Audiovisual Multisensory Integration in Individuals with Autism Spectrum Disorder: A Systematic Review and Meta-Analysis

Publication date: Available online 1 October 2018Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Jacob I. Feldman, Kacie Dunham, Margaret Cassidy, Mark T. Wallace, Yupeng Liu, Tiffany G. WoynaroskiAbstractAn ever-growing literature has aimed to determine how individuals with autism spectrum disorder (ASD) differ from their typically developing (TD) peers on measures of multisensory integration (MSI) and to ascertain the degree to which differences in MSI are associated with the broad range of symptoms associated with ASD. Findings, however, have been highly variable across the studies carried out to date. The present work systematically reviews and quantitatively synthesizes the large literature on audiovisual MSI in individuals with ASD to evaluate the cumulative evidence for (a) group differences between individuals with ASD and TD peers, (b) correlations between MSI and autism symptoms in individuals with ASD and (c) study level factors that may moderate findings (i.e., explain differential effects) observed across studies. To identify eligible studies, a comprehensive search strategy was employed using the ProQuest search engine, PubMed database, forwards and backwards citation searches, direct author contact, and hand-searching of select conference proceedings. A significant between-group difference in MSI was evident in the literature, with individuals with ASD demonstrating worse audiovisual integration on average across studies compared to TD controls.

CONCLUSIONS: Trials of antidepressants may be driven mainly by commercial interests, focusing on prevalent diseases and everyday problems. No one can live a full life without experiencing several of the problems for which these drugs were tested. Antidepressants, sometimes called happy pills, could be seen as the modern version of Aldous Huxley's soma pill intended to keep everyone happy in the "Brave New World".

The objective is to present elements, needed to develop parent management training program to reduce behavioral problems in preschool children with autism spectrum disorder. At first, all parent management training programs for reducing behavioral problems of preschool children were collected. Subsequently, all programs were reviewed from the perspective of having a systematic review or meta-analysis, confirming the effectiveness of this program at preschool age. After that, interviews with experts and parents were conducted to identify effective elements on development of this program. In the next step, a set of component...

AbstractA number of clinical trials of cell therapies for autism spectrum disorder have been conducted, and some have published their outcomes. This review considers the data that have emerged from this small set of published trials, evaluates their success, and proposes further steps that could be taken if this field of endeavour is to be pursued further. A number of reservations arise from this tranche of studies, specifically the absence of identified therapeutic targets, and deficiencies in the therapeutic approach that is being employed. If this therapeutic direction is to be pursued further, then additional pre-clini...

Conclusions: Modifiable determinants of the negative attitude toward vaccinations are caused mainly by the lack of knowledge. These obstacles in vaccinations can be overcome by improving health education in terms of the vaccination program.
