Anxiety Disorder

Written by Liz Crawford, CAMHS Specialist Nurse (RMN, MSc Child and Adolescent Mental Health), 10 years CAMHS Tier 3

Definition

Anxiety disorder is the umbrella for persistent, disproportionate worry or fear that significantly interferes with everyday life, covering generalised anxiety, separation anxiety, social anxiety, specific phobias, panic disorder, and selective mutism. NICE CG159 (social anxiety) and CG113 (generalised anxiety) cover treatment in children and young people.

In context for parents

Key checkpoints

  • Anxiety disorders include generalised anxiety, separation anxiety, social anxiety, phobias, panic, and selective mutism.
  • NICE CG159 covers social anxiety; CG113 covers generalised anxiety in children and young people.
  • NHS Digital MHFE survey (2023) put probable mental disorder in 7–16-year-olds at 20%, mostly anxiety-led.
  • CBT, graded exposure, predictability, key adult relationships are the evidenced approaches.
  • Equality Act 2010 reasonable adjustments cover anxiety where it amounts to a long-term impairment (12 months+).

Anxiety in SEND is rarely a stand-alone picture. It is the frequent driver of school avoidance, meltdowns, shutdowns, and behavioural incidents, and is often the unmet need behind a child labelled "challenging". The MHFE (Mental Health of Children and Young People in England, NHS Digital 2023) survey put the rate of probable mental disorder in 7–16-year-olds at 20%, the majority anxiety-led. CAMHS thresholds in 2026 remain high (moderate-to-severe is the typical access bar) which leaves many anxiety presentations sitting with school and family alone.

In a Year 4 classroom, anxiety looks like the child who needs the toilet during every maths lesson, who cannot start a written task because the first sentence feels too high stakes, who masks all morning and explodes at home at 4pm, or whose attendance has dropped from 96% to 78% in a term with no obvious cause. The teacher sees behaviour; the parent sees a child taking three hours to leave the house each morning.

What helps: CBT (Cool Kids, Anna Freud's programmes), graded exposure rather than full removal of the trigger, predictability and visual schedules, a key adult relationship at school, and family psychoeducation. Reasonable adjustments under the Equality Act 2010 cover anxiety where it amounts to a long-term impairment: flexible start times, exit cards, quiet space access, modified assemblies.

EBSA is treated separately. Where anxiety is severe enough to require provision beyond what school can routinely arrange, for example named therapy hours, modified timetable as a transition tool, or specialist placement, it can meet the EHC needs assessment threshold.

Where parents ask about this

Parents usually find this page after CAMHS has rejected a referral for being "below threshold", after weeks of escalating school refusal, or before an annual review where the school has framed anxiety as parenting. Searches include "school refusal anxiety help UK", "private CBT for children", and "EBSA EHCP". A Beaakon clinical psychologist or CAMHS-experienced clinician can carry out a formulation, begin evidence-based therapy without an NHS wait, and write a school-side adjustment plan or Section F-grade provision for an EHC needs assessment.
