Eat This Not That: Etiology Of Epilepsy

Epilepsies are now described more precisely by their specific underlying etiologies. The risk of developing post-traumatic epilepsy varies with the type and severity.

Epilepsy A Family Physician Perspective

Reactive seizures and chronic epi-lepsy respectively occur in 10 and 4 of head trauma patients of all ages 5.

Etiology of epilepsy. Epilepsy is a general term for the tendency to have seizures. The relationship between genes and seizures can be very complex and genetic testing is not available yet for many forms of epilepsy. There are two main types of.

As such terminology such as idiopathic cryptogenic and symptomatic are no longer used. These are defined and subcategories are proposed. Ann Neurol 199027232.

The genetic defect may arise at a chromosomal or molecular level. Others by inborn metabolic problems or early oxygen deprivation that leads to scarring. Etiology of seizures in the elderly.

The etiology of partial epilepsies is broad and includes cortical lesions tumors developmental malformation or acute cortical damage due to trauma or stroke. Epilepsy is a chronic disease of the brain characterized by an enduring ie persisting predisposition to generate seizures unprovoked by any immediate central nervous system insult and by the neurobiologic cognitive psychological and social consequences of seizure recurrences. One or more genes may cause the epilepsy or epilepsy may be caused by the way some genes work in the brain.

Etiology and patterns of seizures in the elderly. Other epilepsies occur as a result of brain trauma stroke infection tumor or genetic susceptibility. Luhdorf K Jensen LK Plesner AM.

Seizures in elderly patients. Haemorrhagic trau-matic lesions may also produce an epileptic focus. Loiseau J Loiseau P Duche B et al.

GENETIC ETIOLOGY The concept of genetic epilepsy is that the epilepsy is as best we understand the direct result of a known or presumed genetic defect s in which seizures are the core symptom of the disorder. Trauma-induced epilepsy is becoming a larger issue as medical advances allow patients to survive more severe traumas that would have been fatal in previous generations. Epilepsy is usually diagnosed only after a person has had more than one seizure.

Head injury birth trauma cerebrovascular disease and intracranial infections neurocysticercosis or meningoencephalitis and genetic factors are the main causes of epilepsy. Some epilepsies are caused by problems in the early formation of the fetal brain. MRI is the modality of choice for epilepsy most often investigating for.

Some people with no known cause of epilepsy may have a genetic form of epilepsy. In recent years there has been a significant expansion in our understanding of the underlying etiologies of the epilepsies underpinned by advances in modern neuroimaging and genetic testing. A seizure is a sudden rush of electrical activity in the brain.

When identifiable the causes of. Epilepsy is a common neurological disorder that has a varied presentation and requires two or more unprovoked seizures at least 24 hours apart for diagnosis. Dr Daniel J Bell and Dr Henry Knipe et al.

Significant inter- and intra-country differences in incidence and prevalence exist because multiple etiologic factors are implicated. Idiopathic symptomatic provoked and cryptogenic. The incidence rate of epilepsy is higher in the developing countries than the industrialized countries.

In this scheme the etiology of epilepsy is divided into four categories. Epilepsy is a chronic disorder that causes unprovoked recurrent seizures. A survey of epileptic disorders in southwest France.

Epilepsy is a heterogeneous disorder the symptoms of which are preventable and controllable to some extent. Similarly the incidence is also higher in male than female. Many past reviews have addressed sole etiologies.

Intracranial haemorrhage accounts for 1015 of neonatal seizures 6. Still others have no apparent cause.
