Can ADHD Cause Anxiety? Understanding the Connection in Adults
ADHD and anxiety frequently occur together in adults, and the relationship between them can be complicated.
An adult with attention-deficit/hyperactivity disorder (ADHD) may experience chronic stress related to missed deadlines, unfinished tasks, forgetfulness, disorganization, work difficulties, or feeling constantly behind. Over time, these challenges may contribute to anxiety.
At the same time, anxiety itself can make it harder to concentrate, remember information, make decisions, and complete tasks—sometimes creating symptoms that resemble or worsen ADHD.
So, can ADHD cause anxiety?
ADHD does not automatically cause an anxiety disorder. However, living with ADHD-related difficulties may contribute to stress and anxiety in some adults, and ADHD and anxiety disorders can also occur together as separate conditions.
At Live Now Psychiatry, Florida adults can receive online ADHD and anxiety evaluations and treatment through secure telehealth appointments.
This guide explains the connection between ADHD and anxiety, why they commonly overlap, how one condition can affect the other, and why identifying what is driving your symptoms matters when developing a treatment plan.

Can ADHD Cause Anxiety in Adults?
ADHD does not necessarily cause an anxiety disorder.
However, ADHD can create circumstances that contribute to chronic stress and anxiety.
Imagine repeatedly:
Forgetting important responsibilities
Missing deadlines
Running late
Losing important items
Falling behind at work
Procrastinating until tasks become urgent
Forgetting appointments
Struggling to organize your home
Having difficulty managing finances
Disappointing people despite genuinely trying
Feeling as though everyone else can manage responsibilities more easily
Over time, these experiences can create considerable stress.
An adult may begin worrying:
“What am I forgetting?”
“Am I going to miss another deadline?”
“Why can't I just get this done?”
“What if I make another mistake at work?”
“How am I already behind again?”
For some adults, anxiety develops partly in response to years of struggling with untreated or inadequately managed ADHD symptoms.
However, anxiety can also exist independently of ADHD.
That distinction is important.

Why ADHD Can Make Adults Feel Anxious
ADHD can affect much more than the ability to concentrate.
It can interfere with executive functions involved in:
Planning
Organization
Working memory
Prioritization
Task initiation
Time management
Sustaining attention
Completing tasks
Controlling impulses
When these difficulties repeatedly interfere with everyday responsibilities, anxiety may follow.
Here are several ways this can happen.
1. Procrastination Can Create Last-Minute Anxiety
Many adults with ADHD struggle to begin tasks even when they understand how important those tasks are.
A deadline that initially seems far away may be repeatedly postponed.
Eventually, the task becomes urgent.
This can create a repeating cycle:
A task needs to be completed
Starting feels difficult
The task is postponed
Anxiety begins increasing
The deadline gets closer
Anxiety becomes intense
Urgency finally makes it easier to focus
The task is completed under pressure
The person feels exhausted
The same pattern happens again
After experiencing this repeatedly, some adults begin feeling anxious as soon as they receive a new assignment because they anticipate the stressful cycle ahead.
2. Forgetfulness Can Create Constant Worry
ADHD can involve forgetfulness in everyday activities.
Someone who frequently forgets responsibilities may begin worrying constantly about what they might have missed.
For example:
Did I pay that bill?
Did I answer that email?
Did I schedule that appointment?
Did I lock the door?
Was there something I needed to do today?
Did I forget something important at work?
The anxiety may partly develop as an attempt to compensate for unreliable memory or organization.
3. Time-Management Problems Can Create Stress
Difficulty estimating and managing time can cause repeated problems.
An adult with ADHD may:
Underestimate how long getting ready will take
Arrive late
Misjudge project deadlines
Become absorbed in one activity
Lose track of time
Have difficulty transitioning between tasks
When this happens frequently, everyday schedules can begin to feel stressful.
A person may start worrying about being late even when there is plenty of time.
4. Work Problems Can Increase Anxiety
ADHD symptoms can affect occupational functioning.
An adult may struggle with:
Long emails
Paperwork
Administrative tasks
Deadlines
Organization
Prioritizing projects
Sitting through meetings
Remembering instructions
Completing repetitive work
If these problems lead to criticism, missed deadlines, poor performance reviews, or fear of losing a job, anxiety can understandably increase.
5. Relationship Difficulties Can Contribute to Anxiety
ADHD can also affect relationships.
A partner may interpret ADHD-related behavior as:
Not listening
Not caring
Being unreliable
Being inconsiderate
Being irresponsible
Meanwhile, the person with ADHD may genuinely care but struggle with attention, working memory, organization, or impulse control.
Repeated conflict can eventually create anxiety about disappointing other people or making another mistake.
6. Feeling Constantly Behind Can Become Overwhelming
Some adults with ADHD describe life as a constant game of catching up.
There may always be:
Another email
Another bill
Another appointment
Another unfinished project
Another household task
Another deadline
Even relatively ordinary responsibilities can begin to feel overwhelming when executive-function difficulties make coordinating them challenging.
This persistent sense of being behind can contribute to chronic stress.
Can Anxiety Make ADHD Symptoms Worse?
Yes, anxiety can make concentration and executive functioning more difficult.
Imagine trying to read an important email while your mind is repeatedly thinking:
“What if something goes wrong?”
It becomes much harder to absorb what you are reading.
Anxiety may contribute to:
Difficulty concentrating
Forgetfulness
Indecisiveness
Trouble completing tasks
Restlessness
Sleep difficulties
Mental fatigue
Feeling overwhelmed
For someone who already has ADHD, significant anxiety may make existing attention difficulties feel even worse.
This can create a cycle:
ADHD symptoms → problems with responsibilities → anxiety → poorer concentration → greater difficulty completing responsibilities → more anxiety
Breaking that cycle may require addressing both conditions when both are present.
ADHD Anxiety vs. an Anxiety Disorder
Feeling anxious because of ADHD-related problems does not necessarily mean someone has an anxiety disorder.
Occasional anxiety is part of normal life.
An anxiety disorder involves excessive or persistent anxiety that meets specific diagnostic criteria and causes clinically significant distress or impairment.
For example, someone with ADHD might primarily worry when:
Deadlines are approaching
Responsibilities have been forgotten
Work is piling up
They are running late
Another person may experience persistent worry across many areas of life even when nothing ADHD-related has gone wrong.
The distinction is not always obvious.
That is why a comprehensive evaluation is important.
For a detailed comparison, read ADHD vs. Anxiety: How to Tell the Difference in Adults.
Can You Have ADHD and Anxiety at the Same Time?
Yes.
An adult can have both ADHD and an anxiety disorder.
Having one condition does not exclude the other.
When both are present, symptoms can interact.
For example, someone may have ADHD-related difficulty starting an assignment and anxiety about whether the assignment will be good enough.
They may procrastinate because of ADHD, anxiety, or a combination of both.
This is why simply asking “Is this ADHD or anxiety?” does not always capture the whole picture.
Sometimes the answer is that both conditions need to be evaluated.
What Does ADHD With Anxiety Feel Like?
Everyone's experience is different, but an adult with both conditions might describe:
Wanting to complete tasks but feeling unable to start
Constantly worrying about forgotten responsibilities
Feeling mentally restless
Overthinking decisions
Becoming overwhelmed by long task lists
Avoiding tasks that feel complicated
Difficulty relaxing
Trouble concentrating because of worry
Trouble concentrating even when not worried
Difficulty sleeping because the mind will not settle
Repeatedly checking calendars or reminders
Feeling exhausted from trying to stay organized
Becoming anxious about making mistakes
Feeling overwhelmed by ordinary responsibilities
These symptoms alone cannot establish either diagnosis.
Many medical and psychiatric conditions can produce similar difficulties.
ADHD vs. Anxiety: Why They Can Be Confused
ADHD and anxiety share several possible symptoms.
Both can involve:
Poor concentration
Restlessness
Sleep difficulties
Forgetfulness
Difficulty completing tasks
Feeling overwhelmed
Irritability
But the underlying reason may differ.
With ADHD
Concentration may be difficult because attention is easily pulled toward competing stimuli, tasks are insufficiently stimulating, or executive-function difficulties interfere with organization.
With Anxiety
Concentration may be difficult because attention is consumed by worry, fear, or repetitive anxious thoughts.
With Both
Both mechanisms may be occurring simultaneously.
This is why diagnosis should involve much more than checking off a list of concentration problems.
Did the ADHD or Anxiety Come First?
The timeline can provide useful information.
ADHD is a neurodevelopmental disorder.
For an ADHD diagnosis, there should be evidence that symptoms were present during childhood, even if ADHD was not diagnosed at that time.
An adult may recall childhood experiences such as:
Daydreaming frequently
Losing homework
Forgetting assignments
Difficulty following directions
Being chronically disorganized
Talking excessively
Interrupting
Difficulty remaining seated
Making careless mistakes
Being described as capable but inconsistent
Anxiety may have developed later.
However, anxiety disorders can also begin during childhood.
A clinician therefore needs to examine the entire history rather than assuming one condition caused the other.

Can Untreated ADHD Lead to Anxiety?
Untreated ADHD may contribute to circumstances that increase anxiety for some adults.
Years of:
Academic struggles
Work difficulties
Relationship conflict
Chronic procrastination
Missed deadlines
Financial disorganization
Repeated criticism
Feeling unreliable
Difficulty meeting expectations
can understandably affect emotional well-being.
However, it is too simplistic to say that untreated ADHD inevitably causes an anxiety disorder.
Many people with ADHD do not develop an anxiety disorder, and anxiety has many potential causes.
The relationship must be evaluated individually.
Can Treating ADHD Improve Anxiety?
Sometimes.
If anxiety is largely related to untreated ADHD impairment, improving ADHD symptoms may reduce some of the stress contributing to anxiety.
For example, if treatment helps someone:
Complete work on time
Stay organized
Remember responsibilities
Manage their schedule
Reduce procrastination
they may naturally feel less anxious about those areas.
However, treating ADHD does not automatically treat an anxiety disorder.
If someone has both ADHD and an anxiety disorder, both may require attention in the treatment plan.
Can ADHD Medication Make Anxiety Worse?
It can in some people.
Stimulant ADHD medications can potentially contribute to:
Nervousness
Feeling jittery
Restlessness
Irritability
Difficulty sleeping
Anxiety
However, response varies considerably.
Some adults report less anxiety when their ADHD symptoms are effectively controlled because they feel more organized and capable of managing responsibilities.
Others experience increased anxiety or other unwanted effects.
Medication response should therefore be monitored individually.
If you are researching ADHD medications, read ADHD Medication Options for Adults.
Can Non-Stimulant ADHD Medication Be Considered When Anxiety Is Present?
Potentially.
Non-stimulant ADHD medications are among the treatment options clinicians may consider for adults with ADHD.
However, having anxiety does not automatically mean a non-stimulant is preferable to a stimulant.
Medication selection may depend on:
ADHD symptom severity
Anxiety symptoms
Medical history
Psychiatric history
Cardiovascular history
Previous medication response
Previous side effects
Sleep
Appetite
Substance-use history
Other medications
Patient preferences
Read Non-Stimulant ADHD Medications for Adults: Options, Benefits, and Side Effects.
Which Should Be Treated First: ADHD or Anxiety?
There is no universal rule that ADHD must always be treated before anxiety or vice versa.
Treatment sequencing depends on the individual.
A clinician may consider:
Which condition is causing the greatest impairment
Severity of anxiety
Severity of ADHD
Medical history
Psychiatric history
Sleep
Substance use
Previous treatment response
Medication risks and interactions
Patient preferences
Sometimes treatment may focus primarily on one condition initially.
In other cases, both conditions may need to be addressed as part of a comprehensive treatment plan.
How Are ADHD and Anxiety Treated When They Occur Together?
Treatment should be individualized.
Depending on the patient, treatment may involve:
ADHD medication when appropriate
Anxiety medication when appropriate
Psychotherapy
Cognitive behavioral approaches
Organizational strategies
Executive-function strategies
Stress-management techniques
Sleep optimization
Lifestyle interventions
Ongoing psychiatric follow-up
Medication is not the only component of treatment.
The goal is to improve the symptoms and functional problems that are interfering with everyday life.

Could Something Else Be Causing Poor Concentration and Anxiety?
Yes.
Difficulty concentrating and anxiety-like symptoms are not specific to ADHD or anxiety disorders.
Similar symptoms can occur with:
Depression
Insomnia
Chronic sleep deprivation
Trauma-related conditions
Substance use
Medication effects
Thyroid disorders
Other medical conditions
This is another reason an appropriate clinical evaluation matters.
A symptom checklist alone cannot determine the diagnosis.
How Is ADHD Evaluated When Anxiety Is Also Present?
An ADHD evaluation should look beyond current concentration difficulties.
A clinician may review:
Current ADHD symptoms
Childhood symptoms
Anxiety symptoms
When each set of symptoms began
Functional impairment
Work or school functioning
Home functioning
Relationship functioning
Medical history
Psychiatric history
Sleep
Substance use
Current medications
Family history
Other possible explanations for symptoms
The timeline is particularly important.
ADHD requires evidence of symptoms beginning during childhood.

ADHD and Anxiety in Women
ADHD can sometimes be recognized later in women, particularly when inattentive symptoms were overlooked earlier in life.
Some women may first seek help for:
Anxiety
Feeling overwhelmed
Chronic disorganization
Procrastination
Forgetfulness
Difficulty keeping up with responsibilities
An evaluation may reveal ADHD, anxiety, both conditions, or another explanation entirely.
When Should You Consider an Evaluation?
Consider speaking with a qualified healthcare professional if persistent problems with anxiety, attention, organization, or executive functioning are interfering with:
Work
School
Relationships
Household responsibilities
Finances
Sleep
Daily functioning
Overall quality of life
You do not need to determine whether you have ADHD or anxiety before seeking help.
Determining what is causing the symptoms is part of the evaluation.

Frequently Asked Questions About ADHD and Anxiety
Can ADHD Cause Anxiety?
ADHD does not automatically cause an anxiety disorder.
However, ADHD-related difficulties such as chronic disorganization, missed deadlines, forgetfulness, and problems completing responsibilities may contribute to stress and anxiety in some adults.
Is Anxiety Common in Adults With ADHD?
ADHD and anxiety disorders can occur together.
An adult with ADHD may have a separate anxiety disorder, anxiety related partly to ADHD-related impairment, or both.
How Do I Know if My Anxiety Is From ADHD?
It can be difficult to determine without an evaluation.
Anxiety that occurs mainly around ADHD-related problems may suggest a connection, but persistent worry across many areas of life may indicate an anxiety disorder.
The two can also coexist.
Can Anxiety Look Like ADHD?
Yes.
Anxiety can cause difficulty concentrating, restlessness, sleep problems, forgetfulness, and difficulty completing tasks.
This can sometimes resemble ADHD.
Can ADHD Look Like Anxiety?
Yes.
ADHD-related restlessness, overwhelm, procrastination, missed responsibilities, and executive-function difficulties can sometimes be interpreted as anxiety.
Can You Have ADHD and Anxiety Together?
Yes.
ADHD and anxiety disorders can coexist.
Having one does not rule out the other.
Can ADHD Medication Help Anxiety?
Sometimes anxiety related to ADHD-related impairment may improve when ADHD is effectively treated.
However, ADHD medication is not automatically a treatment for an anxiety disorder.
Can Stimulants Make Anxiety Worse?
They can in some individuals.
Stimulant medications may cause nervousness, jitteriness, restlessness, insomnia, or anxiety in some patients.
Other patients may experience less anxiety as ADHD-related functioning improves.
Should ADHD or Anxiety Be Treated First?
There is no universal answer.
Treatment depends on symptom severity, functional impairment, medical and psychiatric history, safety considerations, and the individual's clinical needs.
Does ADHD Cause Overthinking?
ADHD can involve mental restlessness and difficulty regulating attention, while anxiety commonly involves repetitive worry.
“Overthinking” is not itself a diagnostic criterion for ADHD and can have many causes.
Does ADHD Cause Panic Attacks?
Panic attacks are not a core symptom of ADHD.
Someone with ADHD can also have panic disorder or experience panic attacks for other reasons.
New or severe panic symptoms should be appropriately evaluated.
Can ADHD Cause Social Anxiety?
ADHD does not automatically cause social anxiety disorder.
However, repeated social difficulties, impulsive behavior, forgetfulness, or negative experiences may contribute to anxiety in social situations for some people.
Social anxiety can also occur independently.
Can Adults Receive Treatment for ADHD and Anxiety Through Telepsychiatry in Florida?
Yes. A Florida-licensed clinician may evaluate and treat adults through telehealth when clinically appropriate.
An evaluation does not guarantee a particular diagnosis or prescription for any specific medication.
