Cognitive control deficits in pediatric frontal lobe epilepsy

Area of Science:

• Neuroscience
• Pediatric Neurology
• Cognitive Psychology

Background:

• Executive dysfunction and behavioral issues are prevalent in children with epilepsy.
• Inhibition and shifting, crucial for cognitive control, are associated with behavioral problems and linked to frontal lobe function.

Purpose of the Study:

• To determine if children with frontal lobe epilepsy (FLE) exhibit deficits in inhibition and shifting.
• To explore the relationship between these cognitive deficits and behavioral problems in children with FLE.

Main Methods:

• Utilized the Stroop Color Word Test and a digital Wisconsin Card Sorting Test (WCST) to assess inhibition and shifting.
• Employed parent-reported questionnaires, including the Behavioral Rating Inventory for Executive Function (BRIEF) and Child Behavior Checklist (CBCL), to evaluate executive functions and behavior.

Main Results:

• Approximately 20% of children demonstrated impaired inhibition on the Stroop test, while 60% exhibited shifting difficulties on the WCST.
• Parental reports indicated executive control and behavioral deficits in about one-third of the participants.
• A correlation was observed between daily life behavioral problems and executive function deficits in inhibition and shifting (BRIEF).

Conclusions:

• Children with frontal lobe epilepsy frequently experience deficits in cognitive control, specifically inhibition and shifting.
• These executive function impairments appear to be associated with observable behavioral problems in daily life.
• While specific tests showed deficits, correlations between objective tests and subjective reports were limited, except for inhibition and perseverative errors.
