Yes, anxiety and ADHD can occur together, and recognizing the overlap can be important when symptoms such as difficulty concentrating, restlessness, forgetfulness, racing thoughts, procrastination, or feeling overwhelmed affect everyday life.
ADHD and anxiety are different conditions, but they can share several symptoms. For example, someone with anxiety may have difficulty concentrating because their attention is occupied by persistent worry. Someone with ADHD may struggle to concentrate because of distractibility, executive-function difficulties, or difficulty maintaining attention.
This overlap can make it challenging to understand what is actually happening.
The Centers for Disease Control and Prevention (CDC) recognizes anxiety as one of the conditions that can occur alongside ADHD and notes that other conditions should be considered when evaluating ADHD symptoms. CDC information on ADHD and co-occurring conditions
The National Institute of Mental Health (NIMH) also explains that ADHD can coexist with other mental disorders and that a comprehensive assessment can help distinguish ADHD from anxiety, depression, sleep problems, and other conditions. NIMH ADHD information
Understanding the differences can help people seek appropriate support rather than assuming that every concentration problem is ADHD or every restless thought is anxiety.
What Is ADHD?
Attention-deficit/hyperactivity disorder, commonly called ADHD, is a developmental disorder involving persistent patterns of inattention, hyperactivity, and/or impulsivity.
ADHD can affect children, teenagers, and adults.
Common symptoms may include:
- Difficulty sustaining attention
- Easily becoming distracted
- Forgetting appointments or responsibilities
- Losing things frequently
- Difficulty organizing tasks
- Procrastination
- Trouble completing projects
- Restlessness
- Excessive talking
- Interrupting others
- Acting without thinking
- Difficulty managing time
- Problems planning and prioritizing
For ADHD to be diagnosed, symptoms need to be persistent, occur in more than one setting, and interfere with functioning. NIMH explains that ADHD symptoms begin during childhood, although some people are not diagnosed until adulthood. NIMH ADHD diagnosis and treatment information
What Is Anxiety?
Anxiety is a normal response to uncertainty, danger, or stressful situations. Everyone experiences occasional worry.
An anxiety disorder is different. Anxiety disorders involve excessive or persistent fear, worry, or nervousness that interferes with everyday activities.
Depending on the specific anxiety disorder, symptoms may include:
- Excessive worrying
- Feeling constantly on edge
- Restlessness
- Difficulty relaxing
- Racing thoughts
- Difficulty concentrating
- Sleep difficulties
- Muscle tension
- Fatigue
- Irritability
- Rapid heartbeat
- Sweating
- Trembling
- Stomach discomfort
NIMH explains that generalized anxiety disorder can involve persistent worry, difficulty controlling worry, restlessness, concentration problems, sleep difficulties, fatigue, and physical symptoms such as headaches and muscle aches. NIMH information on generalized anxiety disorder
For readers interested in how anxiety can influence thinking, Global Health Martz also covers anxiety and cognitive distortions, including the way fear can affect interpretation and decision-making.
How Can Anxiety and ADHD Overlap?
The most confusing aspect of having ADHD and anxiety together is that some symptoms can look remarkably similar.
1. Difficulty Concentrating
Both conditions can affect concentration, but the underlying reasons may be different.
With ADHD, a person may become distracted by sounds, thoughts, surroundings, notifications, or unrelated tasks. They may struggle to sustain attention even when they genuinely want to focus.
With anxiety, concentration may be disrupted because the mind is occupied with worry.
For example:
ADHD:
“I started working, noticed a notification, opened another task, and completely forgot what I was doing.”
Anxiety:
“I was trying to work, but I kept thinking about everything that could go wrong.”
A person can experience both patterns simultaneously.
2. Restlessness
Restlessness is another overlapping symptom.
Someone with ADHD may feel an ongoing need for movement or stimulation. They may fidget, shift between tasks, or find it difficult to remain still for long periods.
Someone with anxiety may feel physically restless because their body remains in a state of heightened alertness.
NIMH lists restlessness among potential symptoms of generalized anxiety disorder and also describes restlessness or excessive activity among ADHD symptoms. NIMH anxiety information
The difference becomes clearer when a healthcare professional examines the person’s broader history and symptom pattern.
3. Racing Thoughts
People often describe both anxiety and ADHD as involving a “busy mind,” but the experience may be different.
With anxiety, thoughts may repeatedly focus on possible threats:
- What if something goes wrong?
- Did I make a mistake?
- What will happen tomorrow?
- What if someone is upset with me?
With ADHD, thoughts may jump rapidly between unrelated subjects, ideas, tasks, memories, or interests.
When both conditions occur, these patterns can combine.
A person may begin worrying about an upcoming meeting, become distracted by another thought, remember an unfinished task, worry about being late, and then become overwhelmed by everything that needs to be completed.
4. Procrastination and Avoidance
Procrastination can occur with both anxiety and ADHD.
Someone with ADHD may postpone a task because:
- It feels boring
- It feels overwhelming
- They do not know where to start
- They underestimate how long it will take
- They become distracted
- They have difficulty organizing the steps
Anxiety can produce procrastination because the task creates fear or uncertainty.
For example:
“I don’t know how to do this perfectly, so I keep avoiding it.”
The same behavior—avoiding a task—can therefore have different underlying causes.
ADHD and Anxiety: What Are the Main Differences?
Although symptoms overlap, there are some useful differences.
| Symptom | ADHD | Anxiety |
|---|---|---|
| Difficulty concentrating | Often related to distractibility or attention regulation | Often related to excessive worry |
| Restlessness | May reflect stimulation needs or hyperactivity | May reflect nervousness or heightened alertness |
| Forgetfulness | Often associated with executive-function difficulties | Can occur when attention is consumed by worry |
| Procrastination | May involve task initiation or organization difficulties | May involve fear, uncertainty, or perfectionism |
| Racing thoughts | Thoughts may shift quickly between subjects | Thoughts often revolve around worries or threats |
| Sleep problems | Can occur frequently | Can result from worry or physical tension |
| Impulsivity | Can be a core ADHD symptom | Not a defining anxiety symptom |
| Excessive worry | Not a core ADHD symptom | A central feature of many anxiety disorders |
These differences are useful for understanding symptoms but are not enough to diagnose either condition.
Can Anxiety Make ADHD Symptoms Feel Worse?
Yes. Anxiety can make existing attention and executive-function difficulties more difficult to manage.
Imagine someone with ADHD who already struggles with planning.
They receive several work assignments.
Instead of organizing them into manageable steps, they begin worrying:
- “What if I miss something?”
- “What if I disappoint my manager?”
- “What if I cannot finish everything?”
The worry consumes additional mental attention.
As anxiety increases, the person may become even less productive, which creates another reason to worry.
This can produce a cycle:
ADHD difficulties → unfinished tasks → anxiety → reduced concentration → more unfinished tasks → greater anxiety.
This does not mean anxiety causes ADHD. Instead, the two conditions can interact and amplify everyday difficulties.
Can ADHD Increase Anxiety?
ADHD and anxiety are separate conditions, but repeated difficulties associated with ADHD can contribute to stressful experiences.
For example, a person may repeatedly:
- Miss deadlines
- Forget appointments
- Lose important items
- Arrive late
- Leave tasks unfinished
- Interrupt people unintentionally
- Struggle with organization
- Receive criticism at school or work
After repeated experiences, someone may begin worrying about making another mistake.
That worry may eventually become a separate problem requiring attention.
The CDC recognizes anxiety as a condition that can coexist with ADHD. CDC ADHD and co-occurring conditions
How Sleep Can Affect ADHD and Anxiety
Sleep is another important part of the picture.
Poor sleep can make concentration, emotional regulation, energy, and daily functioning more difficult. NIMH notes that sleep problems can occur in people with ADHD. NIMH ADHD information
Anxiety can also interfere with falling asleep or staying asleep.
This may create another cycle:
Anxiety → poor sleep → reduced concentration → greater difficulty managing ADHD symptoms → more stress → increased anxiety.
Global Health Martz explores this relationship in its article on anxiety and sleep, which can provide additional educational context.
If sleep difficulties are persistent, it is important to investigate the underlying cause rather than assuming they are simply part of ADHD or anxiety.
Physical Symptoms When ADHD and Anxiety Occur Together
The combination of anxiety and ADHD can sometimes be physically exhausting.
Anxiety may be associated with:
- Muscle tension
- Headaches
- Fatigue
- Trembling
- Sweating
- Stomach discomfort
- Rapid heartbeat
NIMH lists muscle aches, headaches, trembling, and fatigue among possible physical symptoms associated with generalized anxiety disorder. NIMH generalized anxiety disorder information
Global Health Martz also discusses the anxiety–muscle tension–pain cycle, explaining how emotional stress and physical tension can interact.
When physical symptoms are persistent, severe, or new, they should not automatically be attributed to anxiety. A medical evaluation may be appropriate.
How Are ADHD and Anxiety Diagnosed?
There is no single test that can determine whether someone has ADHD and anxiety together.
A healthcare professional may consider:
- Current symptoms
- Childhood history
- School or work functioning
- Family history
- Sleep
- Mood
- Anxiety patterns
- Medication and substance use
- Physical health
- Daily functioning
- Symptoms across different environments
For adults, establishing a history of ADHD symptoms during childhood is an important part of evaluation. NIMH explains that adult ADHD assessment may involve clinical interviews, rating scales, childhood records, and information from people who know the individual. NIMH ADHD evaluation information
Healthcare professionals also need to consider other explanations.
Sleep problems, depression, anxiety, stress, certain medical conditions, and other factors can produce symptoms that resemble ADHD.
That is why self-diagnosing based only on online symptom checklists can be misleading.
Treatment When ADHD and Anxiety Occur Together
Treatment should be individualized.
A person with ADHD and anxiety may benefit from a plan that addresses both conditions rather than focusing exclusively on one.
1. Psychotherapy
Psychotherapy can help with anxiety, emotional regulation, coping skills, organization, and behavioral patterns.
Cognitive behavioral therapy (CBT), for example, is commonly used for anxiety disorders. It can help people identify unhelpful thinking patterns and develop healthier responses to stressful situations. NIMH information on anxiety treatment
For people with ADHD, therapy may also help with:
- Time management
- Organization
- Breaking large tasks into smaller steps
- Managing procrastination
- Improving routines
- Recognizing emotional triggers
2. ADHD Medication
Medication is one evidence-supported component of ADHD treatment.
NIMH explains that stimulant and nonstimulant medicines can be used in ADHD treatment, depending on the individual situation. NIMH ADHD treatment information
When anxiety is also present, a healthcare professional needs to consider the complete clinical picture, including other medicines, sleep, cardiovascular health, side effects, and potential interactions.
Medication should be taken only as directed by a qualified healthcare professional.
3. Anxiety Treatment and Medication Information
Anxiety treatment can include psychotherapy, medication, or a combination depending on the type and severity of the anxiety disorder.
NIMH explains that treatment for generalized anxiety disorder may include psychotherapy, medication, or both. NIMH generalized anxiety disorder treatment
People researching medication options may encounter different categories of anxiety-related medicines. For example, Global Health Martz provides an Xanax category and an Alprazolam category containing additional medication information.
These pages should be viewed as informational resources, not as a substitute for professional diagnosis or prescribing advice.
Understanding Anxiety Medication Categories
Some medicines used in anxiety treatment can affect alertness, coordination, sleepiness, or concentration.
For example, benzodiazepines such as alprazolam require particular caution because they can cause sedation and can lead to dependence with prolonged or inappropriate use.
Readers researching medication information can review the Xanax category and Alprazolam category on Global Health Martz for additional product information.
However, anyone considering an anxiety medication should first discuss whether it is appropriate with a healthcare professional. Medicines should not be started, stopped, or combined based solely on information found online.
Sleep, Anxiety, ADHD, and Medication Considerations
Sleep difficulties can occur with both ADHD and anxiety.
When sleep problems are significant, the underlying cause should be evaluated instead of automatically treating sleepiness or insomnia with medication.
Global Health Martz also provides a Trazodone category containing information about this medication class.
Trazodone is a prescription medicine with specific indications, precautions, side effects, and interactions. It should not be assumed to be an appropriate treatment simply because someone has difficulty sleeping.
A healthcare professional should determine whether medication is appropriate and how it fits into the person’s overall treatment plan.
Anxiety, Muscle Tension, and Pain
Anxiety can also be associated with muscle tension and physical discomfort.
When someone experiences persistent muscle tightness, spasms, or pain, the underlying cause should be evaluated before choosing medication.
Global Health Martz provides additional information through its Soma category and Pain Relief category.
These resources may help readers understand medication products, but they should not be interpreted as a recommendation that people with anxiety or ADHD should use muscle relaxants or pain medicines.
Some medications can cause drowsiness, interact with other medicines, or create safety concerns when combined with alcohol or other sedating substances.
Gabapentin and Nerve-Pain Information
Physical discomfort can sometimes occur alongside anxiety, although not all pain is anxiety-related.
Gabapentin is a medicine used for certain conditions, including specific types of nerve pain. It is not a general treatment for anxiety or ADHD.
Readers researching medication information can also explore the Gabapentin category on Global Health Martz.
Anyone considering gabapentin should discuss the reason for treatment, potential benefits, side effects, interactions, and appropriate dosing with a healthcare professional.
This distinction is important because treating the wrong underlying cause can delay appropriate care.
Everyday Strategies for Managing ADHD and Anxiety
Professional treatment is important when symptoms significantly interfere with daily life, but practical habits can also support symptom management.
Break Large Tasks Into Smaller Steps
Instead of:
“Finish the entire project.”
Try:
- Open the document.
- Write the heading.
- List three key points.
- Work for 15–20 minutes.
- Take a short break.
- Continue with the next step.
Smaller steps can make an overwhelming task feel more manageable.
Use External Reminders
Calendars, alarms, written lists, phone reminders, and visual schedules can reduce the amount of information you need to hold in your head.
Reduce Unnecessary Distractions
A quieter workspace, fewer notifications, and a consistent work environment may make it easier to maintain attention.
Create Predictable Routines
Regular wake-up times, meals, work periods, exercise, and bedtime routines can reduce daily decision-making.
Manage Worry
If worries repeatedly interrupt work, writing them down and setting aside a specific period to address them later may help some people avoid responding to every anxious thought immediately.
Protect Your Sleep
Consistent sleep habits can support attention, energy, and emotional regulation.
Monitor Caffeine
Caffeine can affect anxiety and sleep in some people. If you notice increased nervousness, racing thoughts, or sleep disruption after caffeine, discuss appropriate changes with a healthcare professional.
When Should You Seek Professional Help?
Consider speaking with a healthcare professional when symptoms:
- Interfere with work or education
- Affect relationships
- Make daily responsibilities difficult
- Cause persistent distress
- Affect sleep significantly
- Lead to frequent avoidance
- Make normal routines difficult
- Continue despite reasonable lifestyle changes
You do not need to wait until symptoms become severe before seeking help.
A professional assessment can clarify whether symptoms are related to ADHD, anxiety, both conditions, another health problem, or several overlapping factors.
Frequently Asked Questions About Anxiety and ADHD
Can anxiety and ADHD occur together?
Yes. Anxiety is a recognized co-occurring condition in people with ADHD. The two conditions can share symptoms such as restlessness and difficulty concentrating, which can make diagnosis more complicated. CDC ADHD and co-occurring conditions
Does ADHD cause anxiety?
ADHD and anxiety are separate conditions. However, difficulties associated with ADHD, such as missed deadlines, disorganization, or repeated mistakes, can contribute to stress and may coexist with an anxiety disorder.
Can anxiety look like ADHD?
Yes. Anxiety can cause concentration problems, restlessness, forgetfulness, and difficulty completing tasks. This is one reason a thorough assessment is important before diagnosing ADHD.
How do I know if I have ADHD or anxiety?
Symptoms alone may not provide the answer. A healthcare professional can examine the timing, severity, history, settings, and underlying patterns of symptoms.
Can ADHD medication help anxiety?
ADHD medication is intended to treat ADHD symptoms and should not automatically be considered an anxiety treatment. The effects and suitability can vary between individuals, so people with both conditions should discuss treatment choices with a healthcare professional.
Can therapy help with both ADHD and anxiety?
Yes. Therapy can help people develop strategies for managing anxiety while addressing practical ADHD-related challenges such as organization, procrastination, time management, and emotional regulation.
Can poor sleep make ADHD and anxiety worse?
Poor sleep can affect concentration, mood, energy, and daily functioning and may make either condition harder to manage. Consistent sleep habits can be a useful part of an overall management plan.
Should someone with anxiety and ADHD take anxiety medication?
Not necessarily. Medication decisions depend on the specific diagnosis, severity of symptoms, medical history, other medicines, and individual circumstances. A healthcare professional should determine whether medication is appropriate.
Final Thoughts
Anxiety and ADHD can occur together, and their symptoms can sometimes overlap so closely that it becomes difficult to determine which condition is responsible for a particular problem.
Difficulty concentrating, restlessness, procrastination, racing thoughts, sleep problems, and feeling overwhelmed can occur with either condition. However, the underlying reasons may be different.
ADHD involves persistent patterns of inattention and/or hyperactivity and impulsivity, while anxiety disorders involve excessive or persistent fear and worry that interferes with daily life. NIMH mental-health information
When both conditions are present, addressing only one may not fully resolve the person’s difficulties. A comprehensive evaluation can help identify overlapping symptoms and create a treatment plan that considers mental health, sleep, physical symptoms, medications, and everyday functioning.
Global Health Martz also provides educational resources covering anxiety and cognitive distortions, anxiety and sleep, and the anxiety–muscle tension–pain cycle, which can help readers understand how different symptoms may interact.
If concentration problems, excessive worry, restlessness, sleep difficulties, or emotional distress are affecting your everyday life, consider speaking with a qualified healthcare professional rather than trying to diagnose yourself.
