Epilepsy Windsor - Epilepsy is an ancient Greek word which literally means "seizure." This common neurological disorder is typified by seizures which are normally signs or transient signs of excessive, abnormal or hyper-synchronous neuronal activity within the brain. Epilepsy normally occurs in young kids or those people who are over the age of sixty five, although, it may happen at whatever time. Throughout the globe, more than 50 million individuals have epilepsy. Roughly 2 out of every 3 cases are discovered in developing nations. Epileptic seizures may also result as a consequence of brain surgery and people recovering from such operation could experience them.
Usually, epilepsy is controlled with medication though it is not usually cured this way. Over 30% of individuals with epilepsy do not have seizure control even on the best accessible medications. In a lot of cases, surgery can be considered difficult. In several cases, not all epilepsy syndromes are considered lifelong. Several types are confined to certain stages of childhood.
Epilepsy must not be considered as a single disorder, but instead as a syndrome with variously divergent signs which all involve episodic abnormal electrical activity in the brain. Seizure types are organized firstly based on whether the source of the seizure is localized as in partial or focal onset seizures or whether they are more distributed or generalized seizures.
On to the extend in which area of consciousness is affected, partial seizures are further divided. If it is unaffected for example, then it is considered a simple partial seizure. If not, it is called a complex psychomotor or complex partial seizure. Secondary generalization is the term when a partial seizure may spread in the brain. Generalized seizures comprise loss of consciousness and are divided based on the effect on the body. These comprise atonic, tonic clonic or grand mal, tonic or clonic, myoclonic or petit mal seizures.
Kids will at times exhibit certain behaviours which are easily mistaken for epileptic seizures, yet they are not in fact caused by epilepsy. These behaviours comprise: benign shudders, inattentive staring, self gratification behaviours including head banging, nodding and rocking, conversion disorder, which is flailing and jerking of the head often in response to intense personal stress as such would incur in a case of physical abuse. Conversion disorder has the ability to be distinguished from epilepsy because the episodes do not involve self-injury, incontinence or happen during sleep.
There are many types of epilepsy syndromes just as there are types of seizures. Classifying epilepsy comprises more information regarding the episodes and the patient, as well as the seizure type alone. It also comprises likely causes and clinical features like for instance behaviour during the seizure.
Epilepsy includes over forty various kinds, amongst which are: Landau-Kleffner syndrome, frontal lobe epilepsy, childhood absence epilepsy, juvenile myoclonic epilepsy, infantile spasms, LennoxGastaut syndrome, limbic epilepsy, status epileptic, abdominal epilepsy, Rett syndrome, limbic epilepsy, temporal lobe epilepsy, Lafora disease, photosensitive epilepsy and Jacksonian seizure disorder, amongst others.
Every different epilepsy type presents with its own EEG findings, typical age of onset, unique combination of seizure kind, own kinds of prognosis and treatment. The most common classification of the various 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 epilepsies of unknown localization, generalized epilepsies and localization-related epilepsies.
Localization-related epilepsies are normally known as focal or partial epilepsies. These variations have an epileptic focus, which is a small part of the brain which drives the epileptic response. In contrast, generalized epilepsies occur from several independent foci and are referred to as multifocal epilepsies. These could involve epileptic circuits which affect the entire brain. At this time it has not been determined whether epilepsies of unknown localization occur from a part of the brain or from more widespread circuits.
