Oxytocin Levels in Children with Separation Anxiety and Their Mothers before and after Treatment

Area of Science:

• Neuroendocrinology
• Child Psychiatry
• Psychoneuroimmunology

Background:

• Separation anxiety disorder (SAD) is a common childhood anxiety disorder.
• Oxytocin, a neuropeptide, plays a role in social bonding and stress regulation.
• Altered oxytocin levels have been implicated in various psychiatric conditions, including anxiety disorders.

Purpose of the Study:

• To compare plasma oxytocin levels in children with SAD and their mothers versus healthy controls.
• To investigate the relationship between oxytocin levels and anxiety changes following treatment in children with SAD.

Main Methods:

• Participants included 30 children (6-12 years) with SAD, 30 healthy children, and their mothers.
• Assessments involved semi-structured interviews, the Clinical Global Impression Scale, and psychological questionnaires.
• Plasma oxytocin levels were measured before and after a three-month treatment period for the SAD group.

Main Results:

• Mothers of children with SAD had significantly lower plasma oxytocin levels than controls; these levels increased post-treatment.
• No significant difference in plasma oxytocin was found between children with SAD and controls initially.
• Children with SAD showed a significant decrease in plasma oxytocin levels after treatment, positively correlating with reduced anxiety scores.

Conclusions:

• Changes in plasma oxytocin levels in both children and mothers suggest oxytocin's involvement in the etiology of SAD.
• Oxytocin may serve as a potential biomarker or therapeutic target for separation anxiety disorder.
