Wondering whether it’s really ADHD? A comprehensive adult ADHD evaluation can help separate ADHD from anxiety, depression, poor sleep, trauma, hormonal changes, medication effects, and other conditions that can cause similar problems with focus and executive function. Resonance Psychiatry offers structured adult ADHD evaluations in Everett and by telehealth across Washington, combining detailed clinical assessment, standardized questionnaires, objective attention testing, and a personalized diagnostic report you can keep and share with your treating clinician.
Adult ADHD Q & A
Do I Have Adult ADHD?
Difficulty focusing does not automatically mean ADHD.
Adults seeking an ADHD evaluation often describe procrastination, forgetfulness, disorganization, poor follow-through, difficulty starting or finishing tasks, mental restlessness, overwhelm, or feeling as though their brain is constantly jumping between things.
Those symptoms are real. But they are not unique to ADHD.
Anxiety, depression, chronic sleep loss, sleep apnea, trauma, hormonal changes, medications, substance use, learning differences, and certain medical or neurologic conditions can produce remarkably similar problems with attention and executive functioning.
That is why the goal of an adult ADHD assessment should not simply be to determine whether you endorse enough ADHD symptoms.
The more important question is:
What is causing those symptoms?
A More Comprehensive Adult ADHD Evaluation
At Resonance Psychiatry, ADHD evaluation is approached as a process of diagnostic clarification.
Instead of relying on one screening questionnaire or a brief conversation, your assessment brings together multiple sources of information to determine whether the overall pattern is consistent with ADHD and whether another condition may better explain, contribute to, or coexist with your symptoms.
The evaluation looks at your current concerns, childhood history, functioning across different settings, medical and psychiatric history, sleep, mood, anxiety, medications and substances, and other factors that can affect attention.
ADHD is a neurodevelopmental disorder, meaning the underlying pattern begins in childhood even when someone is not diagnosed until adulthood. Many adults, particularly those who were bright, highly structured, or able to compensate when they were younger, may not recognize the pattern until the demands of adult life exceed the strategies that once worked.
A thoughtful evaluation looks backward as well as at what is happening today.
What Does the Adult ADHD Assessment Include?
Your evaluation is completed in several parts so that no single questionnaire, interview answer, or test result determines the diagnosis.
1. Comprehensive questionnaire battery
Before your diagnostic interview, you complete 13 structured questionnaires and screening measures.
These help assess ADHD symptoms while also looking for common conditions that can mimic or complicate ADHD, including problems involving:
- anxiety
- depression
- sleep and insomnia
- possible sleep apnea
- trauma-related symptoms
- bipolar-spectrum symptoms
- substance use
- autistic traits
- childhood ADHD symptoms
- medical, neurologic, learning, and cognitive factors
The purpose is not simply to generate scores. The questionnaires help identify patterns that deserve closer investigation during the clinical interview.
2. 60-minute diagnostic interview
Next, we complete a detailed clinical interview focused on how your symptoms actually appear in everyday life.
Rather than stopping at questions such as “Do you have difficulty concentrating?”, we look for concrete examples:
What happens when you try to start a difficult task?
What did similar problems look like during childhood?
Do the symptoms occur in several areas of your life?
When did they begin?
Are there periods when they disappear or become substantially worse?
Could anxiety, depression, sleep disruption, hormones, medications, or another condition better explain the change?
This allows us to distinguish a symptom from the process producing it.
3. Objective sustained-attention testing
Your assessment also includes a computerized Sustained Attention to Response Task (SART).
The SART measures aspects of sustained attention and response control. It does not diagnose ADHD by itself.
Instead, the results provide another piece of objective information that can be interpreted alongside your history, questionnaires, observed clinical pattern, and other findings.
That distinction matters. There is no single computerized test, questionnaire, or laboratory result that independently establishes an ADHD diagnosis.
4. Diagnostic feedback and visual report
After the information has been reviewed together, you receive a follow-up appointment devoted to your results.
Rather than simply hearing “yes, ADHD” or “no, ADHD,” you receive a clear explanation of:
- your questionnaire findings
- relevant patterns from the clinical interview
- your attention-test results
- whether the evidence supports ADHD
- other diagnoses or contributors identified during the assessment
- treatment considerations
- recommended next steps
You also receive a concise visual diagnostic report summarizing your evaluation.
The report is yours to keep and can be shared with your primary care provider, therapist, psychiatrist, or other prescribing clinician.
That last point is a strong differentiator. Other Washington ADHD assessment practices prominently advertise a usable written report and the ability to take results to another clinician, which suggests this is something prospective patients actively value. Steinberg PhD
What Else Can Look Like ADHD?
A major part of a high-quality ADHD evaluation is differential diagnosis.
Problems with attention, working memory, organization, motivation, and emotional regulation can occur with:
Anxiety
Persistent worry and mental scanning can consume attention and make concentration, task initiation, and working memory more difficult.
Depression
Depression can cause poor concentration, slowed thinking, low motivation, impaired memory, and difficulty initiating tasks.
Poor sleep and sleep disorders
Chronic sleep restriction, insomnia, sleep apnea, and other sleep disorders can impair attention, working memory, executive functioning, and emotional regulation.
Trauma and chronic stress
Hyperarousal, intrusive thoughts, disrupted sleep, and persistent threat monitoring can all interfere with concentration.
Hormonal changes
Changes associated with the menstrual cycle, pregnancy, postpartum period, and perimenopause can affect sleep, mood, cognition, and attention.
Bipolar-spectrum conditions
Changes in attention, energy, impulsivity, activity level, and sleep can sometimes be confused with ADHD. The timeline and episodic versus lifelong nature of symptoms are particularly important.
Medications, substances, and medical conditions
Medication effects, alcohol or other substances, neurologic conditions, thyroid disease, and other medical factors can also contribute to changes in cognition or attention.
Sometimes ADHD and another condition are both present.
The purpose of the evaluation is not to find a reason not to diagnose ADHD. It is to determine which explanation best fits the complete pattern.
ADHD Testing vs. ADHD Screening
Online ADHD quizzes and screening questionnaires can be useful starting points.
They are not the same thing as a diagnostic evaluation.
A screening test asks essentially:
“Are enough symptoms present that ADHD should be investigated further?”
A diagnostic assessment asks:
“Does the complete history and pattern meet criteria for ADHD, and is ADHD the best explanation for what is happening?”
That second question requires considerably more information.
This is why Resonance Psychiatry combines standardized ADHD screening, broader psychiatric and sleep assessment, childhood history, clinical interviewing, and objective attention data rather than relying on one score.
What If the Evaluation Does Not Show ADHD?
That is still useful information.
The purpose of an evaluation is clarity, not obtaining a predetermined diagnosis.
If ADHD does not appear to explain your symptoms, your results can help identify what deserves attention next, such as anxiety, depression, sleep problems, trauma, hormonal changes, another psychiatric condition, or a medical contributor.
You leave with a clearer picture of what the evaluation found and recommendations for appropriate next steps.
