72 Possible Causes for Abnormal Spikes, Frontal Focal Spikes

  • Epilepsy

    The diagnosis of frontal lobe epilepsy (generalized tonic-clonic seizures secondary to focal impaired awareness seizures and myoclonus) was made.[ncbi.nlm.nih.gov] 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]

  • Benign Adult Familial Myoclonic Epilepsy

    […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[enotes.tripod.com] 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

    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]

  • 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]

  • 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]

  • Juvenile Absence Epilepsy

    Interictal and ictal EEG is characterized by focal generalized spike-wave discharge occasionally prominent in the frontal region.[1pdf.net] 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] Focal discharges were more frequent in the frontal regions 19,25. They may be isolated spikes, sharp waves, slow waves, or spike-and-wave complexes 7,16,21.[scielo.br]

  • Encephalopathy

    *Frontal dominance (FIRDA) --non specific ,diffuse encephalopathy, if focal ?[slideshare.net] Structural abnormalities can often be seen on cranial MRI.[orpha.net] *Repetitive and fairly stereotyped waveforms appearing at regular intervals, sharps/spike waves or complex discharges.[slideshare.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]

  • 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]
