ADHD or Anxiety? How to Tell the Difference

Written By molly pritchard

Many adults come to their first psychiatric appointment wondering the same thing:

"Do I have anxiety, ADHD, or both?"

The confusion is understandable. ADHD and anxiety can look remarkably similar on the surface. Both can cause difficulty concentrating, racing thoughts, procrastination, forgetfulness, overwhelm, and trouble sleeping.

In fact, many people spend years treating anxiety without realizing that ADHD may also be contributing to their symptoms.

Understanding the differences between ADHD and anxiety can help you better understand your experiences and guide the most effective treatment approach.

Why ADHD and Anxiety Look So Similar

ADHD and anxiety affect different areas of the brain, but they often create similar day-to-day challenges.

Both conditions can lead to:

  • Difficulty concentrating

  • Feeling overwhelmed

  • Restlessness

  • Racing thoughts

  • Difficulty completing tasks

  • Trouble sleeping

  • Irritability

  • Mental exhaustion

Because of this overlap, it can be difficult to know what's driving your symptoms.

The key is understanding why those symptoms are happening.

Signs Your Symptoms May Be Related to Anxiety

Anxiety is typically driven by excessive worry, fear, or anticipation of future problems.

People with anxiety often find themselves thinking:

  • "What if something goes wrong?"

  • "What if I make a mistake?"

  • "What if people judge me?"

  • "What if I fail?"

Common anxiety symptoms include:

Excessive Worry

You may spend significant time thinking about potential problems, even when there's no immediate threat.

Physical Symptoms

Anxiety often affects the body, causing symptoms such as:

  • Muscle tension

  • Rapid heart rate

  • Upset stomach

  • Sweating

  • Restlessness

  • Feeling "on edge"

Difficulty Relaxing

Many people with anxiety describe feeling unable to fully relax because their minds are constantly anticipating the next problem.

Fear-Based Avoidance

You may avoid situations because they feel overwhelming or because you're worried about what could happen.

Signs Your Symptoms May Be Related to ADHD

ADHD is a neurodevelopmental condition that affects executive functioning.

Executive functions help us:

  • Plan

  • Organize

  • Prioritize

  • Manage time

  • Start tasks

  • Complete tasks

  • Regulate attention

People with ADHD often struggle not because they're worried, but because their brains process information differently.

Common signs include:

Chronic Procrastination

You know something needs to be done.

You want to do it.

Yet somehow getting started feels incredibly difficult.

Time Blindness

You underestimate how long tasks will take, lose track of time, or frequently run late despite good intentions.

Forgetfulness

You may:

  • Miss appointments

  • Misplace important items

  • Forget tasks

  • Lose track of conversations

Difficulty Prioritizing

Everything feels equally important, making it hard to determine where to begin.

Lifelong Patterns

Unlike anxiety, ADHD symptoms are usually present from childhood, even if they weren't recognized at the time.

When ADHD Creates Anxiety

This is where things get tricky.

Many adults with ADHD develop anxiety because of the challenges ADHD creates.

Imagine years of:

  • Missing deadlines

  • Forgetting appointments

  • Losing important items

  • Feeling behind

  • Being criticized for being "disorganized"

Over time, it makes sense that anxiety would develop.

Many people with ADHD become hypervigilant because they're constantly trying to compensate for executive functioning difficulties.

In these cases, anxiety may be a consequence of ADHD rather than the primary issue.

Can You Have Both?

Absolutely.

Research suggests that anxiety disorders commonly occur alongside ADHD.

Many adults experience both conditions simultaneously.

For example:

ADHD may cause:

  • Disorganization

  • Time management difficulties

  • Forgetfulness

Anxiety may add:

  • Excessive worry

  • Fear of making mistakes

  • Constant overthinking

When both are present, symptoms can feel especially overwhelming.

Questions to Ask Yourself

Consider the following:

Did these difficulties exist during childhood?

ADHD symptoms often begin early, even if they weren't diagnosed.

Do you worry excessively?

Persistent worry is more characteristic of anxiety.

Are you struggling because you're worried—or because you're overwhelmed by tasks?

This distinction can be helpful.

Do you frequently lose things, forget appointments, or underestimate time?

These symptoms often point toward ADHD.

Have you always felt disorganized despite trying hard?

Many adults diagnosed with ADHD describe exactly this experience.

Why an Accurate Diagnosis Matters

ADHD and anxiety can both be treated effectively, but treatment approaches may differ.

Understanding the underlying cause of your symptoms can help guide:

  • Medication decisions

  • Therapy recommendations

  • Lifestyle strategies

  • Workplace accommodations

  • Academic support

Most importantly, it can provide clarity.

Many people spend years blaming themselves for struggles that are actually related to an underlying condition.

Final Thoughts

If you've been wondering whether ADHD, anxiety, or both may be contributing to your symptoms, you're not alone.

These conditions frequently overlap, and the differences aren't always obvious.

A comprehensive evaluation can help clarify what's happening and identify the most effective path forward.

You don't need to keep guessing—or continue struggling without answers.
