Focal cortical dysplasia – review
Focal cortical dysplasia is a malformation of cortical development, which is the most common cause of medically refractory epilepsy in the pediatric population and the second/third most common etiology of medically intractable seizures in adults.Both genetic and acquired factors are involved in the pathogenesis of cortical dysplasia. Numerous classifications of the complex structural abnormalit...
متن کاملFocal Cortical Dysplasia.
Focal cortical dysplasias are common malformations of cerebral cortical development and are highly associated with medically intractable epilepsy. They have been classified into neuropathological subtypes (type Ia, Ib, IIa, IIb, and III) based on the severity of cytoarchitectural disruption--tangential or radial dispersion, or loss of laminar structure--and the presence of unique cells types su...
متن کاملCortical development and focal cortical dysplasia.
A brief survey of cortical development is presented, focusing on neuronal migration and its alterations. Corticogenesis is achieved through ordered temporospatial steps, via the formation of transient structures, and successive waves of cell proliferation and migration (followed by cell differentiation and maturation), and apoptotic cell death. The appearance of the proliferative ventricular zo...
متن کاملContributions of EEG-fMRI to Assessing the Epileptogenicity of Focal Cortical Dysplasia
Purpose: To examine the ability of the BOLD response to EEG spikes to assess the epileptogenicity of the lesion in patients with focal cortical dysplasia (FCD). Method: Patients with focal epilepsy and FCD who underwent 3T EEG-fMRI from 2006 to 2010 were included. Diagnosis of FCD was based on neuroradiology (MRI+), or histopathology in MRI-negative cases (MRI-). Patients underwent 120 min EEG-...
متن کاملDissociation between in vitro and in vivo epileptogenicity in a rat model of cortical dysplasia.
OBJECTIVE Malformations of cortical development are frequent causes of human refractory epilepsy. The freeze-lesion model in rats shows histopathological features similar to those found in human polymicrogyria. Previous studies reported in vitro hyperexcitability in this model, but in vivo epileptogenicity has not been confirmed. METHODS Neocortical freeze lesions were induced in Sprague-Dawl...
