Epilepsy surgery: eligibility criteria and presurgical evaluation
Epilepsy surgery has benefited from major advances during the last 20 years, thanks to the development of neuroimaging and long-term video-electroencephalographic (EEG) monitoring. However, it remains the case that only a small minority of potential epilepsy surgery candidates will have access to a comprehensive presurgical evaluation. Furthermore, this subset of patients are operated on after ...
full textPresurgical evaluation and outcome of epilepsy surgery in childhood
Surgery in the management of children with epilepsy is not new. Murray Falconer, a neurosurgeon at the Maudsley Hospital, recognised that children as well as adults may benefit from resective surgery, but the age range of his patients did not include the very young1. Traditionally, focal seizures have been more difficult to diagnose in the young child, both clinically and electrographically, an...
full textPresurgical evaluation of epilepsy.
An overview of the following six cortical zones that have been defined in the presurgical evaluation of candidates for epilepsy surgery is given: the symptomatogenic zone; the irritative zone; the seizure onset zone; the epileptogenic lesion; the epileptogenic zone; and the eloquent cortex. The stepwise historical evolution of these different zones is described. The current diagnostic technique...
full textMagnetoencephalography in the presurgical evaluation of epilepsy.
Magnetoencephalography (MEG) is an important tool in the presurgical evaluation of patients with medically refractory epilepsy. The appropriate utilization and interpretation of MEG studies can increase the proportion of patients who may be able to further pursue surgical evaluation, refine surgical planning, and potentially increase the probability of seizure freedom after surgery. The aim of ...
full textSignificance of MEG in Presurgical Epilepsy Evaluation
Magnetoencephalography (MEG), as a non-invasive procedure, records magnetic fields generated by spontaneous or evoked brain activity. Presurgical evaluation of pharmacoresistent patients with focal epilepsy is currently the most frequent diagnostic application. The source of epileptic or averaged evoked activity is localised and then overlaid onto magnetic resonance imaging (MRI) of the patient...
