Volumetric study of brain MRI in a cohort of patients with neurotransmitter disorders.

Purpose: Inborn errors of neurotransmitters are rare monogenic diseases. In general, conventional neuroimaging is not useful for diagnosis. Nevertheless, advanced neuroimaging techniques could provide novel diagnosis and prognosis biomarkers.

Study of the Interaction between Executive Function and Adaptive Behavior at School in Girls with Fragile X Syndrome.

The aim of this research is to analyze the relationship between executive functions and adaptive behavior in girls with Fragile X syndrome (FXS) in the school setting. This study is part of a larger investigation conducted at the Hospital Parc Tauli in Sabadell. The sample consists of a total of 40 girls (26 with FXS and 14 control) aged 7-16 years, who were administered different neuropsychological tests (WISC-V, NEPSY-II, WCST, TOL) and questionnaires answered by teachers (ABAS-II, BRIEF 2, ADHD Rating Scale).

Pilot study of socio-emotional factors and adaptive behavior in young females with fragile X syndrome.

Girls with Fragile-X-Syndrome (FXS) present high levels of social anxiety, social avoidance, extreme shyness, tendency to social isolation, poor eye contact, learning difficulties, and depression. The aims of the present study, which is based on a group of young females with FXS are: 1) to analyze the possible associations between emotion recognition, theory of mind, and social anxiety, and adaptive behavior, and emotional state; 2) to study the relationship between intelligence quotient (IQ) and adaptive behavior; and 3) to assess whether social anxiety is more prevalent in girls with FXS. The study has 40 female participants aged between 7 and 16 years (26 positive full mutation FXS and 14 as a control group).

Fragile X syndrome in young females: Influence of executive function on the neurocognitive profile and adaptive behavior.

Introduction: The aim of this study is to describe the relationship between executive function (EF) and performance in different areas of the neurocognitive profile in young girls with Fragile-X-Syndrome (FXS).

Method: A neuropsychological assessment was carried out to 40 female participants aged 7-16 years (26 FXS, 14 control group).

Results: Regarding intellectual ability, in the group of girls with FXS 3.

Language in young females with fragile X syndrome: Influence on the neurocognitive profile and adaptive behavior.

Fragile X syndrome (FXS) is the leading cause of inherited intellectual disability. The objective of this research is to analyze the relationship between linguistic functions and performance of the following neuropsychological functions: executive, quantitative reasoning, social perception, behavior, social skills, and adaptive behavior. A neuropsychological and behavioral evaluations were carried out with a group of 26 girls with FXS, and 14 girls without FXS as a control group, using standardized tests.

Bullying Victimization in Young Females with Fragile-X-Syndrome.

The aim of this study is to investigate the risk associated with girls with fragile X syndrome (FXS) suffering bullying in the role of a victim and its effects on their adaptive behavior, socialization style, and emotional state. A neuropsychological assessment was carried out on a sample of 40 participants (26 FXS positive and 14 control group) using the following instruments: WISC-V, SENA, BAS-2, ABAS-II. The results show that the group of girls with FXS presented higher ratios of lack of social support and isolation from classmates.

Analysis of the Phenotypes in the Rett Networked Database.

Rett spectrum disorder is a progressive neurological disease and the most common genetic cause of intellectual disability in females. is the major causative gene. In addition, and mutations have been reported in Rett patients, especially with the atypical presentation.

Rett networked database: an integrated clinical and genetic network of Rett syndrome databases.

Rett syndrome (RTT) is a neurodevelopmental disorder with one principal phenotype and several distinct, atypical variants (Zappella, early seizure onset and congenital variants). Mutations in MECP2 are found in most cases of classic RTT but at least two additional genes, CDKL5 and FOXG1, can underlie some (usually variant) cases. There is only limited correlation between genotype and phenotype.

Reflex seizures in Rett syndrome.

Reflex seizures are a rare phenomenon among epileptic patients, in which an epileptic discharge is triggered by various kinds of stimuli (visual, auditory, tactile or gustatory). Epilepsy is common in Rett syndrome patients (up to 70%), but to the authors' knowledge, no pressure or eating-triggered seizures have yet been reported in Rett children. We describe three epileptic Rett patients with reflex seizures, triggered by food intake or proprioception.
