Language Disorder with Focal Epilepsies

open access: yesPediatric Neurology Briefs, 2002
The relationship between language disorder and epileptic seizures was examined in 109 children, ages 5-17 years, attending a national center for epilepsy over a 4 year period and at the University of Manchester, UK.

Recurrent NEDD4L Variant in Periventricular Nodular Heterotopia, Polymicrogyria and Syndactyly

open access: yesFrontiers in Genetics, 2020
NEDD4L encodes an ubiquitin ligase which is expressed in the cortex and ventricular zone of the fetal brain. Missense variants in NEDD4L have been reported in nine patients with periventricular nodular heterotopia (PNH), polymicrogyria, cleft palate, and

Neuronal migration disorders

open access: yesNeurobiology of Disease, 2010
Lissencephaly–pachygyria-severe band heterotopia are diffuse neuronal migration disorders (NMDs) causing severe, global neurological impairment. Abnormalities of the LIS1, DCX, ARX, TUBA1A and RELN genes have been associated with these malformations ...

Specific language impairment: linguistic and neurobiological aspects Distúrbio específico de linguagem: aspectos linguísticos e neurobiológicos

open access: yesArquivos de Neuro-Psiquiatria, 2006
Specific language impairment (SLI) occurs when children present language maturation, at least 12 months behind their chronological age in the absence of sensory or intellectual deficits, pervasive developmental disorders, evident cerebral damage, and ...

Clinical and Functional Characterization of the Recurrent TUBA1A p.(Arg2His) Mutation

open access: yesBrain Sciences, 2018
The TUBA1A gene encodes tubulin alpha-1A, a protein that is highly expressed in the fetal brain. Alpha- and beta-tubulin subunits form dimers, which then co-assemble into microtubule polymers: dynamic, scaffold-like structures that perform key functions ...

The evaluation of unilateral closed-lip schizencephaly on complex MRI sequences [PDF]

open access: yesRomanian Journal of Neurology, 2021
Schizencephaly is one of the rare cortical malformations that classify in the group of neurological migration defects. The appearance of the anomaly is in the form of a cleft that passes through the brain parenchyma.

COL4A1 mutation‐related disorder presenting as fetal intracranial bleeding, hydrocephalus, and polymicrogyria

open access: yesEpilepsia Open, 2023
Fetal intracranial hemorrhage represents a rare event with an estimated prevalence of 1:10 000 pregnancies. We report a patient diagnosed prenatally with intracranial hemorrhage and ventriculomegaly carrying a novel, previously unreported, likely ...

Multiple Stereoelectroencephalography-Guided Radiofrequency Thermocoagulations for Polymicrogyria With Startle Seizures: A Case Report

open access: yesFrontiers in Neurology, 2019
The best results of stereoelectroencephalography (SEEG)-guided radiofrequency thermocoagulation (RF-TC) were observed in epilepsies with more limited lesions, but this procedure is rarely used in a wide range of brain malformation.
