Magnetic Resonance Imaging (MRI) scan An MRI scan looks at the structure of the brain and may help to find the cause of your epilepsy. Your doctor may order several tests to diagnose epilepsy and determine the cause of seizures. Clinicians can find evidence of abnormal electrical activity in the brain and figure out the type or types of seizures a patient is having, as well as the origin(s), by measuring brain waves over minutes to a couple of hours. Improved lesion detection requires both a dedicated epilepsy protocol for MRI optimized for lesion detection and the interpreting radiologist's familiarity with common causes of epilepsy. Patients with temporal lobe epilepsy demonstrate three phases, each of variable duration and symptomatology: 1. preictal (aura) phase 2. ictal phase 3. postictal phase A variable number of patients with temporal lobe epilepsy demonstrate or describe an aura, which is usually of short duration, and in most cases (70%) goes on to become a seizure 2.

It can show up abnormalities of the shape or structure of the brain which could give rise to epileptic seizures. In patients with newly diagnosed epilepsy, MRI may identify an epileptogenic lesion in 12–14%, but up to 80% of the patients with recurrent seizures have structural abnormalities evident on MRI.

This may be small changes in how the brain tissue developed, blood vessel changes, or changes as a result of a tumour or traumatic brain injury. It does not show seizure activity in itself. In fact, since the EEG records only a 30-minute snapshot of the brain’s activity, many EEGs are normal. An MRI shows areas of blood flow in the brain and may help caregivers plan epilepsy surgery, if it is needed. If the seizure is due to a mass in the brain, ct may see it, but MRI is better. Top answers from doctors based on your search: Disclaimer.

Sometimes your seizures do not show up on an EEG but, that does not mean you do not have a problem. T1WI Superior for cortical thickness and the interface between grey and white matter. The neurologist looks for spikes or sharp waves ("epilepsy waves") to confirm the diagnosis, but the absence of these abnormal brain waves does not mean you didn't have a seizure in the past. It is also possible for a person to have an ‘abnormal’ CT or MRI and not have a diagnosis of epilepsy. This involves 24 hour video recording of a patient in a testing facility with electrodes recording brain activity both awake and while sleeping and eating. To determine the endophenotypic potential of structural MRI in juvenile myoclonic epilepsy (JME), we examined MRI-based cortical morphologic markers in patients and their healthy siblings. 1 Surgery is a therapeutic option for patients with drug-resistant focal epilepsy.
