Neurodivergence — being autistic, having ADHD, or both — isn't a disorder to be cured but a different way a brain is wired to perceive, process, and respond to the world. For many teens, the hard part isn't their neurology itself; it's living and learning in environments built for a different kind of brain, often while being asked to hide the very ways they cope. Understanding how neurodivergence actually shows up in adolescence is the first step toward support that helps rather than harms.
One reason so many neurodivergent teens go unidentified for years is that the familiar picture is narrow. Autism and ADHD frequently present differently than the stereotypes suggest — especially in girls, who often mask their differences so well that their genuine struggles get overlooked until anxiety, exhaustion, or burnout finally surface. Anxiety, in fact, is one of the most common companions of autism, and the overlap between the two can be hard to untangle without someone who understands both. Concepts like PDA (pathological demand avoidance) describe profiles that conventional approaches routinely misread as defiance.
The pages in this cluster look more closely at ADHD, autism, PDA, autism in girls, and the autism–anxiety overlap — with an emphasis on recognizing these profiles accurately and supporting teens as who they are. Good support builds skills, eases real distress, and adapts the environment, rather than trying to make a young person appear "normal." Nothing here is a substitute for a thorough evaluation; if your teen is struggling, a clinician experienced with how neurodivergence presents across different kids can help you find clarity and the right kind of help.
