Seizure Disorders

What is a seizure?

Seizures are a sudden surge of electrical activity in the brain which can affect how a person appears or acts for a short time. The electrical activity is caused by complex chemical changes that occur in nerve cells. Brain cells either excite or inhibit other brain cells from sending messages. Usually there is a balance of cells that excite and those that can stop these messages. When a seizure occurs, there may be too much or too little activity, causing an imbalance between exciting and stopping activity. The chemical changes can lead to surges of electrical activity that cause seizures. Seizures are not a disease in themselves. Instead they are a symptom of many different disorders that can affect the brain. Some seizures can hardly be noticed, while others are totally disabling.

Seizures and Neurofeedback

There has been over 50 controlled studies that a special form of brain wave biofeedback now called Neurofeedback safely and effectively trains and stabilizes your brain waves. Neurofeedback is effective with treating all types of seizures. In a typical training session computerized biofeedback instrumentation detects and displays the brain waves on the computer screen. The program inhibits the slow waves while reinforcing mid-range frequencies associated with preventing seizures. Neurofeedback uses sound feedback in order to reinforce brain waves. The sound is essential to the neurons which through operant conditioning creates a more stable brain wave pattern.

EEGs of people with epilepsy look something like this:

Spike-and-slow-wave

3-second spike-and-wave (Absence or Petit Mal)

During Tonic Clonic seizure

An EEG of a person without epilepsy would look something like this:
