Anxiety is the nervous system's adaptive response to perceived threat. With an estimated prevalence of 15-20% in school-age children, anxiety disorders are the most common mental health problems in childhood and adolescence, and frequently co-occur with ADHD, ASD and giftedness.

Types of childhood anxiety: not all anxiety is the same
| Disorder | Characteristics | Common age of onset |
|---|---|---|
| Separation anxiety disorder | Intense fear of being separated from attachment figures; school refusal, morning somatic complaints | 6-8 years |
| Generalised anxiety disorder | Excessive worry about multiple topics; perfectionism; "very serious" child | 8-12 years |
| Specific phobia | Intense fear of a specific stimulus | Variable |
| Social anxiety disorder | Intense fear of others' judgement; social avoidance | 8-15 years |
| Panic disorder | Sudden anxiety attacks with physical symptoms | Adolescence |
Warning signs: how anxiety manifests in children
Children often cannot verbally express their anxiety. Instead they present it through: somatic complaints (recurrent stomach aches in the morning, headaches, nausea), avoidance behaviours (school refusal, social avoidance), irritability and explosiveness (anxiety in children frequently manifests as irritability, not fear), hypervigilance (excessive need for control, repetitive questioning) and sleep problems.
The neurobiology of child anxiety
Anxiety activates the amygdala, which coordinates the body's alarm response. When the amygdala activates intensely, the prefrontal cortex —responsible for emotional regulation— has reduced capacity to act. That's why telling a child "don't worry" doesn't work: worry is not a rational decision, it's a neurobiological response. CBT helps the child gradually reclassify stimuli and train the brain to respond less alarmingly.
Family support strategies
Core principle: The goal is not to eliminate a child's anxiety but to help them tolerate it and function despite it. Protecting them from all anxiety-provoking situations prevents them from learning that they can cope.
- Validate without amplifying: Acknowledge the emotion without confirming the danger.
- Gradual exposure: Design progressive exposures to feared situations.
- Avoid excessive reassurance: Constant reassurance maintains anxiety long-term.
- Regulation techniques: Diaphragmatic breathing, sensory grounding (5-4-3-2-1), progressive muscle relaxation.
Frequently asked questions
The key distinction is not the presence of anxiety (which is normal and adaptive) but its intensity, duration and functional impact. When anxiety lasts more than 4 weeks, is disproportionate to the objective situation, and interferes with at least one important area of the child's functioning (school, friendships, family), professional consultation is recommended.
Often, but not always. It may stem from separation anxiety, social anxiety, school phobia, but also from bullying, undetected learning difficulties, or family factors. Clinical assessment is necessary to determine the cause and guide intervention.
