ADHD or Anxiety: How Can You Tell the Difference?

By Virginia Lindahl, PhD

Many people wonder whether difficulties with focus, organization, restlessness, procrastination, or overwhelm are caused by ADHD, anxiety, or both.

The confusion is understandable because ADHD and anxiety can look surprisingly similar on the surface. Both can affect:

  • concentration

  • memory

  • task completion

  • sleep

  • emotional regulation

  • productivity

  • school or work performance

At the same time, the underlying reasons for these difficulties are often very different.

Understanding those differences can help guide more effective treatment and support.

How Anxiety Can Affect Attention

When someone is anxious, the brain often becomes highly focused on perceived threats, worries, uncertainty, or internal distress.

A person experiencing anxiety may:

  • overthink decisions

  • mentally rehearse conversations

  • become preoccupied with fears or “what if” scenarios

  • struggle to disengage from worry

  • avoid tasks that feel overwhelming

  • have difficulty concentrating because their attention is pulled toward anxious thoughts

Many anxious people describe:

I can focus, but my brain won’t stop worrying.

In these situations, attention problems may improve when anxiety decreases.

How ADHD Affects Attention Differently

ADHD is generally not caused by excessive worry. Instead, it involves differences in executive functioning and self-regulation that affect the ability to consistently direct and sustain attention.

People with ADHD may struggle with:

  • task initiation

  • organization

  • time management

  • working memory

  • sustaining attention on less stimulating tasks

  • impulsivity

  • regulating focus effectively

Many people with ADHD can focus very well in situations that are:

  • highly stimulating

  • urgent

  • emotionally engaging

  • novel

  • fast-paced

but struggle substantially with tasks that are repetitive, delayed, administrative, or less immediately rewarding.

People with ADHD often describe experiences such as:

I know what I need to do, but I can’t get myself to start.

ADHD and Anxiety Often Overlap

ADHD and anxiety frequently occur together.

For example, someone with ADHD may develop anxiety after years of:

  • missed deadlines

  • disorganization

  • inconsistent performance

  • academic struggles

  • negative feedback

  • chronic overwhelm

At the same time, chronic anxiety can also create difficulties with concentration, memory, sleep, and executive functioning.

Over time, the two can become difficult to separate without a more comprehensive evaluation.

Why It Can Be Difficult to Tell the Difference

Looking only at surface behaviors can sometimes be misleading.

For example:

  • procrastination may reflect executive functioning difficulties, anxiety, perfectionism, avoidance, or some combination of these factors

  • distractibility may stem from external stimulation, intrusive worry, sleep deprivation, or attentional regulation difficulties

  • restlessness may reflect hyperactivity, nervous system arousal, stress, or emotional distress

This is one reason comprehensive psychological evaluation can sometimes be helpful.

How Psychological Testing Can Help

Comprehensive psychological or psychoeducational evaluation may help clarify:

  • attentional functioning

  • executive functioning

  • anxiety symptoms

  • learning difficulties

  • emotional factors

  • cognitive patterns

  • behavioral patterns

Testing does not simply look at whether someone appears inattentive. Instead, the goal is often to understand:

  • why the difficulties are occurring

  • which factors may be contributing

  • how different areas of functioning interact with one another

This can help guide treatment recommendations, accommodations, and support strategies more effectively.
