Separation anxiety disorder

Overview & Epidemiology - Clingy Kid Conundrum

• Developmentally inappropriate and excessive fear/anxiety concerning separation from those to whom the individual is attached.
• Most common anxiety disorder in children < 12 years old; prevalence approx. 4%.
• Symptoms must last at least 4 weeks in children/adolescents and typically 6 months or more in adults.
• Often precipitated by a major life stressor (e.g., death of a pet, illness, moving).

⭐ School refusal is a common and impairing feature.

Clinical Presentation & DSM-5 - Tell-Tale Tantrums

• Core Feature: Developmentally inappropriate, excessive anxiety over separation from attachment figures.
• Key Symptoms (≥3 required):
  • Distress when anticipating or experiencing separation.
  • Worry about losing attachment figures or harm coming to them.
  • Worry about an event causing separation (e.g., getting lost, kidnapped).
  • Reluctance/refusal to go to school, work, or elsewhere.
  • Fear of being alone or without attachment figures at home.
  • Reluctance/refusal to sleep away from home or without them near.
  • Nightmares involving themes of separation.
  • Somatic complaints (headaches, nausea) when separation is anticipated.
• Duration: Symptoms last ≥ 4 weeks in children/adolescents; ≥ 6 months in adults.

⭐ School refusal is a classic presentation. Look for somatic complaints that appear on weekday mornings but are absent on weekends/holidays.

Differential Diagnosis - Not Just Nerves

• Normal Developmental Anxiety: Expected in toddlers (peaks 9-18 months); less intense.
• Other Anxiety Disorders:
  • Generalized Anxiety Disorder (GAD): Worry is pervasive, not focused on separation.
  • Social Anxiety Disorder: Fear centers on social scrutiny, not leaving caregivers.
  • Panic Disorder: Attacks are often spontaneous, not just separation-triggered.
• Disruptive Behavior Disorders (ODD/Conduct): School refusal stems from defiance, not fear.

⭐ In cases of school refusal, differentiate if the child fears leaving the caregiver (Separation Anxiety) versus fearing the school environment itself (e.g., bullying, Social Anxiety).

Management & Treatment - Calming the Chaos

• Psychotherapy is first-line.

  • Cognitive-Behavioral Therapy (CBT) is the cornerstone.
    • Techniques: Psychoeducation, relaxation skills, cognitive restructuring.
    • Graded exposure: Systematically confronting feared situations (e.g., brief separations).
  • Family therapy addresses family dynamics that maintain anxiety.

• Pharmacotherapy for moderate-to-severe cases.

  • SSRIs (e.g., fluoxetine, sertraline) are the first-line medication.
  • Benzodiazepines may be used for short-term, severe distress but are not first-line.

⭐ School refusal is a common presentation of separation anxiety disorder; a multidisciplinary approach involving school staff is crucial for successful reintegration.
