A recent study published in Molecular Psychiatry has found that autism and ADHD may share a common biological basis. Researchers used resting-state functional MRI and spatial transcriptomics to analyze brain connectivity and gene expression in 166 children with autism or ADHD.
What the Study Found
The study revealed that children with more severe autism symptoms showed stronger connections between key brain networks, including the frontoparietal and default-mode systems. These networks play important roles in social thinking and executive function.

Implications for Diagnosis and Treatment
The findings suggest that focusing on specific symptom dimensions and their biological correlates may lead to more precise recognition and treatment approaches tailored to individual neural profiles. This approach supports a growing movement in psychiatry toward dimensional, transdiagnostic, and data-driven models of mental health.
The study’s findings provide a more nuanced understanding of neurodevelopmental conditions and highlight the importance of considering the complexity of brain connectivity and gene expression in the diagnosis and treatment of autism and ADHD.

Shared Genetic Mechanisms
The researchers also found that the brain connectivity patterns aligned with regions of gene expression linked to neural development, which have previously been associated with both autism and ADHD. This overlap suggests that similar biological processes may contribute to traits seen across both conditions.

Is your child struggling in school?
Get your free personalized learning roadmap
You describe what you see at home. We turn it into a plan you start this week.
- Answer 5 short questionnaires about what you already notice, 30–45 minutes at your own kitchen table
- Your child sits no test and gets no score: nothing to schedule, nothing for them to dread
- You do the answering, the AI does the writing, and a person reviews it before it reaches you
- Access all 40+ courses instantly: reading, math, focus, processing and more, with new ones added regularly
Why we use AI, plainly: it writes from a knowledge base our team maintains and audits. We work through it line by line and pull anything the evidence stops supporting. The roadmap you get on Tuesday reflects what we corrected on Monday, and a human still reads it before you do.
Your school district must evaluate your child free of charge if you ask in writing, whatever your income and whatever the outcome (US, 34 CFR 300.111 and 300.301(b)). That route takes time and answers a different question than you do. This one starts today, from what you already know.
Your answers stay yours. We do not sell your personal information, and we do not hand identifiable assessment data to outside AI companies to train their models.
A screener is a starting point, not a diagnosis. If your child might need formal accommodations (an IEP or 504 plan), or you suspect a vision, hearing or medical cause, pursue a professional evaluation too. That is the only route to those supports.
