Anxiety and executive function are closely connected. If worry makes it harder to hold instructions in mind, start a task, or make a simple decision, it reflects how anxiety uses up the mental resources that planning and focus depend on. The relationship is real, though it is not simple, and understanding it matters for choosing the right kind of support.
Understanding Anxiety and Executive Function
Executive function covers the mental skills behind planning, starting tasks, holding information in mind and shifting attention between things. Anxiety, which involves persistent worry, heightened alertness and an anticipation of threat, draws on many of the same cognitive resources.
A meta-analysis of 177 samples involving over 22,000 participants found an average association between anxiety and reduced working memory performance.1
What is working memory?
Working memory is the ability to hold and use information in mind while doing something else; it underpins following instructions, planning steps and staying on task.
A later review found the relationship complex, with possible bidirectional effects and meaningful differences across developmental stages.2 For some people, anxiety worsens when executive demands increase; for others, difficulty managing tasks fuels more anxiety. Often, both happen at once.
Anxiety and Executive Function in Adults
Executive functioning and anxiety can interact in specific ways in adult life. Re-reading the same paragraph because worry pulled attention away. Delaying a decision because every option feels risky. Knowing what to do and still not being able to start, because the energy that initiation needs has been spent managing a background state of dread.
Anxiety and concentration problems tend to show up most clearly in tasks that require sustained, self-directed effort: writing, planning, working without external prompts or deadlines. This pattern is often mistaken for laziness or avoidance by other people and by the person experiencing it. It is neither.
Anxiety and Executive Function in Children
Anxiety in children can look like repeated questions before starting a task, refusal to begin, or difficulty holding multi-step instructions while simultaneously managing the feeling that something bad might happen. NHS guidance on childhood anxiety identifies concentration difficulties as a recognised symptom.4
Children often cannot articulate what is making a task hard. The anxiety is usually the more urgent issue; the executive difficulty is happening on top of it. School, with its social pressures and performance expectations, often carries more anxiety than home, producing a confusing pattern where ability seems to shift between contexts.
Anxiety, ADHD and Other Possible Explanations
A common question: is this anxiety, ADHD, or both? The two can produce similar-looking difficulties, including trouble focusing, difficulty starting tasks and working memory problems. They are not the same, and both can be present simultaneously.
ADHD requires a full specialist assessment, not diagnosis from executive-function patterns or anxiety symptoms alone.5 Someone who finds concentration difficult and is also anxious may have anxiety, ADHD, both, or neither as a diagnosable condition. Identifying which is driving what requires proper assessment, not a checklist.
For a broader overview of executive difficulties across different conditions, understand what executive dysfunction is.
Reduce the Pressure Around the Task
Reducing the anxiety load around a task is often more useful than adding complexity to the task itself.
| Barrier | Support approach |
| Worry interrupting concentration | Short, defined working periods; write the worry down and return to it later. |
| Difficulty starting | Remove a step; agree on the smallest possible first action. |
| Decision paralysis | Limit the options; write pros and cons before the decision point, not during. |
| Child resisting tasks | Allow extra processing time; reduce the number of steps visible at once. |
None of these is a treatment for anxiety. They reduce the executive demand, while other support addresses the anxiety itself.
How Therapy and Coaching Play Different Roles
CBT (cognitive behavioural therapy, a structured approach that examines the relationship between thoughts, feelings and behaviour) is a recommended treatment for anxiety in adults.3 NICE guidance supports it for generalised anxiety and related presentations. Anxiety-focused CBT targets the anxiety itself, which may in turn reduce some cognitive difficulties.
Practical coaching can help someone build systems for organisation and task management, and it can run alongside therapy.
The two are different: coaching is practical and present-focused, while therapy addresses the anxiety driving the difficulty. Executive-function difficulties linked to anxiety often respond best to both.
Therachange offers CBT for anxiety delivered online by accredited UK therapists. If practical coaching is also relevant, executive function coaching is available alongside clinical work.

Can anxiety cause executive dysfunction?
Anxiety is associated with reduced working memory and attention, which are core executive functions.1 It can contribute to difficulties with focus, planning and task initiation, though whether anxiety is the main cause or one factor among several depends on the individual.
Can anxiety make you forget instructions?
Yes, in some circumstances. Anxiety draws on working memory, reducing the capacity available for holding and using information. This can look like forgetting, though the underlying process is interference rather than a memory storage problem.
How can I tell anxiety from ADHD?
Both can produce focus difficulties and trouble starting tasks. Anxiety tends to link to specific worrying thoughts; ADHD difficulties are typically more pervasive and present from childhood. Both can coexist and both warrant proper clinical assessment.
Can CBT help concentration problems linked to anxiety?
CBT treats anxiety, not executive dysfunction directly. If anxiety is contributing to concentration difficulties, addressing it through CBT may reduce some of those effects. NICE recommends CBT for generalised anxiety disorder in adults.3
When should I get help for my child’s anxiety?
If your child’s anxiety is persistent, is causing distress and is affecting schoolwork, relationships or daily routines, that is a reasonable point to seek support. NHS guidance recommends speaking to a GP or the school if anxiety is significantly interfering with a child’s life.4
