The EEG finding in CAE is generalized 3 Hz spike and wave discharges. Some go on to develop generalized tonic-clonic seizures. This condition carries a good prognosis because children do not usually show cognitive decline or neurological deficits, and the seizures in the majority cease spontaneously with ongoing maturation.

Dysembryoplastic neuroepithelial tumour, MRI FLAIR. A dysembryoplastic neuroepithelial tumour is commonly diagnosed in patients who are experiencing seizures with magnetic resonance imaging (MRI), electroencephalogram (EEG). [4] A DNT is most commonly diagnosed in children who are experiencing seizures, and when given medication do not respond ...
EEG used to be a first-line method of diagnosis for tumors, stroke, and other focal brain disorders, [4] [5] but this use has decreased with the advent of high-resolution anatomical imaging techniques such as magnetic resonance imaging (MRI) and computed tomography (CT). Despite its limited spatial resolution, EEG continues to be a valuable ...
Ictal EEG's show occipital paroxysmal fast activity, spiking, or both, as well as brief occipital flattening. About one-third of occipital seizures do not show any obvious changes. [5] An MRI would be performed to look at any lesions, damage, or abnormalities in the occipital region of a patient's brain.
An EEG is a procedure that records the brain's electrical activity. This is done by attaching electrodes to the scalp. This test is done to see how medicine is affecting the electrical problems in the brain. Medication may not be required to be taken indefinitely. Children may be taken off medicine if no seizures are experienced for 1 to 2 years.
Structural magnetic resonance imaging (structural MRI) of a head, from top to base of the skull. The first chapter of the history of neuroimaging traces back to the Italian neuroscientist Angelo Mosso who invented the 'human circulation balance', which could non-invasively measure the redistribution of blood during emotional and intellectual activity.
Given the nocturnal activity, a sleep EEG can often be helpful. Technically, the label "benign" can only be confirmed if the child's development continues to be normal during follow-up. [4] Neuroimaging, usually with an MRI scan, is only advised for cases with atypical presentation or atypical findings on clinical examination or EEG.
Both magnetic resonance imaging (MRI) and computer tomography (CT) scans generally appear normal in JME patients. However a number of quantitative MRI studies have reported focal or regional abnormalities of the subcortical and cortical grey matter, particularly the thalamus and frontal cortex, in JME patients.
