Seizures information from trusted sources:
A seizure is the physical findings or changes in behavior that occur after an episode of abnormal electrical activity in the brain. See also: Generalized tonic clonic seizure Partial (focal) seizure Petit mal (absence) seizure Epilepsy Fever (febrile) convulsions (seizures in children with high fever)
Seizures occur when abnormal events in the brain trigger changes in consciousness, muscle control, and sensations. Epilepsy is a term that describes a variety of syndromes characterized by the spontaneous recurrent seizures. Epilepsy and seizure disorder are synonymous. During a seizure, brain cells suddenly start firing rapidly in an abnormal fashion.
Abnormal electrical activity in the brain triggers seizure activity. A person may have a seizure disorder (epilepsy) and require medications. Other factors such as hypoglycemia (low blood sugar), which is a diabetic reaction, may cause seizures. Meningitis or a head injury may also cause a seizure.
Grand mal seizure
A grand mal seizure also known as a tonic-clonic seizure features a loss of consciousness and violent muscle contractions. It's the type of seizure most people picture when they think about seizures in general.
