the neuromodulation market a bit with a new nod from FDA for MRI labeling for the RNS system. The Mountain View, CA-based company’s RNS System treats patients living with seizures that do not respond to medication and first landed a PMA in November of 2013. In a release, the company said individuals with focal onset seizures that also have brain anomalies that require monitoring, such as tuberous sclerosis, brain tumors or multiple sclerosis, as well as those with non-brain MRI requirements, can now be offered the RNS System as a treatment option. The company added this will also a...

Publication date: Available online 21 February 2020Source: Biocybernetics and Biomedical EngineeringAuthor(s): Ashima Khosla, Padmavati Khandnor, Trilok ChandAbstractElectroencephalogram (EEG) measures the neuronal activities in the form of electric currents that are generated due to the synchronized activity by a group of specialized pyramidal cells inside the brain. The study presents a brief comparison of various functional neuroimaging techniques, revealing the excellent neuroimaging capabilities of EEG signals such as high temporal resolution, inexpensiveness, portability and non-invasiveness as compared to the other ...

CONCLUSIONS: The literature describes abnormalities in cranial magnetic resonance imaging in 10-20% of diagnosed cases of PS in which a scan is performed, although the diagnosis of PS is not always changed (matching lesions). Both cases exemplify the importance of reaching a correct diagnosis through a detailed study that must include neuroimaging, since, in some patients, causal brain injuries will be detected and as a result the diagnosis, treatment and evolution will be significantly different.

The objective of the study was to identify the relationship between subcortical gray matter (GM) volumes and juvenile myoclonic epilepsy (JME).MethodsWe analyzed the brain magnetic resonance imaging (MRI) scans that were performed during the time of the diagnosis of epilepsy by using voxel-based morphometry (VBM) method. The volumetric three-dimensional sequence was used for structural investigation. The volumes of the thalamus, caudate nucleus, pallidum, and putamen were measured in both hemispheres of patients with JME, patients with generalized tonic–clonic seizures alone (GTCS) (as a disease control group) and he...
