Pediatric Stroke Impairs Theory of Mind Performance

Area of Science:

• Neuroscience
• Developmental Psychology
• Pediatric Neurology

Background:

• Childhood stroke can impact cognitive development.
• Social cognition, including theory of mind (ToM), is crucial for social interaction.
• Brain connectivity alterations are implicated in various neurological conditions.

Purpose of the Study:

• To investigate if childhood stroke affects performance on theory of mind (ToM) tasks.
• To examine the correlation between ToM task performance and resting-state brain connectivity in children with stroke.
• To identify potential neural mechanisms underlying social cognition deficits post-stroke in children.

Main Methods:

• A case-control pilot study comparing 10 children with stroke to 10 age- and gender-matched controls.
• Administration of two distinct theory of mind (ToM) tasks.
• Functional magnetic resonance imaging (fMRI) to measure resting-state functional connectivity.

Main Results:

• Children with stroke demonstrated significantly poorer performance on conative ToM tasks compared to controls.
• Elevated resting-state connectivity within the central executive network was observed in children with stroke.
• Decreased connectivity between the right and left inferior parietal lobules was noted in the stroke group.
• No significant correlation was found between resting-state activity and ToM task performance.

Conclusions:

• Childhood stroke is associated with impaired performance on specific theory of mind (ToM) tasks.
• Stroke in childhood leads to alterations in brain network connectivity, particularly in regions supporting social cognition.
• These findings suggest potential neural mechanisms affected by stroke that influence social cognition in children.
• Further research into the impact of childhood stroke on network connectivity is warranted to understand its cognitive effects.
