  • Benign Adult Familial Myoclonic Epilepsy

    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] T2 weighted brain MRI shows an ”eye of the tigersign corresponding to pallidal hypointensity with a high signal center.[neuroweb.us] […] wave in burst or isolation  Photic stimulation 40%  Theta rhythm of 5-6Hz in central and vertex 95% 43. 17 m. child with SW induced by opening and closing eyelids Recurrence[slideshare.net]

  • 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]

  • Unverricht-Lundborg Syndrome

    There are generalized polyspike discharges at rest that are exacerbated by photic stimulation.

  • 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]

  • Epilepsy

    Focal cortical dysplasia is a common cause of medically refractory epilepsy in infancy and childhood. We report a neonate with seizures occurring within the first day of life. Continuous video-EEG monitoring led to detection of left motor seizures and a right frontal EEG seizure pattern. Brain MRI revealed a lesion[…][ncbi.nlm.nih.gov]

  • Idiopathic Generalized Epilepsy

    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

    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] EEG: Usually normal background particularly at onset of syndrome, with frequent generalised discharges of 2 to 3 Hz spike/polyspike wave.[pennsw.com.au]
