Autism Teachers

Future research may allow therapists to know in advance which type of applied behavior analysis (ABA therapy) is most likely to work for any given child with autism.

This study of six children was designed to see if it is possible to predict which type of ABA therapy will work for which child with autism.

The authors were able to predict which children would respond to pivotal response training, but not which ones would respond to discrete trial training. The authors note that all children were first exposed to pivotal response training and then to discrete trial training and this may have influenced the results. Children who liked toys were more likely to respond to pivotal response training than children who did not like toys.

parents leaving their offices with an autism spectrum diagnosis for their child will have a clear plan of action for getting their child the help they need, where and when they need it.

Researchers will develop a better understanding of autistic subgroups, so that it will become possible to recommend appropriate treatments and therapies based on individuals' symptoms, challenges and strengths.

Less time, money, energy and angst will go into confrontation, and more time, money, energy and love will go into autism-related volunteerism, mentoring, program development, and other positive activities.

the study found, children who had received the MMR vaccine actually had a lower risk of autism than their unvaccinated peers. Nor was there any evidence of an increased autism risk with the measles-only vaccine.

Here are answers from a top expert, Dr. Susan Levy of the Children's Hospital of Philadelphia.

Dr. Levy says, while about 80% of autism is idiopathic (of unknown cause), there are at present many known causes of autism including FAS, rubella, Fragile X Syndrome, and more. In addition, according to a a report published in Pediatrics in 2009 entitled "Prevalence of parent-reported diagnosis of autism spectrum disorder among children in the US, 2007," as many as 40% of children who received an autism spectrum disorder at some point in their lives are no longer diagnosable on the autism spectrum.

“Having at our fingertips detailed information about when and where specific gene products are expressed in the brain brings new hope for understanding how this process can go awry in schizophrenia, autism and other brain disorders,” said NIMH Director Thomas R. Insel, M.D.

Among key findings in the prefrontal cortex:Individual genetic variations are profoundly linked to expression patterns. The most similarity across individuals is detected early in development and again as we approach the end of life.Different types of related genes are expressed during prenatal development, infancy, and childhood, so that each of these stages shows a relatively distinct transcriptional identity. Three-fourths of genes reverse their direction of expression after birth, with most switching from on to off.Expression of genes involved in cell division declines prenatally and in infancy, while expression of genes important for making synapses, or connections between brain cells, increases. In contrast, genes required for neuronal projections decline after birth – likely as unused connections are pruned.By the time we reach our 50s, overall gene expression begins to increase, mirroring the sharp reversal of fetal expression changes that occur in infancy.Genetic variation in the genome as a whole showed no effect on variation in the transcriptome as a whole, despite how genetically distant individuals might be. Hence, human cortexes have a consistent molecular architecture, despite our diversity.

Among key findings:Over 90 percent of the genes expressed in the brain are differentially regulated across brain regions and/or over developmental time periods. There are also widespread differences across region and time periods in the combination of a gene’s exons that are expressed.Timing and location are far more influential in regulating gene expression than gender, ethnicity or individual variation.Among 29 modules of co-expressed genes identified, each had distinct expression patterns and represented different biological processes. Genetic variation in some of the most well-connected genes in these modules, called hub genes, has previously been linked to mental disorders, including schizophrenia and depression.Telltale similarities in expression profiles with genes previously implicated in schizophrenia and autism are providing leads to discovery of other genes potentially involved in those disorders.Sex differences in the risk for certain mental disorders may be traceable to transcriptional mechanisms. More than three-fourths of 159 genes expressed differentially between the sexes were male-biased, most prenatally. Some genes found to have such sex-biased expression had previously been associated with disorders that affect males more than females, such as schizophrenia, Williams syndrome, and autism.
