Epilepsy Prince Albert - Epilepsy is an ancient Greek term which literally means "seizure." This common neurological disorder is typified by seizures that are usually symptoms or transient indications of excessive, abnormal or hyper-synchronous neuronal activity within the brain. Epilepsy usually happens in young kids or those individuals who are more than the age of 65, however, it could happen at whatever time. All around the globe, more than 50 million people have epilepsy. Roughly 2 out of every 3 cases are discovered in developing nations. Epileptic seizures can even result as a consequence of brain surgery and individuals recovering from such operation can experience them.
Usually, epilepsy is controlled with medication though it is not usually cured this way. Over thirty percent of people with epilepsy do not have seizure control even on the best accessible medications. In many situations, surgery could be considered difficult. In numerous situations, not all epilepsy syndromes are considered permanent. Various types are confined to particular phases of childhood.
The disorder of epilepsy must not be just considered one single disorder. On the other hand, it must be noted as a syndrome with variously divergent signs which involve episodic abnormal electrical activity within the brain. Seizure kinds are organized firstly according to whether the source of the seizure is localized as in focal or partial onset seizures or whether they are more distributed or generalized seizures.
Partial seizures are then further divided on the extent to which part of the consciousness is affected. For example, if it is unaffected, then it is considered a simple partial seizure, whereas otherwise, it is called a complex partial or complex psychomotor seizure. Secondary generalization is the term when a partial seizure could spread within the brain. Generalized seizures include loss of consciousness and are divided based on the effect on the body. These comprise tonic clonic or grand mal, atonic, clonic or tonic, myoclonic or petit mal seizures.
Sometimes children may exhibit some behaviours which are easily mistaken for epileptic seizures that are not actually caused by epilepsy. These behaviours consist of: inattentive staring, benign shudders, self gratification behaviours like head banging, nodding and rocking, conversion disorder, that is flailing and jerking of the head normally in response to extreme personal stress as such would incur in a situation of physical abuse. Conversion disorder can be distinguished from epilepsy since the episodes do not involve self-injury, incontinence or occur during sleep.
There are many kinds of epilepsy syndromes just as there are kinds of seizures. Classifying epilepsy comprises more data regarding the episodes and the patient, as well as the seizure type alone. It likewise comprises clinical features and expected causes such as behaviour during the seizure.
There are more than forty various kinds of epilepsy including: Landau-Kleffner syndrome, frontal lobe epilepsy, childhood absence epilepsy, juvenile myoclonic epilepsy, LennoxGastaut syndrome, infantile spasms, status epilepticus, limbic epilepsy, Rett syndrome, abdominal epilepsy, limbic epilepsy, temporal lobe epilepsy, Lafora disease, photosensitive epilepsy and Jacksonian seizure disorder, among others.
Every different epilepsy kind presents with its own EEG findings, usual age of onset, unique combination of seizure kind, own types of treatment and prognosis. The most common classification of the different types of epilepsies divides epilepsy syndromes by distribution of seizures and by location. This is determined by how the seizures appear, by cause and by EEG. Syndromes are divided into localization-related epilepsies, epilepsies of unknown localization and generalized epilepsies.
Localization-related epilepsies are usually known as focal or partial epilepsies. These variations have an epileptic focus, that is a small part of the brain that drives the epileptic response. In contrast, generalized epilepsies happen from various independent foci and are called multifocal epilepsies. These can include epileptic circuits that affect the whole brain. At this time it has not been determined whether epilepsies of unknown localization occur from a portion of the brain or from more widespread circuits.
