Brain mapping by the technique of cortical electrical stimulation or electrocorticography are other procedures used in the process of invasive testing for certain patients. [19] Once the epilepsy focus is located, the specific surgery involved in treatment is decided on. The type of surgery depends on the location of the seizure focal point.
Dysembryoplastic neuroepithelial tumour (DNT, DNET) is a type of brain tumor.Most commonly found in the temporal lobe, DNTs have been classified as benign tumours. [1] These are glioneuronal tumours comprising both glial and neuron cells and often have ties to focal cortical dysplasia.
Focal cortical dysplasia is a brain malformation that may cause temporal lobe epilepsy. [27] This malformation may cause abnormal cortical layers ( dyslamination ), occur with abnormal neurons ( dysmorphic neurons, balloon cells ) and may occur with a brain tumor or vascular malformation. [ 27 ]
Focal means that it is limited to a focal zone in any lobe. [2] Focal cortical dysplasia is a common cause of intractable epilepsy in children and is a frequent cause of epilepsy in adults. There are three types of FCD with subtypes, including type 1a, 1b, 1c, 2a, 2b, 3a, 3b, 3c, and 3d, each with distinct histopathological features.
Amygdalohippocampectomy is a surgical procedure for the treatment of epilepsy.It consists of the removal of the hippocampus, which has a role in memory, spatial awareness, and navigation, [1] and the amygdalae, which have a role in the processing and memory of emotional reactions, [2] both structures forming part of the limbic system of the brain.
Quality of life questionnaires and other assessment tools have been created to help quantify quality of life for individual patients. They consider such factors as physical health (including numbers and severity of seizures, medication side effects etc.), mental health, social relationships, lifestyle, role activities and life fulfillment. [16]
Multiple subpial transections is a surgical treatment modality for epilepsy used in scenarios wherein epileptogenic brain regions (from where partial seizures originate) cannot be removed safely. The surgeon makes a series of shallow cuts (transections) into the brain's cerebral cortex. These cuts are thought to interrupt some fibers that ...
The effects of epilepsy on language may be impacted by location of epileptiform activity, severity and duration of electrical discharges, age of onset, treatment method, and surgical resection areas. In some cases, language impairment may be the first indicator of epileptiform activity in the brain of children.
