Insights
Levetiracetam (LEV) monotherapy in children with benign epilepsy with centrotemporal spikes (BECTS) showed cognitive improvements over two years. Cognitive scores in LEV-treated children with BECTS improved, unlike the control group.
Area of Science:
- Pediatric Neurology
- Epileptology
- Cognitive Neuroscience
Background:
- Benign epilepsy with centrotemporal spikes (BECTS) is a common childhood epilepsy syndrome.
- Levetiracetam (LEV) is frequently used for BECTS due to its favorable profile.
- Long-term cognitive effects of LEV in BECTS are not well-established.
Purpose of the Study:
- To evaluate cognitive changes in children with BECTS treated with LEV monotherapy over two years.
- To compare the cognitive profile of LEV-treated BECTS patients with a control group of children with specific learning disabilities.
Main Methods:
- A cohort of 20 children with BECTS on LEV monotherapy and 10 controls with learning disabilities were assessed.
- Cognitive profiles were evaluated using the Wechsler Intelligence Scale for Children - Fourth Edition (WISC-IV) at baseline and after 2 years.
- LEV blood levels and EEG were monitored; statistical analysis used Student's t-test.
Main Results:
- Children treated with LEV showed statistically significant improvements in overall cognitive abilities after 24 months.
- Specific cognitive domains including verbal skills, visual-perceptual reasoning, working memory, and processing speed improved.
- The control group's cognitive profile remained largely unchanged over the 2-year follow-up period.
Conclusions:
- LEV monotherapy in children with BECTS does not negatively impact cognitive function.
- Cognitive scores in children with BECTS treated with LEV demonstrated improvement over time.
- These findings differentiate the cognitive trajectory from that observed in children with specific learning disabilities.
Introduction:
Benign epilepsy with centrotemporal spikes (BECTS) is a common epileptic syndrome in childhood, characterized by brief and infrequent partial motor seizures, with or without generalization and mostly recurring during sleep. Because of its favorable efficacy, tolerability, and safety profile, levetiracetam (LEV) monotherapy is often administered in these patients. Long-term effects of LEV therapy and its influence on cognitive functions remain controversial.
Purpose:
This evaluated the changes in the cognitive profile of children with BECTS treated with LEV monotherapy for 2 years, compared with a control group of children with specific learning disabilities.
Method:
Our patient cohort included 20 children aged 8-14 years diagnosed as having BECTS and administered LEV monotherapy and 10 age/sex-matched controls with specific learning disabilities. All participants underwent a standardized test for assessing cognitive profile (Wechsler Intelligence Scale for Children - Fourth Edition [WISC-IV]) before drug therapy and after 2 years of treatment. Average LEV blood level and electroencephalographic (EEG) recordings were periodically monitored. Several factors such as age, sex, response to therapy, and EEG pattern changes were considered. Statistical analysis was performed using Student's t-test for paired and independent samples. p < 0.05 was considered statistically significant.
Results:
Children administered LEV for 24 months showed a mild but statistically significant improvement in overall cognitive abilities. Verbal skills, visual-perceptual reasoning, working memory, and processing speed showed slight but significant improvement. In the control group, cognitive profile remained substantially unchanged at 2-year follow-up.
Conclusions:
Not only do our data suggest a nonworsening of the cognitive profile in BECTS with LEV but, on the contrary, cognitive scores also improved over time, unlike the control group.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
