276 Possible Causes for 3-4 Hz Spikes, Occipital Focal Spikes, Progressive Action Tremor

  • Benign Adult Familial Myoclonic Epilepsy

    Usually, myoclonic tremor is the presenting symptom, characterized by tremulous finger movements and myoclonic jerks of the limbs increased by action and posture.[uniprot.org] .  Previously called early-benign childhood seizures with occipital spikes  Childhood onset (peak 5 years).  Focal autonomic seizures or autonomic status epilepticus, frequently[slideshare.net] 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]

  • Idiopathic Generalized Epilepsy

    The EEG signature of IGE is bisynchronous, symmetric, and generalized spike-wave complex; although focal, irregular, and so called "fragments" of discharges are not uncommon[ncbi.nlm.nih.gov] 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]

  • Juvenile Absence Epilepsy

    Photic stimulation is a recognized cortical precipitant of GSW ( Niedermeyer, 1996 ) and focal occipital spike and slow wave ( Ricci and Vigevano, 1993 ).[academic.oup.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]

  • 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]

    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]
