What causes electrical activity in the brain do have a seizure?

There is constant electrical activity in the brain. A seizure can occur when an increased amount of electrical activity happens. For different people the actual reasons also differ. So there is no single or simple answer to the question. Different people have different triggers or their seizures.
Sometimes it can also be because of slight damage to an area of the brain, though that does not necessarily mean that the person is brain damaged or is in some way retarded. Neither are they mentally ill as epilepsy is a physical not mental illness. So someone can have a slight piece of damage on their brain but it does not affect them in any way in their ordinary lives, except that they may get seizures.
People often associate flashing lights with seizures, although less than 5% of people who have seizures are in any way affected by flashing lights, but have other causes for their seizures. Stress can be a cause. People may have seizures because of some other health factor that affects their brain, like if they had suffered a head injury or if they had some other physical problem with their brain, like if they had a tumour. So there are many reasons why electrical activity in the brain could be disrupted.

What causes abnormal electrical activity in the brain?
It can cause a seizure.
What is seizure in human brain?
In everyone's brain there is constant electrical activity happening. A seizure is caused when there is an abnormal pattern or disruption in this activity. You could almost say it is like an electrical storm in the brain. There are many reasons for this.
What kind disability is epilepsy?
No. It is a condition where someone has a tendency to have seizures. Why this happens varies from person to person. There are many forms of Epilepsy and many causes. But it is not a disease. It is not infectious or anything like that.
Do you have an electrical storm inside of our brains when we are having a seizure?
That is a simple analogy or what is happening during a seizure. There is constant electrical activity in the brain. When it gets disrupted a bit, a person can have a seizure.
If the doctor says you have very little brain activity how do you have seizures?
There is constant electrical activity in everyone's brain at all times. When a seizure happens it is because there is a sudden increase in electrical activity, like a storm or power surge. That soon passes and electrical activity returns to normal and the seizure ends. So if when someone with epilepsy is examined at a time they are not having a seizure, then their brain's electrical activity will appear to be normal. To test for epilepsy what is sometimes done is to expose the brain to known triggers for seizures to see if there is a change in the electrical activity so that doctors can find out what causes an particular person to have seizures. Different people will have different causes for their seizures. So if the right trigger is not used during an examination, the person will still have normal brain activity. That does not mean that they don't have epilepsy and won't get seizures. It just may mean that their particular trigger wasn't one of those that were tried on them. As there are many of them, it is not possible to test for them all in one examination.
What is the difference between a seizure and a stroke?
Stroke= Blood clots Seizure= Brain Nerve Malfunctions -Stroke accures when blockage in the brain that snaps or breaks. -Seizures accure when a number of disorders take place and errupt. Pretty, right?:(
What is an seizure that involves the entire body?
It is called a Grand Mal seizure. It is caused by abnormal electrical activity in the brain. It is characterized by violent muscle contractions and unconsciousness.
Is an epileptic fit due to a over load of electicity made by the body?
It is an unusual level of electrical activity in the brain. There is constant electrical activity in the brain. If it is disrupted or an extra amount of it happens it may affect the working of the brain temporarily and the result is a seizure.
What is an epileptic fit?
An epileptic seizure is usually caused by some electrical activity in the brain. We all have electrical activity in the brain. If there is an excessive amount, this can cause an epileptic seizure. This can cause the person not to feel well, possibly lose conciousness, and have unusual physical activity because their brain is not working properly. Some physical activity could be very minor, like small movements or could be much larger like physical jolting of parts of the body. A seizure will usually not last very long and the person will soon return to normal.
What causes convulsions?
Convulsions/seizures are caused by abnormal electrical activity in the brain. For a bit of background, the brain is part of the central nervous system, which controls and 'instructs' the body on what to do. The brain sends these instructions out using electrical impulses and signals. If the brain becomes confused, for whatever reason, the electrical impulses may begin to send abnormal impulses to the wrong places and via the incorrect neurons. This causes the body to get confused and results in abnormal twitching and convulsing. People with a medical condition called epilepsy have an abnormal brain electrical activity giving rise to epileptic seizures. Seizures/convulsions can also be caused by a brain tumour or another nervous system disorder. It is vital every seizure is reported to your medical practitioner. If the seizure last for longer than normal, or if it is your first seizure, seek urgent medical assistance or phone for an emergency ambulance.
Can a seizure cause a T.I.A.?
A seizure is caused by excessive electrical activity in the brain. A transient ischaemic attack is due to a problem in the blood supply to the brain. They are two very different kinds of problems. A seizure would not cause a problem in the blood supply to the brain and so it would not cause a TIA.
What is the Primary etiology of seizure?
Primary etiology of seizure is any form of brain injury. When the electrical impulses escape their limit in the brain, this will cause seizure.
