803 Possible Causes for Abnormal Spikes, Mild Cerebellar Hypoplasia, Paroxysmal Activity - Spikes Frontal Bilaterally

  • Benign Adult Familial Myoclonic Epilepsy

    Landau-Kleffner Syndrome and Continuous Spike wave in slow wave sleep: The epileptiform abnormalities seen during sleep EEG in these children is markedly increased compared[epilepsyfoundationmn.org] hypoplasia-hydranencephaly syndrome Multiple acyl-CoA dehydrogenase deficiency Multiple acyl-CoA dehydrogenase deficiency, mild type Multiple acyl-CoA dehydrogenase deficiency[orpha.net] EEG shows generalized spike waves and polyspike waves, early photosensitivity, and focal abnormalities.[euroformhealthcare.biz]

  • West Syndrome

    Brain MRI revealed no abnormal findings although interictal EEG demonstrated left centro-parieto-temporal localized spike foci.[ncbi.nlm.nih.gov] 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] The patient was followed up to 13 years of age, and at the last examination was shown to have severe speech delay, seizures, and continuous spike-and-wave activity on EEG.[ncbi.nlm.nih.gov]

  • Epilepsy

    If you have epilepsy, the EEG may show abnormal spikes or waves in your brain's electrical activity patterns. Different types of epilepsy cause different patterns.[northshore.org] Epileptiform activity characteristic of people with epilepsy includes abnormalities such as spikes, sharp waves and spike-wave complexes, ( slides 21 & 22 ). IV.[ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    We compared the occurrence and involvement of posterior electrodes for focal abnormalities and generalised spike-wave activity in the EEG outside photic stimulation between[ncbi.nlm.nih.gov] […] discharges on electroencephalography, and a lack of focal abnormality on magnetic resonance imaging (MRI).[ncbi.nlm.nih.gov] Neuroimaging typically reveals no abnormalities and EEG frequently reveals generalized spike-wave activity at a frequency of 4-6 hertz.[meddean.luc.edu]

  • Generalized Clonic or Tonic-Clonic Seizures

    Jerk-locked premyoclonus spikes Hand tremor Neuronal loss in central nervous system Cutaneous photosensitivity Hyperreflexia Heterogeneous Weight loss Dystonia Splenomegaly[mendelian.co] Abnormal asymmetry in benign epilepsy with unilateral and bilateral centrotemporal spikes: a combined fMRI and DTI study.[frontiersin.org] EEG abnormalities are more likely or increased with sleep deprivation and during sleep.[epilepsy.com]

  • Idiopathic Generalized Epilepsy

    The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[annalsofian.org] Abstract Magnetic resonance imaging (MRI) techniques have been used to quantitatively assess focal and network abnormalities.[ncbi.nlm.nih.gov] EEG findings About half of patients had an abnormal EEG viz. spikes, polyspikes and slow waves.[annalsofian.org]

  • Myoclonic-Astatic Epilepsy

    The type of abnormal activity is called ‘spike and wave’ or ‘polyspike and wave’. Children with myoclonic-astatic epilepsy are not usually photosensitive.[epilepsy.org.uk] EEG abnormality is enhanced by sleep deprivation and by sleep. Generalized spike-and-wave often becomes fragmented with sleep deprivation or in sleep.[medlink.com] […] and waves, photosensitivity, 4-7/sec rhythms), no multifocal EEG abnormalities (but often pseudofoci).[ncbi.nlm.nih.gov]

  • Juvenile Absence Epilepsy

    Although focal spikes can occur, if they consistently arise in 1 area, consider structural brain abnormality. Caution . If slow spike-and-wave ( Imaging.[medlink.com] The electroencephalogram (EEG) can show focal and generalised abnormalities (sharp waves, spikes or spike and slow waves).[epilepsy.org.uk] However, it should be stressed that asymmetries of the ictal discharge and focal abnormalities of mainly functional spikes are common. 6 8 9 These should not be interpreted[adc.bmj.com]

  • Encephalopathy

    Structural abnormalities can often be seen on cranial MRI.[orpha.net] The characteristic electroencephalogram (EEG) displays a suppression burst pattern (which appears with the onset of spasms) that is comprised of bursts of high amplitude spikes[orpha.net]

  • Uremic Encephalopathy

    Preterminally, the patient becomes immobile and mute. 43 Investigation of dialysis dementia Abnormalities in EEG may precede clinically overt symptoms by up to 6 months.[jnnp.bmj.com] Intermittent bursts of high voltage slowing and spike and wave activity are noted, particularly in the frontal leads. 44 The EEG may show an initial deterioration after treatment[jnnp.bmj.com]
