17 Possible Causes for 3-4 Hz Spikes, Paroxysmal Activity - Spikes Central Bilaterally, Paroxysmal Activity - Spikes Temporal Bilaterally

  • Benign Adult Familial Myoclonic Epilepsy

    Between these bursts are inserted periods of variable duration without obvious paroxysmal discharges but with θ–wave activity of variable amplitude involving both central[neupsykey.com] 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] 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]

  • Epilepsy

    […] 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] Hz Spike and Wave Discharges, Epilepsia, 31, 5, (557-566), (2007).[doi.org] […] childhood-onset epilepsy, making it the most common form of pediatric epilepsy. 1,2 The syndrome is characterized by daily frequent but brief staring spells, typically beginning at 4[doi.org]

  • Generalized Clonic or Tonic-Clonic Seizures

    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]

  • Juvenile Myoclonic Epilepsy

    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] Myoclonic jerks appear to be time-locked to generalized 3-5 Hz spike-and wave complexes [8]. Photoparoxysmal response was seen in 40% of patients.[go.galegroup.com]

  • Idiopathic Generalized Epilepsy

    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] The EEG usually shows asymptomatic 3 to 4 Hz generalized spike/polyspike discharges, but often video-EEG after partial sleep deprivation with recording in sleep and awakening[medlink.com]

  • Myoclonic-Astatic Epilepsy

    […] 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 shows regular and irregular bilaterally synchronous 2- to 3-Hz spike-waves and polyspike patterns with a 4- to 7-Hz background. 84% of affected children show normal development[ipfs.io] […] before onset of epilepsy and absence of organic cerebral abnormalities; (2) onset of myoclonic, myoclonic-astatic or astatic seizures between 7 months and 6 years of age; (3)[ncbi.nlm.nih.gov]

  • Juvenile Absence Epilepsy

    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] Childhood absence epilepsy with tonicclonic seizures and electroencephalogram 3-4-Hz spike and multispikeslow wave complexes: linkage to chromosome 8q24.[books.google.es]

  • West Syndrome

    IARS2 encodes isoleucine-tRNA synthetase, which is aclass-1 amino acyl-tRNA synthetase. IARS2 mutations are reported to cause Leigh syndrome or cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, and skeletal dysphasia syndrome (CAGSSS). To our knowledge, IARS2 mutations and[…][ncbi.nlm.nih.gov]

  • 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]

  • Encephalopathy

    Posterior reversible encephalopathy syndrome is an encephalopathy that can be clinically characterized by headache, altered mental status and/or seizures. Neuroimaging demonstrates usually reversible bilateral subcortical vasogenic occipital-parietal edema. Exact pathophysiology remains unclear but is commonly[…][ncbi.nlm.nih.gov]
