Epilepsy in LEAT and other brain tumors: A focused review

Of all patients with brain tumors, about 30–50% suffer from epileptic seizures. The probability of developing epilepsy is particularly high in low-grade, epilepsy-associated brain tumors (LEAT). LEATs often show a pronounced network dysfunction with extensive EEG pathologies and cognitive deficits, and the epilepsies are often difficult to treat. In high-grade brain tumors, epileptic seizures determine morbidity and quality of life. The underlying mechanisms of epileptogenesis of brain tumors are increasingly understood and raise hope for personalized therapeutic approaches. This short, focused review provides an overview of the current understanding of brain tumor-related epilepsies.
