17 Possible Causes for Abnormal Spikes, Generalized Spike-and-Slow-Waves, Paroxysmal Activity - Spikes Occipital Right

  • Epilepsy

    Electroencephalography (EEG) showed progressively slowed background activity and sporadic generalized spike-and-wave discharges.[ncbi.nlm.nih.gov] (spikes and slow waves); (d) occurrence at any age in childhood and adulthood; (e) frequently demonstrable aetiology (tumor, vascular); and (f) no progressive evolution of[medlink.com] 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]

  • 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] 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] EEG shows generalized spike waves and polyspike waves, early photosensitivity, and focal abnormalities.[euroformhealthcare.biz]

  • Juvenile Myoclonic Epilepsy

    […] multiple spike and spike slow wave discharges (in an untreated patient).8 The possible factors responsible for the delay in the diagnosis of JME were studied retrospectively[neurologyindia.com] 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]

  • 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] 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]

  • Myoclonic-Astatic Epilepsy

    The interictal EEG revealed frequent bursts of generalized 100-200 μV, 2-4 Hz spike-and-slow-wave complexes.[ncbi.nlm.nih.gov] 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]

  • West Syndrome

    Lennox-Gastaut Syndrome: LGS is characterized by multiple types of seizures and an abnormal EEG with generalized slow spikewave discharges.[cdkl5.com] Brain MRI revealed no abnormal findings although interictal EEG demonstrated left centro-parieto-temporal localized spike foci.[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]

  • Idiopathic Generalized Epilepsy

    […] epilepsy K complex lambda mu OIRDA PLEDs phantom spike and wave photic driving photoparoxysmal response photomyogenic artifact poly spike and wave posterior dominant rhythm[eegatlas-online.com] The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[annalsofian.org] The morphology of the focal spike-and-wave typically appears similar to the generalized spike-and-wave. Ictal.[medlink.com]

  • 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] 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]

  • Encephalopathy

    […] delta bursts, that is called as paradoxical arousal response 18. * Background slowing * Increased theta delta activity * Paroxysmal sharp waves * Theta bursts * Delta bursts[slideshare.net] Structural abnormalities can often be seen on cranial MRI.[orpha.net] * Spike discharges *Triphasic waves * FIRDA * OIRDA * TIRDA * Alpha / theta coma Periodic pattern Spindle coma ECS 19.[slideshare.net]

  • Lennox-Gastaut Syndrome

    The semiology of seizures progressively changed to generalized episodes of hypertonia and myoclonus, with slow spike-wave electroencephalographic activity.[ncbi.nlm.nih.gov] All subjects had EEG recordings with generalized epileptiform abnormalities with a spike wave frequency range of 1-5 Hz (median 2 Hz), whereas 8.1% of subjects had EEG studies[ncbi.nlm.nih.gov] […] epilepsy with triad of signs including frequent seizures of multiple types, an abnormal EEG pattern of less than 2.5 Hz slow spike wave activity, and moderate to severe intellectual[wikidata.org]
