Seizures result from an excess of electrical current in the brain

The claim states that seizures result from an excess of electrical current in the brain. The retrieved literature broadly supports the core neurological consensus that seizures and epilepsy involve abnormal electrical activity, neuronal hyperexcitability, and excitatory imbalances (Papers 5, 6, 10, 11). Although one study nuances this by showing that individual unit firing patterns during interictal discharges are heterogeneous rather than a simple uniform mass of excitation, the overarching physiological mechanism of seizures remains fundamentally rooted in excessive and hypersynchronous electrical hyperexcitability, supporting the general accuracy of the claim.
