ADHD vs. Anxiety: How Can You Tell the Difference? | Round Rock, TX

By Mary Parker, LPC-S

“I cannot focus” is not a diagnosis.

Difficulty concentrating can show up with ADHD, anxiety, depression, sleep deprivation, trauma, stress, medical conditions, medication effects, and more. ADHD and anxiety can also occur together, which is one reason a five-minute online checklist cannot always tell you what is happening.

Why ADHD and Anxiety Can Look So Similar

Both can involve restlessness, procrastination, difficulty concentrating, irritability, sleep problems, and feeling overwhelmed. Research has also found that common self-report measures can have limited specificity when clinicians are trying to distinguish adult ADHD from anxiety.

The question is not simply which symptom you have. The pattern, history, triggers, and function of the symptom matter.

What Does the Attention Problem Feel Like?

With ADHD, attention problems are often broad and longstanding. A person may lose track of routine tasks, underestimate time, forget instructions, struggle to start low-interest work, or become intensely absorbed in highly engaging activities.

With anxiety, concentration may be disrupted because mental resources are being consumed by worry, threat monitoring, rumination, or physical arousal.

That distinction is not perfect, and people can have both.

History Matters

ADHD is a neurodevelopmental disorder, so clinicians look for evidence that relevant symptoms were present earlier in life rather than appearing for the first time during a stressful adult period.

Anxiety can also begin early, but understanding when the difficulties started and what was happening around them helps with differential diagnosis.

Ask: What Happens When the Anxiety Is Quiet?

This can be a useful clinical question. If anxiety improves, do the problems with organization, time, working memory, task initiation, and impulsivity remain?

Conversely, if the person is able to organize and focus when they are not worried but concentration falls apart primarily during anxious periods, that is useful information too.

It is not a do-it-yourself diagnostic test. It is one piece of the story.

ADHD and Anxiety Frequently Coexist

A 2025 review emphasized that anxiety and depressive disorders commonly coexist with adult ADHD. Recent meta-analytic work also reports higher anxiety symptom levels in adults with ADHD than in comparison groups. So the answer is often not ADHD or anxiety. Sometimes it is ADHD and anxiety.

Why the Distinction Matters for Counseling

If avoidance is driven primarily by fear, treatment may need to address the fear and avoidance pattern. If the problem is executive-function friction, the person may need external systems, environmental changes, task-initiation strategies, and ADHD-informed skills. If both are present, the plan should account for both.

For anxiety disorders, evidence-based counseling may include cognitive and behavioral strategies and, when appropriate, exposure-based work. ADHD-focused counseling may emphasize executive-function support, emotional regulation, communication, and practical systems.

Do Not Let Shame Make the Diagnosis for You

People often arrive saying, “I am just lazy,” “I am too much,” or “I should be able to handle this.” Those are judgments, not assessments.

A better process looks at patterns over time, impairment across settings, co-occurring symptoms, developmental history, and other possible explanations.

Frequently Asked Questions

Can anxiety cause ADHD?

Anxiety does not cause the neurodevelopmental disorder ADHD, but anxiety can create concentration and restlessness symptoms that overlap with ADHD, and the two conditions can coexist.

Can ADHD make anxiety worse?

ADHD-related missed deadlines, disorganization, impulsive mistakes, or repeated negative feedback can create additional stress and anxiety. Comorbid anxiety also occurs commonly in people with ADHD.

Can a questionnaire tell me which one I have?

Screening tools can provide useful information, but research shows symptom overlap can limit their ability to make a differential diagnosis by themselves.
