Do I Have ADHD or Anxiety? How to Tell the Difference
Key Points:
- ADHD and anxiety share many overlapping symptoms including difficulty concentrating, restlessness, and racing thoughts
- ADHD is a neurodevelopmental condition present since childhood, while anxiety can develop at any age
- ADHD involves consistent attention difficulties across all situations, while anxiety-related focus problems are tied to worry
- Many people have both ADHD and anxiety, which requires careful evaluation to treat effectively
- Comprehensive diagnostic testing helps distinguish between the two conditions
Why This Question Matters So Much
You can't focus. Your mind races constantly. You feel restless and on edge. Tasks that should be simple feel overwhelming. You're exhausted from trying to keep up with everything.
So naturally, you start searching for answers. But here's where it gets confusing: the symptoms of ADHD and anxiety look remarkably similar. Difficulty concentrating? Could be either. Racing thoughts? Both. Trouble completing tasks? Check and check.
At Harborside Psychiatry, this is one of the most common questions we hear: "Do I have ADHD or anxiety?" And it's not always a simple answer. Sometimes it's ADHD. Sometimes it's anxiety. Sometimes it's both. Getting the right diagnosis matters because the treatments are different, and what helps one condition might not help the other.
Let's break down the key differences, the overlapping symptoms, and how to figure out what's actually going on.
Understanding ADHD: More Than Just Distraction
ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental condition that affects how your brain manages attention, impulses, and activity levels. It's not something you develop as an adult. If you have ADHD now, you've had it since childhood, even if it wasn't diagnosed.
The Three Types of ADHD
Predominantly Inattentive Type: Difficulty sustaining attention, easily distracted, forgetful, struggles with organization. This type is often missed, especially in women, because there's no obvious hyperactivity.
Predominantly Hyperactive-Impulsive Type: Fidgeting, restlessness, difficulty sitting still, interrupting others, acting without thinking. This is the "classic" presentation that people usually think of.
Combined Type: Symptoms of both inattention and hyperactivity-impulsivity.
Core ADHD Symptoms
ADHD involves persistent difficulties with:
Attention regulation: Trouble focusing on tasks that aren't interesting, even when they're important. Difficulty filtering out distractions. Problems sustaining attention on one thing at a time.
Executive function: Challenges with planning, organizing, starting tasks, managing time, and following through on commitments. Tasks that require multiple steps feel overwhelming.
Impulse control: Acting before thinking, interrupting conversations, difficulty waiting your turn, making impulsive decisions.
Activity regulation: In hyperactive types, this means physical restlessness. In inattentive types, it might be mental restlessness with racing thoughts jumping from topic to topic.
The key characteristic: these symptoms are present consistently, across all areas of life, and have been there since childhood (though you might not have recognized them as ADHD at the time).

Understanding Anxiety: When Worry Takes Over
Anxiety disorders involve excessive, persistent worry that interferes with daily life. Unlike ADHD, anxiety can develop at any age and the symptoms often fluctuate based on stress levels and life circumstances.
Common Anxiety Disorders
Generalized Anxiety Disorder (GAD): Chronic, excessive worry about various aspects of life (work, health, relationships, money) that's difficult to control.
Social Anxiety Disorder: Intense fear of social situations, being judged, or embarrassing yourself.
Panic Disorder: Recurrent panic attacks with physical symptoms like heart pounding, shortness of breath, and sense of impending doom.
Core Anxiety Symptoms
Anxiety involves:
Excessive worry: Your mind fixates on potential problems, worst-case scenarios, and things that could go wrong. The worry feels uncontrollable and out of proportion to actual risk.
Physical tension: Muscle tightness, headaches, jaw clenching, stomach problems, fatigue from constant tension.
Hypervigilance: Feeling on edge, scanning for threats, difficulty relaxing, exaggerated startle response.
Avoidance: Steering clear of situations that trigger anxiety, which can significantly limit your life.
The key characteristic: symptoms are driven by worry and often worse in specific situations or during stressful periods.

The Overlapping Symptoms That Cause Confusion
Here's where it gets tricky. Many symptoms appear in both ADHD and anxiety, which is why people (and sometimes even providers) confuse the two.
Difficulty Concentrating
In ADHD: Attention problems are constant and not limited to anxious situations. You struggle to focus on boring tasks even when you're not worried about anything. Your mind wanders to random topics, not just worries.
In anxiety: Concentration problems happen because your mind is occupied with anxious thoughts. You can focus fine when you're not anxious, but worry hijacks your attention. Your distraction is worry-focused, not random.
Racing Thoughts
In ADHD: Your thoughts jump rapidly from topic to topic, often unrelated. You might be thinking about dinner, then remember you need to call someone, then notice a bird outside, then remember a song lyric. It's scattered and unfocused.
In anxiety: Your thoughts race, but they're circling around worries and concerns. You're thinking about all the things that could go wrong, analyzing past conversations, or planning how to avoid future problems. The racing is worry-driven.
Restlessness
In ADHD: Physical or mental restlessness that's present most of the time, regardless of stress levels. You fidget, tap your foot, need to move, or feel mentally antsy even during calm situations.
In anxiety: Restlessness tied to feeling keyed up or on edge from worry. It typically gets worse during anxious periods and better when you're calm
Trouble Completing Tasks
In ADHD: Task completion is hard because of executive dysfunction. You have trouble starting, staying focused, organizing the steps, or maintaining motivation. This happens with all kinds of tasks, not just anxiety-provoking ones.
In anxiety: You avoid tasks that make you anxious, or worry so much about doing them perfectly that you get stuck. You can complete tasks that don't trigger anxiety just fine.
Sleep Problems
In ADHD: Difficulty falling asleep because your mind won't settle, irregular sleep schedules, trouble with sleep routine consistency. This is chronic and not particularly tied to stress levels.
In anxiety: Insomnia driven by worrying thoughts at bedtime. You can't sleep because you're anxious about tomorrow, replaying today, or worrying about not being able to sleep. Often worse during stressful periods.
Key Differences to Help You Tell Them Apart
While the symptoms overlap, there are important distinctions that help identify which condition you're dealing with:
When Did Symptoms Start?
ADHD: Symptoms must have been present before age 12, even if they weren't recognized or diagnosed. Look back at your childhood. Did you struggle with attention, organization, impulsivity, or hyperactivity as a kid? Many adults with ADHD were called "spacey," "daydreamer," "disorganized," or "messy" growing up.
Anxiety: Can develop at any age. You might have been fine as a child and developed anxiety in your teens, 20s, 30s, or later in response to stress or life changes.
Are Symptoms Situation-Specific?
ADHD: Symptoms are pervasive across all settings. You have attention and organization problems at work, at home, in social situations, everywhere. Some situations might be harder than others (boring tasks are particularly difficult), but the underlying challenges are always present.
Anxiety: Symptoms often vary by situation. Your anxiety might spike in social settings, during performance situations, when facing uncertainty, or in other specific contexts. You might function well in low-stress situations.
What Are You Thinking About?
ADHD: Your mind wanders to random, unrelated topics. You're not particularly worried, just easily distracted by whatever pops into your head or catches your attention in the environment.
Anxiety: Your thoughts are dominated by worry, fear, and anticipation of problems. Even when your mind wanders, it wanders to concerns and potential issues.
How Do You Feel About Tasks?
ADHD: Tasks feel boring or overwhelming because they require sustained attention and organization, not because they make you anxious. You procrastinate because starting is hard, not because you're worried about the outcome.
Anxiety: Tasks feel scary or stressful because you're worried about doing them wrong, being judged, or negative consequences. You avoid them because they trigger anxiety.
Do You Have Physical Symptoms?
ADHD: Restlessness and fidgeting, but typically not the physical anxiety symptoms like heart racing, sweating, or nausea (unless you also have anxiety).
Anxiety: Physical symptoms are common including rapid heartbeat, chest tightness, sweating, shaking, stomach problems, and muscle tension.
Response to Stress
ADHD: Your ADHD symptoms are pretty consistent regardless of stress levels. You might perform worse under stress, but the core symptoms don't come and go with your stress.
Anxiety: Symptoms typically worsen significantly during stressful periods and may improve when stress decreases.
What If You Have Both?
Here's an important reality: ADHD and anxiety frequently occur together. Studies show that about 50% of adults with ADHD also have an anxiety disorder.
This makes sense when you think about it. Living with undiagnosed or untreated ADHD is stressful. Constantly forgetting things, missing deadlines, struggling to keep up, and feeling like you're failing at "basic" tasks that seem easy for everyone else creates chronic stress that can develop into anxiety.
Additionally, both conditions involve difficulties with emotional regulation, which can make you more vulnerable to anxiety when you have ADHD
Why Diagnosing Both Matters
When you have both ADHD and anxiety, treatment needs to address both conditions. Taking ADHD medication might improve your focus and organization, which then reduces the anxiety that came from struggling with those things. But if you also have an underlying anxiety disorder, you might need anxiety treatment as well.
Conversely, treating only the anxiety might help you feel calmer but won't address the core ADHD symptoms affecting your executive function and attention.
This is why comprehensive evaluation is so important.
Other Conditions That Can Look Like ADHD or Anxiety
Before settling on a diagnosis, it's important to rule out other conditions that can mimic ADHD or anxiety:
Depression: Can cause concentration problems, fatigue, and difficulty completing tasks. Learn about the differences in our guide to mental health services.
Bipolar disorder: Can involve racing thoughts, difficulty concentrating, and impulsivity during manic or hypomanic episodes.
Sleep disorders: Chronic sleep deprivation causes attention problems, irritability, and difficulty with executive function.
Thyroid problems: Both hyperthyroidism and hypothyroidism can affect concentration, energy, and mood.
Trauma: Can cause hypervigilance, difficulty concentrating, and emotional dysregulation.
Substance use: Caffeine, alcohol, or other substances can create or worsen symptoms that look like ADHD or anxiety.
This is why professional evaluation matters. Self-diagnosis based on symptom lists often misses the bigger picture.
Getting an Accurate Diagnosis
If you're wondering whether you have ADHD, anxiety, or both, here's how to get clarity:
Comprehensive Evaluation
At Harborside Psychiatry, our comprehensive diagnostic testing process includes:
Detailed clinical interview: We ask about your current symptoms, when they started, how they affect different areas of your life, and your developmental history.
Childhood history: For ADHD diagnosis, we need to understand whether symptoms were present before age 12. We'll ask about school performance, behavior reports, and how you functioned as a child.
Symptom patterns: We look at whether symptoms are consistent across situations or context-dependent, what triggers them, and how they've changed over time.
Screening for other conditions: We assess for depression, bipolar disorder, trauma history, substance use, and medical conditions that could explain symptoms.
Functional assessment: How are symptoms actually impacting your work, relationships, daily tasks, and quality of life?
Why Professional Diagnosis Matters
Online quizzes and self-assessment tools can be a starting point, but they can't replace professional evaluation. Here's why:
Overlapping symptoms: As we've discussed, ADHD and anxiety share many symptoms. A professional can tease apart the differences.
Comorbidity: Many people have both conditions or have ADHD plus depression or other issues. A comprehensive evaluation catches everything.
Treatment implications: The wrong diagnosis leads to the wrong treatment, which wastes time and can make things worse.
Childhood history: Adults often struggle to accurately remember and interpret their childhood symptoms. A trained professional knows what questions to ask and how to interpret the answers.
Our psychiatric mental health nurse practitioners at Harborside provide thorough evaluations to ensure you get an accurate diagnosis, not a rushed assessment based on a quick symptom checklist.
Treatment Differences: Why Diagnosis Matters
Getting the right diagnosis is crucial because ADHD and anxiety require different treatment approaches:
ADHD Treatment
Medication: Stimulant medications (like Adderall, Vyvanse, Ritalin) or non-stimulant options (like Strattera, Wellbutrin) are often first-line treatments. These medications increase dopamine and norepinephrine to improve attention and executive function.
Therapy: Focuses on developing organizational systems, time management strategies, and coping with emotional dysregulation.
Lifestyle: Exercise, adequate sleep, routine/structure, and minimizing distractions.
Learn more about our approach to ADHD treatment.
Anxiety Treatment
Medication: SSRIs or SNRIs are common first-line medications. These are very different from ADHD medications and work by increasing serotonin.
Therapy: Cognitive-behavioral therapy (CBT) to challenge anxious thoughts, exposure therapy for specific fears, and relaxation techniques.
Lifestyle: Stress management, sleep hygiene, reducing caffeine, and regular exercise.
Explore our anxiety treatment options.
When You Have Both
Treatment becomes more nuanced. Sometimes treating ADHD first reduces secondary anxiety. Other times, both conditions need simultaneous treatment. The approach depends on which symptoms are most impairing and how the conditions interact in your specific case.
At Harborside Psychiatry, our integrative approach combines medication management with therapy and lifestyle modifications to address both conditions effectively. Our psychiatric mental health nurse practitioners provide both medication and therapeutic support in one place, ensuring coordinated care.

What to Do If You're Still Unsure
If you're reading this and still can't tell whether your symptoms point to ADHD, anxiety, or both, that's completely normal. This is exactly why professional evaluation exists.
Here are your next steps:
Keep a symptom journal: For a week or two, note when symptoms occur, what you're doing, what you're thinking about, and how it affects you. This helps identify patterns.
Reflect on your childhood: Talk to parents or look at old report cards. What did teachers say about you? How did you do with homework, organization, and sitting still?
Consider what's changed: Did symptoms appear during a stressful period, or have they been present as long as you remember? Do they fluctuate or stay consistent?
Schedule an evaluation: Bring your observations to a mental health professional who can conduct a thorough assessment.
At Harborside Psychiatry, we treat patients ages 6 to 65 throughout Oregon via telehealth. Whether you're an adult finally seeking answers for lifelong struggles, a parent concerned about your child, or somewhere in between, we can help you get clarity.
FAQs About ADHD vs. Anxiety
Can anxiety cause ADHD-like symptoms?
Yes. Severe anxiety can cause concentration problems, restlessness, and difficulty completing tasks that look similar to ADHD. However, these symptoms are driven by worry and typically improve when anxiety is treated. True ADHD symptoms are present regardless of anxiety levels.
Can ADHD medication make anxiety worse?
Sometimes. Stimulant medications can increase heart rate and physical arousal, which some people with anxiety find uncomfortable. However, for many people, treating ADHD actually reduces anxiety because they're no longer stressed about constantly forgetting things and struggling to keep up. Your provider can adjust medication if anxiety worsens.
Can you develop ADHD as an adult?
No. By definition, ADHD must have been present before age 12. However, you can have had ADHD all along without recognizing it until adulthood. Many adults, especially women, are diagnosed later in life when demands increase or coping strategies stop working. What feels like "developing ADHD" is usually unmasking symptoms that were always there.
How long does it take to get diagnosed?
A comprehensive ADHD evaluation typically takes 1-2 appointments. The initial assessment is usually 60-90 minutes, and sometimes a follow-up is needed to gather additional information or clarify findings. At Harborside, we don't rush the process because accurate diagnosis matters.
Do I need to be tested by a psychologist for ADHD?
Not necessarily. While psychologists can provide comprehensive psychological testing, psychiatric nurse practitioners and psychiatrists can also diagnose ADHD through clinical evaluation. Formal psychological testing is helpful when the diagnosis is unclear or when learning disabilities might also be present.
What if I have ADHD but don't want to take medication?
Medication isn't mandatory, though it's often the most effective treatment for ADHD. You can try therapy, coaching, and lifestyle strategies first. However, many people find that medication makes other interventions more accessible by improving their ability to focus and follow through.
