Is It ADHD or Anxiety, or Both?

Difficulty concentrating, restlessness, racing thoughts, procrastination, and sleep problems can all be signs of ADHD, anxiety, or both. Because these conditions share many overlapping symptoms, it can be difficult to know what is driving the challenges you’re experiencing.

Understanding the Difference

Although ADHD and anxiety can sometimes look similar, they are fundamentally different conditions.

ADHD is a neurodevelopmental condition that affects attention, impulse control, emotional regulation, and executive functioning skills such as planning, organisation, and time management. Symptoms typically begin in childhood, although some people may not receive a diagnosis until later in life.

Anxiety, on the other hand, is the mind and body’s response to perceived threat, uncertainty, or danger. Anxiety disorders involve excessive and persistent worry that can interfere with daily life, relationships, work, or school.

Why Are ADHD and Anxiety Often Confused?

Both ADHD and anxiety can cause difficulties with concentration, restlessness, irritability, sleep, and feelings of overwhelm.

For example, a child who appears distracted in class may be struggling to sustain attention due to ADHD, or they may be preoccupied with worries about getting something wrong. Likewise, an adult who procrastinates may be avoiding a task because they find it difficult to organise themselves, or because they are anxious about making a mistake.

The behaviour may look similar, but the reason behind it can be very different.

ADHD vs Anxiety: What Are the Clues?

People with ADHD often struggle with attention even when they feel calm. They may be easily distracted, forgetful, disorganised, or find it difficult to prioritise and complete tasks. Impulsivity, fidgeting, and emotional regulation difficulties are also common.

People with anxiety tend to experience difficulty concentrating because their attention is occupied by worry. They may find themselves constantly thinking about what could go wrong, feeling tense or on edge, seeking reassurance, or avoiding situations that make them anxious. Physical symptoms such as muscle tension, headaches, nausea, a racing heart, or difficulty relaxing are also common.

Can You Have Both?

Yes. In fact, ADHD and anxiety commonly occur together.

For some people, the ongoing challenges associated with ADHD, such as forgetting things, missing deadlines, struggling academically, or finding relationships difficult, can contribute to stress and anxiety over time.

At the same time, anxiety can make ADHD symptoms feel worse by making it harder to concentrate, organise tasks, make decisions, and manage everyday responsibilities.

Why Assessment Matters

Because ADHD and anxiety overlap in many ways, it is important not to rely on symptoms alone.

A comprehensive assessment looks at your developmental history, current symptoms, daily functioning, and the underlying reasons those symptoms are occurring. The goal is to understand whether difficulties are related to ADHD, anxiety, both conditions, or something else entirely.
