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 ...
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. More specifically, a functional MRI, or fMRI, can detect changes in blood flow throughout the brain when specific parts of the brain are being used ...
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.
In newly diagnosed epilepsy, magnetic resonance imaging (MRI) can detect brain lesion in up to 12 to 14% of persons with epilepsy. [31] However, for those with chronic epilepsy, MRI can detect brain lesion in 80% of the persons with epilepsy. [31] 3-Tesla MRI scan is advised for those with evidence of focal epilepsy such as temporal lobe ...
Furthermore, MRI can diagnose whether ulegyria presence is unilateral or bilateral. [1] Electroencephalography, EEG, can also be used to screen for ulegyria, though MRI is still preferred. This is mainly done for epilepsy patients as abnormalities in EEG recordings indicate the presence of ulegyria in the area of the brain being tested. [7]
Ohtahara syndrome (OS), also known as Early Infantile Developmental & Epileptic Encephalopathy (EIDEE) [2] is a progressive epileptic encephalopathy.The syndrome is outwardly characterized by tonic spasms and partial seizures within the first few months of life, [3] and receives its more elaborate name from the pattern of burst activity on an electroencephalogram (EEG).
