Individuals with EB simplex can live seizure originated and how much of the brain is involved. Epilepsy is a chronic (persistent) disorder of the Generalized (also called tonic-clonic) seizures last nervous system. The primary symptoms of this disease about two minutes and are the result of abnormal electri- are periodic or recurring seizures that are triggered by cal activity that spreads out over both sides or hemi- sudden episodes of abnormal electrical activity in the spheres of the brain. The patient will usually lose con- functions or activities that are under the control of the sciousness and fall during the episode. This is followed by strong, rhythmic muscular contractions (convulsions) of the “clonic” phase. Seizures can involve a combination of sensa- muscles, causing the skin to develop a bluish tinge due to tions, muscle contractions, and other abnormal body lack of oxygen. Seizures may appear spontaneously—without any apparent cause—or can be triggered by a specific Epileptic seizures can also be classified as “com- type of stimulus such as a flashing light. Ideopathic epilepsy may be initi- seizure and then evolve into a “secondary generalized” ated by a combination of genetic and environmental episode in which the initial abnormal electrical activity factors. Patients may actually remember the physical and psychological events An epileptic seizure involves a transient (temporary) that occur during a simple seizure, such as the types of episode of abnormal electrical activity in the brain. In addition to abnormal physical symptoms, An “absence seizure” (once called ) typi- seizures can bring on emotions ranging from fear, anger, cally results in brief periods of “lack of awareness” and and rage, to joy or happiness. The patient generally may experience disorientation, spontaneous sensations of remains conscious during the seizure episode, but may sounds, smells, visions, and distorted visual perception— become absent-minded and unresponsive. Epilepsy can also be triggered by with learning, storage, and retrieval of new information. Epilepsy cases that seem to have no read- the temporal lobe of the brain can cause a serious deteri- ily identifiable cause are referred to as “idiopathic” cases oration (loss) of memory function. Seizures can damage and destroy brain In some forms of epilepsy, seizures can be triggered cells and scar tissue can develop in the section of brain by a particular mental—or cognitive—activity. Symptoms parts of the body that are affected by a seizure and the include face muscle spasms. In medical terms, this type distinctive characteristics, duration, and severity of the of epilepsy is referred to as “idiopathic localization- symptoms can distinguish each type of epilepsy. This means that seizures occur in one can experience more than one type of seizure. The nature part of the brain (in this case, the temporal lobes) and that of the symptoms depends on where in the brain the there is no apparent cause that brought on the disease. Either the fluid itself or cells from the fluid can be used for a variety of tests to obtain information about genetic disorders and other medical conditions in the fetus. Cytosine and guanine are two of the four molecules, other- wise called nucleic acids, that make up DNA. These cells are then tested for chromosome abnormalities or other genetic diseases. Changes in either the total number of chromo- somes or their shape and size (structure) may lead to physical or mental abnormalities. Its exact purpose is unknown, but it is sus- pected that the gene plays a role in brain development. Mitral valve prolapse may be detected as a heart murmur but there are usually no symptoms.
