Epilepsy Brandon - The word epilepsy comes from the Ancient Greek word which translates to "seizure." It is a common neurological disorder which is defined by seizures. These seizures are indications or transient symptoms, indications of excessive, abnormal or hyper-synchronous neuronal activity in the brain. Epilepsy normally occurs in young children or those people who are over the age of sixty five, however, it could occur at whatever time. Across the world, over fifty million people have epilepsy. Roughly 2 out of every 3 cases are discovered in developing nations. Epileptic seizures can likewise result as a consequence of brain surgery and patients recovering from such surgery could experience them.
Normally, epilepsy is controlled with medication even though it is not commonly treated this way. More than thirty percent of individuals with epilepsy do not have seizure control even on the best available medications. In lots of cases, surgery can be considered difficult. In many cases, not all epilepsy syndromes are considered permanent. Several kinds are confined to particular phases of childhood.
Epilepsy should not be considered as a single disorder, but instead as a syndrome with variously divergent symptoms which all involve episodic abnormal electrical activity within the brain. Seizure types are organized initially based on 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 example, then it is considered a simple partial seizure. Otherwise, it is called a complex psychomotor or complex partial seizure. Secondary generalization is the term when a partial seizure may spread within the brain. Generalized seizures include loss of consciousness and are divided according to the effect on the body. These comprise atonic, tonic clonic or grand mal, tonic or clonic, myoclonic or petit mal seizures.
Kids would sometimes exhibit certain behaviours which are easily mistaken for epileptic seizures, yet they are not really caused by epilepsy. These behaviours consist of: inattentive staring, benign shudders, self gratification behaviours like nodding and rocking, head banging, conversion disorder, which is flailing and jerking of the head often in response to severe personal stress as such will incur in a situation of physical abuse. Conversion disorder could be distinguished from epilepsy since the episodes do not involve self-injury, incontinence or take place during sleep.
There are many kinds of epilepsy syndromes just as there are types of seizures. Classifying epilepsy comprises more facts about the patient and the episodes, as well as the seizure type alone. It likewise comprises expected causes and clinical features like for instance behaviour during the seizure.
There are over 40 various kinds of epilepsy consisting of: frontal lobe epilepsy, Landau-Kleffner syndrome, juvenile myoclonic epilepsy, childhood absence epilepsy, LennoxGastaut syndrome, infantile spasms, status epilepticus, limbic epilepsy, abdominal epilepsy, Rett syndrome, limbic epilepsy, temporal lobe epilepsy, photosensitive epilepsy, Jacksonian seizure disorder, and Lafora disease, among others.
Each and every different epilepsy kind presents with its own EEG findings, normal age of onset, unique combination of seizure kind, own kinds of prognosis and treatment. The most common classification of the different kinds 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 usually referred to as focal or partial epilepsies. These variations have an epileptic focus, which is a tiny part of the brain that drives the epileptic response. In contrast, generalized epilepsies happen from various independent foci and are referred to as multifocal epilepsies. These could comprise epileptic circuits which affect the entire brain. At this time it has not been determined whether epilepsies of unknown localization arise from a portion of the brain or from more widespread circuits.
