Chronic pain in children: structural and resting-state functional brain imaging within a developmental perspective

Area of Science:

• Neuroscience
• Pediatric Medicine
• Medical Imaging

Background:

• Chronic pain is a significant public health issue in the US, with substantial economic costs.
• Childhood hospitalizations for chronic pain have surged nearly tenfold in the last decade.
• Novel treatment strategies for pediatric chronic pain remain limited.

Purpose of the Study:

• To review brain imaging findings in pediatric chronic pain populations.
• To synthesize structural and resting-state functional magnetic resonance imaging (fMRI) data.
• To discuss the impact of chronic pain on cortical development and identify sex differences.

Main Methods:

• Systematic review of recent brain imaging studies in pediatric chronic pain.
• Analysis of structural and resting-state fMRI data.
• Summarization of sex differences and treatment effects on cortical alterations.

Main Results:

• Brain imaging studies suggest alterations in brain structure and function in children with chronic pain.
• Potential impact of chronic pain on cortical development is being explored.
• Limited evidence exists due to small sample sizes and methodological limitations in current studies.

Conclusions:

• Brain imaging may help personalize chronic pain treatments for children by identifying underlying neural pathways.
• Further research with robust methodology is needed to establish reliable brain signatures of pediatric chronic pain.
• Identifying these brain signatures could lead to novel research and treatment strategies for childhood chronic pain.
