Changes on Cognition and Brain Network Temporal Variability After Pediatric Neurosurgery.

Area of Science:

• Neuroscience
• Pediatric Neurosurgery
• Cognitive Rehabilitation

Background:

• Pediatric intracranial space-occupying lesions require attention to long-term cognitive function and brain network changes post-surgery.
• Temporal variability (TV) analysis offers insights into resting-state brain activity and rehabilitation potential.
• Limited research exists on neurosurgery's isolated effect on pediatric brain network self-repair.

Purpose of the Study:

• To investigate cognitive function and brain network alterations in children following neurosurgery for intracranial space-occupying lesions.
• To explore the self-repair capacity of brain networks and cognitive functions in pediatric neurosurgery patients.
• To utilize Temporal Variability (TV) analysis to assess postoperative changes.

Main Methods:

• Studied 35 children with intracranial space-occupying lesions.
• Performed pre- and postsurgery Magnetic Resonance Imaging (MRI) and cognitive tests.
• Applied TV analysis to brain networks and correlated imaging indicators with cognitive performance.

Main Results:

• Cognitive recovery observed around 3 months postsurgery, particularly in social cognition and nonverbal reasoning.
• TV analysis revealed increased nodal variability in visual and sensorimotor networks.
• Alterations in occipital regions correlated with improvements in social cognition and nonverbal reasoning.

Conclusions:

• Significant intrinsic repair of cognitive functions and brain networks occurs approximately 3 months postneurosurgery in children.
• Findings enhance understanding of postoperative cognitive and brain network self-repair in pediatric patients.
• Identified potential therapeutic targets for rehabilitation and a foundation for proactive surgical strategies.
