what are Seizures?

Answer 1

A seizure is a temporary abnormal electro-physiologic phenomenon of the brain, resulting in abnormal synchronization of electrical neuronal activity. It can manifest as an alteration in mental state, tonic or clonic movements, convulsions, and various other psychic symptoms (such as déjà vu or jamais vu). It is caused by a temporary abnormal electrical activity of a group of brain cells. The medical syndrome of recurrent, unprovoked seizures is termed epilepsy, but some seizures may occur in people who do not have epilepsy.

Argh, someone beat me to it.

Answer 2

Seizures are caused by abnormal electrical discharges in the brain. Symptoms may vary depending on the part of the brain that is involved, but seizures often cause unusual sensations, uncontrollable muscle spasms, and loss of consciousness.

Some seizures may be the result of a medical problem. Low blood sugar, infection, a head injury, accidental poisoning, or drug overdose can cause a seizure. A seizure may also be due to a brain tumor or other health problem affecting the brain. In addition, anything that results in a sudden lack of oxygen to the brain can cause a seizure. In some cases, the cause of the seizure is never discovered.

When seizures recur, it may indicate the chronic condition known as epilepsy.

Febrile seizures, relatively common in kids younger than 5 years old, can occur when a child develops a high fever, usually with the temperature rising rapidly to 102° Fahrenheit (38.9° Celsius) or more. While terrifying to parents, these seizures are usually brief and rarely cause any problems, unless the fever is associated with a serious infection, such as meningitis. A child who has a febrile seizure is not more likely to develop epilepsy.

If Your Child Has a Seizure
A child who's having a seizure should be placed on the ground or floor in a safe area. Remove any nearby objects. Loosen any clothing around the head or neck. Do not try to wedge the child's mouth open or place an object between the teeth, and do not attempt to restrain movements. Once the seizure seems to have ended, roll your child onto his or her side.

Call emergency medical services immediately if your child:

has difficulty breathing
turns bluish in color
has sustained a head injury
seems ill
has a known heart condition
has never had a seizure before
might have ingested any poisons, medications, etc.
If your child has previously had seizures, call emergency services if the seizure lasts more than 5 minutes, or if the seizure is different or unusual.

If your child is breathing normally and the seizure lasts just a few minutes, you can wait until it has subsided, then call your doctor.

Following the seizure, your child will probably fall into a deep sleep (this is called the postictal period). This is normal, and you should not try to wake your child. Do not attempt to give food or drink until your child is awake and alert.

For a child who has febrile seizures, the doctor may suggest that you give fever-reducing medicine (such as ibuprofen or acetaminophen) to control the fever and prevent seizures from recurring. Your doctor may also recommend sponging your child with lukewarm water to help cool him or her down.

Following a seizure — particularly if it is a first or unexplained seizure — call your doctor or emergency medical service for instructions. Your child will usually need to be evaluated by a doctor as soon as possible.

Answer 3

Most seizures usually has a specific locus or location on one side of the brain. The two hemispheres more or less "mirror images".
If damaged cells in the left hemisphere cause abnormal electrical activity in near by cells and send an exited message to their mirror image cells in the right hemisphere. The mirror image cells are stimulated to fire by this abnormal input, and feed an exited message back to the right hemisphere soon the whole brain on fire with neural excitation and a seizure results. In some severe cases, cutting callosum "cuts the feed back loop" and reduces the likelihood of a seizure.

Answer 4

a misfire in the brain. Nerves aren't responding to each other effectivly and it cause the brain (the body's motherboard) to short circuit and thus the body jerks and spasms some are severe and others are very mild and stay constantly. Some professionals call these types of seizures ticks. But yeah, a seizure is a short circuit in the brain basically.

Answer 6

A seizure is a sudden change in behavior characterized by changes in sensory perception (sense of feeling) or motor activity (movement) due to an abnormal firing of nerve cells in the brain. Epilepsy is a condition characterized by recurrent seizures that may include repetitive muscle jerking called convulsions.

Answer 7

a seizure is an electronic shock in the bran that creates muscle spasims in and throughout the body therefore seizing your body, givin the mane

Answer 8

Where your brain stops controlling your muscles and sends random signals to them to cause spasms.

Answer 9

When a person looses compleate controll of their body.

Answer 10

electrical shorts in your brain.
