1,176 Possible Causes for EEG Slowing, Epileptiform Activity, Hyperreninemia

  • Hyponatremia

    In this setting, release of both antidiuretic hormone (ADH) (increases renal permeability to water) and renin (increases renal sodium retention) occurs.[]

  • Traumatic Brain Injury

  • Epilepsy

    Her EEG showed slow background with continuous occipital small spikes and photosensitivity.[] It remains unclear whether seizures and epileptiform activity on the EEG are causative or comorbid.[] EEG findings showed that slow background activity was significantly common among patients with EP (P 0.009).[]

  • Continuous Spike-and-Slow-Waves during Sleep

    EEG slow wave synchronization during sleep seems to gate interictal epileptiform EEG phenomena.[] Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] EEG of a 16-yr-old child with MR and tonic seizures, showing slow spike wave activity superimposed on a slow BG. 22. EEG of an 11-yr-old pt with LGS showing GPFA. 23.[]

  • Epilepsy with Continuous Spike-and-Slow-Waves during Sleep

    EEG continuous spikes and waves during slow-wave sleep (CSWS), usually 1 to 2 years from seizure onset. Sex Males (62%) show preponderance.[] Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] The EEG in children with this epilepsy syndrome is not normal, especially as they enter sleep. Almost continuous slow-spike-wave is seen during the slow sleep cycle.[]

  • Stroke

    Deep Belief Networks Based Brain Activity Classification Using EEG from Slow Cortical Potentials in Stroke.[] The first EEG background activity asymmetry and first EEG with interictal epileptiform activity were independent predictors of poststroke epilepsy during the first year after[] Abnormal EEG was found in 40 patients (58%) and was associated with higher age (p 0.021). The most common EEG pathology was focal slowing (30; 43.5%).[]

  • Temporal Lobe Epilepsy

    EEG showed focal slow waves and epileptic abnormalities on temporal regions in 1 patient and was normal in the other affected individuals.[] However, little is currently known about the modulation of these networks by epileptiform activity, such as interictal spikes and seizures.[] Focal slowing on EEG was also associated with persistent seizures (p 0.05), although this was correlated with a lesion on MRI.[]

[1] Diagnosis [ edit ] A continuous EEG recording of the brain's electrical activity may help to identify and localize seizure activity, especially in children[] […] of a lesion can be used to determine tumor grade; hypermetabolic lesions often correspond to higher-grade tumors Other studies EEG may be used to evaluate and monitor epileptiform[] However, they are low-grade tumors, with a slow rate of growth, so that patients commonly survive longer than those with otherwise similar types of brain tumour, such as glioblastoma[]

  • Meningoencephalitis

    The diffuse slowing seen on EEG and seizure activity suggest that cerebral cortex was affected by the meningoencephalitis.[] An electroencephalogram was consistent with generalised encephalopathy without focal epileptiform activity.[] There was no evidence of epileptiform activity on electroencephalogram.[]
