Purpose: To investigate whether rhythmic direct electrical stimulation (DES) causes entrainment of endogenous neural oscillatory activity and whether such activity improve cognition. ...
Genetic abnormalities in focal epilepsies are well known. A novel gene (DEPDC5) was identified, associated with various genotypes of epilepsies. Recently, DEPDC5 mutations were identified ...
Focal cortical dysplasia (FCD) is a common finding in epilepsy surgery in pediatric patients. Children with intractable epilepsy would have extensive tests to identify the cause of epilep...
The main purpose of this research project is to evaluate the safety and effectiveness of a surgically implanted device called the Medtronic Activa PC+S System in patients with medically re...
This is a prospective, randomized, double-blind, placebo-controlled cross over study designed to evaluate the efficacy and safety of everolimus (trough 5-15 ng/mL) given as adjunctive ther...
A Multimodal Approach For Radical Excision Of Focal Cortical Dysplasia By Combining Advanced Mri Data To Intraoperative Ultrasound, Electrocorticography And Cortical Stimulation: A Preliminary Experience.
Type II focal cortical dysplasia is the most common malformation of cortical development associated with drug resistant epilepsy and susceptible to surgical resection. Although advanced imaging modali...
Electrical stimulation has been widely used in many ophthalmic diseases to modulate neuronal activities or restore partial visual function. Due to the different processing pathways and mechanisms, res...
Cortical electrical stimulation mapping is often required to accurately delineate eloquent function before resective surgery for tumors or epilepsy. Although the technique is well established in adult...
Loss-of-function mutations in a single allele of the gene encoding DEP domain-containing 5 protein (DEPDC5) are commonly linked to familial focal epilepsy with variable foci; however, a subset of pati...
We report the surgical management of a lesional drug-resistant epilepsy caused by a meningioangiomatosis associated with a type IIIc focal cortical dysplasia located in the left supplementary motor ar...
A disorder characterized by recurrent partial seizures marked by impairment of cognition. During the seizure the individual may experience a wide variety of psychic phenomenon including formed hallucinations, illusions, deja vu, intense emotional feelings, confusion, and spatial disorientation. Focal motor activity, sensory alterations and AUTOMATISM may also occur. Complex partial seizures often originate from foci in one or both temporal lobes. The etiology may be idiopathic (cryptogenic partial complex epilepsy) or occur as a secondary manifestation of a focal cortical lesion (symptomatic partial complex epilepsy). (From Adams et al., Principles of Neurology, 6th ed, pp317-8)
The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.
Cortical malformations secondary to abnormal cortical maturation after CELL MIGRATION in NEUROGENESIS. This group includes injury to the cortex during later stages of cortical development such as POLYMICROGYRIA and focal cortical dysplasias.
Measurable changes in activities in the CEREBRAL CORTEX upon a stimulation. A change in cortical excitability as measured by various techniques (e.g., TRANSCRANIAL MAGNETIC STIMULATION) is associated with brain disorders.
An adjunctive treatment for PARTIAL EPILEPSY and refractory DEPRESSION that delivers electrical impulses to the brain via the VAGUS NERVE. A battery implanted under the skin supplies the energy.
