What is the Epileptogenic area?
The epileptogenic zone is defined as the region of the brain from which the patient’s habitual seizures arise.
What does Epileptogenic potential mean?
According to the new terminology, epileptogenesis refers to the development and extension of tissue capable of generating SRSs, resulting in (1) development of an epileptic condition, and/or (2) progression of the epilepsy after it is established.
What is focal Epileptogenic focus?
Focal epilepsy is a condition in which a localized area of the brain produces spontaneous and recurrent seizures (Fisher et al., 2014). Underlying this condition is a process called epileptogenesis, which results in a seemingly normal brain becoming epileptic (Pitkanen et al., 2014).
What causes epileptogenesis?
Anything that causes epilepsy causes epileptogenesis, because epileptogenesis is the process of developing epilepsy.
What do XL spikes mean on EEG?
Spikes or sharp waves are terms commonly seen in EEG reports. If these happen only once in a while or at certain times of day, they may not mean anything. If they happen frequently or are found in specific areas of the brain, it could mean there is potentially an area of seizure activity nearby.
Can an EEG tell if you have a tumor?
An EEG is done to: detect and locate abnormal electrical activity in the brain. identify the location of a suspected brain tumour, inflammation, infection, bleeding or head injury. diagnose and monitor diseases such as epilepsy (a seizure disorder), narcolepsy (a sleep disorder) and swelling of the brain.
What are 3 common seizure types?
Tonic, Clonic and Tonic-Clonic (Formerly called Grand Mal) Seizures.
What is epileptogenesis?
Epileptogenesis may be defined as the development of recurrent unprovoked seizures. The brain of the neonate or the infant is very seizure-prone, but many seizures are transient (Hauser, 1995).
What is the epileptogenic zone?
The Epileptogenic Zone: 1990s–early 2000s – Subdural Electrodes (SDE) Theoretical Definition In 1993, Luders et al. defined the EZ as “the area of cortex that is necessary and sufficient for initiating seizures and whose removal (or disconnection) is necessary for complete abolition of seizures” (8). Surgical Definition
Can magnetic resonance imaging help define the epileptogenic zone of epilepsy?
Functional magnetic resonance imaging networks induced by intracranial stimulation may help defining the epileptogenic zone. 2014; 4: 286– 298. [PMC free article][PubMed] [Google Scholar]
Is epileptogenesis related to the plasticity of neurons?
Epileptogenesis and plasticity of neuronal networks are two related phenomena because some epileptogenic lesions show clear reorganization of neuronal connections and growth of neuronal elements. This is conspicuous in epileptogenic foci induced by kindling, but even more so in ‘poststatus epilepticus’ (SE) experimental models of chronic epilepsy.
