Abstract: 

While there is an increasing equality in terms of the likelihood that children from communities and families across the socioeconomic spectrum will be diagnosed with autism, a new study finds that such factors still influence the chance of an autism diagnosis, though to a much lesser extent than they did at the height of rising prevalence.

Children With Autistic Traits Remain Undiagnosed

Abstract: 

There has been a major increase in the incidence of autism over the last twenty years. While people have differing opinions as to why this is (environment, vaccines, mother's age, better diagnostic practice, more awareness etc.) there are still many children who have autistic traits that are never diagnosed clinically. Therefore, they do not receive the support they need through educational or health services.

The Autism Diagnostic Interview-Revised is a tool clinician’s use for the diagnosis of a child with an autism spectrum disorder (ASD). The diagnostic algorithms of the evaluative tool were altered to improve sensitivity and specificity compared to the previous algorithm.

No Autism Epidemic

Abstract: 

A study conducted in 1998 found that autism occurred in 0.05 per cent of Norwegian children. The figures from the "Barn i Bergen" project could therefore be interpreted to mean that the incidence of autism has risen dramatically. However, Ms Posserud thinks it is important to downplay the difference in results. Her conclusion is that the rise in ASD can be explained mainly by the use of more thorough mapping methods and, consequently, that we are not seeing the emergence of an autism epidemic

Abstract: 

For many years, behavioral testing and observation have been the only way to determine if a child is autistic, often causing distress and confusion for parents. However, now the application of the standard electroencephalogram (EEG) combined with borrowed math from chaos theory, may enable doctors to read brain wave patterns and identify levels of autism one to two years earlier with 80% accuracy.

Autism and Increased Paternal Age Related Changes in Global Levels of Gene Expression Regulation

This study, performed by researchers at the University of Pennsylvania, analyzed the level of gene expression in children with autism, compared with a control group. The researchers hypothesized that the variability in the pattern of the overall of gene expression levels would be associated with variability in hippocampal-dependent behaviors, which include short-term memory and spatial navigation. Additionally, the group tested whether increased paternal age was associated with variance of gene expression. A decrease in the variability of gene expression levels was associated with the diagnosis of autism and increased paternal age. The research team believes this change to be caused by the down-regulation of gene expression pathways involved in protein synthesis regulation in the blood of children with autism and children with older fathers. Thus, the researchers concluded that alterations at the gene level of gene expression regulation are related to autism and increased paternal age.

Abstract: 

A second child is three times more likely to be diagnosed with autism if they are born within twelve months of their siblings, compared to those born three or more years apart, researchers from the Lazarsfeld Center for the Social Sciences at Columbia University, New York revealed in the journal Pediatrics. The investigators gathered information on 660,000 second children born in California between 1992 to 2002.

Prevalence of Autism According to Maternal Immigrant Status and Ethnic Origin

This study examined the rates of autism according to maternal immigrant status and ethnic origins based on the vitamin D insufficiency hypothesis, which proposes that maternal vitamin D insufficiency during pregnancy could be associated with autism. The study provided further support to the association between maternal immigrant status and an increased risk of autism. In addition, although more complex, ethnic origin was shown to have an effect on the rates of autism; the study found that black ethnicity demonstrated a higher incidence of autism, particularly when considering autism associated with mental retardation. The results found in the study are consistent with the maternal vitamin D insufficiency hypothesis. To understand the effect of maternal vitamin D insufficiency during pregnancy on the development of the fetal brain, neurobiological studies are necessary.

Abstract: 

The International Center for Autism Research and Education (ICare4autism), a New York-based charity, announced plans to create the world's first Global Autism Center on Mt. Scopus in Israel, dedicated to catalyzing breakthrough innovation in autism research and treatment. In a ceremony at Jerusalem's City Hall hosted by Mayor Nir Barkat, ICare4autism's President Joshua Weinstein signed an agreement paving the way for ICare4autism to acquire the campus of Bezalel Academy of Art in 2013, and convert it into a center.
