The cause is not known. [8] There are some common symptoms, such as onset after a nonspecific febrile illness, gastrointestinal illness, or upper respiratory infection. This prior illness is often cleared 1–14 days prior to the person's first seizures.
Febrile seizures are due to fevers, [12] usually those greater than 38 °C (100.4 °F). [16] The cause of the fevers is often a viral illness. [1] The likelihood of a febrile seizure is related to how high the temperature reaches. [1] [6] Some feel that the rate of increase is not important [1] while others feel the rate of increase is a risk ...
Approximately 40% of children who experience a febrile seizure will have another one. [26] In those with epilepsy, fever can trigger a seizure. Additionally, in some, gastroenteritis, which causes vomiting and diarrhea, can lead to diminished absorption of anticonvulsants, thereby reducing protection against seizures. [27]
Dravet syndrome (DS), previously known as severe myoclonic epilepsy of infancy (SMEI), is an autosomal dominant genetic disorder which causes a catastrophic form of epilepsy, with prolonged seizures that are often triggered by hot temperatures or fever. [1] It is very difficult to treat with anticonvulsant medications.
Syndromes are characterized into 4 groups based on epilepsy type: [1] a. Generalized onset epilepsy syndromes. These epilepsy syndromes have only generalized-onset seizures and include both the idiopathic generalized epilepsies (specifically childhood absence epilepsy, juvenile absence epilepsy, juvenile myoclonic epilepsy and epilepsy with generalized tonic- clonic seizures alone), as well as ...
Status epilepticus (SE), or status seizure, is a medical condition with abnormally prolonged seizures.It can have long-term consequences, [3] manifesting as a single seizure lasting more than a defined time (time point 1), or 2 or more seizures over the same period without the person returning to normal between them.
A simple febrile seizure is generalized, occurs singularly, and lasts less than 15 minutes. [19] A complex febrile seizure can be focused in an area of the body, occur more than once, and lasts for more than 15 minutes. [19] Febrile seizures affect 2–4% of children in the United States and Western Europe. It is the most common childhood ...
The risk of sudden death in young adults with epilepsy is increased 20-40-fold compared to the general population. [32] [33] [20] SUDEP is the number one cause of epilepsy-related death in people with pharmacoresistant epilepsy. [20] Children with epilepsy have a cumulative risk of dying suddenly of 7% within 40 years. [20]
