689 Possible Causes for Epileptiform Activity, Hyperreninemia, Occipital Slowing

  • Traumatic Brain Injury

    Ling, Spontaneous Epileptiform Activity in Rat Neocortex after Controlled Cortical Impact Injury, Journal of Neurotrauma, 27, 8, (1541), (2010).[] Kombian, Anticonvulsant enaminone E139 suppresses epileptiform activity in rat hippocampal slices, Epilepsy Research, 76, 2-3, (85), (2007).

Neese, Luke K.[] Tevfik Yılmaz, Metehan Akça, Yahya Turan, Hakan Ocak, Kağan Kamaşak and Mehmet Yildirim, Efficacy of dexamethasone on penicillin-induced epileptiform activity in rats: An[]

  • Epilepsy

    It remains unclear whether seizures and epileptiform activity on the EEG are causative or comorbid.[] Her EEG showed slow background with continuous occipital small spikes and photosensitivity.[] Through an accurate Video-EEG polygraphic analysis, we demonstrated that seizures are related to an abnormal increase of epileptiform activity after eye-closure or loss of[]

  • Hyponatremia

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

  • 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[] Key words: abnormal EEG, non-epileptiform abnormalities, slow activity.[] Periodic Lateralized Epileptiform Discharges (PLEDs) are EEG abnormalities that signify acute brain dysfunction or unilateral brain lesion, usually destructive in nature,[]

  • Temporal Lobe Epilepsy

    However, little is currently known about the modulation of these networks by epileptiform activity, such as interictal spikes and seizures.[] Other medical conditions with similar symptoms include panic attacks, psychosis spectrum disorders, tardive dyskinesia, and occipital lobe epilepsy.[] Characterized by a benign behaviour, a slow growth, a sharp delineation and usually show absence of edema.[]

  • Meningoencephalitis

    An electroencephalogram was consistent with generalised encephalopathy without focal epileptiform activity.[] There was no evidence of epileptiform activity on electroencephalogram.[] A noncontrast computed tomographic scan of the head was normal, and an electroencephalogram (EEG) showed diffuse slowing but no epileptiform activity.[]

  • Encephalitis

    Some peculiar patterns in this activity can be related to the diagnosis of encephalitis, for e.g. in HSE, EEG often documents characteristic paroxysmal lateral epileptiform[] The presence of periodic lateralized epileptiform discharges (PLEDs) is associated with HSV encephalitis but may also be consistent with seizure activity, EBV encephalitis[] Electroencephalogram (EEG) can be done to record the electrical activity of the brain.[]

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

    Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] The waking interictal EEG showed a slow left temporo-occipital focus (Fig. 3A).[] The discharge is often slightly faster than 3 Hz at onset, and tends to slow down towards the end.[]

  • Continuous Spike-and-Slow-Waves during Sleep

    Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] Slowing of PDR, ND, intermittent rhythmic delta in frontal / occipital, sometimes triphasic, occipital spikes, focal slowing (this is not s/f lesion). Intox DND.[] epileptiform activity on the patient are unclear.[]
