17 Possible Causes for Paroxysmal Activity - Spikes, Paroxysmal Activity - Spikes Central Bilaterally, Paroxysmal Activity - Spikes Temporal Bilaterally

  • Benign Adult Familial Myoclonic Epilepsy

    Alvarez and Lombroso reported hypnagogic paroxysmal spike wave activity (minimal epileptiform features, sharp waves embedded into hyperventilation, or hypnagogic hypersynchrony[] Between these bursts are inserted periods of variable duration without obvious paroxysmal discharges but with θ–wave activity of variable amplitude involving both central[] Since altered awareness occurs with even brief bursts of spike-wave paroxysms on EEG, treatment should be titrated to suppressing all epileptiform activity.[]

  • Epilepsy

    At 9 years, video EEG monitoring showed a striking pattern of interictal slow spike-wave and paroxysmal fast activity, maximal over the right, initially unaffected, hemisphere[] […] and a focal paroxysmal abnormality (spikes and slow waves); (d) occurrence at any age in childhood and adulthood; (e) frequently demonstrable aetiology (tumor, vascular);[] paroxysmal fast activity, diffuse slowing slow background, generalized spike waves MRI normal normal vermis hypoplasia, cisterna magna normal partial agenesis of vermis unknown[]

  • 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[]

  • Myoclonic-Astatic Epilepsy

    - or polyspike-wave activity at more than 2.5 Hz without generalized paroxysmal fast activity or focal spikes.[] […] including myoclonic, myoclonic-atonic, absence, and generalized tonic-clonic seizures and nonconvulsive status epilepticus. 1, 2 The electroencephalogram (EEG) shows generalized spike[]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][]

  • Juvenile Myoclonic Epilepsy

    History Juvenile myoclonic epilepsy (JME) is diagnosed on the basis of clinical findings. Video-electroencephalography (EEG) monitoring of typical seizures is the criterion standard, but in the great majority of patients, a working diagnosis of probable JME is made on the basis of the clinical history, often with[…][]

  • West Syndrome

    IARS2 encodes isoleucine-tRNA synthetase, which is aclass-1 amino acyl-tRNA synthetase. IARS2 mutations are reported to cause Leigh syndrome or cataracts, growth hormone deficiency, sensory neuropathy, sensorineural hearing loss, and skeletal dysphasia syndrome (CAGSSS). To our knowledge, IARS2 mutations and[…][]

  • Encephalopathy

    […] and paroxysmal bursts of sharp and slow waves, these drugs increase epileptiform activity in known epileptic patients, clozapine increase bilateral spike waves discharges[] […] delta bursts, that is called as paradoxical arousal response 18. * Background slowing * Increased theta delta activity * Paroxysmal sharp waves * Theta bursts * Delta bursts[] * Spike discharges *Triphasic waves * FIRDA * OIRDA * TIRDA * Alpha / theta coma Periodic pattern Spindle coma ECS 19.[]

  • Juvenile Absence Epilepsy

    The discharge is heterogeneous, often asymmetrical and may include irregular spike and slow wave complexes, fast and other paroxysmal activity.[] Since altered awareness occurs with even brief bursts of spike-wave paroxysms on EEG, treatment should be titrated to suppressing all epileptiform activity.[] Ictal - EEG is of slow (less than 2.5 Hz) spike and slow wave.[]

  • Uremic Encephalopathy

    […] discharges (PLEDS). [37] In hypokalemia, diffuse slow activity can be seen together with paroxysmal delta/theta activity, as well as focal paroxysms of sharp waves and spike-waves[] ., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions. [37] In hyponatremia, EEG detects[] […] diffuse slowing in the theta range, followed by paroxysmal delta activity and FIRDA or periodic delta waves, as well as the occurrence of periodic lateralized epileptiform[]
