1. Auditory processing assessment in the perisylvian syndrome / Caracterização dos achados da avaliação do processamento auditivo na Sindrome Perysylviana
Perisylvian syndrome (PS) comprises a variety of clinical manifestations due to lesions on the perisylvian or opercular regions. Bilateral perisylvian polymicrogyria is a malformation of cortical development characterized by excessively small gyri seen around the Sylvian fissure on magnetic resonance imaging. Studies suggest that language and learning impair

2. Measurement of cortical thickness using magnetic resonance imaging: technique and applications in Alzheimers disease and polymicrogyria / Medida da espessura cortical com imagens de ressonância magnética: técnica e aplicações na doença de Alzheimer e na polimicrogiria
As técnicas de morfometria baseadas em imagens ressonância magnética desde o início do século XXI tem sido uma importante ferramenta para estudar doenças neurológicas. Um dos benefícios desta técnica é prover medidas de parâmetros que manualmente são difíceis de estimar e com um grande viés de operador. Este trabalho teve como objetivo descreve

3. Disturbios do desenvolvimento cortical e epilepsia autossomica dominante com auras auditivas : estudos geneticos e moleculares / Malformations of cortical development and autosomal dominant partial epilepsy with auditory features
Temporal Lobe Epilepsy (TLE) and malformations of cortical development (MCD) are two of the most important causes of epilepsy. Extensive molecular genetic studies have resulted in gene discovery for MCD such as periventricular nodular heterotopia (PNH), lisencephaly/ subcortical band heterotopia spectrum (LIS-SBH), schizencephaly, polymicrogyria and for a su

4. Alterações de linguagem em familias com sindome perisylviaia / Language disrder in families with Perisylvian Syndome
Specific language impairment (SLI) refers to inadequate language development in a child without other development disorder, that is, inadequate language acquisition is the main difficulty, even if the child may present with other symptoms. SLI may occur in patients who have polymicrogyria around Sylvian fissure on neuroimaging studies (perisylvian syndrome).

5. Aspectos clinicos e neurofisiologicos das polimicrogirias / Clinical and electroencephalographic features of patients with polymicrogyria
Polimicrogiria é uma malformação da organização cortical que se caracteriza por múltiplos pequenos giros separados por espessos e rasos sulcos. O objetivo do presente estudo foi descrever as manifestações clínicas e eletroencefalográficas de pacientes com polimicrogiria, que têm epilepsia e/ou distúrbio específico de linguagem e dos familares do

6. Estudo molecular e de correlação genotipo-fenotipo na polimicrogiria perisylviana bilateral congenita
Polimicrogiria (PMG) é uma malformação comum do desenvolvimento cortical caracterizada por um número excessivo de pequenos giros e laminação anormal, dando à superfície cortical uma aparência irregular e grosseira. A gravidade das manifestações clínicas se correlaciona com a extensão do envolvimento cortical. As lesões bilaterais ou unilaterais

7. Malformações do desenvolvimento cortical : contribuição dos fatores geneticos e ambientais para sua etiologia, aspectos clinicos e de neuroimagem
Rationale - Malformations of cortical deve10pment (MCD) can be associated with hippocampal abnormalities. Our objective was to assess whether different hippocampal abnormalities are associated with a particular class ofMCD. Methods - We evaluated 83 consecutive patients with MRI diagnosis ofMCD (37 men, ages ranging ttom 2 to 58 years; mean=18.5). High resol

8. Displasias corticais associadas a epilepsia : delineamento de uma nova sindrome, revisão de conceitos localizacionais e proposta de uma nova classificação
Modemneuro:imagingtechniques current1y allows lin vivo I identification of cortical dysplastic lesions in patients previously thought to have cryptogenic epilepsies. These lesions constitute an heterogenous group of disorders from clinicall anatomical, histopathological, and pathogenetic standpoints. The fact that such heterogeneity is not readily realized o

9. An Autosomal Recessive Form of Bilateral Frontoparietal Polymicrogyria Maps to Chromosome 16q12.2-21
Polymicrogyria is a cerebral cortical malformation that is grossly characterized by excessive cortical folding and microscopically characterized by abnormal cortical layering. Although polymicrogyria appears to have one or more genetic causes, no polymicrogyria loci have been identified. Here we describe the clinical and radiographic features of a new geneti

10. A Locus for Bilateral Perisylvian Polymicrogyria Maps to Xq28
Polymicrogyria (PMG) is one of a large group of human cortical malformations that collectively account for a significant percentage of patients with epilepsy, congenital neurological deficits, and intellectual disability. PMG is characterized by an excess of small gyri and abnormal cortical lamination. The most common distribution is bilateral, symmetrical,

12. Syndrome of absent abdominal muscles: two cases with microcephaly, polymicrogyria, and cerebellar malformations
Two unique cases of the syndrome of absent abdominal muscles with central nervous system involvement are presented. Microcephaly, polymicrogyria, and cerebellar heterotopiae were present in both. In case 1 there was also absence of the corpus callosum and agenesis of the cerebellar vermis. In case 2 a count of anterior horn cells in the spinal cord showed a
