We studied 11 patients (9 males) with cytogenetic diagnosis of fragile X syndrome (FXS) with the purpose of investigating the neural circuitry involved in this condition. The ages ranged from 8 to 19. All the individuals presented large ears, elongated faces and autistic features. Ten patients had severe mental retardation. Attention disorder was found in(More)
Dyslexia or reading disability (RD) is the most common childhood learning disorder and a significantly heritable trait. Many recent studies have investigated the genetic basis of dyslexia, and several candidate genes have been proposed. Among these, DCDC2 and KIAA0319 have emerged as the strongest candidate genes for dyslexia; however studies have not(More)
The present study aims to compare the performance between Brazilian children with Developmental Dyslexia (DD) and children without learning difficulties on tests of attention and Executive Functions. The study sample consists of study group (20 subjects) attending the Learning Disability clinic of University Hospital and control group (20 subjects) from(More)
PURPOSE To assess binocular control in children with dyslexia. METHODS Cross-sectional study with 26 children who were submitted to a set of ophthalmologic and visual tests. RESULTS In the dyslexic children less eye movement control in voluntary convergence and unstable binocular fixation was observed. CONCLUSION The results support the hypothesis(More)
We analyzed retrospectively the neuroimaging exams of children with a confirmed diagnosis of dyslexia and correlated our findings with the evaluation of higher cortical functions. We studied 34 medical files of patients of the Ambulatory of Neuro-difficulties in Learning, FCM/UNICAMP. All of them had been sent to the ambulatory with primary or secondary(More)
The clinical and neurological findings of three neonates with the diagnosis of cerebrovascular disease are reported. The neuropsychological evaluation disclosed impairment of fine motor function, coordination, language, perception and behavioral disturbances. Brain SPECT imaging revealed perfusional deficits in the three cases.
Objective. To assess cognitive development and learning in children who have had strokes. Method. Twenty-nine stroke patients and 18 children with no brain lesions and no learning impairments were evaluated. For the cognitive assessment, Piaget's clinical method was used. Writing, arithmetic, and reading abilities were assessed by the school performance(More)
The aim of this study was to characterize a group of patients (n=8) with sickle cell disease (SCD) and ischemic stroke concerning the clinical, neurological, imaging and progressive aspects. Data were collected from records and completed with an interview of patients and their parents. In this study there were 8 patients with ages ranging from 10 to 23(More)
Studies have described changes in visual attention and executive function in children with developmental dyslexia. This study intended to compare the performance of children with and without learning difficulties on tasks of visual attention and executive functions. The participants were 23 students, aged between 9 and 14 years old, with a mean age of 10.8(More)
The purpose of this study is to associate neuropsychological evaluation with neuroimaging results in children with cerebral tomography indicating ischemic cerebrovascular disease (ICVD). Neuroimaging, neurological exams and neuropsychological instruments were used to evaluate five children. The study revealed that the cognitive and perceptive skills in two(More)
