Electrical Activity In The Brain Seizure

Focal and generalized are the two types of seizures.

Electrical activity in the brain seizure.

Not all seizures cause convulsions. Seizures are changes in the brain s electrical activity. A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain. These changes can cause dramatic noticeable symptoms or in other cases no symptoms at all.

Causes of seizures include diabetic reaction low blood sugar hyperglycemia and medications. Doctors generally classify seizures as either focal or generalized based on how and where abnormal brain activity begins. 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. Whatever the brain and body can do normally can also occur during a seizure.

Watch what happens when abnormal electrical activity interrupts your normal brain function. A seizure is a sudden change in the brain s normal electrical activity. Many different things can occur during a seizure. Symptoms of seizures include lip smacking behavior staring spells.

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. A seizure is a sudden surge of 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. Focal seizures result from abnormal electrical activity in one area of your brain.

Seizures may briefly affect muscle control movement speech vision and awareness. The root condition may be epilepsy or another condition. 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 may also be classified as unknown onset if how the seizure began isn t known. Epileptic seizures are caused by unusual electrical activity in the brain. Seizures are symptoms of a brain problem. They happen because of sudden abnormal electrical activity in the brain.

Seizures epilepsy are caused by abnormal electrical activity in the brain. There are two major types of seizures. Some people experience symptoms similar to those of an epileptic seizure but without any unusual electrical activity in the brain.
