Epilepsy Truro - The term epilepsy comes from the Ancient Greek word which means "seizure." It is a common neurological disorder which is defined by seizures. These seizures are indications or transient signs of excessive, abnormal or hyper-synchronous neuronal activity in the brain. Epilepsy normally happens in young children or those individuals who are more than the age of sixty five, however, it could happen at any time. Across the globe, over 50 million individuals have epilepsy. Around 2 out of every 3 cases are discovered in developing nations. Epileptic seizures could likewise result as a consequence of brain surgery and patients recovering from such surgery may experience them.
The condition of epilepsy is usually controlled with medication, even though it is not treated in this manner. Even on the best medications, more than thirty percent of patients with epilepsy do not have seizure control. In numerous cases, a surgical procedure can be considered difficult. In numerous cases, not all epilepsy syndromes are considered lifelong. Some types are confined to particular 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 within the brain. Seizure kinds are organized primarily 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 referred to as a complex partial or complex psychomotor seizure. Secondary generalization is the term when a partial seizure can spread within the brain. Generalized seizures involve loss of consciousness and are divided according to the effect on the body. These consist of atonic, grand mal or tonic clonic, tonic or clonic, myoclonic or petit mal seizures.
At times children can exhibit some behaviours which are easily mistaken for epileptic seizures that are not really caused by epilepsy. These behaviours consist of: benign shudders, inattentive staring, self gratification behaviours including head banging, rocking and nodding, conversion disorder, which is flailing and jerking of the head usually in response to severe 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 occur during sleep.
Just as there are kinds of seizures, there are many various kinds of epilepsy syndromes. The classifications comprise data about the episodes and about the patient, in addition to the seizure type. It likewise comprises expected causes and clinical features such as behaviour during the seizure.
There are more than forty different types of epilepsy comprising: 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, Lafora disease, photosensitive epilepsy and Jacksonian seizure disorder, among others.
Each and every different epilepsy type presents with its own EEG findings, normal age of onset, unique combination of seizure type, own types of treatment and prognosis. 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 generalized epilepsies, localization-related epilepsies and epilepsies of unknown localization.
Localization-related epilepsies are normally known as partial or focal epilepsies. These variations have an epileptic focus, that is a small part of the brain which drives the epileptic response. In contrast, generalized epilepsies occur from many independent foci and are called multifocal epilepsies. These can comprise epileptic circuits that 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 part of the brain.
