Key Takeaways
- ADHD often co-occurs with anxiety and other conditions, which can make diagnosis and treatment more difficult.
- Difficulty focusing alone cannot establish whether ADHD, anxiety, or another explanation is involved.
- Assessment considers symptoms, functioning, history, and other possible explanations.
- Adults with ADHD may receive psychotherapy, medication, or a combination, depending on clinical assessment.
- Persistent anxiety that interferes with daily life should be discussed with a healthcare professional.
How ADHD and anxiety can occur together
ADHD and anxiety are different clinical concerns, but they can appear together. NIMH notes that ADHD often co-occurs with anxiety and other conditions. When more than one problem is present, diagnosis and treatment may become more difficult because the same everyday complaint—such as trouble concentrating—may not point to one explanation by itself.
This is why a person searching for “ADHD or anxiety symptoms” should be cautious about relying on online checklists. A checklist may help someone describe what has been happening, but it cannot establish a diagnosis. The more useful questions are how symptoms affect functioning, how long they have been present, and what other explanations need to be considered.
Why ADHD and anxiety may occur together
The verified clinical information supports the fact that these conditions commonly co-occur, but it does not establish one universal reason why this happens. There is no single explanation that applies to everyone with both ADHD and anxiety.
For some people, attention or functioning difficulties may exist alongside anxiety symptoms. For others, anxiety may be the main concern, with concentration becoming difficult in that context. A person may also have both conditions independently. The practical consequence is the same: assessment needs to consider the whole pattern rather than assuming that one condition automatically caused the other.
The presence of one condition can also make the other harder to recognise. If attention-related difficulties and anxiety are discussed separately, important parts of the person’s history may be missed. NIMH therefore describes ADHD assessment as considering symptoms, functioning, history, and other possible explanations—not relying on one symptom or a single checklist.
Why ADHD and anxiety symptoms can be difficult to distinguish
People commonly ask whether concentration problems mean ADHD or anxiety. That question cannot be answered from this symptom alone. A professional assessment is needed to examine the broader pattern and the effect on daily life.
When difficulty focusing should be assessed
Difficulty focusing is worth discussing when it is persistent, troubling, or interfering with ordinary responsibilities. The same principle applies when worry or anxiety symptoms begin to affect daily life. Rather than trying to label the cause independently, a person can bring a clear description of what they notice to a healthcare professional.
Useful details include the symptoms that are most disruptive, the situations in which they occur, their effect on functioning, and relevant personal history. These details do not diagnose ADHD or anxiety, but they can help the clinician consider the symptoms and possible explanations in context.
How ADHD and anxiety are assessed
ADHD assessment is not based on one symptom or a quick score. According to NIMH, it considers symptoms, functioning, history, and other possible explanations. This approach matters when anxiety is also present because the clinician needs to assess co-occurring conditions rather than focusing narrowly on attention.
Someone who wants to know how to get diagnosed with ADHD as an adult may find it helpful to prepare examples of the problems they are experiencing. The assessment itself remains a clinical process. Personal notes can support the conversation, but they are not a substitute for professional evaluation.
Anxiety symptoms that persist and interfere with daily life should also be discussed with a healthcare professional. NIMH states that a clinician can assess anxiety and co-occurring conditions. This is particularly relevant when a person is unsure whether concentration problems, worry, or both are affecting their functioning.

Treatment options when ADHD and anxiety occur together
There is no single treatment plan for everyone with ADHD and anxiety. Treatment choices depend on clinical assessment, including which symptoms are present and how they affect functioning.
For adults with ADHD, NIMH identifies psychotherapy such as behavioral therapy or cognitive behavioral therapy, medication, or a combination as possible approaches. These options are not a recommendation for a particular individual. A healthcare professional needs to consider the person’s assessment and co-occurring conditions before discussing suitable care.
When ADHD and anxiety are both suspected, it is helpful to tell the clinician about both rather than presenting only the concentration problem or only the worry. A fuller description may help the professional consider both conditions and avoid assessing an incomplete picture.
People who want to understand medication decisions can read our guide to ADHD medications, including stimulants versus non-stimulants. The choice to use medication, and how it fits with psychotherapy or other care, should be discussed with the prescribing clinician. This article does not provide dosage advice, and medication should not be started, stopped, or changed without professional guidance.
What is known about ADHD treatment and anxiety symptoms
The verified sources do not establish that treating ADHD will reduce anxiety for everyone. They do support the use of psychotherapy, medication, or a combination for adults with ADHD, depending on clinical assessment. If anxiety symptoms are also present, they should be raised during the assessment so the clinician can consider co-occurring conditions.
Similarly, a person should not assume that addressing anxiety alone will explain every attention or functioning difficulty. Persistent problems deserve a broader discussion, particularly when they affect work, study, relationships, or other ordinary activities.
When to Seek Care
When emergency care is needed
Call emergency services or your local emergency number immediately if there is an immediate danger to life or safety. This article cannot assess emergencies remotely.
When urgent professional help is appropriate
Seek urgent professional help when anxiety symptoms are interfering substantially with daily life or when symptoms feel difficult to manage safely. A healthcare professional can assess anxiety and possible co-occurring conditions.
When to arrange a routine appointment
Arrange a routine appointment when attention problems, anxiety symptoms, or both persist and affect functioning. Bring examples of the symptoms, their impact, relevant history, and any concerns about possible explanations. This gives the clinician useful context for an assessment.
Preparing for an appointment
Practical preparation can make a healthcare conversation more productive. Write down the main symptoms you notice and the ways they affect functioning. Include both attention-related concerns and anxiety symptoms instead of choosing one label in advance.
Keep a simple record of when difficulties occur and which situations seem most disruptive. The purpose is not to score yourself or reach a diagnosis. It is to create a clearer history for the professional assessing you.
Use reminders to prepare questions for an appointment, such as: Could anxiety and ADHD both be relevant? What other explanations should be considered? What information would help assess functioning and history? These questions can keep the discussion focused without turning self-screening into self-diagnosis.
Finally, avoid changing prescribed treatment on your own. Adults with ADHD may receive psychotherapy, medication, or both depending on clinical assessment, so treatment decisions belong in a conversation with a qualified healthcare professional. If anxiety remains persistent or interferes with daily life, mention it directly rather than assuming it is simply part of ADHD.
