Seizures are paroxysmal events caused by abnormal, excessive, hypersynchronous discharges from an aggregate of neurons in the central nervous system. Epilepsy describes a condition in which a chronic, underlying process produces recurrent seizures.

Seizures are paroxysmal events caused by abnormal, excessive, hypersynchronous discharges from an aggregate of neurons in the central nervous system. Epilepsy describes a condition in which a chronic, underlying process produces recurrent seizures. It can be caused by anything that disturbs the normal pattern of neuron activity. Illness, brain damage, and abnormal brain development, for example, can all lead to seizures. Epilepsy may also result from changes in non-neuronal brain cells called glia. These cells regulate concentrations of chemicals in the brain that can affect neuronal signaling.
