Research by Topic: Cognition
A number of studies of parent-mediated interventions in autism spectrum disorder have been published in the last 15 years. We reviewed 19 randomized clinical trials of parent-mediated interventions for children with autism spectrum disorder between the ages of 1 and 6 years and conducted a meta-analysis on their efficacy. Meta-analysis outcomes were autism spectrum disorder symptom severity, […]
Group Cognitive Behavior Therapy for Children with High-Functioning Autism Spectrum Disorders and Anxiety: A Randomized TrialPublished April 8, 2015 in J Child Psychol Psychiatry
Fifty children with high-functioning Autism Spectrum Disorder (ASD) and anxiety were randomized to group Cognitive Behavioral Theory (CBT) or treatment-as-usual (TAU) for 12 weeks.
Nelson Freimer and colleagues at UCLA studied a population in an isolated area of Finland where Schizophrenia is more common than in the average Finnish population. In this small group, it was discovered that the presence of a deletion on part of chromosome 22 was much more prevalent than in the rest of the population. This deleted region normally contains an enzyme, TOP3B. This lack of TOP3B is also linked to disruptions that can lead to Fragile X Syndrome, showing there may be a biological link between Fragile X and Schizophrenia. An article about this study can be found here:http://www.newscientist.com/article/dn23995-genetic-discovery-links-autism-and-schizophrenia.html#.UgJvzZJJNf2
During a brain study, researchers found that individuals with autism have specific areas of hyperconnectivity in the brain. This supports the theory that unique autistic behaviors stem from differences in brain wiring.
This Stanford study identifies an underconnectivity between the voice-selective cortex and the reward centers in the brain. This could suggest why children with autism have trouble grasping the social and emotional aspects of human speech.
Two Studies Isolate Specific Brain Circuits That Underlie Compulsive Behaviors Seen in Individuals with OCD and AutismPublished June 7, 2013 in Science
Two 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
Brief Report: Is Cognitive Rehabilitation Needed in Verbal Adults with Autism? Insights from Initial Enrollment in a Trial of Cognitive Enhancement TherapyPublished February 5, 2013 in Journal of Autism and Developmental Disorders
Early results from this pilot trial of cognitive enhancement therapy (CET) indicate that despite above-average intelligence, verbal adults with ASD can have significantly impaired neurocognition and social cognition. The authors suggest CET, which is designed to remediate both social and non-social deficits through computer-based neurocognitive training, could be useful for cognitive rehabilitation in this population.
