• Multifocal Spikes

  The classic interictal EEG finding is the hypsarrhythmia pattern, which consists of a highvoltage, disorganized background with multifocal spike and sharp waves. [euroformhealthcare.biz]

  Cortical myoclonus is more commonly encountered in a multifocal form, presenting with multifocal spike discharges. If myoclonus is triggered by stimuli, the term cortical reflex myoclonus is used. [neupsykey.com]

The most important indicator of prognosis is tumor stage. [mycancergenome.org]

Although there are advances in therapy and research in Doose Syndrome, prognosis and outcome tends to be unpredictable and varied. Prognosis is more likely to be unfavourable in children who have generalised tonic clonic seizures from the outset. [epilepsyqueensland.com.au]

The prognosis is worse if the spasms are either symptomatic or cryptogenic. [euroformhealthcare.biz]

We conclude that the etiology of BAFME remains to be solved, and further genetic studies, which may require analysis in non-coding regions of a gene, introns or intergenic spacer regions, are necessary to reveal its unknown mutations. [ncbi.nlm.nih.gov]
