17 Possible Causes for 3-4 Hz Spikes, Abnormal Spikes, Paroxysmal Activity - Spikes Occipital Right

  • Epilepsy

    (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] […] to 8 years of age, in an otherwise apparently healthy child. 3 The classic electroencephalogram (EEG) shows generalized spike-wave bursts (of 3 Hz) with normal background[doi.org] 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]

  • 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] Childhood absence epilepsy with tonic-clonic seizures and electroencephalogram 3-4-Hz spike and multispike-slow wave complexes: linkage to chromosome 8q24.[reference.medscape.com] EEG shows generalized spike waves and polyspike waves, early photosensitivity, and focal abnormalities.[euroformhealthcare.biz]

  • 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] Interictal electroencephalography (EEG) in JME shows interictal epileptiform discharges such as generalized spikes, polyspikes, bilateral-synchronous 4-6/s spike-wave complexes[go.galegroup.com] […] discharges on electroencephalography, and a lack of focal abnormality on magnetic resonance imaging (MRI).[ncbi.nlm.nih.gov]

  • 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] The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au] Abnormal asymmetry in benign epilepsy with unilateral and bilateral centrotemporal spikes: a combined fMRI and DTI study.[frontiersin.org]

  • Idiopathic Generalized Epilepsy

    The abnormalities included generalized spike-wave and/or spike-polyspike morphology in majority.[annalsofian.org] 4 Hz spikes and waves in all regions of the brain 1 st -line : valproic acid Avoid triggers : sleep deprivation, alcohol, drugs, flickering lights 60% are seizure -free under[amboss.com] Her EEG showed 34 Hz spike and wave discharges. She had a daughter with childhood absence epilepsy, and two sisters and a cousin with seizures (fig 2 , family 1).[jnnp.bmj.com]

  • 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] […] presence of generalized spike- or polyspike-wave EEG discharges at 2-3 Hz, without focal spike discharges; and (4) exclusion of severe and benign myoclonic epilepsy (SME,[ncbi.nlm.nih.gov] 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]

  • 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] Diagnostic methods Diagnosis relies on the clinical features and on electroencephalogram (EEG) recorded awake and during sleep, that displays a generalized 3-4 Hz spike-and-slow-wave[orpha.net] Generalized 3-4 Hz spike or polyspike slow-wave complexes. Neuro Imaging: Not usually required. Mainly from other IGEs such as CAE or Juvenile Myoclonic Epilepsy (JME).[pennsw.com.au]

  • West Syndrome

    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] Abnormality may only be seen in sleep or on wakening.[epilepsydiagnosis.org]

  • 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]
