What is a seizure?
Epilepsy is the collective term for a large group of anatomical and functional disorders of the brain that are characterized by repeated seizures.
In simple terms a seizure happens when ordinary brain activity is suddenly disrupted. A seizure can be described as an internal electrical storm. It is the consequence of abnormal, excessive discharges of nerve cells. It is this sudden unexpected loss of control that accounts for many of the misconceptions and the prejudice associated with epilepsy. Seizures are the symptoms of the disorder they are not the disorder itself.
How the brain works.
The brain is the control center for the body. It is made up of millions of cells, called neurons, which are constantly transmitting and receiving messages enabling our bodies to work properly. If some of these brain cells malfunction, for any reason, the messages can become disorganized and a seizure may result. The type of seizure a person has will depend on where in the brain the malfunction occurs. The seizure may take the form of a loss of consciousness, involuntary movements, a change in behaviour or a combination of all these.
