Key result
Long-term carbamazepine cuts seizures ~87% and restores cognition in a Kcnq2-DEE mouse model.
Why the study?
The effect of carbamazepine on neurodevelopmental outcomes in KCNQ2 developmental and epileptic encephalopathy remains debated.
Does long-term oral carbamazepine reduce seizures and improve cognitive abilities in a mouse model of Kcnq2 developmental and epileptic encephalopathy?
Does long-term oral carbamazepine reduce seizures and improve cognitive abilities in a mouse model of Kcnq2 developmental and epileptic encephalopathy?
Absolute Event Rate: 8.3% vs 61.5%
Long-term carbamazepine treatment effectively reduces seizures and restores cognitive abilities in a mouse model of Kcnq2 developmental and epileptic encephalopathy, correlating with brain accumulation of carbamazepine-epoxide.

Preclinical efficacy in Kcnq2-DEE mice warrants caution in patients; leaves open translation to human trials.
Louis et al. (2025) studied KCNQ2 developmental and epileptic encephalopathy (n=25). Carbamazepine vs. Vehicle was evaluated on Seizures. Long-term treatment with carbamazepine reduced seizures (8.3% vs 61.5%) and restored cognitive abilities in a mouse model of Kcnq2-DEE.
