Home / Las Colinas, TX / ADHD Testing and Treatment
Las Colinas sits at the corporate heart of DFW—Fortune 500 headquarters, international business travel through one of the world’s busiest airports, and a workforce that includes transferees and professionals from across the country and around the world. ADHD shows up across all of these populations, often quietly, often masked by demanding work and the cultural expectation in many communities that you handle things on your own. It deserves specialty care that’s familiar with the realities our patients actually navigate—discreet, evidence-based, and respectful of the wide range of backgrounds people bring with them.
Our location at 1507 LBJ Freeway, Suite 750 technically sits just over the line in Farmers Branch (75234), but it serves the Las Colinas/Irving corridor and is immediately accessible from I-635 (LBJ Freeway), the President George Bush Turnpike, and SH-114. Patients coming from Las Colinas, Irving, Coppell, Carrollton, Addison, Grapevine, Euless, and the surrounding Mid-Cities can typically reach us in 15 to 20 minutes—and DFW Airport is less than 15 minutes away. We’re open Monday through Friday from 6:00 AM to 9:00 PM and Saturday from 7:00 AM to 7:00 PM, with same-week appointments available.
ADHD (attention-deficit/hyperactivity disorder) is a neurodevelopmental condition that affects the brain systems responsible for attention regulation, impulse control, working memory, time perception, and executive function—the set of skills involved in planning, starting, and completing tasks. ADHD is biological, it’s heritable (running strongly in families), and it persists across the lifespan in most people who have it. It is not caused by parenting, sugar, screen time, or moral failure.
There’s no blood test for ADHD, but it’s one of the most well-studied conditions in psychiatry, and diagnosis through careful clinical evaluation is reliable when done properly. The challenge is that ADHD symptoms overlap with many other conditions—anxiety, depression, sleep disorders, trauma history, learning disorders, autism spectrum, thyroid problems, and the ordinary stresses of modern life—which is why a careful diagnostic process matters more than a quick checklist.
ADHD presents in three main patterns, and people often shift between them across the lifespan:
Predominantly inattentive presentation. The pattern that used to be called “ADD.” Difficulty sustaining attention, easily distracted, trouble finishing tasks, disorganization, forgetfulness, losing things, appearing to not listen when spoken to, daydreaming. This presentation is most often missed in girls, in quiet kids, in high-achieving students who compensate hard, and in adults who appear functional but exhaust themselves doing so.
Predominantly hyperactive-impulsive presentation. Fidgeting, restlessness, difficulty staying seated, talking excessively, interrupting, blurting out answers, difficulty waiting, acting before thinking. This is the most visible pattern and the one most likely to get noticed early, especially in boys. In adults, the physical hyperactivity often quiets into internal restlessness while the impulsivity remains.
Combined presentation. Significant symptoms across both inattentive and hyperactive-impulsive categories. This is the most common presentation in patients formally diagnosed.
In children, ADHD often shows up first at school, where the demands of sustained attention, organized work, and impulse control are highest. Common signs include:
Attention and focus. Difficulty paying attention in class, careless mistakes, trouble following multi-step directions, losing homework and supplies, appearing to not listen, daydreaming, difficulty finishing tasks they started.
Activity and impulsivity. Fidgeting, getting out of seat, running or climbing when it’s not appropriate, talking excessively, interrupting, blurting out answers, difficulty waiting turn, acting without thinking.
Organization and executive function. Difficulty managing time, trouble starting homework, losing things, forgetfulness, messy backpacks and lockers, missed deadlines, last-minute everything.
Emotional regulation. Frequent frustration, emotional intensity that seems out of proportion, difficulty handling transitions, big feelings that come on fast and pass quickly. Emotional dysregulation isn’t in the formal DSM criteria for ADHD, but it’s one of the most common features.
Social and family impact. Conflicts with siblings, difficulty with peer relationships, parental exhaustion from the daily management, homework battles that take three hours for thirty minutes of work.
Adult ADHD often looks different than childhood ADHD. The hyperactivity that was visible in kids becomes internal restlessness in adults, while the attention and executive function challenges remain or become more disabling as life demands grow. Common adult patterns:
Work and career. Procrastination on important tasks (with last-minute scrambles), missed deadlines, difficulty starting projects, trouble with sustained focus during meetings, brilliant work followed by stretches of unproductivity, hitting a career ceiling because the executive function demands have outgrown your compensatory strategies, repeated job changes when the novelty wears off.
Time and planning. Chronic lateness despite trying, underestimating how long things take, difficulty managing multiple deadlines, the experience of time as “now and not-now” rather than as a continuous progression.
Home and relationships. Household tasks pile up, finances slip through the cracks, partners frustrated by uneven contribution, important things forgotten, the persistent guilt of being “supposed to be better at this.”
Emotional patterns. Rejection sensitivity (intense reaction to perceived criticism or rejection), emotional intensity, difficulty regulating mood across the day, restlessness when not stimulated, the need for novelty and the boredom of routine tasks.
Self-perception. A lifetime sense of underperforming relative to potential. The exhausting work of compensating. The feeling of being “lazy” or “broken” that doesn’t match how hard you’ve actually been trying. For many adults, getting an accurate diagnosis is the first time someone has named what’s been going on—and that recognition itself is significant.
Adult ADHD is one of the largest patient populations we see, and the path to diagnosis often follows recognizable patterns:
The child-diagnosed pathway. Many parents bring their child in for evaluation, hear the symptoms described, and realize they recognize themselves. ADHD runs strongly in families—if your child has it, there’s a meaningful chance you do too. We see this regularly, and it’s often the start of much-needed adult treatment that should have happened years earlier.
The wall-hit pathway. Compensatory strategies that worked in your twenties—coffee, deadline pressure, a partner who handled the organization, the structure of school—stop working in your thirties or forties when life demands grow. A new job, a new baby, a divorce, a promotion, a parent who needs care, a partner who isn’t picking up the slack anymore. The system breaks, and the underlying ADHD becomes impossible to mask.
The treatment-resistant pathway. Many adults have been treated for years for anxiety or depression that didn’t fully respond, with the underlying ADHD never identified. About half of adults with ADHD have a co-occurring mood or anxiety condition, and treating only the depression or anxiety usually doesn’t work. When we identify ADHD in patients already in treatment for something else, we adjust the plan to address the actual full picture.
The grief and relief of late diagnosis. Many adults experience a complicated mix of feelings after diagnosis—relief at finally having an explanation for decades of struggle, grief for the time and energy lost to undiagnosed ADHD, and sometimes anger at having been mislabeled as lazy, scattered, or unmotivated for years. These reactions are normal and worth discussing as part of treatment.
It’s not too late. Patients sometimes worry that diagnosis in their 40s, 50s, or 60s is “too late” to matter. It isn’t. Treatment improves daily function, work performance, relationships, and quality of life at any age. The patients we see most often tell us that they wish they had come in years sooner—and that the only thing they wish they’d done differently was to come in faster once they suspected.
Las Colinas is one of the most internationally diverse corporate communities in DFW, and adult ADHD in our patient population often carries dimensions that standard clinical content rarely addresses. Naming these patterns matters because they’re real, they’re common, and they’re frequently missed when patients see clinicians unfamiliar with the context:
Diagnosis as adults who grew up where ADHD wasn’t named. Many adults from countries and cultures where ADHD wasn’t widely diagnosed in their childhood recognize the pattern in themselves only as adults. This isn’t because their ADHD developed later—it’s because the diagnostic framework wasn’t part of their childhood medical experience. The kid who couldn’t sit still in school, who lost things constantly, who was bright but couldn’t seem to follow through, often grew up to be the adult who’s still doing the same things and finally wondering what’s going on.
Recognizing your own ADHD through your child. A common pathway for international families: a child is evaluated for ADHD in the US school system, the parent hears the symptoms described, and suddenly sees decades of their own life from a different angle. This is often the start of meaningful adult treatment that should have happened twenty or thirty years earlier.
Cultural framing and adult diagnosis. Some patients are skeptical of the ADHD framing, particularly those from cultures where the symptoms get described differently—as personality, as energy, as discipline, as not being raised carefully enough. We don’t dismiss those framings, and we don’t pressure patients toward diagnosis or medication. The evaluation is honest: if the criteria are met and treatment would help, we say so; if they’re not, we say that too. Treatment is always your choice.
Corporate work and the executive function load. H-1B workers, transferees, and international professionals navigating US corporate culture face an executive function load that often exceeds what they navigated at home—different work norms, performance review cycles, complex compliance environments, project management software, simultaneous translation of communication styles, and the ongoing background load of immigration status. For adults with ADHD, this combination can quickly become overwhelming, and what looks like cultural adjustment fatigue is sometimes underlying ADHD becoming visible under load.
Medication concerns specific to international patients. Some patients have concerns about stimulant medication shaped by cultural messaging, by experiences with controlled substance regulations in their home country, or by family attitudes that differ from US clinical norms. We take these concerns seriously, offer non-stimulant alternatives, and never push medication on patients who would prefer to start with non-medication approaches.
Linguistic and cultural responsiveness. We provide care that is respectful of the cultural contexts patients bring with them. For patients who prefer therapy referrals in another language, we make those when we can.
Many of our Las Colinas patients fly through DFW regularly for work—domestic business travel, international assignments, project rotations, client visits, and the cumulative life of frequent fliers. Travel and ADHD interact in several practical ways worth naming:
Medication timing across time zones. Long-acting stimulant medications work on a roughly 8-to-12-hour cycle, which is straightforward at home and complicated across multiple time zones. We work with patients on practical approaches: how to handle medication during transit, whether to maintain home time or adjust to local time, when to schedule the dose around important meetings, and how to manage the inevitable disruption that travel produces.
Sleep disruption. Jet lag and disrupted sleep amplify every ADHD symptom—attention falls, emotional regulation worsens, impulsivity rises, executive function degrades. Frequent travelers often have a steady-state sleep deficit that compounds underlying ADHD. We address sleep as part of the treatment plan, not as a separate issue.
International travel and controlled substances. Schedule II stimulant medications are regulated differently across countries. Patients traveling internationally need to be aware that some countries restrict or prohibit medications that are routinely prescribed in the US, that import quantities are sometimes limited, and that documentation requirements vary. We provide letters of medical necessity and prescription documentation when appropriate, and we recommend patients check destination-country regulations through official channels before traveling.
The executive function load of travel itself. Packing, navigating airports, hotel logistics, schedule management, expense reporting, time-zone coordination, and the broader cognitive overhead of frequent travel are heavy on executive function. For adults with ADHD, the travel itself can be the most exhausting part of an assignment. Treatment doesn’t eliminate this load, but it can substantially reduce the daily wear.
Concerns about confidentiality are legitimate and common in tight corporate communities, and they take on additional weight for patients with immigration status concerns, employer-sponsored benefits, security clearance considerations, or specialized roles. For ADHD specifically, patients sometimes have additional concerns about prescription records appearing in pharmacy benefit data, drug-testing concerns, and the general question of whether seeking neuropsychiatric evaluation will affect their career.
Mental health treatment records are protected by HIPAA, and your employer cannot access them without your written authorization. Treatment for ADHD generally does not affect career standing or status, though specific situations vary and patients with clearance, licensure, or status concerns are encouraged to consult with the relevant authority or attorney for guidance specific to their case. For patients who prefer not to use prescription stimulants because of work or career considerations, non-stimulant medications and behavioral approaches are available alternatives that may better fit your situation. We work to make care discreet, with extended hours that don’t require explaining absences and clear conversations about what is and isn’t shared with anyone.
Beyond the international and business travel populations, certain other patterns show up frequently:
Corporate professional ADHD. Fortune 500 headquarters across Las Colinas employ tens of thousands of professionals whose work involves long-form project management, status reporting, meeting cycles, deliverables across multiple workstreams, and the executive function load of modern corporate life. Many of these workers have undiagnosed ADHD that becomes visible at career transitions—promotions into management, role changes, project shifts, or simply the cumulative weight of years.
Healthcare worker ADHD. Nurses, techs, EMTs, and clinical staff at the hospital systems across Irving, Carrollton, and the broader North Dallas region carry the same self-selection pattern as theme park or first responder workforces. The fast-paced clinical work fits ADHD neurology; the documentation requirements and administrative dimensions of healthcare are where it becomes disabling.
Pediatric and adolescent ADHD in Mid-Cities families. The Las Colinas/Mid-Cities area has a heavily family-oriented population. Pediatric ADHD evaluation is one of the most common reasons families come to us, often starting with concerns raised by teachers in elementary or middle school. We treat kids and teens across Irving ISD, Coppell ISD, Carrollton-Farmers Branch ISD, Lewisville ISD, Grapevine-Colleyville ISD, and the surrounding districts.
Commute and ADHD driving safety. The corridors that define life here—I-635 (LBJ), the President George Bush Turnpike, SH-114, the Dallas North Tollway—carry heavy traffic, and serious accidents are common. ADHD-related driving difficulty is a real safety concern, particularly on long highway stretches where attention drift becomes dangerous. Treatment can meaningfully reduce driving risk.
ADHD frequently shows up alongside other mental health conditions, and treating only one usually doesn’t work. About half of adults with ADHD have a co-occurring anxiety or depression diagnosis. ADHD often accompanies learning disorders, autism spectrum, sleep disorders, and substance use disorders. Many adults have been treated for anxiety or depression for years before someone notices the ADHD underneath—and the depression or anxiety often improves significantly when the ADHD is properly addressed.
During your first visit, we assess the full picture rather than just the most obvious symptom. Treatment plans that address the actual constellation of what’s going on tend to work better than plans that target one diagnosis in isolation.
Living in North Texas creates conditions that interact with ADHD in ways patients in milder climates don’t experience:
Summer heat and sleep disruption. North Texas summers are long and hot. Sleep disruption from heat amplifies every ADHD symptom—attention falls, emotional regulation worsens, impulsivity rises, executive function degrades. For frequent travelers, this layers on top of jet-lag-related sleep disruption to create particularly difficult stretches.
Indoor confinement. Kids and adults with ADHD often rely on physical activity and outdoor stimulation to regulate. When summer heat keeps everyone indoors, the absence of normal physical outlets can make ADHD harder to manage.
Year-round outdoor recovery in the better seasons. North Texas spring and fall are excellent for outdoor behavioral activation. Movement matters for ADHD, and this region supports it for most of the year.
Childhood and adolescent ADHD typically gets identified first by parents and teachers who notice patterns at school or at home that don’t fit the usual developmental trajectory. We treat kids and teens across the Mid-Cities and North Dallas districts—Irving ISD, Coppell ISD, Carrollton-Farmers Branch ISD, Lewisville ISD, Grapevine-Colleyville ISD—and our approach involves:
Careful diagnostic evaluation. A thorough assessment that includes parent and teacher input, standardized rating scales, careful screening for co-occurring conditions (anxiety, depression, learning disorders, autism spectrum, sleep problems), and—when appropriate—the QbTest for objective measurement of attention and impulsivity.
Family involvement throughout treatment. Parents are an essential part of pediatric and adolescent ADHD care. We coach parents on the behavioral strategies that support kids with ADHD, the communication patterns that reduce conflict, and the ways to advocate for accommodations at school without inadvertently increasing pressure. For bicultural families where parents may have different views on ADHD diagnosis or treatment, we facilitate honest conversations and respect family decision-making.
Coordination with schools. ADHD diagnosis is often a starting point for IEP or 504 accommodations that can include extended time on tests, preferential seating, organizational support, or reduced homework loads. We provide the diagnostic documentation; you and the school work out the specifics.
Adolescents specifically. Teens with ADHD face increased academic demands, social complexity, and the early emergence of decisions about driving, substance use, and relationships—all of which interact with ADHD in important ways. ADHD treatment in adolescence is associated with better long-term outcomes across many domains.
ADHD diagnosis done well isn’t a 15-minute conversation and a prescription. Our evaluation process includes:
Detailed clinical interview. A thorough conversation about current symptoms, lifetime history (ADHD by definition shows up by age 12, even when diagnosis happens decades later), school history, work history, family history, and the specific ways symptoms have affected your life.
Standardized rating scales. Validated questionnaires that you complete (and that parents and teachers complete for kids), which help structure the diagnostic picture.
QbTest computer-based assessment. A 15-20 minute computer-based test that objectively measures attention, impulsivity, and activity. The QbTest doesn’t diagnose ADHD by itself, but it adds objective data to the clinical picture and is particularly useful in distinguishing ADHD from anxiety or other conditions that can mimic it.
Screening for co-occurring conditions. Anxiety, depression, learning disorders, autism spectrum, sleep disorders, substance use, and medical conditions like thyroid problems that can mimic or contribute to ADHD symptoms.
Rule-outs. Sleep disorders (especially obstructive sleep apnea, which can present like ADHD), thyroid problems, medication side effects, substance use, and other conditions that can cause attention symptoms in the absence of ADHD.
Diagnostic feedback. A clear conversation about the findings—what we see, what we don’t see, and what we recommend—rather than a one-line diagnosis and a prescription.
Once we have an accurate diagnosis, treatment is highly individualized. The main components:
Stimulant medications are the most extensively studied and most effective first-line treatment for ADHD in both kids and adults. There are two main families: methylphenidate-based medications (Ritalin, Concerta, Focalin, and others) and amphetamine-based medications (Adderall, Vyvanse, and others). Both families work by enhancing the activity of dopamine and norepinephrine in the brain’s attention and executive function systems. About 70-80% of patients respond to one of the two families, and finding the right medication, formulation, and dose often takes some trial.
Short-acting versus long-acting. Short-acting formulations last 3-5 hours and may be used for specific high-demand parts of the day. Long-acting formulations last 6-12 hours and provide steady coverage across a school or work day. For frequent business travelers and patients with variable schedules, careful timing decisions matter—we work with the actual schedule and travel pattern rather than assuming a standard day.
What patients typically notice. Improved ability to start tasks and sustain attention, reduced procrastination, less internal noise, more ability to follow conversations and meetings, less emotional reactivity, and a general sense of being able to access executive function that was previously out of reach. Most patients describe feeling more like themselves on medication, not less.
Patients often have legitimate questions about stimulants—about safety, dependence, personality changes, side effects, controlled substance considerations, international travel concerns, and the recent national stimulant shortage. We treat these questions seriously.
Safety and addiction. Properly prescribed, monitored, and taken stimulants have a strong safety profile in patients with ADHD. Despite their classification as controlled substances, prescription stimulants taken as directed for ADHD do not produce the addiction pattern seen with recreational stimulant misuse. Importantly, treated ADHD is associated with lower rates of substance use disorders than untreated ADHD—the self-medication risk runs in the other direction.
Side effects. Common side effects include reduced appetite, difficulty falling asleep, headache, mild increase in heart rate or blood pressure, and—occasionally—irritability or emotional flattening that signals the dose is too high. Most side effects are manageable with dose or timing adjustments. We monitor closely, especially in the first few months.
National stimulant shortages. Ongoing supply issues with several stimulant medications have made things harder over recent years. We can’t guarantee a specific medication will be available at a specific pharmacy on a specific day, but we work with you on alternative formulations, on pharmacy options across DFW and the Mid-Cities, and on bridge plans when shortages affect your refill. We don’t write a prescription and disappear when problems arise.
International travel. Stimulant medications are regulated differently across countries. We provide documentation for international travel when appropriate, and we recommend patients check destination-country regulations through official channels before traveling. Some destinations restrict or prohibit medications routinely prescribed in the US.
Controlled substance prescribing. Stimulants are Schedule II controlled substances, which means specific federal regulations around prescribing, refills, and monitoring. There are no automatic refills; we typically see patients regularly for medication management, and we follow standard practices around responsible prescribing. This is not a barrier to care—it’s how we provide care that’s actually accountable.
For patients who don’t tolerate stimulants well, who have specific medical contraindications, who prefer to avoid controlled substances (including for international travel or career reasons), or who haven’t responded to multiple stimulant trials, non-stimulant options are available:
Atomoxetine (Strattera) works through norepinephrine rather than dopamine, takes 4-8 weeks to reach full effect, and provides 24-hour coverage. Particularly useful for patients with co-occurring anxiety, for those who travel internationally and want to avoid controlled substance regulations across countries, or for those who simply don’t want a controlled substance.
Guanfacine (Intuniv) and clonidine (Kapvay) are alpha-2 agonists originally used for blood pressure that have been shown to help with ADHD, particularly with the hyperactive-impulsive and emotional regulation features. Sometimes used alongside stimulants for combination effect.
Bupropion (Wellbutrin) isn’t FDA-approved specifically for ADHD but has good evidence of effectiveness, especially in adults with co-occurring depression.
Viloxazine (Qelbree) is a newer non-stimulant option approved for both kids and adults.
