Research highlights key challenges and opportunities in transitioning autistic individuals into adulthood

Adults with ADHD are at increased risk for developing dementia
The Autism Transitions Research Project has released new findings that underscore critical challenges and opportunities in transitioning autistic youth into adulthood.

The Autism Transitions Research Project, funded by the Health Resources and Services Administration and led by Drexel University’s A.J. Drexel Autism Institute, has released new findings that highlight critical challenges and opportunities in transitioning autistic youth into adulthood. With approximately 1.2 million autistic individuals expected to reach adulthood in the coming decade, these insights are crucial for shaping future research and services.

The study titled “Challenges and Opportunities in Transitioning Autistic Individuals into Adulthood” was led by Anne M. Roux, a research scientist and director at the Policy Impact Project in the Autism Institute’s Policy and Analytics Center, along with a multidisciplinary team.

The study identifies critical barriers that hinder successful transitions for autistic individuals, including delays in diagnosis and access to services, long waitlists, and an over-reliance on care partners to provide daily support and navigate complex service systems. Funded through the Autism Transitions Research Project grant under principal investigator Lindsay Shea DrPH, the study also emphasizes the importance of cultural considerations and responsiveness, as well as the inclusion of autistic individuals in the development of transition services.

Key findings include:

  • Significant delays in diagnosis and access to transition services exacerbate challenges for autistic youth and their families.
  • There is a critical need for peer navigation support and tailored services for marginalized groups, such as those with intersecting identities.
  • Disparities in service availability across geographic locations.
  • Difficulty accessing essential benefits programs, like Supplemental Security Income, and need to revise benefits programs that reinforce poverty.

Participants in nine focus groups—which included autistic young adults, care partners, and professionals—emphasized the need for research focusing on the efficacy of transition services, the impact of system performance on outcomes, and the need for transformation in service ecosystems.

“This research reflects the perspectives of those most impacted by transition challenges and offers a pathway to more inclusive and effective solutions,” said Roux. “We must prioritize autistic perspectives and account for cultural differences when designing transition services and supports.”

The study’s recommendations include developing population-level research to assess system performance, improving service delivery for marginalized groups, and transforming the complexity of service ecosystems to better support successful transitions for all autistic youth across differing life experiences.

Increased autism symptoms linked to Y chromosome

Research offers new explanation for greater ASD risk among males
Research offers a new explanation for a greater possibility of autism among males.

 Increased probability for autism appears to be linked to the Y chromosome, a Geisinger study found, offering a new explanation for the greater prevalence of autism in males. T

Autism is a neurodevelopmental condition characterized by impaired social interaction and communication and restricted and repetitive patterns of behaviour, interests and activities. AAutism is nearly four times more prevalent among males than females, but the reason for this disparity is not well understood.

One common hypothesis involves the difference in sex chromosomes between males and females—typical females have two X chromosomes, while typical males have one X and one Y chromosome.

“A leading theory in the field is that protective factors of the X chromosome lower autism in females,” said Matthew Oetjens, Ph.D., assistant professor at Geisinger’s Autism & Developmental Medicine Institute.

The Geisinger research team, led by Dr Oetjens and Alexander Berry, PhD, staff scientist, sought to determine the effects of the X and Y chromosomes on autism risk by examining ASD diagnoses in people with an abnormal number of X or Y chromosomes, a genetic condition known as sex chromosome aneuploidy.

The team analyzed genetic and autism diagnosis data on 177,416 patients enrolled in the Simons Foundation Powering Autism Research (SPARK) study and Geisinger’s MyCode Community Health Initiative. They found that individuals with an additional X chromosome had no change in ASD risk, but that those with an extra Y chromosome were twice as likely to have an ASD diagnosis. This suggests a risk factor associated with the Y chromosome instead of a protective factor associated with the X chromosome.

“While these may seem like two sides of the same coin, our results encourage us to look for autism risk factors on the Y chromosome instead of limiting our search to protective factors on the X chromosome,” Dr. Berry said. “However, further research is needed to identify the specific risk factor associated with the Y chromosome.”

Echoes in the brain: Why today’s workout could fuel next week’s bright idea

The everyday effects of sleep, exercise, heart rate and mood — both good and bad — could linger in our brains for over two weeks, according to a pioneering study
According to a pioneering study, the everyday effects of sleep, exercise, heart rate and mood — both good and bad — could linger in our brains for over two weeks.

In a rare, longitudinal study, researchers from Aalto University and the University of Oulu tracked one person’s brain and behavioural activity for five months using brain scans and data from wearable devices and smartphones. 

‘We wanted to go beyond isolated events,’ says research leader Ana Triana. ‘Our environment and experiences constantly shape our behaviour and mental states. Yet, we know little about the response of brain functional connectivity to environmental, physiological, and behavioural changes on different timescales, from days to months.’ 

The study discovered that our brains don’t react to daily life in short, isolated bursts. Instead, brain activity changes in response to sleep patterns, physical activity, mood, and respiration rate over several days. This implies that even a workout or a restless night from last week could still impact your brain — and consequently your attention, thinking, and memory — well into next week.

The research also revealed a strong link between heart rate variability, which measures the heart’s adaptability, and brain connectivity, particularly during rest. This suggests that activities that affect our body’s relaxation response, such as stress management techniques, could influence the wiring of our brains even when we are not actively focusing on a task. The study also found that physical activity has a positive impact on the interaction between different brain regions, potentially affecting memory and cognitive flexibility. Furthermore, even small changes in mood and heart rate had lasting effects for up to fifteen days.

The study goes beyond a snapshot.

The research is unusual because few brain studies involve detailed monitoring over days and weeks. ‘The use of wearable technology was crucial’, says Triana. ‘Brain scans are useful tools, but a snapshot of someone lying still for half an hour can only show so much. Our brains do not work in isolation.’

Triana was the subject of the research, being monitored as she went about her daily life. Her dual role as both lead author and study participant added complexity but also provided firsthand insights into how to best maintain research integrity during several months of personalized data collection.

‘At the beginning, it was exciting and a bit stressful. Then, routine settles in, and you forget,’ says Triana. Qualitative data from mood surveys complemented data from the devices and twice-weekly brain scans. 

The researchers identified two distinct response patterns: a short-term wave lasting under seven days and a long-term wave of up to fifteen days. The short-term wave reflects rapid adaptations, such as how the focus is impacted by poor sleep, but it recovers quickly. The long wave suggests more gradual, lasting effects, particularly in areas tied to attention and memory.

Single-subject studies offer opportunities for improving mental health care.

The researchers hope their innovative approach will inspire future studies that combine brain data with everyday life to help personalise mental health treatment. 

‘We must bring data from daily life into the lab to see the full picture of how our habits shape the brain, but surveys can be tiring and inaccurate,’ says study co-author, neuroscientist and physician Dr Nick Hayward. ‘Combining concurrent physiology with repeated brain scans in one person is crucial. Our approach gives context to neuroscience and delivers very fine detail to our understanding of the brain.’ 

The study is also a proof-of-concept for patient research. Tracking brain changes in real-time could help detect neurological disorders early, especially mental health conditions where subtle signs might be missed.

“Linking brain activity with physiological and environmental data could revolutionize personalized healthcare, opening doors for earlier interventions and better outcomes,” says Triana.

Innovative nanoparticle therapy targets fat absorption to combat obesity

Researchers have unveiled a novel approach to tackle obesity by targeting fat absorption in the small intestine.
Researchers have unveiled a novel approach to tackle obesity by targeting fat absorption in the small intestine.

Researchers have introduced a new method to address obesity by targeting fat absorption in the small intestine. The advanced nanoparticle system, designed to transport therapeutic molecules directly to the digestive tract, has displayed significant potential in preventing diet-induced obesity.

Presented today at UEG Week 2024, the study focuses on an enzyme called Sterol O-acyltransferase 2 (SOAT2), which plays a critical role in fat absorption in the small intestine.3,4 By inhibiting this enzyme, the study offers a promising therapeutic approach to reducing fat absorption and potentially preventing obesity.

Despite extensive research into fat metabolism, effective inhibitors of intestinal fatty acid uptake have remained elusive until now. Lead researcher Dr. Wentao Shao explained, “For years, researchers have studied fat metabolism, but finding an effective way to block fat absorption has been difficult. While most strategies focus on reducing dietary fat intake, our approach targets the body’s fat absorption process directly.”

The research team has developed an innovative delivery system using nanoparticles. These are tiny capsules made from a polymer core and coated in a protective shell. The system is designed to efficiently carry small interfering RNAs (siRNAs) to the small intestine. Once there, the siRNAs can reduce SOAT2 expression, which in turn inhibits fat absorption. In mouse models, the animals treated with nanoparticle therapy absorbed less fat and avoided obesity, even when on a high-fat diet.

“This oral treatment offers several advantages”, said Dr Shao. “It’s non-invasive, has low toxicity, and it has high potential for better patient compliance compared to current obesity treatments, which are often invasive or difficult to maintain. This makes it a promising alternative.”

The study also uncovered the underlying mechanism by which SOAT2 regulates fat absorption. Inhibition of SOAT2 in the small intestine triggers the degradation of CD36, a protein responsible for transporting fat. This process involves both cellular stress and the recruitment of E3 ligase RNF5, an enzyme that enhances CD36 degradation.

Previous studies have shown that blocking hepatic SOAT2 leads to fat accumulation in the liver, 5,6  whereas this intestine-specific approach circumvents that risk, offering a safer and more focused treatment for obesity.
