The amount of brain removed during the surgery depends on the extent of the brain involved in the seizures. It can range from just removing one lobe of the brain (temporal lobectomy) to disconnecting an entire side of the brain (hemispherectomy). [5] The procedure can be curative, where seizures are eliminated completely. [5]
Epilepsy. A convulsion is a medical condition where the body muscles contract and relax rapidly and repeatedly, resulting in uncontrolled shaking. [1] Because epileptic seizures typically include convulsions, the term convulsion is often used as a synonym for seizure. [1] However, not all epileptic seizures result in convulsions, and not all ...
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1] The occurrence of two or more unprovoked seizures defines epilepsy. [11]
Epilepsy is a neurological condition of recurrent episodes of unprovoked epileptic seizures. A seizure is an abnormal neuronal brain activity that can cause intellectual, emotional, and social consequences. Epilepsy affects children and adults of all ages and races, and is one of the most common neurological disorders of the nervous system. [1]
Temporal lobe in green. In the field of neurology, temporal lobe epilepsy is an enduring brain disorder that causes unprovoked seizures from the temporal lobe. Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. [1] Seizure symptoms and behavior distinguish seizures arising from the medial temporal lobe from ...
Epileptogenesis. Epileptogenesis is the gradual process by which a typical brain develops epilepsy. [1] Epilepsy is a chronic condition in which seizures occur. [2] These changes to the brain occasionally cause neurons to fire in an abnormal, hypersynchronous manner, known as a seizure. [3]
The neurovascular unit (NVU) comprises the components of the brain that collectively regulate cerebral blood flow in order to deliver the requisite nutrients to activated neurons. [1] The NVU addresses the brain's unique dilemma of having high energy demands yet low energy storage capacity. In order to function properly, the brain must receive ...
A brain injury can cause seizure(s) because of the unusual amount of energy that is discharged across of the brain when the injury occurs and thereafter. A disruption of the supply of oxygen may cause damage to the temporal lobe of the brain. [35] The risk of seizure(s) from a closed head injury is about 15%. [36]
