ADHD and Anxiety: Understanding the Common Comorbidity

You can’t focus because you’re anxious, and you’re anxious because you can’t focus. Deadlines loom and you’re paralyzed, unable to start but unable to stop worrying. Your racing thoughts might be ADHD or might be anxiety—or maybe both, tangled so tightly together you can’t tell where one ends and the other begins.

ADHD and anxiety are frequent companions. About half of adults with ADHD also have an anxiety disorder. When they co-occur, each condition can worsen the other, creating challenges that neither condition alone would produce. Understanding this relationship is key to finding relief.

How Common Is the Overlap?

Statistics

• About 50% of adults with ADHD have an anxiety disorder
• About 25% of people with anxiety disorders have ADHD
• The overlap is higher than would be expected by chance
• Generalized anxiety disorder (GAD) is most commonly co-occurring

Why So Common?

Several factors explain the high comorbidity:

Shared Neurobiology:
Both conditions involve dysregulation in similar brain regions and neurotransmitter systems.

ADHD Leads to Anxiety:
Years of struggling, failing, and disappointing others creates legitimate reasons to worry.

Overlapping Symptoms:
Some symptoms appear in both conditions, increasing chances of dual diagnosis.

Life Consequences:
The real-world consequences of ADHD (job loss, relationship problems, academic failure) cause anxiety.

How ADHD Causes Anxiety

Chronic Underperformance

When you know you’re capable but consistently underperform:

• You develop anxiety about your abilities
• Fear of failure increases
• Self-doubt becomes pervasive
• Starting tasks becomes frightening

Accumulating Consequences

ADHD often leads to:

• Financial problems (impulsive spending, disorganization)
• Relationship difficulties
• Job instability
• Academic struggles

These real consequences create legitimate worry.

Anticipatory Anxiety

Knowing your ADHD will cause problems creates anxiety about:

• Upcoming deadlines
• Important meetings
• Anything requiring sustained focus
• Situations where you might “mess up”

Social Anxiety from Social Missteps

ADHD symptoms like interrupting, not listening, and social impulsivity lead to:

• Negative feedback from others
• Social rejection
• Fear of social situations
• Avoiding interactions

Living in Chaos

The disorganization of ADHD creates:

• Constant low-level stress
• Fear of what you’re forgetting
• Anxiety about looming disasters
• Difficulty relaxing

How Anxiety Worsens ADHD

Cognitive Overload

Anxiety takes up mental bandwidth:

• Less capacity for focus and attention
• Working memory further impaired
• Executive function compromised
• Racing anxious thoughts compete with tasks

Avoidance

Anxiety drives avoidance of anxiety-provoking situations:

• Putting off anxiety-causing tasks (which also require ADHD-deficient skills)
• Avoiding situations where symptoms might show
• Procrastination increases
• Deadlines become more overwhelming

Physical Symptoms

Anxiety’s physical symptoms compound ADHD:

• Restlessness (already present in hyperactive ADHD)
• Difficulty concentrating (already ADHD symptom)
• Sleep problems (worsen ADHD functioning)
• Fatigue from being constantly on alert

Perfectionism Trap

Anxiety often creates perfectionism:

• Can’t start until you can do it perfectly
• Can’t finish because it’s not good enough
• Paralysis from fear of imperfection
• Compounds ADHD-related task initiation difficulties

Distinguishing ADHD from Anxiety

Overlapping Symptoms

Some symptoms appear in both:

Difficulty Concentrating:
– ADHD: Attention wanders to more interesting things
– Anxiety: Attention stuck on worries

Restlessness:
– ADHD: Need to move, excess energy
– Anxiety: Nervous energy, can’t relax

Sleep Problems:
– ADHD: Mind won’t turn off, seeking stimulation
– Anxiety: Worry prevents sleep

Irritability:
– ADHD: Frustration intolerance
– Anxiety: On edge from constant worry

Key Differences

Focus Issues:

ADHD:
– Attention drawn to more stimulating things
– Can hyperfocus on interesting things
– Distraction is relatively easy, almost pleasant
– Boredom is unbearable

Anxiety:
– Attention stuck on worries
– Can’t focus because of intrusive worries
– Distraction is hard because worry feels important
– Worry feels necessary

Restlessness:

ADHD:
– Physical need to move
– Present even when not worried
– Movement itself is satisfying
– Often improved by physical activity

Anxiety:
– Restlessness from nervous energy
– Connected to worry
– Movement doesn’t necessarily help
– May still feel agitated after exercise

What Triggers Symptoms:

ADHD:
– Symptoms worst with boring, routine tasks
– Better with novel, interesting activities
– Present across situations

Anxiety:
– Symptoms worst when facing feared situations
– Better when worries are addressed
– Tied to specific stressors

When It’s Both

Often, it truly is both conditions:

• ADHD creates situations that cause anxiety
• Anxiety worsens ADHD functioning
• Both have independent symptoms
• Treatment needs to address both

Treatment Considerations

Assessment First

Proper diagnosis is crucial:

• Comprehensive evaluation of both conditions
• Understanding which came first (if possible)
• Identifying how they interact for you specifically
• Ruling out other conditions

Treating One May Help Both

Sometimes treating one condition improves the other:

Treating ADHD:
– Better functioning reduces anxiety about performance
– Less chaos means less to worry about
– Success builds confidence
– May be enough if anxiety is secondary to ADHD

Treating Anxiety:
– Reduced worry frees mental bandwidth
– Less avoidance means tackling tasks
– Better sleep improves ADHD functioning
– May be enough if ADHD symptoms are mild

Medication Considerations

ADHD Medications and Anxiety:

Stimulants may:
– Increase anxiety in some people
– Actually decrease anxiety in others (by improving functioning)
– Need careful monitoring
– Require lower doses or different timing

Non-stimulant options:
– Atomoxetine (Strattera) may help both
– Guanfacine may reduce anxiety and help ADHD
– May be better starting points when anxiety is prominent

Anti-Anxiety Medications:
– Can help reduce anxiety component
– May not address underlying ADHD
– SSRIs are often first-line for anxiety
– Benzodiazepines typically avoided long-term

Combined Approaches:
Many people need medication for both conditions.

Therapy Approaches

CBT for Anxiety:
– Addresses anxious thought patterns
– Teaches coping skills
– Builds tolerance for uncertainty
– Effective for both conditions

CBT for ADHD:
– Builds organizational skills
– Addresses ADHD-specific thought patterns
– Creates structures for functioning
– May reduce anxiety through better functioning

Mindfulness-Based Approaches:
– Help with both attention and anxiety
– Build present-moment awareness
– Reduce reactivity to thoughts
– Evidence for both conditions

Combined Treatment:
Often therapy addressing both conditions is most effective.

Self-Help Strategies

For the Anxiety Component

Worry Time:
Designate specific time for worrying rather than all day.

Reality Testing:
Question anxious thoughts for evidence.

Relaxation Practices:
Deep breathing, progressive muscle relaxation.

Limit Anxiety Triggers:
Reduce caffeine, news consumption, etc.

For the ADHD Component

External Structure:
Calendars, reminders, organizational systems.

Break Tasks Down:
Smaller steps are less overwhelming.

Body Doubling:
Work alongside others for accountability.

Movement:
Regular exercise helps both conditions.

For Both Together

Good Sleep Hygiene:
Both conditions worsen with poor sleep.

Consistent Routines:
Reduces chaos (anxiety trigger) and need for executive function (ADHD challenge).

Self-Compassion:
Both conditions involve shame and self-criticism.

Realistic Expectations:
Perfection isn’t possible; “good enough” is the goal.

Managing the Interaction

Recognize the Cycle:
– Notice when anxiety worsens ADHD
– Notice when ADHD failures increase anxiety
– Interrupt the cycle where you can

Prioritize:
– You can’t fix everything at once
– Address the most pressing issue
– Build momentum from small successes

Get Support:
– Tell trusted others about both conditions
– Ask for help when needed
– Build a support system

Treatment approaches exist that address both conditions. Medication can help, therapy can help, and lifestyle strategies can help. Many people with both ADHD and anxiety find significant relief through comprehensive treatment.
