Epilepsy Ottawa - The term epilepsy is derived from the Ancient Greek word which means "seizure." It is a common neurological disorder which is defined by seizures. These seizures are symptoms or transient symptoms, indications of abnormal, excessive or hyper-synchronous neuronal activity within the brain. Epilepsy normally occurs in young kids or those people who are more than the age of sixty five, although, it could happen at whichever time. Across the globe, over 50 million people have epilepsy. Around 2 out of every 3 cases are discovered in developing countries. Epileptic seizures could also result as a consequence of brain surgery and patients recovering from such surgical procedure can experience them.
Generally, epilepsy is controlled with medication even if it is not normally cured this way. More than 30% of patients with epilepsy do not have seizure control even on the best available medications. In various situations, an operation could be considered difficult. In various situations, not all epilepsy syndromes are considered lifelong. Several forms 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 symptoms that involve episodic abnormal electrical activity within the brain. Seizure types are organized firstly based on whether the source of the seizure is localized as in focal or partial onset seizures or whether they are more generalized or distributed 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 known as a complex partial or complex psychomotor seizure. Secondary generalization is the term when a partial seizure could spread in the brain. Generalized seizures involve loss of consciousness and are divided according to the effect on the body. These comprise tonic clonic or grand mal, atonic, tonic or clonic, myoclonic or petit mal seizures.
Sometimes kids can exhibit some behaviours which are easily mistaken for epileptic seizures that are not really caused by epilepsy. These behaviours include: inattentive staring, benign shudders, self gratification behaviours like for example head banging, rocking and nodding, conversion disorder, that is jerking and flailing of the head often in response to intense personal stress as such will incur in a situation of physical abuse. Conversion disorder can be distinguished from epilepsy as the episodes do not comprise self-injury, incontinence or happen during sleep.
There are many kinds of epilepsy syndromes just as there are kinds of seizures. Classifying epilepsy includes more information regarding the episodes and the patient, as well as the seizure kind alone. It likewise comprises expected causes and clinical features like behaviour during the seizure.
There are over 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, photosensitive epilepsy, Jacksonian seizure disorder, and Lafora disease, among others.
Each kind of epilepsy would have its own EEG findings, usual age of onset, unique combination of seizure kind, 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 cause and by EEG. Syndromes are divided into localization-related epilepsies, epilepsies of unknown localization and generalized epilepsies.
Localization-related epilepsies are usually called partial or focal epilepsies. These variations have an epileptic focus, which is a small part of the brain that drives the epileptic response. In contrast, generalized epilepsies arise from many independent foci and are called 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 occur from more widespread circuits or from a portion of the brain.
