Yeah, another study about autistic poop
Published July 2, 2019 in ASF PodcastThis week’s podcast includes a summary of the new study, this time in an animal model, looking at microbiome transplantation. Because this was more of an experimental model, the researchers could be more rigorous in their design and look at things like behavior, brain activity, and specific biological pathways. While a mouse does not have […]

Do the rules apply in school?
Published July 2, 2019 in ASF PodcastThis week is focused on what happens in schools, including classification, service receipt and new interventions. How an educational classification translates to a clinical diagnosis, how and what factors are important in receiving services, what teachers think about repetitive behaviors and finally, a new intervention that can be delivered by therapists in school or mental […]

A longitudinal study of parent-reported sensory responsiveness in toddlers at-risk for autism
Published June 26, 2019 in The Journal of Child Psychology and PsychiatryBACKGROUND: Atypical sensory responsivity and sensory interests are now included in the DSM 5 diagnostic criteria for autism spectrum disorder (ASD) under the broad domain of restricted and repetitive behavior (RRB). However, relatively little is known about the emergence of sensory-related features and their relation to conventionally defined RRB in the first years of life. […]

New Behavioral Test Uncovers Autism Mouse’s Stubbornness
Published October 2, 2013 in Simons Foundation Autism Research InstituteResearchers have developed a new test that reveals complex repetitive behaviors in BTBR mice, a mouse strain with features resembling those of autism, according to a study published in the Journal of Neuroscience Methods. Repetitive behavior is common in autism, and usually comes in two forms: repetitive actions, such as hand flapping or rocking, and higher-order symptoms, such as an insistence on sameness, or restricted interests. This second form is difficult to produce in mice, but these researchers believe they have been able to do it.

Two Studies Isolate Specific Brain Circuits That Underlie Compulsive Behaviors Seen in Individuals with OCD and Autism
Published June 7, 2013 in ScienceTwo studies successfully attempted to shut down and trigger compulsive behaviors in mice by using light to target certain brain circuits. These studies helped isolate the obsessive brain circuits believed to underlie compulsive behaviors in individuals with OCD and autism. 1) http://www.ncbi.nlm.nih.gov/pubmed/237449502) http://www.ncbi.nlm.nih.gov/pubmed/23744948

Elevated Repetitive Behaviors are Associated with Lower Diurnal Salivary Cortisol Levels in Autism Spectrum Disorder
Published March 1, 2013 in Biological PsychiatryThis pilot study examined the relationship between repetitive behaviors (RBs) and cortisol, a hormone that is released in response to stress, in individuals with ASD. Multiple salivary cortisol samples were taken over three days for 21 children with ASD with high and low levels of RBs. Children in both groups showed the same pattern of cortisol change throughout the day, but the overall cortisol levels in the high RB group were significantly lower, suggesting RBs may work to soothe and decrease stress.

Frequency and Pattern of Documented Diagnostic Features and the Age of Autism Identification
Published February 6, 2013 in Journal of the American Academy of Child & Pediatric PsychiatryThe age at which a child with autism is diagnosed is related to the particular suite of behavioral symptoms he or she exhibits, according to this study led by an ASF Grantee. Certain diagnostic features, including poor nonverbal communication and repetitive behaviors, were associated with earlier identification of an autism spectrum disorder. Displaying more behavioral features was also associated with earlier diagnosis.For more information about this study, read the guest blog from the lead author here: http://autismsciencefoundation.wordpress.com/2013/04/09/identifying-asd-in-community-settings/

Antioxidants For Autism
Published June 1, 2012 in Biological PsychiatryA specific antioxidant supplement containing N-Acetylcysteine, or NAC may be an effective therapy for some features of autism, according to a pilot trial from the Stanford University School of Medicine and Lucile Packard Children’s Hospital that involved 31 children with the disorder.

Six Developmental Trajectories Characterize Children With Autism
Published May 1, 2012 in Pediatrics“OBJECTIVE: The goal of this study was to describe the typical longitudinal developmental trajectories of social and communication functioning in children with autism and to determine the correlates of these trajectories.RESULTS: Six typical patterns of social, communication, and repetitive behavior functioning were identified. These trajectories displayed significant heterogeneity in developmental pathways, and children whose symptoms were least severe at first diagnosis tended to improve more rapidly than those severely affected. “

Agent Reduces Autism-like Behaviors in Mice
Published April 26, 2012 in NIMHNational Institutes of Health researchers have reversed behaviors in mice resembling two of the three core symptoms of autism spectrum disorders (ASD). An experimental compound, called GRN-529, increased social interactions and lessened repetitive self-grooming behavior in a strain of mice that normally display such autism-like behaviors, the researchers say.

Repetitive behaviors in adults with Autism Spectrum disorders significantly lessen with antidepressant treatment
Published December 5, 2011 in MedicalXpressRestricted, repetitive behavior, such as compulsive arranging and rigid adherence to routines, is a defining symptom of autism spectrum disorders. A 12-week study showed that the antidepressant fluoxetine produced a greater decrease in repetitive behaviors and more overall improvement than placebo in adults with autism spectrum disorders.

Shank3 Mutant Mice Display Autistic-like Behaviors and Striatal Dysfunction
Published March 1, 2011Currently, the neurological basis of autism spectrum disorders (ASDs) is poorly understood. “Shank3 is a postsynaptic protein, whose disruption at the genetic level is thought to be responsible for the development of 22q13 deletion syndrome (Phelan-McDermid syndrome) and other non-syndromic ASDs”. In this study, mice with the Shank3 deletion were seen to exhibit “self-injurious repetitive […]
