Imagine a young person walking out of my office with a new diagnosis of ADHD and feeling relieved. There’s finally a name for years of missed deadlines and unfinished paperwork.
A few weeks later, they use the name to break up an argument at home over an unmade bed and a pile of unopened mail, saying, “I can’t do that, I have ADHD.” »
In another scenario, a student asks me for a medical note exempting him from a written assignment. No extra time, no quieter room, no help dividing the work into steps: they want the mission abandoned.
I see both situations often in my Mexico City clinic. They raise the same question: Does a diagnosis of attention-deficit/hyperactivity disorder explain why a task is more difficult? Usually, yes. Does it determine which tasks the person should stop undertaking? Rarely.
I am a liaison psychiatrist at the National Medical Center “20 de Noviembre” in Mexico City and professor of medicine at the National Autonomous University of Mexico. My work focuses on how psychiatric diagnoses fit into a person’s daily life, including how anxiety and ADHD can be masked. I sign several of these school and work notes each week.
Researchers have begun to measure something I see all the time in the clinic: the place a diagnosis plays in how a person sees themselves.
Used like a map, a diagnostic shows where difficult terrain is and the best route to traverse it. For example, mornings might be when a patient collapses, so we plan for them: medication, more structure, and some skills to practice. Used as an alibi – as an excuse to avoid blame – a diagnosis marks the entire territory as off-limits.
Research suggests that these two uses lead to very different lives: one in which someone spends the day and another that narrows around the diagnosis.
When the label takes up all the space
Psychologists who study chronic illness use the term “illness identity” to refer to the extent to which a diagnosis fits into a person’s self-perception.
A Belgian study of adolescents and young adults with type 1 diabetes described four ways in which a person can behave when faced with a diagnosis: rejection, which involves pretending that the diagnosis does not exist; acceptance, which means “this is part of me, but only a part”; enrichment, which means “it taught me something”; and engulfment, that is to say the moment when it eclipses everything else.
Engulfment is high when a person can no longer describe who they are, what they want, or what they are good at without the diagnosis taking over. The condition stops being something they have and becomes how they define themselves.
In 2025, an Israeli team surveyed 154 adolescents with ADHD to determine how their diagnosis had shaped their self-esteem. The researchers found that participants’ sense of immersion more strongly predicted their quality of life than the severity of their symptoms. Of the four models, engulfment was the only one that explained why worse symptoms coincided with worse living.
The same research group found a similar trend in a second study. In 66 adolescents, the more the diagnosis took over, the worse participants performed on executive functioning, self-management, and quality of life measures — put simply: planning ahead, starting a task, and managing their own routines.
These are snapshots, not experiences. They show that self-identity and well-being are linked, but they cannot tell us which motivates the other. Despite this, the pattern is what parents describe to me as the moment when their child stops saying “This is hard for me” and starts saying “This is who I am.”

“It’s my brain” can slow down efforts
Brain differences in people with ADHD are real. Yet the way clinicians, teachers and parents explain a diagnosis can fuel a loop of disempowerment.
Meta-analyses bring together the results of numerous studies. One, co-authored by psychologists at the University of Melbourne, found that when a mental health problem is explained in biological terms – such as a matter of genes or brain chemistry – blame decreases, which is a good thing.
But a second meta-analysis, carried out by another group of Melbourne psychologists, found that brain-based explanations create pessimism about recovery, which is not good.
The same explanation that eliminates blame can also reduce expectations of change.
Avoiding something usually makes it more threatening
One type of support can keep someone engaged in a task they find difficult: an essay divided into stages with a deadline for each, or a teacher who checks in at the beginning of a lesson rather than at the end. Another type can delete the task.
The first develops skills. The second teaches that the task is truly impossible.
Researchers who study childhood anxiety call this second type “family accommodation,” and it means something specific: a home gradually reorganizes itself so that the child never has to face what scares him. Someone answers the phone for the teenager who dreads phone calls, or the family no longer has people over because visitors make the child anxious.
In schools, “accommodation” means something else: a change in setting, such as extra time or a quieter room, so that the student can still complete the task. To avoid confusion, I call this school version “support”.
No one is asking families to be tougher or less understanding. But a Spanish meta-analysis found that the tendency to suppress the feared situation is linked to more severe anxiety in children and adolescents.
A randomized trial showed that parent-only treatment was as effective as child treatment. Parents learned to react in a supportive manner while taking a step back to save their child from what frightened them.
Teachers and school staff can also distract students from difficult tasks, often without realizing it. When a panel of experts examined the academic supports offered to 76 anxious students in treatment, some pushed the student toward the difficult task and others pushed the student away. Students with social anxiety most often chose those that allowed them to avoid exactly what they feared: being seen and heard by their classmates.
Support and treatment are not the same thing
Educational supports are by far the most common response to ADHD in schools. Many families ask me for a letter requesting additional time for exams. One study found improved reading comprehension among students with ADHD – but roughly equal improvement among their peers without the disorder. So extra time helps, but not in the way that treatment does.
Most supports have no specific benefit for students with this disorder. This does not make them useless; many help any student. This means that it is not a treatment: a student can benefit from many supports for years while the attention problem remains where it was.
After a diagnosis, practical work focuses on medications, therapy, structure and a list of tasks divided into smaller parts. I give this written list to each patient before their departure.

Where does that leave the person in my office?
When I write a school or work note, three things belong in it. First, the specific task the person is struggling with. Second, support that keeps them engaged in this task rather than drifting away from it. Third, a date to see it again: a medium that no one looks at anymore ceases to be a clinical decision and becomes a permanent part of someone’s life.
A good diagnosis does not absolve responsibility. This moves him. The question ceases to be, “Why can’t I?” » It becomes more: “What should I work on and with what help?”
The young person who has learned to say “I can’t, I have ADHD” is not mistaken about the diagnosis. They only have the rest of the sentence left to write.
