Seizures

Secondary seizures; Seizure - secondary; Convulsions; Epileptic seizure

A seizure is the physical changes in behavior that occurs during an episode of specific types of abnormal electrical activity in the brain.

The term "seizure" is often used interchangeably with "convulsion." During convulsions a person has uncontrollable shaking that is rapid and rhythmic, with the muscles contracting and relaxing repeatedly. There are many different types of seizures. Some have mild symptoms without shaking.

Seizures

Having a brain seizure can be a terrifying experience. If you have a seizure, there was a problem with too much uncoordinated electrical activity in your brain. In general, a seizure is when too many of your brain cells become excited at the same time. There are two different types of seizures, generalized and partial. With a generalized seizure, your brain has abnormal electrical activity on both sides of your brain. Partial seizures happen when electrical activity surges in one part of your brain. Seizures can happen for many reasons; It may be from high levels of salt or sugar in your blood; brain injury from a stroke or head injury brain problems you are born with or perhaps a brain tumor. Dementia, such as Alzheimer's disease, high fever or illnesses or infections that hurt your brain. Illegal drug use or withdrawal from alcohol or drug use can cause seizures as well. So, what are the signs that someone is having a seizure? Some people with seizures may have simple staring spells, while others have violent, uncontrollable shaking and loss of consciousness. Some people will see flashing lights, others may hallucinate. Some people may have strange sensations, such as tingling, smelling an odor that isn't really there, or emotional changes. Most people who have a seizure for the first time will go to the emergency room. The doctor will do tests to rule out medical causes, such as a stroke. You may have blood tests, CT or MRI scans of your head, or a spinal tap. Treatment depends on the cause of your seizure. For example, if a seizure was caused by fever, treatment will focus on bringing the fever down. Your doctor may send you home with some medicines to help you avoid having more seizures if there is reason to think you are at continued risk of seizures. You should get plenty of sleep and try to keep as regular a schedule as possible, and try to avoid too much stress. Most people with seizures can have a very active lifestyle. Plan ahead for the possible dangers of a certain activity. Avoid any activity where loss of consciousness would be dangerous until it is clear that seizures are unlikely to occur again.
Convulsions - first aid - series

1. When a seizure occurs, the main goal is to protect the person from injury. Try to prevent a fall by laying the person on the ground in a safe area. The area should be cleared of furniture or other sharp objects. 2. Cushion the person's head. 3. Loosen tight clothing, especially around the neck.
CT scan of the brain

A CT or CAT scan (computed tomography) is a much more sensitive imaging technique than X-ray, allowing high definition not only of the bony structures, but of the soft tissues. Clear images of organs such as the brain, muscles, joint structures, veins and arteries, as well as anomalies like tumors and hemorrhages may be obtained with or without the injection of contrasting dye.
Head MRI

MRI stands for magnetic resonance imaging. It allows imaging of the interior of the body without using x-rays or other types of ionizing radiation. An MRI scan is capable of showing fine detail of different tissues of the head.
