227 Possible Causes for Jerk-Locked Premyoclonus 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] […] cortical spikes detected by the jerk-locked back-averaging) ( Ikeda et al., 1990 ).[academic.oup.com]

  • Generalized Clonic or Tonic-Clonic Seizures

  • Epilepsia Partialis Continua

    ) Cortical tremor is a form of rhythmic myoclonus, presenting as postural or action tremor in some patients with progressive myoclonus epilepsy (PME), 76, 77 in Angelman syndrome[clinicalgate.com] Structural MRI showed a region of focal cortical dysplasia (FCD) over the right central gyrus and lesions in the mesial frontal and occipital cortex secondary to perinatal[ncbi.nlm.nih.gov] Jerk-locked back averaging (JLA) of magnetoencephalogram disclosed a spike preceding the jerk localized at the hand motor area, whereas JLA of electroencephalogram revealed[ncbi.nlm.nih.gov]

  • 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] Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov]

  • 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] Previous clinical and EEG studies show a relationship between generalized and focal spike–wave discharges in some situations.[academic.oup.com] Furthermore, the electrographic findings in both syndromes include GSW or occipital spikes. This overlap may be due to shared genetic determinants.[academic.oup.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]
