New ADHD and Neurodevelopmental Research for School Psychologists

Students with ADHD, autism, learning differences, and other neurodevelopmental disorders are often asked to succeed in systems that were not designed with them in mind. This week’s research offers a useful reminder: support is not just about diagnosis. It is about communication, instruction, biology, treatment, and the everyday settings where students live and learn.

Three new studies point to a bigger shift in the field. We are learning more about how to teach students complex skills, how ADHD may manifest in the body and brain, and how evidence-based treatment works beyond the clean lines of a research trial.

Helping Students With Neurodevelopmental Disorders Talk Like Scientists

The first study, published in the Canadian Journal of School Psychology, looked at a video-enhanced intervention for students with neurodevelopmental disorders. The goal was not simply to teach science facts. It was to help students use scientific language, explain their thinking, and participate more fully in science learning.

That matters. For many students with neurodevelopmental disorders, the challenge is not just knowing the answer. It is explaining observations, making claims, using evidence, and joining classroom conversations. These are communication, academic, and confidence-building skills all at once.

The study used a single-case design with two students and found meaningful gains in their use of scientific language and practices. The sample was small, so this is not a sweeping conclusion. But it is a promising example of how targeted, multimedia-supported instruction can help students access more than content. It can help them participate.

For school psychologists and educators, the takeaway is practical: when we think about STEM access, we should not only ask whether students understand the material. We should also ask whether they have the communication tools to show what they know.

A Possible Biological Clue in ADHD

Another study, published in the Journal of Attention Disorders, explored a potential biological marker connected to ADHD: Netrin-1.

Netrin-1 is involved in the development of neural connections. In this study, children with ADHD had higher serum levels of Netrin-1 than typically developing peers. The researchers also found that Netrin-1 levels were linked with parent-reported hyperactivity and executive functioning difficulties.

This does not mean we are close to a simple blood test for ADHD. We are not. ADHD remains a clinical diagnosis based on behavior, development, impairment, and context. But studies like this help deepen the science behind what many families and educators see every day: ADHD is not a motivation problem or a character flaw. It reflects differences in brain development, regulation, and functioning.

For parents, this kind of research can be validating. For school professionals, it is a reminder to keep pushing back against explanations that frame ADHD as laziness, defiance, or poor parenting.

Does CBT for ADHD Work in the Real World?

The third study looked at cognitive behavioral therapy for adolescents with ADHD in routine outpatient care. This is important because treatments often look strongest in tightly controlled research trials. Real-world settings are messier. Families miss appointments. Symptoms overlap. Medication use varies. Clinicians adapt.

In a large sample of 420 adolescents, CBT was associated with meaningful reductions in ADHD symptoms, whether or not adolescents were also taking medication. The greatest improvements were seen among teens who started treatment with clinically significant symptoms.

That is good news. It suggests that CBT can still help when delivered in ordinary clinical settings, not just in ideal research conditions.

For school psychologists, this finding also supports closer collaboration with community providers. Teens with ADHD often need support across settings: school, home, therapy, and sometimes medication management. CBT skills such as planning, organization, emotion regulation, and problem-solving can become more powerful when schools understand and reinforce them.

What This Means for Schools and Families

Taken together, these studies point toward a fuller picture of support for neurodiverse students.

Students need instruction that helps them communicate and participate. Families need explanations that move beyond blame. Clinicians and schools need treatments that work in real life, not just in journal articles.

The common thread is this: neurodevelopmental support should be practical, humane, and connected across settings.

For school psychologists, this means continuing to bridge assessment, intervention, consultation, and family support. For parents, it means knowing that research is moving toward a more complete understanding of children’s needs. And for schools, it means recognizing that good support is not one program, one accommodation, or one diagnosis. It is a coordinated approach that helps students function, learn, and belong.
