For many years, autism was considered synonymous with intellectual disability. A new study shows that perception is inaccurate.
Diagnosing autism is an evolving science but a crucial first step to understanding the disorder.
In the new diagnostic manual for psychiatric disorders, Asperger syndrome will be folded into autism spectrum disorder. Francesca Happé, a member of the committee that made the recommendation, explains the rationale behind the decision.
Researchers have created a mouse carrying a deletion in SHANK3, an autism candidate gene, they reported yesterday in Nature. This is the second model of SHANK3 mutations but shows markedly more behavioral and brain defects compared with the first.
Toddlers with autism have typical — although delayed — language skills, but produce more growls, yells and, especially, squeals than do typically developing children, according to a study published in February in Autism Research.
Mutations in a gene that organizes synapses — the junctions between neurons — may increase the risk of autism, according to a study published in February in Autism Research. The study bolsters evidence linking a pathway involved in cell-to-cell communication to autism.
It’s too soon to call it a diagnostic test for autism, but an algorithm that detects patterns in brain waves shows promise as one component of a screening battery for the disorder, say researchers familiar with the work.
Genetic risk factors for specific language impairment and autism affect the timing of language learning in the general population, according to a study published in February in Genes, Brain and Behavior.
Children who walk on their toes are more likely to have autism than other forms of developmental delay, according to a study published in January in The Journal of Child Neurology.
