ADHD and Anxiety: What’s the Difference, and Can You Have Both?

Have you ever sat down to finish an important task, only to find your mind jumping between unfinished work, worries about the future, and everything you might be forgetting? Perhaps you struggle to concentrate, feel restless, or spend hours overthinking even the smallest decisions.

These experiences can happen with attention-deficit/hyperactivity disorder (ADHD), anxiety, or both.

Although ADHD and anxiety share some symptoms, they are different conditions. ADHD primarily affects attention, impulse control, and the ability to manage everyday tasks. Anxiety involves excessive worry, fear, or nervousness that can interfere with daily life.

The confusing part is that one condition can sometimes make the other harder to manage. For example, difficulties with time management caused by ADHD may lead to ongoing stress, while anxiety can make it even harder to concentrate or get things done.

So, how can you tell the difference between ADHD and anxiety in adults? And what should you do if you think you might have both?

Let’s explore their symptoms, key differences, diagnosis, and treatment options in simple terms.

What Is the Difference Between ADHD and Anxiety?

The main difference between ADHD and anxiety is the pattern behind your symptoms.

ADHD is a neurodevelopmental condition that usually begins in childhood, even when it isn’t recognized until adulthood. It can affect your ability to pay attention, organize tasks, manage time, control impulses, and follow through on responsibilities.

Anxiety can be a normal stress response. However, when excessive worry or fear becomes persistent and interferes with everyday activities, it may indicate an anxiety disorder.

Here’s a quick comparison:

These differences are useful clues, not strict rules. ADHD can involve anxiety, and anxiety can occur alongside attention difficulties for several reasons. A professional evaluation is needed to understand what’s happening in your particular situation.

What Are the Symptoms of ADHD in Adults?

ADHD doesn’t look the same in everyone. Some adults mainly struggle with inattention, while others experience hyperactivity and impulsivity. Many experience a combination of these symptoms.

Common signs of adult ADHD include:

1. Difficulty concentrating

You might start reading an email, notice a notification, open another tab, and forget what you were doing in the first place.

You may also find it difficult to stay focused during long meetings, finish paperwork, or complete tasks that feel repetitive or uninteresting.

2. Forgetfulness and disorganization

Adults with ADHD may frequently misplace their keys, forget appointments, miss deadlines, or struggle to keep track of everyday responsibilities.

You might know exactly what needs to be done but have trouble organizing the steps required to finish it.

3. Procrastination and difficulty getting started

Sometimes, even a simple task can feel unusually difficult to begin. You may delay starting a project despite knowing it is important.

This can happen when organizing, prioritizing, or breaking a task into manageable steps becomes challenging. It isn’t necessarily laziness or a lack of motivation.

4. Restlessness and impulsivity

Hyperactivity in adults doesn’t always look like running around or constantly moving. It may feel like an inability to relax, frequent fidgeting, excessive talking, or a constant need to stay occupied.

Impulsivity can involve interrupting others, making quick decisions, or spending money without fully considering the consequences.

5. Difficulty managing everyday responsibilities

You might struggle to balance work, household tasks, relationships, and personal commitments. Even when you’re trying hard, keeping everything organized can feel exhausting.

These difficulties may also lead to frustration, embarrassment, or worry about falling behind.

Remember, experiencing some of these symptoms does not automatically mean you have ADHD. The symptoms must fit a broader pattern, affect daily functioning, and meet the criteria for a clinical diagnosis.

What Are the Symptoms of Anxiety in Adults?

Anxiety can affect both your thoughts and your body. Everyone experiences worry occasionally, but an anxiety disorder involves symptoms that are persistent, excessive, difficult to control, or disruptive to everyday life.

Common symptoms include:

1. Constant worrying

You might repeatedly think about whether you made a mistake at work, whether something bad will happen to a loved one, or whether you can handle an upcoming responsibility.

Even after someone reassures you, the worry may return.

2. Racing or repetitive thoughts

Your mind may keep revisiting the same concern, imagining negative outcomes, or trying to find certainty about something you cannot fully control.

Unlike the shifting attention that can occur with ADHD, anxiety-related thoughts often revolve around worries, fears, or possible threats.

3. Physical tension and restlessness

Anxiety can cause muscle tension, a racing heart, sweating, trembling, stomach discomfort, or a feeling of being constantly on edge.

Some people also experience panic attacks, which can involve sudden, intense fear and physical symptoms.

4. Avoiding situations that feel overwhelming

You might avoid a meeting because you’re afraid of being judged, delay making a phone call because you fear a negative response, or turn down social invitations because you worry something will go wrong.

Avoidance may provide temporary relief, but it can make certain fears harder to manage over time.

5. Sleep and concentration problems

When your mind keeps worrying about tomorrow, falling asleep can become difficult. Poor sleep may then leave you tired, irritable, and less able to concentrate the following day.

The National Institute of Mental Health (NIMH) describes excessive fear and worry, along with related physical and behavioral symptoms, as important features of anxiety disorders.

ADHD vs. Anxiety: How Can You Tell Them Apart?

Because ADHD and anxiety share symptoms, looking at one symptom in isolation usually isn’t enough. The more useful question is what happens around that symptom, how long it has been present, and how it affects your daily life.

ADHD-related inattention vs. anxiety-related inattention

Imagine two people who both struggle to finish a work assignment.

The first person starts the assignment but keeps switching between emails, unrelated tasks, and other distractions. They may lose track of time and struggle to return to the original task, even when they aren’t particularly worried.

The second person wants to finish the assignment but keeps thinking, “What if I make a mistake?” or “What if my manager thinks I’m not good enough?” Their attention repeatedly shifts toward these worries.

Both people may appear distracted from the outside, but the experiences behind the difficulty can be different.

This distinction isn’t absolute. Someone with ADHD may become anxious about a deadline, and someone with anxiety may become distracted for reasons that have nothing to do with a specific worry.

ADHD restlessness vs. anxiety-related restlessness

With ADHD, restlessness may show up as frequent movement, fidgeting, impatience, or difficulty remaining engaged in activities that require sustained attention.

With anxiety, restlessness may feel more like physical tension, nervous anticipation, or an inability to relax because something seems wrong.

However, these experiences can overlap, particularly when someone has both conditions.

ADHD forgetfulness vs. anxiety-related forgetfulness

An adult with ADHD may regularly forget appointments, lose personal belongings, or miss important details because of difficulties with attention, organization, and remembering intentions.

An anxious adult may also forget information, especially when their attention is consumed by worry or when they aren’t sleeping well.

The difference often becomes clearer when a professional looks at the person’s longer-term history and the situations in which the difficulties occur.

ADHD impulsivity vs. anxiety-driven avoidance

ADHD may involve acting before thinking through the consequences, interrupting conversations, or making spontaneous decisions.

Anxiety more commonly involves hesitation, repeatedly checking decisions, seeking reassurance, or avoiding situations because of feared outcomes.

Neither pattern applies to everyone, and impulsivity or avoidance can have causes beyond these two conditions.

Can You Have ADHD and Anxiety at the Same Time?

Yes. It is possible to have both ADHD and an anxiety disorder.

Having one condition does not rule out the other. In fact, research has found an association between ADHD and increased anxiety symptoms in adults, which is one reason clinicians should consider both when assessing someone who has concentration problems or persistent worry.

When the conditions occur together, it can sometimes be difficult to identify which symptoms belong to which condition.

For example, imagine an adult who struggles with ADHD-related time management. They regularly underestimate how long tasks will take, arrive late to appointments, and leave important work until the last minute.

After repeated stressful experiences, they begin worrying constantly about being late, making mistakes, or disappointing others. Eventually, the worry becomes difficult to control, even when there isn’t an immediate deadline.

In this situation, ADHD-related challenges and anxiety may both need attention.

It is also possible for anxiety to occur independently of ADHD. A person who has always managed their attention well but develops persistent worry after a stressful period may have a different underlying problem.

The important thing is not to assume that every anxious feeling comes from ADHD or that every concentration problem is caused by anxiety.

Does ADHD Cause Anxiety?

ADHD does not automatically cause an anxiety disorder. However, living with unmanaged ADHD can contribute to stress and worry for some people.

Consider a few common situations:

• Repeated missed deadlines: You worry that your manager will become frustrated because you struggle to estimate how long assignments will take.
• Forgetfulness: You become anxious about missing appointments, losing important documents, or forgetting responsibilities.
• Relationship difficulties: You worry about being misunderstood when you interrupt conversations, forget plans, or struggle to follow through on commitments.
• Fear of making mistakes: After receiving repeated criticism, you begin expecting negative feedback even when you are trying your best.
• Overthinking everyday responsibilities: You spend so much time worrying about what you’ve forgotten that it becomes harder to focus on what you’re doing now.

These experiences can create a cycle in which attention difficulties contribute to stress, and stress makes it harder to concentrate or manage responsibilities.

However, anxiety can also develop for other reasons, including genetics, life experiences, and other health or psychological factors.

Can Anxiety Make ADHD Symptoms Worse?

Anxiety can make existing attention and organizational difficulties harder to manage.

When you’re worried, some of your mental energy goes toward monitoring potential problems, anticipating negative outcomes, or trying to feel certain about a situation.

This can leave you with less attention available for the task in front of you.

For example, you may already struggle to start a complicated assignment because of ADHD. If anxiety adds a fear of failure, you might spend even longer avoiding the task, repeatedly checking your work, or worrying about where to begin.

Poor sleep caused by anxiety may also make concentration, patience, and emotional regulation more difficult.

This does not mean anxiety always worsens ADHD or that every increase in ADHD symptoms is caused by anxiety. The relationship varies from person to person.

Understanding how the two conditions interact can help a clinician develop a treatment plan that addresses the actual difficulties you’re experiencing.

How Is ADHD Diagnosed When Anxiety Is Also Present?

There is no single symptom or online questionnaire that can reliably determine whether you have ADHD, an anxiety disorder, or both.

A qualified healthcare professional will usually consider your symptoms, personal history, and how your difficulties affect your daily life.

An ADHD assessment may explore:

• Whether relevant symptoms were present during childhood.
• How symptoms affect work, education, relationships, and everyday responsibilities.
• Whether difficulties occur in more than one setting.
• Whether other conditions or circumstances could explain the symptoms.

An anxiety assessment may explore the nature of your worries, their frequency and intensity, physical symptoms, avoidance behaviors, and their impact on daily functioning.

The clinician may also consider sleep difficulties, depression, trauma, medication effects, or other possible explanations for your symptoms.

If you’re unsure what to expect, our guide to how ADHD is diagnosed in adults explains the assessment process in more detail.

Why childhood history matters

ADHD is a neurodevelopmental condition, so evidence of several symptoms before age 12 is an important part of diagnosis.

Adults are not always able to remember their childhood clearly. School reports, family observations, or other available information may sometimes help clarify the history.

Anxiety can begin at different stages of life. A professional will therefore consider when each difficulty began, whether it has persisted, and how it relates to the person’s experiences.

The American Psychiatric Association’s diagnostic framework emphasizes assessing the full pattern of symptoms and their impact rather than relying on a single complaint.

A careful evaluation helps reduce the risk of overlooking one condition while focusing on the other.

What Is the Treatment for ADHD and Anxiety?

Treatment depends on your symptoms, how much they interfere with daily life, your health history, and whether you have one condition or both.

There is no single treatment that works for everyone. A clinician can help you decide which approaches are appropriate for your situation.

Treatment for ADHD

ADHD treatment may include medication, psychotherapy, practical coping strategies, or a combination of approaches. For a more detailed look at available treatment approaches, read our guide to Treatment for ADHD in Adults.

Medication: Stimulant and non-stimulant medications may help manage core ADHD symptoms. A qualified prescriber can discuss potential benefits, side effects, and monitoring requirements.

Cognitive behavioral therapy (CBT): CBT adapted for ADHD can help people develop strategies for managing time, breaking down tasks, improving organization, and responding to unhelpful thought patterns.

Practical support: Using reminders, calendars, written instructions, routines, and smaller task steps may help make everyday responsibilities more manageable.

Treatment for anxiety

Treatment for anxiety may involve psychotherapy, medication, or both.

Cognitive behavioral therapy: CBT can help people recognize unhelpful thinking patterns, understand how worry affects behavior, and develop healthier ways to respond to feared situations.

Medication: Depending on the type and severity of anxiety, a healthcare professional may discuss medications such as selective serotonin reuptake inhibitors (SSRIs) or other appropriate options.

Stress-management strategies: Relaxation exercises, regular sleep routines, physical activity, and reducing avoidant behaviors may support treatment, although they are not substitutes for professional care when an anxiety disorder is present.

What if you have both ADHD and anxiety?

When both conditions are present, treatment should consider each one rather than assuming that treating one will resolve everything.

For example, improving ADHD-related organization may reduce some deadline-related stress. However, persistent anxiety may still require its own treatment.

Medication decisions can also require careful consideration. Some people experience increased jitteriness or anxiety with certain ADHD medications, while others tolerate them well. Medication should be selected and monitored by a qualified prescriber rather than changed or stopped without medical guidance.

A personalized treatment plan can help identify which symptoms need the most attention and how different approaches may work together.

When Should You Seek Professional Help?

Consider seeking professional support if concentration difficulties, persistent worry, restlessness, or related symptoms regularly interfere with your work, relationships, sleep, or everyday responsibilities.

You do not need to be certain whether ADHD or anxiety is responsible before asking for help.

It may be useful to write down:

• The symptoms you experience most often.
• When you first noticed them.
• Situations in which they become better or worse.
• How they affect your work, relationships, and daily routine.
• Any sleep difficulties, medications, or other health concerns.

These details can help a clinician understand your experience and decide what assessment may be appropriate.

If you experience severe chest pain, serious difficulty breathing, fainting, or new or unusual physical symptoms, seek urgent medical assessment rather than assuming they are caused by anxiety.

If you are struggling emotionally, support is available. You can explore Divine Health Psychotherapy to learn more about the mental health services and professional support offered.

Final Thoughts

ADHD and anxiety can look similar on the surface, especially when both affect concentration, restlessness, sleep, or the ability to complete everyday tasks.

One useful distinction is that ADHD often involves a longer-standing pattern of attention, organization, and impulse-control difficulties, while anxiety involves excessive worry or fear. But these patterns are not always easy to separate, and both conditions can occur together.

You don’t have to work out the answer on your own. A thorough professional evaluation can help you understand your symptoms and identify treatment options that fit your needs.

With the right support, it is possible to develop more effective ways to manage daily responsibilities, reduce distress, and improve your quality of life.
