Seizures - Topic Overview The brain controls how the body moves by sending out small electrical signals through the nerves to the muscles. Seizures, or convulsions, occur when abnormal signals from the brain change the way the body functions. Seizures are different from person to person. Some people have only slight shaking of a hand and do not lose consciousness. Other people may become unconscious and have violent shaking of the entire body. Shaking of the body, either mild or violent, does not always occur with seizures.

- Electrical impulses allow neurons to communicate with one another. During a seizure, there is abnormal and excessive electrical activity in the brain. This can cause changes in awareness, behavior, and/or abnormal movements. This activity usually lasts only a few seconds to minutes. Epilepsy refers to a condition in which a person has a risk of recurring epileptic seizures.

- Many conditions can affect the brain and trigger a seizure, including: 1  Brain injury, either before or after birth. 2  Infections, especially meningitis and encephalitis. 3  Eating or drinking toxic substances.  Metabolic 1  problems. High fever (in children)  Genetic conditions, including tuberous sclerosis.

- Depending on where in the brain a seizure is happening, a person’s behavior may change in different ways. If too many brain cells are sending signals at the same time, it causes an overload, and a person may pass out and shake all over.

Seizures A seizure (also called a fit, spell, convulsion, or attack) is the visible sign of a problem in the electrical system that controls your brain. A single seizure can have many causes, such as a high fever, lack of oxygen, poisoning, trauma, a tumor, infection, or after brain surgery. Most seizures are controlled with medication. If your seizures occur repeatedly, then you may have the chronic disorder called epilepsy.

Common Epilepsy Causes and Seizure Triggers Seizures and Epilepsy. A seizure occurs when a burst of electrical impulses in the brain escape their normal limits. They spread to neighboring areas and create an uncontrolled storm of electrical activity. The electrical impulses can be transmitted to the muscles, causing twitches or convulsions.

Epilepsy and Seizures are Frequently Caused by a Traumatic Brain Injury Any type of traumatic brain injury or head trauma can be the cause of epilepsy or a seizure disorder. Common causes include car accidents, construction site accidents, falls as a result of dangerous and unsafe premises, and unsafe worksites. Head trauma is one of the leading causes of epilepsy and seizure disorders.

- They also can be caused by a brain tumor or other health problem affecting the brain. And anything that results in a sudden lack of oxygen or reduced blood flow to the brain can cause a seizure. In some cases, a seizure's cause is never found. Febrile seizures can happen in children younger than 6 years old.

- Epileptic: These seizures have no apparent trigger (that is, they are unprovoked), and they occur repeatedly. Epileptic seizures are called a seizure disorder or epilepsy. What causes epileptic seizures is often unknown (called idiopathic epilepsy). But they may be caused by various brain disorders, such as structural abnormalities, strokes, or tumors. In such cases, they are called symptomatic epilepsy.

- Emotional disturbances can trigger a seizure, as can hypoglycemia and hyperglycemia. People with the tendency to have seizures are more likely to have one triggered by fluctuations in blood glucose levels, but the reverse is not necessarily true.If a person is not prone to seizures, a swing in glucose levels typically would not cause a seizure.eople with the tendency to have seizures are more likely to have one triggered by fluctuations in blood glucose levels, but the reverse is not necessarily true.

- Just one breakthrough seizure, which is when someone whose seizures are usually controlled by epilepsy drugs has an unexpected seizure, is devastating for the individual and may cause serious injury and harm, rob someone of their driving licence and affect their job.

Common Epilepsy Causes and Seizure Triggers Epilepsy is a general term for the tendency to have seizures. Epilepsy is usually diagnosed only after a person has had more than one seizure. When identifiable, the causes of epilepsy usually involve some form of injury to the brain. For most people, though, epilepsy's causes aren't known.

- 2 1 What Is a seIzure? A seizure is a temporary loss of control often, but not always, accompanied by convulsions, unconsciousness or both. Most common are epileptic seizures, or seizures caused by sudden abnormal electrical discharges in the brain. Non-epileptic seizures, on the other hand, are not accom-panied by abnormal electrical discharges. They have been previously called pseudoseizures, but that term is mislead-ing. These seizures are quite real, and people who have them do not have conscious, voluntary control over them.

For more information, see the topic Epilepsy. A seizure can be a symptom of another health problem, such as: 1  A rapidly increasing fever (fever seizure). 2  An extremely low blood sugar level in a person who has diabetes.

Epilepsy and Seizures Focal seizures take place when abnormal electrical brain function happens in one or more areas of one side of the brain. Focal seizures may also be called partial seizures. With focal seizures, particularly with complex focal seizures, a person may experience an aura, or warning, before the seizure happens. The most common aura involves feelings, such as deja vu, impending doom, fear, or a feeling of great happiness or well-being.

Epileptic seizure Seizures can also occur in people who do not have epilepsy for various reasons including brain trauma, drug use, elevated body temperature, hypoglycemia (low blood sugar levels) and hypoxia (low levels of oxygen to the brain). Additionally, there are a number of conditions that look like epileptic seizures but are not.

Seizures Seizures happen when brain cells fire or “talk” too much, temporarily disrupting the brain’s normal electrical signals. They’re quite common, especially in infants and young children, and they have a wide range of causes. Certain seizures are easy to recognize (jerking, twitching, stiffness), while others don’t have any outward signs.

Epilepsy - overview Epilepsy occurs when permanent changes in the brain cause it to be too excitable or irritable. As a result, the brain sends out abnormal signals. This leads to repeated, unpredictable seizures. (A single seizure that does not happen again is not epilepsy.) Epilepsy may be due to a medical condition or injury that affects the brain. Or the cause may be unknown (idiopathic).

- Generalized seizures are produced by electrical impulses from throughout the entire brain; partial seizures are produced (at least initially) by electrical impulses in a relatively small part of the brain. The part of the brain generating the seizures is sometimes called the focus.

- These seizures can occur if you have epilepsy, which is a condition that causes repeated seizures. This type of seizure happens on only one side of the brain. As a result, one side of the body is affected during a seizure.

- Epilepsy is a disorder of the nervous system. 1  Epilepsy causes sudden, intense bursts of electrical activity in the brain. These bursts cause seizures, which may affect: 2  Muscle control. 3  Movement. 4  Speech. 5  Vision. 6  Awareness.

Causes of Seizures There can be number of reasons why someone has a seizure. In fact, anything that disturbs the normal pattern of nerve cell activity in the brain -- from illness to abnormal brain development -- can cause seizures. Some possible causes of seizures may include: 1  Fever. 2  Chemical imbalance. 3  Medical conditions. 4  Trauma. 5  Developmental problems. 6  Poisoning.

What Can Trigger a Dog to Have a Seizure? Quick Answer. Poison, liver disease, low or high blood sugar, and kidney disease are some common causes that can trigger seizures in dogs, according to WebMD. Anemia, head injury, an electrolyte problem and stroke may also lead to seizures. Keep Learning.

- Best Answer: Yes, Some computer or video games can cause seizures because of the flashing lights. They send your brain into sort of a electric shock and you can have a seizure. Here's an article that explains it better: http://www.jimsokolove.com/other/video-g...
