- Some seizures may place temporary but severe stress on the body and cause problems with the muscles, lungs, or heart. Choking, an abnormal heartbeat, or other problems may cause sudden death, though this is rare. Untreated seizures that become more severe or frequent may lead to these problems.

- It can be dangerous to be operating machinery or driving when you have a seizure. You cannot swallow your tongue during seizures. But you can choke on food, vomit, or an object in your mouth. Some seizures may place temporary but severe stress on the body and cause problems with the muscles, lungs, or heart. Choking, an abnormal heartbeat, or other problems may cause sudden death, though this is rare. Untreated seizures that become more severe or frequent may lead to these problems. One of the most dangerous complications of epilepsy is a prolonged seizure condition that can result in brain damage or death called status epilepticus. WebMD Medical Reference from Healthwise.

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).

Why Do Dogâs Have Seizures? The seizure itself can last anywhere from a few seconds to five minutes. After the seizure, a dog may appear confused and may even have a hard time seeing for a short duration. The seizure, itself, is not painful to the dog, but injury may be inflicted during the seizure, such as tongue biting or falling.

Epilepsy - overview Seizures are episodes of uncontrolled and abnormal firing of brain cells that may cause changes in attention or behavior. 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. Epilepsy may be due to a medical condition or injury that affects the brain.

Opiate Withdrawal and Seizures Seizures are symptoms of a brain problem. They happen because of sudden, abnormal electrical activity in the brain. When people think of seizures, they often think of convulsions in which a person's body shakes rapidly and uncontrollably. Not all seizures cause convulsions. There are many types of seizures and some have mild symptoms. Seizures fall into two main groups. Focal seizures, also called partial seizures, happen in just one part of the brain. Generalized seizures are a result of abnormal activity on both sides of the brain. Read more on MedlinePlus.gov.

- People have seizures when the electrical signals in the brain misfire. These overactive electrical discharges disrupt the brain's normal electrical activity and cause a temporary communication problem among nerve cells. Having a seizure doesn't always mean that a person has epilepsy. Seizures can be triggered in anyone under certain conditions, such as life-threatening dehydration or being severely overheated. But when a person experiences repeated seizures for no obvious reason, that person is said to have epilepsy.

Seizures and Traumatic Brain Injury One of the problems that can occur after a traumatic brain injury (TBI) is seizures. Although most people who have a brain injury will never have a seizure, it is good to understand what a seizure is and what to do if you have one. Most seizures happen in the first several days or weeks after a brain injury.

What is the difference between seizures, convulsions, epilepsy and tremors? A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain. The term seizure is often used interchangeably with convulsion.. Convulsions occur when a person's body shakes rapidly and uncontrollably. During convulsions, the person's muscles contract and relax repeatedly. There are many different types of seizures.

Seizures in Dogs: Causes, Symptoms, & What to Do The most common kind is the generalized seizure, also called a grand mal seizure. A dog can lose consciousness and convulse. The abnormal electrical activity happens throughout the brain. Generalized seizures usually last from a few seconds to a few minutes. With a focal seizure, abnormal electrical activity happens in only part of the brain. Focal seizures can cause unusual movements in one limb or one side of the body.

Caring for Dogs Who Suffer From Brain Diseases and Seizures Types of Seizures and Why They Happen. A seizure is the result of sudden and abnormal neurological activity, basically a kind of electrical storm in the brain. In humans and dogs, seizures can manifest themselves in many ways and have a multitude of causes. However, seizures are always accompanied by altered or loss of consciousness. They may last a few seconds, several minutes, or, in the worst cases, hours.

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.

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.

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.
