Comparison of dense array EEG with simultaneous intracranial EEG for Interictal spike detection and localization

Epilepsy Research, 2011
To evaluate the clinical utility of dense array electroencephalography (dEEG) for the detection yield and localization of interictal spikes in mesial temporal lobe epilepsy.We simultaneously recorded 256-channel dEEG and intracranial electroencephalography (icEEG) implanted over the lateral and mesial temporal lobe in patients with intractable epilepsy.

Machine Learning for Deep Brain Stimulation Efficacy using Dense Array EEG

2019 12th International Conference on Human System Interaction (HSI), 2019
Deep brain stimulation (DBS) is well recognized as an effective treatment for symptoms of movement disorders such as Parkinson's disease (PD), Essential Tremor, and dystonia. The selection of the appropriate contact on the DBS lead for optimal clinical efficacy can be challenging, particularly when considering directional leads.

S17-4. Dense array EEG – Clinical application in epilepsy

Clinical Neurophysiology, 2013
The purpose of this study is to evaluate the clinical usefulness of dense array EEG (dEEG) for spike detection yield ("sensitivity") and localization ("accuracy") of interictal spikes in temporal lobe epilepsy. The subjects were 6 patients who had implanted subdural electrodes in both mesial and lateral temporal regions for presurgical work-up ...

Dynamic imaging of ictal rhythmic activity using dense-array EEG

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Electroencephalogram (EEG) is an important component of the pre-surgical evaluation in the treatment of medically intractable epilepsy. However, clinical EEG uses 19 to 32 electrodes that significantly limits its localization ability. Recent development of dense-array recording techniques has suggested that increased spatial sampling rate improves the ...

Localization of Extratemporal Seizure with Noninvasive Dense-Array EEG

Pediatric Neurosurgery, 2008
A 13-year-old girl presented with refractory seizures since the age of 5 years. Clinical exam and MRI studies were normal. Ictal EEG discharges suggested possible left posterior quadrant distribution but were not well localized with standard methods. A seizure was recorded during 128-channel EEG video long-term monitoring prior to invasive recordings ...

F92. Dense array EEG utilization in outpatient clinic: 788 Cases

Clinical Neurophysiology, 2018
Introduction Dense array EEG (dEEG) covers entire scalp surface by 128 or 256 leads, with shorter inter-electrode distance, making a better spatial resolution. It has been utilized only in selected cases for intractable seizure and a part of the presurgical evaluation.

Dense array EEG estimated the epileptic focus in a patient with epilepsy secondary to tuberous sclerosis complex

Brain and Development, 2018
Tuberous sclerosis complex (TSC) is a leading cause of epilepsy, with seizures affecting almost 80-90% of children. We used the concordance between magnetic resonance imaging (MRI) and dense array electroencephalography (dEEG) findings to detect epileptic focus in a patient with TSC.A 9-year-old boy with TSC exhibited daily choking spells.

Abstract W P387: Neurological Correlates Of Brain Function After Acute Stroke--A Dense Array EEG Study

Stroke, 2015
INTRODUCTION: Measures of brain function can complement assessment of injury to inform clinical decision-making after stroke, but the most useful metrics remain uncertain. An acute stroke alters brain function in widespread areas.

Artifacts EEG during Dense Array EEG (256 channels) acquisition: a comparisons with the 10-20 standard system. [PDF]

, 2013
Purpose In order to better differentiate between what is genuine neuronal activity and what is not, we deploye a method to better understand the topographic field distribution of EEG artifacts i.e.the 256 channel EEG. Because of the profuse number of zygomatic, sovraorbitary, upper cervical and upper margin jaw electrodes, we can better distinguish the

Discriminating schizophrenia disease progression using a P50 sensory gating task with dense-array EEG, clinical assessments, and cognitive tests

Expert Review of Neurotherapeutics, 2019
Schizophrenia affects approximately 10% of the world's population. Early detection of schizophrenia may significantly delay its progression. Although sensory gating deficits are reported in schizophrenia, it remains challenging how sensory gating deficits can be used with other metrics for risk detection and early diagnosis.Using EEG, the authors ...
