221 Possible Causes for Paroxysmal Activity - Spikes, Polyspike on Photic Stimulation, 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] This was referred to as posterior paroxysmal activity by Holmes et al.[euroformhealthcare.biz] Photic stimulation and hyperventilation were performed in all. RESULTS: Nineteen (eight men, 11 women) patients with BAFME were included in this study.[ncbi.nlm.nih.gov]

  • Unverricht-Lundborg Syndrome

    AMRF typically presents at ages 15 to 25 years either with neurologic symptoms (including tremor, action myoclonus, seizures, and ataxia) or with proteinuria that progresses[ncbi.nlm.nih.gov] There are generalized polyspike discharges at rest that are exacerbated by photic stimulation. Fig. 2 EEG of individual V-13 at age 35 years.[academic.oup.com] .  EEG - diffuse slow background activity and generalised high-voltage spike and wave, and polyspike and wave paroxysms, ranging from 2–3 Hz to 4–6 Hz, which reach a maximum[slideshare.net]

  • Epilepsy

  • Idiopathic Generalized Epilepsy

    Generalized spike-wave discharges and diffuse paroxysmal fast activity were categorized as interictal and ictal, based on duration of less than 10 seconds or greater, respectively[ncbi.nlm.nih.gov] These discharges are often precipitated by hyperventilation, sleep deprivation, and intermittent photic stimulation (IPS).[epilepsy.com] EEG shows generalized discharges of spikes, polyspikes, or spike/polyspike-waves either ictally or inter-ictally.[epilepsy.com]

  • Myoclonic-Astatic Epilepsy

    - or polyspike-wave activity at more than 2.5 Hz without generalized paroxysmal fast activity or focal spikes.[jamanetwork.com] Photic stimulation may trigger generalised spike/wave or myoclonic astatic seizures.[pennsw.com.au] Intermittent photic stimulation may trigger generalized spike-and-wave and polyspike-and-wave, and myoclonic-atonic seizures.[medlink.com]

  • Juvenile Myoclonic Epilepsy

    Two cases of juvenile myoclonic epilepsy (JME) presented with myoclonic jerks and EEG activation after eye closure, without sensitivity to intermittent photic stimulation.[ncbi.nlm.nih.gov] These discharges may be evoked by photic stimulation (blinking lights) and/or hyperventilation.[en.wikipedia.org] These changes are often induced by photic stimulation (blinking lights) and sometimes hyperventilation.[medindia.net]

  • Generalized Clonic or Tonic-Clonic Seizures

    Specific EEG changes may be seen during photic stimulation. EEG abnormalities are more likely or increased with sleep deprivation and during sleep.[epilepsy.com] Other information is obtained from tests such as: EEG (electroencephalogram) : people with EGTCS have normal EEG background and generalized spike wave or polyspike wave activity[epilepsy.com]

  • Juvenile Absence Epilepsy

    The discharge is heterogeneous, often asymmetrical and may include irregular spike and slow wave complexes, fast and other paroxysmal activity.[en.wikipedia.org] However, on EEG, intermittent photic stimulation often facilitates generalized discharges and absences.[medlink.com] Since altered awareness occurs with even brief bursts of spike-wave paroxysms on EEG, treatment should be titrated to suppressing all epileptiform activity.[reference.medscape.com]
