Electrical Activity In The Brain Seizure

There are many types of seizures and some have mild symptoms.

Electrical activity in the brain seizure.

A seizure is a sudden change in the brain s normal electrical activity. A seizure is a sudden surge of electrical activity in the brain. Epileptic seizures are caused by unusual electrical activity in the brain. Seizures may briefly affect muscle control movement speech vision and awareness.

Seizures may also be classified as unknown onset if how the seizure began isn t known. When people think of seizures they often think of convulsions in which a person s body shakes rapidly and uncontrollably. The symptoms of a severe seizure include. Seizures are changes in the brain s electrical activity.

These changes can cause dramatic noticeable symptoms or in other cases no symptoms at all. Focal and generalized are the two types of seizures. An eeg records the electrical activity of your brain via electrodes affixed to your scalp eeg results show changes in brain activity that may be useful in diagnosing brain conditions especially epilepsy and other seizure disorders. Seizures are symptoms of a brain problem.

Some people experience symptoms similar to those of an epileptic seizure but without any unusual electrical activity in the brain. The root condition may be epilepsy or another condition.

Seizures epilepsy are caused by abnormal electrical activity in the brain. When this happens it is known as a non epileptic seizure nes. Symptoms of seizures include lip smacking behavior staring spells. Doctors generally classify seizures as either focal or generalized based on how and where abnormal brain activity begins.

A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain. There are two major types of seizures. They happen because of sudden abnormal electrical activity in the brain. During a seizure brain cells fire uncontrollably at up to four times their normal rate temporarily affecting the way a person behaves moves thinks or feels.

The term seizure is often used interchangeably with convulsion during convulsions a person has uncontrollable shaking that is rapid and rhythmic with the muscles contracting and relaxing repeatedly.
