Arizona State University wants participants - Brain Aging

Post Reply New Topic

Studies from one ASU lab seek to better understand how neurological conditions, such as autism, affect how the brain ages, and there are meaningful ways to participate for anyone who is interested.

Founded in 2016 by associate professor B. Blair Braden, the Autism and Brain Aging lab uses neurology to develop support for adults with autism. The lab is in need of neurotypical adults, or adults who are not autistic, to use as research controls for their important work.

Braden explained that this lab is filling an important niche in neurological research, because current studies into autistic adults have been limited.

"I think everyone deserves to have an expectation of what aging is going to be like. And we have that kind of general expectation for the typical population … But how aging will affect autistic adults has been just kind of a real question mark for a lot of years," Braden said.

While this is an under-researched area, there is still some research that suggests autism has serious comorbidities correlated with aging.

"Last year, a paper was published based on national Medicaid records that showed indeed, autistic adults are more likely to be diagnosed with an early onset Alzheimer's disease or related dementia. It's 2.6 times more likely if you have autism," said Braden.

At the lab, one form of research is program development for adults with autism, including Strengthening Skills, a behavioral intervention program.

"Before the pandemic, we did classes in person, and we did brain imaging before and after participants went through these mindfulness classes, and we saw all kinds of improvements in comorbid symptoms like depression and anxiety," Braden said.

"When the pandemic happened, we started working with app companies so we could work remotely with participants, and we just had a paper accepted that shows a mindfulness app is also effective in reducing depression in autistic adults," said Braden.

The classes and the app are designed to give autistic people support to reduce the symptoms of comorbidities, especially those that occur more often in adults.

The biggest project at the lab is a longitudinal study of the neurological differences in aging neurotypical adults and adults with autism.

"There is a cohort of about 120 adults that we follow every two years," Braden said. "We do a big cognitive assessment and we ask them all kinds of questions about their symptoms. And then we do brain imaging to get different structural and functional pictures of the brain."

The longitudinal study is also how the lab connects to autism research outside of ASU, through partnerships with the Southwest Autism Research and Resource Center (SARRC) and the Barrow Neurological Institute (BNI).

"SARRC has been traditionally one of our partners for recruiting autistic adults to participate in our study. But then most recently, (there was) the clinical trial in partnership with them," Braden said.

Nicole Matthews, director of research at SARRC, explained that the Autism and Brain Aging Lab also uses SARRC's clinical resources.

"We conduct intake assessments for the majority of Dr. Braden's projects. This means that a member of our team completes the Autism Diagnostic Observation Schedule (ADOS-2)," Matthews said.

SARRC and the Autism and Brain Aging Lab will continue their partnership for future projects.
