Epilepsy Norfolk - Epilepsy is an ancient Greek word that literally means "seizure." This common neurological disorder is typified by seizures which are generally symptoms or transient signs of excessive, abnormal or hyper-synchronous neuronal activity in the brain. Epilepsy typically happens in young kids or those individuals who are over the age of 65, although, it could happen at whichever time. All around the world, more than 50 million people have epilepsy. About 2 out of every 3 cases are discovered in developing nations. Epileptic seizures could even result as a consequence of brain surgery and people recovering from such surgical procedure could experience them.
The condition of epilepsy is generally controlled with medication, although it is not treated in this manner. Even on the best medications, more than 30% of people with epilepsy do not have seizure control. In a lot of situations, a surgical procedure could be considered difficult. In many cases, not all epilepsy syndromes are considered lifelong. Various kinds are confined to particular stages 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 symptoms that involve episodic abnormal electrical activity within the brain. Seizure kinds 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.
Partial seizures are then further divided on the extent to which area of the consciousness is affected. For instance, if it is unaffected, then it is considered a simple partial seizure, whereas otherwise, 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 involve loss of consciousness and are divided based on the effect on the body. These include atonic, tonic clonic or grand mal, tonic or clonic, myoclonic or petit mal seizures.
Kids will sometimes exhibit some behaviours which are easily mistaken for epileptic seizures, yet they are not really caused by epilepsy. These behaviours include: benign shudders, inattentive staring, self gratification behaviours including rocking and nodding, head banging, conversion disorder, which is jerking and flailing of the head usually in response to intense personal stress as such will incur in a case of physical abuse. Conversion disorder can be distinguished from epilepsy because the episodes do not comprise self-injury, incontinence or occur during sleep.
Just as there are types of seizures, there are lots of various kinds of epilepsy syndromes. The classifications include data regarding the patient and about the episodes, in addition to the seizure kind. It also includes clinical features and likely causes like for instance behaviour during the seizure.
There are over 40 various kinds of epilepsy comprising: frontal lobe epilepsy, Landau-Kleffner syndrome, juvenile myoclonic epilepsy, childhood absence epilepsy, infantile spasms, LennoxGastaut syndrome, limbic epilepsy, status epileptic, abdominal epilepsy, Rett syndrome, temporal lobe epilepsy, limbic epilepsy, Jacksonian seizure disorder, Lafora disease and photosensitive epilepsy, amongst others.
Every different epilepsy type presents with its own EEG findings, normal age of onset, unique combination of seizure type, own types of prognosis and treatment. 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 EEG and by cause. Syndromes are divided into localization-related epilepsies, epilepsies of unknown localization and generalized epilepsies.
Localization-related epilepsies are normally referred to as focal or partial epilepsies. These variations have an epileptic focus, which 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 could include epileptic circuits that affect the entire brain. At this time it has not been determined whether epilepsies of unknown localization happen from more widespread circuits or from a portion of the brain.
