Researches and researchers Currently, we don't have any information about doctors, researches or researchers related to this disease. There seem to be both neurodevelopmental abnormalities and possible premature Focal cortical dysplasia of Taylor's balloon cell type: a clinicopathological entity with characteristic neuroimaging and histopathological features, and favorable postsurgical outcome. FCORD2 is a severe form, with onset usually in childhood, characterized by disrupted cortical lamination and specific cytological abnormalities. GABAergic neuronal abnormalities and K-Cl cotransporter type 2 (KCC2) immaturity may be contributing factors for FCD-related epilepsy. Successful surgery for epilepsy due to early brain lesions despite generalized EEG findings. Includes cortical dyslamination, cytoarchitectural changes and white matter abnormalities. Clinical characteristics in focal cortical dysplasia: a retrospective evaluation in series of 120 patients. Clinical MRI in children and adults with focal epilepsy: a critical review. This study aimed to elucidate whether 3T MRI offers better detection and characterization of FCD2 than 1.5T, using similar coils and acquisition time. Ictal perfusion patterns associated with single MRI-visible focal dysplastic lesions: implications for the noninvasive delineation of the epileptogenic zone.

Neurofibromatosis type 2 (NF2) is a neurocutaneous disorder caused by mutations in the NF2 gene.1 In children, the clinical presentation of NF2 is much more varied compared to adults. Abnormal development of the human cerebral cortex: genetics, functional consequences and treatment options. the clinic, in vivo identification by use of MRI is important. It corresponds to Taylor-type focal cortical dysplasia, according to recent classifications, 1,2 a more homogeneous pathologic entity than other subtypes of cortical dysplasia, especially type 1 FCD. Epileptogenesis in pediatric cortical dysplasia: the dysmature cerebral developmental hypothesis. treatment can be curative in many cases. As FCD type II cannot be diagnosed with certainty in Roux J.-F. Meder B. Devaux C. Oppenheim BACKGROUND AND PURPOSE: Type 2 FCD is one of the main causes of drug-resistant partial epilepsy. Focal cortical dysplasia (FCD) Localized malformations of the cortex. Objective: To analyze the clinical presentation and outcomes of surgically treated focal cortical dysplasia (FCD) in children. Stereoelectroencephalography in presurgical assessment of MRI-negative epilepsy. Focal cortical dysplasia: a genotype-phenotype type analysis of polymorphisms and mutations in the TSC genes. Rapamycin suppresses seizures and neuronal hypertrophy in a mouse model of cortical dysplasia. Remission of epilepsy after two drug failures in children: a prospective study. Figure 1. Can early postnatal closed head injury induce cortical dysplasia. New-onset temporal lobe epilepsy in children: lesion on MRI predicts poor seizure outcome. Among the 16 reclassified cases, MCD was found to be the most common initial diagnosis. Defining the spectrum of international practice in pediatric epilepsy surgery patients. Activation of Akt independent of PTEN and CTMP tumor-suppressor gene mutations in epilepsy-associated Taylor-type focal cortical dysplasias. Focal dysplasia of the cerebral cortex in epilepsy. FCD type 2 patients were more prominently MR positive (77.8% vs. 53.8%. Seizure onset occurs typically in childhood with a majority presenting in the first decade of life (Fauser et al., 2006). On the coronal sequences, the apex of the lesion points towards the ventricle with thin linear increased T2/FLAIR extending to the ependymal surface of the left lateral ventricle. Purpose: To assess the localizing value of 18 F-FDG PET in patients operated on for drug-resistant epilepsy due to focal cortical dysplasia type 2 (FCD 2). GABAergic neuronal abnormalities and K-Cl cotransporter type 2 (KCC2) immaturity may be contributing factors for FCD-related epilepsy.
