Adult ADHD is real — and treatable.
Many adults arrive at consultation after decades living with forgetfulness, difficulty finishing what they start, procrastination, scattered focus, and a tiredness that cannot be explained by work alone. Adult ADHD rarely resembles the hyperactive child who stopped moving: what persists is the attentional and executive pattern.

What is ADHD in adults?
Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that begins in childhood and, in a significant proportion of people, persists into adult life: the symptoms causing impairment continue into adulthood in up to 75% of cases diagnosed in childhood. It is estimated that approximately 2.5% of the adult population worldwide lives with persistent ADHD. It is, therefore, one of the most frequent neurodevelopmental conditions in adults—and one of the most underdiagnosed.
Diagnosis is governed by DSM-5-TR, which requires that several symptoms have been present before age 12 and manifest in two or more contexts (for example, work and home). In adults, the threshold is at least five symptoms of inattention and/or hyperactivity-impulsivity—one fewer than in children—in recognition that symptom expression changes with age. This is why many people receive the diagnosis only in their second, third, or fourth decade.
In adults, the attentional dimension predominates over the hyperactive one. The motor hyperactivity typical of childhood tends to transform into internal restlessness, difficulty relaxing, or a mental motor that never turns off. Inattention, by contrast, persists and is often what most interferes with daily life: work, relationships, finances, time management.
It is not a matter of willpower or intelligence. It is a neurobiological difference with a robust genetic component: twin studies estimate heritability at approximately 74%, placing it among the most heritable psychiatric disorders.
Common signs in consultation
Not all people with ADHD present the same symptoms or with the same intensity. Some signs that bring an adult to consultation:
Chronic procrastination of important tasks even when aware of the consequences.
Difficulty starting and maintaining long-term projects; many starts without completion.
Recurrent forgetfulness of appointments, deadlines, and everyday objects.
Erratic time management underestimating how long a task takes, arriving late, losing hours on non-priorities.
Interrupted reading reading the same page several times without retaining.
Difficulty regulating emotions outbursts of frustration followed by guilt or shame.
Internal sense of restlessness or feeling like a thousand tabs open in your head.
Hyperfocus on tasks of interest, alternating with complete shutdown for those that don't.
Demanding school history poor performance despite preserved intelligence, or disproportionate effort for average results.
It is common for ADHD to be accompanied by anxiety or depression. Evidence shows high rates of comorbidity, partly as a consequence of years of maladaptive coping. Identifying underlying ADHD changes the treatment approach: treating only anxiety or depression without recognizing the underlying ADHD typically yields partial results.
ADHD in adult women
For decades, ADHD was understood through the lens of the hyperactive boy, and this left many women off the radar. The wide gap in the proportion of diagnoses between men and women is explained, at least in part, by less recognition and referral bias—not by lower actual prevalence.
In women, the inattentive and internalized presentation usually predominates: less visible hyperactivity and more disorganization, scattered focus, forgetfulness, and a constant sense of working against the clock. Many develop early masking strategies—overeffort, perfectionism, endless lists—that hide the condition at the cost of high emotional wear.
This is why it is common for women to reach diagnosis in adulthood, often after years of treating anxiety or depression—comorbidities especially prominent in women with ADHD—without anyone looking at the underlying attentional pattern. Recognizing ADHD in a woman is not putting another label on her: frequently it is the piece that finally organizes a history that never quite fit.
When to consult?
It is worth formally evaluating when:
- 1
Attentional or organizational symptoms persistently interfere with your work, studies, or relationships.
- 2
You have tried organizational strategies, planners, and apps, and everything works for a few days then collapses.
- 3
Other professionals have already ruled out medical issues (thyroid, anemia, sleep apnea), but the pattern persists.
- 4
You have a family history of ADHD (it is highly heritable).
- 5
You suspect the diagnosis could underlie conditions you already manage (treatment-resistant anxiety, recurrent depression).
A well-made diagnosis is not a label—it is clinical information that opens specific treatment options.
Is it ADHD… or something else?
These contrasts show why the diagnosis is made by a professional — they are not a checklist for self-diagnosis. And many of these conditions can also coexist with ADHD: part of the evaluation is telling what explains what, and treating accordingly.
Is it ADHD or bipolar disorder?
The distinction matters for safety: starting a stimulant on an unrecognized bipolar condition can destabilize it. ADHD is inattention and impulsivity that are constant since childhood; bipolar disorder runs in episodes. Emotional lability alone does not distinguish between them — that is why the course over time is assessed.
Is it ADHD or anxiety?
ADHD is a chronic pattern since childhood; anxiety tends to revolve around worry and specific periods. They also frequently coexist.
Is it ADHD or depression?
The concentration difficulty of depression appears with low mood and improves as mood improves; in ADHD it is constant, independent of mood.
Is it ADHD or burnout?
Burnout is situational —an exhaustion tied to a work period—; ADHD is a stable pattern across life.
Or is it a sleep or thyroid problem?
Certain medical and sleep conditions produce similar symptoms and can also accompany ADHD; that is why they are assessed and ruled out.
How I approach treatment
The evaluation is carried out through the psychiatric interview, as the diagnosis is clinical, supported also by validated scales and structured instruments when they add to the case and, as appropriate, by laboratory tests to rule out other causes.
Treatment of adult ADHD is multimodal—combining pharmacological and non-pharmacological interventions, adjusted for severity, comorbidities, and the context of each patient—in line with international guidelines.
Pharmacological management when indicated
Drug choice is individualized according to each case; not everyone requires medication. There are non-stimulant and stimulant options with different efficacy and safety profiles. As a safety principle, I do not start with restricted medication upfront or at the first visit.
Coordination with psychotherapy
My role is diagnosis and medical management. Cognitive-behavioral therapy adapted to ADHD, executive function coaching, or other approaches are developed by psychologists and professionals with whom I work in collaboration.
Coordination with other specialties
Medical consultation in specific cases that warrant it. I perform the ADHD diagnosis in consultation.
Clinical education
Understanding how your own brain works is part of treatment. Good explanation reduces guilt and improves adherence.
Close follow-up
In the first months, with fine-tuning and monitoring of effects.
I maintain specific and current training in adult ADHD—including Harvard Medical School's Current Practice in ADHD: Meet the Experts (2025)—to keep my practice aligned with the best available evidence.
My approach is evidence-based and respectful of your autonomy. I do not medicate at the first visit nor push treatments you don't wish to explore. We make the decision together once the clinical picture is clear.
Frequently asked questions
In how many visits will I know if I have ADHD?
Adult ADHD diagnosis is not rushed to closure. I do not commit to a fixed number of visits: the process is personalized and works with information as it consolidates—detailed history, how the condition unfolds, validated scales when appropriate, and ruling out other conditions that can mimic ADHD. What I guarantee is that evaluation is careful: I do not label quickly to fit the answer the patient expects to hear.
Do I have to take medication?
No. Medication is one tool, not the only one. Some patients benefit enormously from pharmacological treatment; others prefer starting with non-pharmacological interventions and reassessing. The decision is yours, with clear information. When medication is indicated, my first approach is not restricted drugs.
What medication will I take?
It depends on each case—there is no single answer nor do I decide it in advance. Treatment is individualized according to your clinical picture, your comorbidities, and your tolerance; not everyone needs medication. As a safety principle, I do not start with restricted medication upfront.
Can I do the first visit by videoconference?
Yes. The initial evaluation for adult ADHD can be conducted perfectly via telepsychiatry. What matters is that you have a quiet, uninterrupted space for the full hour.
Do you see people who prefer care in English?
Yes. I conduct consultations in English with the same fluency as in Spanish, which is relevant for expatriates living in Lima, executives in multinational companies, or people who simply prefer to express themselves in English about intimate topics.
