Our brains may ripple before remembering

A sound, a smell, a word can all flood our minds with memories of past experiences. In a study of epilepsy patients, researchers at the National Institutes of Health found that split seconds before we recall these events ...

Triangular relationship in the epileptic brain

When an epileptic seizure occurs in the brain, the nerve cells lose their usual pattern and fire in a very fast rhythm. The cause is a complex interplay of various factors. Scientists at the University of Bonn have now discovered ...

Key mechanism of epileptic seizures reported

Russian scientists investigated the changes in the temporal lobe cortex of a rat brain during prolonged epileptic seizures. Despite the complex interaction of neural signals, biologists and physicists managed to build their ...

Seizures begin with a muffle

Some patients describe epileptic seizures like an earthquake from within, starting slow and growing without their control. To a brain researcher, seizures are an electrical firestorm of neuronal activation in the brain. Now, ...

Seizure

An epileptic seizure is a transient symptom of excessive or synchronous neuronal activity in the brain. It can manifest as an alteration in mental state, tonic or clonic movements, convulsions, and various other psychic symptoms (such as déjà vu or jamais vu). The medical syndrome of recurrent, unprovoked seizures is termed epilepsy, but seizures can occur in people who do not have epilepsy.

About 4% of people will have an unprovoked seizure by the age of 80 and only 30% to 40% or according to another study 50% chance of a second one. Treatment may reduce the chance of a second one by as much as half.

The treatment of epilepsy is a subspecialty of neurology; the study of seizures is part of neuroscience. Doctors who specialize in epilepsy are epileptologists; doctors who specialize in the treatment of children with epilepsy are pediatric epileptologists.
