Podcast: The Different Flavors of Early Intervention

You may have heard terms in early intervention like “NDBI” or “Early Start Denver Model” and wondered if there was a difference in efficacy behind all these flavors of toddler interventions. On this week’s podcast, we speak to Dr. Giacomo Vivanti from @DrexelAutism, who combined data from 4 of these interventions across 700 children to see if they found similar or different effects of each protocol. This group of scientists also examined these interventions on the development of spoken language. The results reinforced: 1. the earlier the better when it comes to early intervention, 2. duration of the intervention matters, and 3. focusing on imitation may be a key to helping toddlers talk.

Two pediatricians, a child neurologist and a child psychiatrist walk into the ASF weekly science podcast to discuss the safety, efficacy and appropriateness of leucovorin, the drug that the HHS is fast tracking through the FDA approval process. Does it work? Is it safe? What should I do or know when I talk to my doctor?

Here is a link to the statement by the Society of Developmental and Behavioral Pediatrics: https://sdbp.org/sdbp-statements-regarding-leucovorin-tylenol-and-autism/

Here are the four studies mentioned:

This week the @WSJ reported that the upcoming MAHA report will include acetaminophen (also known as Tylenol in the United States, although it is used all over the world) use during pregnancy as a cause of autism. Acetaminophen is used in about 7.5 % of pregnant women. This is one of many environmental exposures that had previously been investigated in association with an autism diagnosis, but then disproven following rigorous and large scale studies with the right design. For example, is it acetaminophen or fever during pregnancy? Is it acetaminophen or some sort of underlying genetic susceptibility? This week’s ASF podcast episode explores the association and what pregnant women should know.

This year’s International Society of Autism Research Meeting was filled with great presentations about causes, diagnosis, interventions, mechanisms, supports, understanding sex differences and different populations of those with autism. But not everyone could fly to Seattle to attend. This week’s podcast episode provides a short summary of just some of the science presented. Michael Lombardo provided a keynote that included data from his research included on this podcast: https://blubrry.com/asfpodcast/137452290/factors-that-influence-heterogeity-and-how/

There is a cell in the brain called the microglia which has been traditionally overlooked as a target for therapies. New research supported by ASF and @FraxAresearch suggests that altering the function of microglia in the brain may help support the development of healthy and functional connections in the brain that may be impaired in autism, making the microglia a prime candidate for research. In this podcast episode, Drs. Marine Krzisch from @UniversityofLeeds and Dr. Mike Tranfaglia at @FraxAResearch describe the approach and how it can be developed to create specific therapies, that when combined with behavioral interventions, can drastically alter someone’s abilities. Dr. Krzisch is also interviewing families about how the findings will be explained when they are ready, what is important to them and what should research emphasize in the future. Participants will be compensated, just email her: M.Krzisch@leeds.ac.uk

Today’s #ASFpodcast explains the potential and the unknowns behind folate, known as leucovorin when prescribe, for treating autism. CBSNews reported on a “miraculous” study using leucovorin that will need further research before it lives up to the type. However, it is an example of how different biological markers may direct what treatments work best in what people, and possibly an example of precision medicine in ASD. Second, more of the mystery of the male/female diagnosis difference in ASD. How do genetics affect liability in males and females? It’s been well established females have more of a certain type of genetic variation, but females are less likely to be diagnosis. New results show that the liability for autism is the same in males and females (both are just as likely to receive a diagnosis based on their genetics), however these two sexes may have a different threshold for an autism diagnosis. Females may need more of these mutations to receive an autism diagnosis. Read more below:

Two therapies that are meant to alter brainwave activity, called Transcranial Magnetic Stimulation and Transcranial Direct Current Stimulation are receiving a lot of attention for potential efficacy in treating autism. They are non-invasive, which means treatment is provided on the scalp. While results vary, the overall evidence does not support these two interventions in helping to treat core autism features. However, as TMS is approved for depression and OCD, people should ask their doctors about these potential treatments if they suffer from these conditions.

Objectives: Individuals with neurodevelopmental disorders (NDDs), including autism spectrum disorder (ASD), often experience a higher prevalence of gastrointestinal (GI) symptoms but have complex medical and behavioral comorbidities that make diagnosis and treatment difficult. A multi-stakeholder conference was convened to (a) determine patient and family experiences related to GI symptoms in NDDs, (b) review the clinicians’ and researchers’ perspectives, and (c) determine actionable steps for future research.

Methods: The Consortium for Autism, Neurodevelopmental Disorders and Digestive Diseases (CANDID; www.candidgi.com) virtually over 2 days in 2022 and consisted of four key activities: (1) an electronic family survey to assess underlying NDDs and GI symptoms, (2) a session focused on family perspectives, (3) review current clinical care and research, and (4) discussion to identify key next steps. Survey results were obtained electronically via the REDCap platform, and descriptive statistics were generated. The sessions were recorded, and themes were identified.

Results: The pre-conference survey ran for ~2 months and 739 families provided responses, with 634 completing all items. 83% had a child with an NDD under age 18, and most patients were White (85%) and non-Hispanic (87%). Constipation (80%), GI reflux disease (51%), and bloating (49%) were the most frequently reported symptoms. Families gave unstructured feedback that the measures used in the surveys were often difficult to answer for patients with NDDs or who were nonspeaking. Family and clinical/scientific sessions identified several common themes, including (1) the need for less invasive diagnostic modalities, (2) the need to validate or adapt existing diagnostic measures (e.g., the Rome IV criteria) and outcome assessments, and (3) the need for enhanced attention to parent and caregiver input in treatment plans.

Conclusions: Those providing care to children with NDDs, especially those with communication and cognitive challenges, should be aware of the differing needs in this community and consider family perspectives in managing, treating, and measuring GI issues. Future research should focus on adapting or creating diagnostic and research measures for those with NDDs, developing new diagnostic methods to account for diversity in neurodevelopment and communication, and improving methods for family and caregiver engagement in the care of GI disorders.

The Program for the Education and Enrichment of Relational Skills (PEERS®) is an evidence-based intervention developed for autistic individuals to support social communication, peer interactions, independence, and interpersonal relationships. Despite a demonstrated effectiveness for young autistic individuals in the US and several other countries, PEERS has yet to be modified to support the needs of autistic adults across the lifespan. The present study describes how our team sought autistic voices to adapt PEERS for adults of any age. Specifically, we aimed to address the needs of middle-aged and older adults and adapt the curriculum to be more neurodiversity-affirming. Between two cohorts that completed the program consecutively, we evaluated the acceptability of the adapted PEERS program and made refinements based on feedback from autistic participants and their study partners. Results indicated that Cohort 2 reported higher satisfaction with the PEERS components and overall program than Cohort 1, suggesting effective refinement. We present a framework of adaptations that more specifically address the needs of middle-aged and older adults in a neurodiverse-affirming way compared to previous iterations. Our approach to implementing an adapted PEERS curriculum across the adult lifespan may serve as a model for improved clinical care and cultivate the acceptance of neurodiversity in the interpersonal domains of autistic adults’ lives.

During sleep, your brain is still active. It is turning all those things you learned during the day into long term memories through connections between the thalamus, hippocampus and frontal cortex. What happens in Profound Autism? How does the brain work during sleep and how will this knowledge lead to better sleep in people? Are there interventions already underway that are being tested that target sleep brainwaves? It can be hard to measure sleep, so in Part 2 of the Profound Autism Series, Dr. Dimitrios Mylonas from Harvard talks about his study to use portable home brain activity monitors that have been adapted for use in Profound Autism and an intervention based on this brain activity is being tested in other disorders. His study is now enrolling and is all remote, if you are interested in participating please email him at: DMYLONAS@mgh.harvard.edu

While NDBIs are generally considered beneficial, they still face controversies – do they actually work and does that translate to an improved quality of life for the family? This week’s #ASF podcast interviews Molly Reilly and Jinwei Song of @UConn to dive into these issues, as well as the role of the caregiver in the intervention and how their influence affects the outcome.
