Autism Terminology Guidelines
The language we use to talk about autism is important. A paper published in our journal (Kenny, Hattersley, Molins, Buckley, Povey & Pellicano, 2016) reported the results of a survey of UK stakeholders connected to autism, to enquire about preferences regarding the use of language. Based on the survey results, we have created guidelines on terms which are most acceptable to stakeholders in writing about autism. Whilst these guidelines are flexible, we would like researchers to be sensitive to the preferences expressed to us by the UK autism community. Preferred language The survey highlighted that there is no one preferred way to talk about autism, and researchers must be sensitive to the differing perspectives on this issue. Amongst autistic adults, the term ‘autistic person/people’ was the most commonly preferred term. The most preferred term amongst all stakeholders, on average, was ‘people on the autism spectrum’. Non-preferred language: 1. Suffers from OR is a victim of autism. Consider using the following terms instead: o is autistic o is on the autism spectrum o has autism / an autism spectrum disorder (ASD) / an autism spectrum condition (ASC) (Note: The term ASD is used by many people but some prefer the term 'autism spectrum condition' or 'on the autism spectrum' because it avoids the negative connotations of 'disability' or 'disorder'.) 2. Kanner’s autism 3. Referring to autism as a disease / illness. Consider using the following instead: o autism is a disability o autism is a condition 4. Retarded / mentally handicapped / backward. These terms are considered derogatory and offensive by members of the autism community and we would advise that they not be used. -

Fragile X Syndrome
European Journal of Human Genetics (2008) 16, 666–672 & 2008 Nature Publishing Group All rights reserved 1018-4813/08 $30.00 www.nature.com/ejhg PRACTICAL GENETICS In association with Fragile X syndrome Fragile X syndrome, an X-linked dominant disorder with reduced penetrance, is associated with intellectual and emotional disabilities ranging from learning problems to mental retardation, and mood instability to autism. It is most often caused by the transcriptional silencing of the FMR1 gene, due to an expansion of a CGG repeat found in the 50-untranslated region. The FMR1 gene product, FMRP, is a selective RNA-binding protein that negatively regulates local protein synthesis in neuronal dendrites. In its absence, the transcripts normally regulated by FMRP are over translated. The resulting over abundance of certain proteins results in reduced synaptic strength due to AMPA receptor trafficking abnormalities that lead, at least in part, to the fragile X phenotype. In brief Genetic testing for this repeat expansion is diagnostic for this syndrome, and testing is appropriate in all Fragile X syndrome is a common inherited form of children with developmental delay, mental retardation mental retardation that can be associated with features or autism. of autism.

Cognitive Impairment and Dementia in Adults with Autism Spectrum Disorder
ARTÍCULO DE REVISIÓN Deterioro Cognitivo y Demencias en Adultos con Trastorno del Espectro Autista Cognitive Impairment and Dementia in Adults with Autism Spectrum Disorder David Toloza Ramírez,1,2 Carolina Iturra Pedreros,3,4 Grisol Iturra Pedreros3,4 Resumen El Trastorno del Espectro Autista (TEA) clásicamente ha sido estudiado en población infantil, no obstante, en la actualidad 1/68 adultos vive con este trastorno del neurodesarrollo. Las personas con TEA en edad adulta manifiestan síntomas sugerentes de deterioro cognitivo, los cuales comprometen rápidamente diversas funciones cognitivas. El deterioro cognitivo y las altera- ciones conductuales favorecen- en personas con TEA- el desarrollo de procesos neurodegenerativos como la demencia Fronto- temporal (DFT) y la demencia tipo Alzheimer (EA), lo cual afecta las actividades de la vida diaria (AVD). El objetivo de esta revisión es investigar la progresión del TEA hacia estados de deterioro cognitivo y cuadros demenciales en edad adulta. Nuestra metodología incluyó análisis cualitativos de investigaciones realizadas desde el año 2000 al 2020 exclusivamente en idioma in- glés. Los resultados demuestran que los adultos con TEA desarrollan deterioro cognitivo y demencias precozmente en relación a la población general, afectando principalmente importantes funciones cognitivas como la memoria y la función ejecutiva. En conclusión, la discapacidad intelectual de grado moderado a profundo, así como las reducciones en la sustancia blanca del ce- rebro, parecen ser uno de los precursores para el desarrollo de deterioro cognitivo y procesos demenciales en adultos con TEA. Palabras clave: Trastorno del Espectro Autista, Adultez, Discapacidad Intelectual, Deterioro Cognitivo, Demencias. Abstract Autism Spectrum Disorder (ASD) has been studied mainly in children. -

High-Functioning Autism Spectrum Disorder And
Chaste et al. Molecular Autism 2012, 3:5 http://www.molecularautism.com/content/3/1/5 RESEARCH Open Access High-functioning autism spectrum disorder and fragile X syndrome: report of two affected sisters Pauline Chaste1,2,3, Catalina Betancur4,5,6, Marion Gérard-Blanluet7, Anne Bargiacchi3, Suzanne Kuzbari7, Séverine Drunat7, Marion Leboyer2,8,9, Thomas Bourgeron1,10,11 and Richard Delorme1,2,3,10* Abstract Background: Fragile X syndrome (FXS) is the most common inherited cause of intellectual disability (ID), as well as the most frequent monogenic cause of autism spectrum disorder (ASD). Men with FXS exhibit ID, often associated with autistics features, whereas women heterozygous for the full mutation are typically less severely affected; about half have a normal or borderline intelligence quotient (IQ). Previous findings have shown a strong association between ID and ASD in both men and women with FXS. We describe here the case of two sisters with ASD and FXS but without ID. One of the sisters presented with high-functioning autism, the other one with pervasive developmental disorder not otherwise specified and low normal IQ. Methods: The methylation status of the mutated FMR1 alleles was examined by Southern blot and methylation- sensitive polymerase chain reaction. The X-chromosome inactivation was determined by analyzing the methylation status of the androgen receptor at Xq12. Results: Both sisters carried a full mutation in the FMR1 gene, with complete methylation and random X chromosome inactivation. We present the phenotype of the two sisters and other family members. Conclusions: These findings suggest that autistic behaviors and cognitive impairment can manifest as independent traits in FXS.
