481 Possible Causes for Focal Sharp-Waves or Spikes Occipital or Temporal, Generalized Spike-and-Slow-Waves, Mild Cerebellar Hypoplasia

  • Benign Adult Familial Myoclonic Epilepsy

    , high-amplitude spike and slow-wave complexes 3.5 Hz, typically 4 s duration.  Absence seizures in JAE are more sporadic.  EEG is slightly faster with generalized spike[slideshare.net] hypoplasia-hydranencephaly syndrome Multiple acyl-CoA dehydrogenase deficiency Multiple acyl-CoA dehydrogenase deficiency, mild type Multiple acyl-CoA dehydrogenase deficiency[orpha.net] Generalized slow spikes and waves may be present as an interictal pattern, as in Lennox-Gastaut syndrome.[reference.medscape.com]

  • West Syndrome

    Lennox-Gastaut Syndrome: LGS is characterized by multiple types of seizures and an abnormal EEG with generalized slow spikewave discharges.[cdkl5.com] Magnetic resonance imaging of the brain revealed mild cerebral and cerebellar atrophy, high-signal-intensity areas in the white matter, and hypoplasia of the corpus callosum[ncbi.nlm.nih.gov] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. B.[bmcneurol.biomedcentral.com]

  • Epilepsy

    Electroencephalography (EEG) showed progressively slowed background activity and sporadic generalized spike-and-wave discharges.[ncbi.nlm.nih.gov] Neuroimaging studies were unremarkable and electroencephalograms showed high voltage 200-400uV, 2-2.5 Hz generalized spike-and-waves and polyspikes with alternating frontal[ncbi.nlm.nih.gov] […] specified generalized (poly)spike waves, slow spike waves, multifocal discharges, generalized paroxysmal fast activity, diffuse slowing slow background, generalized spike[ncbi.nlm.nih.gov]

  • Generalized Clonic or Tonic-Clonic Seizures

    , poly spike discharges." [2] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave pattern.[en.wikipedia.org] According to "Harrisons Manual of Medicine," the EEG during the tonic phase will show a "progressive increase in low-voltage fast wave activity, followed by generalized high-amplitude[en.wikipedia.org]

  • Juvenile Absence Epilepsy

    All patients had minimum twice EEG recordings and all had typical 3-Hz generalized spike and slow-wave discharges at least on one EEG.[ncbi.nlm.nih.gov] EEG shows classical generalized 3 Hz spike-and-slow-wave discharges.[medlink.com] The EEG has generalized spike or polyspike slow-wave complexes. JAE is a lifelong disorder, although seizures can be controlled in 70% to 80% of patients.[pennsw.com.au]

  • Organic Brain Syndrome

    Abstract This study addresses the prevalence of organic brain syndrome (OBS) among long-term toluene-exposed rotagravure workers who are still working. The prevalence of OBS in 22 workers exposed to toluene for a minimum of 12 years and 19 unexposed control subjects, matched for age and employment status,[…][ncbi.nlm.nih.gov]
