Epilepsy Kentville - The term epilepsy is derived from the Ancient Greek word that means "seizure." It is a common neurological disorder that is defined by seizures. These seizures are signs or transient symptoms, indications of abnormal, excessive or hyper-synchronous neuronal activity within the brain. Epilepsy usually occurs in young children or those individuals who are more than the age of sixty five, though, it can take place at whatever time. Throughout the globe, more than fifty million people have epilepsy. About 2 out of every 3 cases are discovered in developing nations. Epileptic seizures can likewise 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 treated this way. More than thirty percent of individuals with epilepsy do not have seizure control even on the best accessible medications. In many situations, an operation could be considered difficult. In numerous cases, not all epilepsy syndromes are considered permanent. Some types are confined to certain phases of childhood.
The disorder of epilepsy must not be just considered one single disorder. However, it should be noted as a syndrome with variously divergent signs which involve episodic abnormal electrical activity in 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.
On to the extend in which part of consciousness is affected, partial seizures are further divided. If it is unaffected for instance, then it is considered a simple partial seizure. Otherwise, it is referred to as a complex partial or complex psychomotor seizure. Secondary generalization is the term when a partial seizure may spread within the brain. Generalized seizures comprise loss of consciousness and are divided according to the effect on the body. These consist of atonic, tonic clonic or grand mal, myoclonic, clonic or tonic or petit mal seizures.
Sometimes children can exhibit certain behaviours that are easily mistaken for epileptic seizures that are not really caused by epilepsy. These behaviours comprise: inattentive staring, benign shudders, self gratification behaviours like nodding and rocking, head banging, conversion disorder, that is jerking and flailing of the head often in response to extreme personal stress as such will incur in a case of physical abuse. Conversion disorder has the ability to be distinguished from epilepsy since the episodes do not comprise self-injury, incontinence or happen during sleep.
Just as there are types of seizures, there are lots of various types of epilepsy syndromes. The classifications include data about the episodes and about the patient, in addition to the seizure kind. It even includes clinical features and likely causes such as behaviour during the seizure.
There are over forty various types of epilepsy consisting of: frontal lobe epilepsy, Landau-Kleffner syndrome, juvenile myoclonic epilepsy, childhood absence epilepsy, infantile spasms, LennoxGastaut syndrome, limbic epilepsy, status epileptic, abdominal epilepsy, Rett syndrome, limbic epilepsy, temporal lobe epilepsy, photosensitive epilepsy, Jacksonian seizure disorder, and Lafora disease, among others.
Every kind of epilepsy would have its own EEG findings, typical age of onset, unique combination of seizure type, own types of prognosis and treatment. The classification that is most common divides epilepsy syndromes by distribution of seizures and by location. This is determined by how the seizures appear, by EEG and by cause. Syndromes are divided into epilepsies of unknown localization, generalized epilepsies and localization-related epilepsies.
Localization-related epilepsies are normally known as partial or focal epilepsies. These variations have an epileptic focus, that is a small portion of the brain which drives the epileptic response. In contrast, generalized epilepsies occur from numerous 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 happen from more widespread circuits or from a part of the brain.
