Dr. Kennedy conducts thorough ADHD evaluations that go beyond screening questionnaires. His background in neurogenetics informs how he selects and monitors stimulant and non-stimulant medications, and his clinical experience with high-performing professionals means he recognizes the specific ways ADHD presents in adults who have compensated for years.
Understanding ADHD in Adults
ADHD is a clinical diagnosis that affects concentration, working memory, organization, and the ability to follow through on tasks. In high-performing professionals, adult ADHD often presents as a lifetime of "compensated" symptoms that can eventually lead to burnout. Symptoms have typically been present since childhood but may not have been recognized or treated, especially in high-performing individuals who developed coping strategies early.
How ADHD Presents in Adults
Adult ADHD does not always look like the hyperactive child most people picture. Common presentations include:
- Difficulty sustaining attention on a single task, frequently switching between multiple projects or browser tabs
- Starting projects with enthusiasm but struggling to follow through on the less exciting details
- Trouble organizing complex tasks, meeting deadlines, or keeping track of multiple priorities
- Watching TV or playing background media while working, because silence makes focus harder
- Impulsive decision-making or speaking without thinking through consequences
- Chronic lateness or difficulty estimating how long tasks will take
- A pattern of good ideas that never reach completion
Many professionals compensate for these symptoms for years. They find workarounds, develop systems, and push through with sheer effort. They often do not realize how much energy they are spending simply staying afloat until they start treatment.
"It is interesting to see how well these patients can respond to medication. They find that they are able to be a lot more productive, as they probably don't appreciate how much effort they are expending in simply 'staying afloat.'"
ADHD and Related Conditions
ADHD frequently overlaps with anxiety and executive burnout. The overlap between anxiety and ADHD is particularly important because both conditions cause difficulty concentrating, but the treatments are very different.
"There is a lot of overlap between anxiety and ADHD, in that both can cause difficulties with focus and sustained attention. However, the treatment for anxiety is very different. Treating someone with anxiety with a stimulant can cause worsening anxiety and distress."
ADHD medications can also cause insomnia, which requires careful management of timing and dosing.
Why Seek Treatment for ADHD
Adults with untreated ADHD are often surprised by how much treatment changes their daily life. Benefits include:
- Sustained focus on tasks without constantly jumping between activities
- Ability to complete projects through to the less exciting final stages
- Improved organization and time management
- Reduced impulsive decisions and emotional reactivity
- Better performance at work without the exhausting effort of compensation
- Improved relationships, since untreated ADHD affects communication and follow-through
- Fewer missed deadlines, lost items, and forgotten commitments
Treatment does not change who you are. It lowers the barriers that prevent you from functioning at your actual capacity. The goal is to support executive function and facilitate a return to your baseline professional performance.
The Clinical Approach to ADHD
Treatment for ADHD at Kennedy Psychiatric starts with a thorough diagnostic evaluation, followed by psychiatric treatment and, when appropriate, therapy.
Evaluation and Diagnosis
ADHD is a clinical diagnosis. There is no blood test or brain scan. Dr. Kennedy conducts evidence-based evaluations to correctly make the diagnosis and differentiate ADHD from look-alike conditions. The evaluation is a detailed interview focused on cognitive function, working memory, organizational skills, and a history of symptoms stretching back to childhood.
"The evaluation process is a detailed interview with a specific focus on areas of cognitive function, working memory, and organizational skills to put together a detailed evaluation that supports the diagnosis. It also helps exclude other conditions that may mimic ADHD."
Dr. Kennedy often treats parents of children who have been diagnosed with ADHD. They report they have had similar symptoms and problems throughout their lives yet never received treatment. It was only when their child was diagnosed that they recognized the pattern in themselves.
This evaluation step is critical. Anxiety, depression, sleep deprivation, and burnout can all mimic ADHD symptoms. If the underlying issue is anxiety and a patient is prescribed a stimulant,
This evaluation step is critical. Anxiety, depression, sleep deprivation, and burnout can all mimic ADHD symptoms. If the underlying issue is anxiety and a patient is prescribed a stimulant, the results can exacerbate anxiety symptoms and increase clinical distress.
Dr. Kennedy's evaluation takes 60 to 90 minutes. This is not a five-minute online quiz.
Online Assessments vs. In-Person Evaluation
Online ADHD screeners like the ASRS scale can highlight symptoms, but they cannot rule out other conditions that look like ADHD.
"The test does not exclude other conditions that can mimic ADHD, and there is no replacement for an evaluation by an experienced clinician to make the diagnosis and to ensure that treatment is appropriate."
Medication
Following a confirmed ADHD diagnosis, Dr. Kennedy may prescribe stimulant or non-stimulant medications depending on the patient's history, symptoms, other conditions, and response to previous treatments. Treatment plans include

, paired with behavioral strategies to enhance focus and workplace productivity.ADHD treatment includes stimulant and non-stimulant options. We will discuss the treatment option most appropriate for you during our initial evaluation.
"There is a lot of variability in how quickly they act, how long they last for, and it is important to match treatment to a patient's specific needs and symptoms."
Dr. Kennedy may also utilize GeneSight pharmacogenomic testing to guide medication selection based on a patient's unique genetic profile.
The medications described here represent some available options. The specific treatment plan is always based on a thorough individual evaluation.
Stimulants are controlled substances with potential for dependence. Dr. Kennedy manages these medications carefully, with regular follow-ups and monitoring.
"These medications are controlled substances and have the potential for dependence, so it is important to work with an experienced clinician who can manage these medications safely."
CBT and Behavioral Strategies
CBT for ADHD focuses on building organizational systems, managing time, and reducing the impact of impulsivity on daily life.

Comparing ADHD Treatment Approaches
| Approach | Best For |
|---|---|
| Stimulant medication + behavioral strategies | Most adults with confirmed ADHD |
| Non-stimulant medication | Patients with anxiety, heart conditions, or stimulant sensitivity |
| CBT for ADHD | Patients who need organizational and time management support |
| Medication management only | Patients already in therapy elsewhere |
Dr. Kennedy determines the best approach during the initial evaluation. Most patients start with medication and add behavioral strategies as needed.
What to Expect from ADHD Treatment
ADHD medication typically works faster than medications for anxiety or depression.
- Stimulant medications often have a rapid onset of action, frequently within the first day of treatment, though finding the optimal dose is a gradual process
- Finding the right medication and dose may take several follow-up adjustments
- Non-stimulant medications take longer to reach full effect, typically two to four weeks
- CBT strategies can be applied immediately once learned
- Most patients notice meaningful improvement in focus and productivity within the first month
Treatment is not about becoming a different person. It is about removing the barrier that has been forcing you to work harder than necessary to stay on track.

A detailed interview covering cognitive function, working memory, organizational patterns, symptom history from childhood to present, and a review of other conditions that may mimic ADHD. Dr. Kennedy evaluates whether symptoms are due to ADHD, anxiety, or both.
If ADHD is confirmed, Dr. Kennedy discusses medication options collaboratively with the patient. The decision is always made together.
"The course of treatment is decided upon collaboratively with the goal of reducing the risk of any adverse effects."
Treatment can begin at the first appointment if appropriate.
Regular follow-ups, typically at least once every two months for patients on stimulant medications. These appointments monitor medication effectiveness, side effects, and any changes in blood pressure or heart rate. Dr. Kennedy coordinates closely with patients' primary care doctors and, when appropriate, with specialized therapists.
"Good clinical care means following up closely with patients on these medications. I also coordinate closely with patients' primary care doctors."
ADHD is a chronic condition. Some patients stay on medication long-term, while others develop enough compensatory strategies to reduce or discontinue medication. Dr. Kennedy works with each patient to determine the right approach for their situation, always with the goal of maximizing independence and high-level functioning.

Dr. Kennedy provides both medication and therapy. If ADHD coexists with anxiety, both can be treated by the same provider without the delays of coordinating between a prescriber and a separate therapist.
Frequently Asked Questions About ADHD Treatment
Diagnosis and Development
Did I "develop" ADHD as an adult?
Clinically, ADHD is a neurodevelopmental disorder, meaning symptoms must be present before age 12. However, many high-achieving professionals are not diagnosed until adulthood. Peer-reviewed studies on "late-onset" ADHD suggest that high intelligence or supportive environments often mask symptoms in childhood. These symptoms typically become impairing only when adult responsibilities exceed an individual's ability to compensate.
What is the difference between ADD and ADHD?
"ADD" is an outdated clinical term from the 1980s. The current medical diagnosis is ADHD, which is divided into three presentations:
- Predominantly Inattentive: Difficulty with focus, organization, and "internal" distractibility (formerly ADD).
- Predominantly Hyperactive-Impulsive: Physical restlessness and verbal impulsivity.
- Combined Presentation: Evidence of both inattention and hyperactivity.
Can ADHD be diagnosed without a "brain scan" or computer test?
Yes. According to the American Academy of Pediatrics and Goldberg et al. (2020), the gold standard for adult ADHD diagnosis is a comprehensive clinical interview. While computer-based tests (like the CPT) can provide supplementary data, they have high false-negative rates in high-IQ adults. A thorough history of your childhood and current functional impairment is the most reliable diagnostic tool.
Comorbidity: ADHD and Anxiety
Can ADHD cause chronic anxiety?
There is a high rate of comorbidity (co-occurrence) between these two. Constant struggles with deadlines, forgetfulness, and "executive overload" create a state of chronic stress that can manifest as secondary anxiety. Peer-reviewed data indicates that roughly 25-40% of adults with ADHD also meet the criteria for an anxiety disorder.
Does stimulant medication help with anxiety?
Stimulants are not indicated for the treatment of primary anxiety disorders. In fact, because they increase norepinephrine and dopamine, they can exacerbate physical anxiety symptoms (racing heart, jitters). However, if your anxiety is strictly a result of ADHD-related chaos, successfully treating the ADHD may lower your overall stress levels. Dr. Kennedy performs a differential diagnosis to ensure stimulants are appropriate for your profile.
How do you treat both conditions simultaneously?
The clinical priority is to determine which condition is "primary" (causing the most impairment). Treatment may involve:
- Sequencing: Stabilizing anxiety before introducing a stimulant.
- Non-Stimulants: Using non-stimulant medications that treat ADHD symptoms without the "jittery" side effects of stimulants.
- Combined Protocols: Low-dose long-acting stimulants paired with targeted CBT for anxiety.
