Exploring the ADHD-Autism link


“That is an rising subject with nice promise,” says Jean Gehricke, an affiliate professor of pediatrics at UC Irvine and a licensed scientific psychologist with the Middle for Autism & Neurodevelopmental Problems. “We all know a bit in regards to the underlying causes of ADHD, and thru this, we might be able to enhance how we deal with autism.”

For the higher a part of the final decade, a rising physique of analysis has been revealing increasingly similarities between attention-deficit/hyperactivity dysfunction and autism.
Jean Gehricke, an affiliate professor of pediatrics at UC Irvine and a licensed scientific psychologist with the Middle for Autism & Neurodevelopmental Problems, is specializing in this hyperlink to raised perceive why folks with ADHD and autism could also be extra susceptible to substance abuse and, within the course of, to develop more practical behavioral therapies.
"That is an rising subject with nice promise," Gehricke says. "We all know a bit in regards to the underlying causes of ADHD, and thru this, we might be able to enhance how we deal with autism."
The Middle for Autism & Neurodevelopmental Problems - which gives evaluation, analysis, therapy, care coordination, household assist and training for youngsters, teenagers and younger adults with autism and different developmental issues - is one in every of only some within the area to ship a continuum of providers till age 22 and to conduct analysis aimed toward reworking the method to autism.
Gehricke, who teaches 25 college students in his lab, has experience within the evaluation and therapy of autism, ADHD and co-occurring issues corresponding to despair, nervousness and drug abuse.
He joined the middle in 2013. Earlier than that, he labored on the UCLA Neuropsychiatric Institute & Hospital, the UCI Transdisciplinary Tobacco Use Analysis Middle and the UCI Little one Improvement Middle, the place he additionally offered complete scientific assessments and cognitive behavioral remedy.
Gehricke is well-known for his scientific work on the underlying mechanisms of ADHD and drug abuse, having printed a variety of breakthrough articles exhibiting why people with ADHD are extra susceptible to smoke cigarettes or get hooked on different nicotine and tobacco merchandise.
He is taking this data and making use of it to autism. Whereas folks with ADHD and high-functioning autism share sure traits, corresponding to issue interacting with others and issues with emotional management, Gehricke is particularly keen on whether or not these points have comparable neurobiological underpinnings.
In a December 2014 examine, he and his colleagues recognized a genetic trait shared by these with ADHD and people with autism that sheds gentle on a few of the extra troubling behaviors related to the issues.
Gehricke explains that aggression and health-risk actions are pushed by distorted dopamine signaling within the mind and that the DRD4 gene is important in regulating this perform. The researchers discovered that one type of the gene - referred to as the 7R allele and linked to altered dopamine regulation - is overrepresented in each people with ADHD and people with autism. It is the genetic fingerprint of a lot of these conduct, Gehricke says.
"This examine gives a conceptual mannequin for dangerous behaviors, which we regularly see in our sufferers, and explores the potential of tailoring info to scale back them," he says. "Extra particularly, it factors to the necessity to use robust visible photos to induce behavioral modifications."
Gehricke is particularly centered on nicotine habit - which, he factors out, is one other shared ADHD-autism inclination. He believes that early behavioral intervention with autistic youngsters could possibly be a very efficient deterrent to smoking - the No. 1 preventable well being risk on this planet - and "vaping."
Gehricke says that the intervention ought to embody warning labels (corresponding to these used with nicotine and tobacco) depicting the adverse penalties of health-risk behaviors and presenting distinctive imagery visually stimulating sufficient to change the actions of youngsters and younger adults with ADHD and autism. Testing the effectiveness of this deterrent is the subsequent step Gehricke plans to take along with his 7R allele group.
"Analysis - such because the initiatives carried out by Jean - is without doubt one of the core pillars of our mission on the Middle for Autism & Neurodevelopmental Problems," says Catherine Brock, govt director. "By means of his efforts and the households that take part, we're higher capable of perceive the underlying mechanisms of autism spectrum issues and ADHD."
