[Autism, neurodevelopment and early detection].

INTRODUCTION: Autistic disorder is briefly explained and defined in the light of recent research. DEVELOPMENT: From the perspective offered by ontogenesis and the acquisitions that take place during normal development, we present an updated vision of the genesis of autistic disorder and also review the most significant data provided by the different studies that have been conducted on the subject. Detection of the disorder is clearly a difficult task before the age of one year and, in any case, the earliest symptoms are clearly linked to the social and communicative interaction that characteristically takes place at the end of the infant's first year of life. CONCLUSION: Early detection of the disorder is made possible precisely because of alterations in social and communicative development and, in general, the appearance of psychological functions that play a significant role in the process of humanisation. The article concludes by pointing out the need for further studies that focus on the possible alteration of earlier socio-emotional and affective manifestations.

[Educational intervention in autism from a psychological point of view].

INTRODUCTION: Autism is the prototypical condition in autism spectrum disorders. It is a developmental disorder of biological origin that becomes apparent by the age of 3 and which is characterised by qualitative alterations affecting the development of social relations and interaction, communication and language, and the development of symbolic and imaginative activity. DEVELOPMENT: The first manifestations of the disorder take place, in most cases and according to the two sources of information currently available (retrospective information provided by the families and the analysis of family videos), around the end of the first year (the age of 18 months is one of the ages most frequently mentioned by the families when asked about the matter). From an ontogenetic point of view, the coincidence between the times of the first manifestations of the disorder and the development of qualitatively human psychological functions is significant. Autism can, therefore, be understood to be a disorder that affects the genesis of psychological factors that are extremely relevant to human development and, thus, educational intervention must necessarily include the construction of these psychological functions as far as this is possible. CONCLUSIONS: Educational treatment in autism and in autism spectrum disorders have to be based on two essential areas of knowledge that must guide the implementation of any intervention programme, i.e. developmental and ontogenetic knowledge of typical development and knowledge of the autistic way of 'being'. The essential part of the treatment carried out in autism lies in the flexible and creative integration of our knowledge in these two areas.

[Autism and hyperlexia].

INTRODUCTION: Hyperlexia is described in children who present alterations or retardation in development and is frequently characterised by their teaching themselves to read at an early age. This ability to decode words does not correlate with their intellectual level and can course with different degrees of mental retardation. It is always accompanied by difficulty in establishing social relationships. Autism is a disorder that is prototypical of the autistic spectrum disorders (ASD), which are essentially characterised by qualitative alterations in social interaction, in communication and language development, and in the presence of a limited repertory of interests, accompanied by stereotyped or peculiar responses. METHOD: The presence of hyperlexia in autistic children is more frequent than in other development disorders. This phenomenon is linked with the increased skills involving visual memory, visual discrimination and motivation/interest towards visually represented material that is to be found in people with autism. However, not all autistic individuals present hyperlexia and not all children with hyperlexia present autism, although evidence shows that hyperlexia is a phenomenon that is observed with greater frequency in autism and in ASD. CONCLUSION: Hyperlexia, understood as meaning a little island of ability in children with autism and ASD, poses a number of questions and represents an important challenge in neuropsychological research in this population.

[The autistic spectrum. An epidemiological study and analysis of possible subgroups].

INTRODUCTION: Although the concept of autistic spectrum may be useful to explain and describe the heterogeneity of the syndrome, its aetiology is still unknown. Different disorders have been reported as the biological basis of autism. Early diagnosis and a multi disciplinary approach to the condition are essential for effective psychopaedagogic treatment. OBJECTIVE: To determine whether there is a relationship between the severity of the syndrome of autism and the course of the disorder, as a function of the presence or absence of neurological features, and to define homogeneous subgroups by detecting etiological variables which may be common to them. PATIENTS AND METHODS: 46 children defined as being within the spectrum of autism, in whom the diagnosis was confirmed on the autistic spectrum inventory (IDEA/Rivi re 97). Parameters studied: family history, perinatal risk, age of onset, complementary investigations and neurological features. RESULTS: The diagnosis was confirmed in 18 children; of the others 14 had a specific defect of the development of language. There was an almost complete absence of underlying neurological disorders, although this may have been due to dispersion of the complementary investigations done. CONCLUSIONS: Specific disorders of the development of language are the main differential diagnoses to be considered together with the autistic spectrum. The diagnosis of autism is clinical, but the heterogeneity of the medical approach interferes with the overall assessment of the spectrum favoring behavioural and underestimating the biological aspects. This means that the problem should be reconsidered so as to obtain uniform guidelines for action.

[Best practice guidelines for the early detection of Autistic Spectrum Disorders (I)].

INTRODUCTION: The interest in early detection of Autism Spectrum Disorders (ASD) lies in the accumulated evidence of the fact that an early customized intervention for children with an ASD and their families leads to an improvement of the child's prognosis in most cases. OBJECTIVE: To establish criteria and procedures for early identification of children at risk of ASD and to facilitate full diagnostic assessment and prompt referral leading to adequate support. Early detection of ASD is extremely important, since early specific individualized treatment for the child and his or her family leads to long-term improvement in many children' prognosis. DEVELOPMENT: Firstly, a critical appraisal of the situation of early detection of ASD in Spain is made after reviewing the scarce bibliography available on current screening and diagnostic practices in the country. Data generated by questionnaires received from 646 Spanish families is also taken into account. Secondly, the Study Group of the Instituto de Salud Carlos III recommends the screening and early diagnosis process to be followed, describing the necessary steps, the public services involved and the available screening and diagnostic tools. CONCLUSIONS: The Study Group draws the main conclusions regarding the situation of ASD early detection in Spain, and makes a consensus proposal for the detection procedures, including routine developmental surveillance and identification of children at risk for ASD by using sensitive and specific assessment tools.

[Best practice guidelines for the diagnosis of autistic spectrum disorders].

INTRODUCTION: The autism spectrum disorder (ASD) diagnostic process requires expertise both in the knowledge of autism as in teamwork strategies with different professionals, often working in different clinic services, and with parents. AIM: To recommend a consensus diagnostic procedure for ASD, that has been designed by the Study Group of the Instituto de Salud Carlos III. DEVELOPMENT: The reports emphasize the need to obtain a complete clinical history, covering personal, family and psychosocial antecedents; detailing the basic areas affected in ASD--social interaction, communication and restricted patterns of behaviour, activities and interests. Diagnostic tests to be used as a routine in all cases are described and analysed--including both psychoeducational and biomedical tests. Also, tests indicated in cases with suspected identifiable physical disorders are covered, as well as those medical tests to be used for research purposes only. CONCLUSION: The diagnostic procedure requires the implementation of a coordinated interdisciplinary assessment strategy, that needs to ensure the participation of professionals from very different fields in active collaboration with the family. Their role culminates in the preparation and delivery of a personalized report. Every diagnostic procedure needs to be accompanied by an action plan that includes immediate support to the person with ASD, as well as information to the family on resources and community initiatives in their living area.

[Best practice guidelines for research in autistic spectrum disorders].

INTRODUCTION: Achieving a better knowledge of autism and other pervasive developmental disorders known as autistic spectrum disorders (ASD), poses a major scientific challenge. These disorders are some of the earliest and most severe psychopathological disorders in infancy; they include an heterogeneous group of conditions; its prevalence rate seems to be continually increasing and they generate a significant social impact. AIMS AND DEVELOPMENT: Nowadays, there is a current international agreement on the general requirements to be fulfilled by research projects and the priority areas to be considered when developing ASD high quality research. In Spain, although there are some established research groups with broad experience and expertise in these disorders, public funding opportunities and research development are still scarce. For this reason, the Study Group of the Instituto de Salud Carlos III has generated by consensus some Good Practice Guidelines for Research in ASD. CONCLUSIONS: After comparing priorities and recommendations from international reference documents with the results obtained after having carried out an exhaustive bibliographic revision of articles published in autism in the last 30 years by Spanish authors, methodological and ethical recommendations are established. Finally, structural deficiencies to be corrected and emerging research initiatives to be supported are identified.

[Good practice guidelines for the treatment of autistic spectrum disorders].

INTRODUCTION: Due to the inexistence of an aetiology-based intervention for autistic spectrum disorders (ASD) families and professionals are exposed to diverse and sometimes conflictive recommendations when they have to decide the most adequate alternative for treatment. AIM: To elaborate treatment guidelines agreed by consensus at the ASD Study Group of the (National) Institute of Health Carlos III. DEVELOPMENT: Information about treatment of ASD was searched and gathered through available evidence based medical (EBM) databases. The data generated was complemented with practice parameters published elsewhere, reports from prestigious international institutions, focus oriented searches in PubMed and, finally, the opinion and experience of a multidisciplinary Study Group with extensive experience in treating ASD in Spain. Most popular treatment methods were reviewed as well as the common elements to be considered in successful support programs. CONCLUSION: No simple treatment algorithm can be produced at this time, and the level of available evidence based recommendations are in the weaker degrees of EBM classifications. Nevertheless, there is widespread agreement to stress that education, with special incidence in the development of communication and social competence, with the addition of community support are the main means of treatment. They can be complemented, depending on individual needs, with medication, behavioural approaches and cognitive-behavioural therapy for associated psychological problems in persons with higher cognitive level. Support to families and community empowerment are essential elements for the quality of life of persons with ASD.
