229 Possible Causes for Paroxysmal Activity - Spikes, Progressive Action Tremor, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges

  • 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] ) Cortical tremor is a form of rhythmic myoclonus, presenting as postural or action tremor in some patients with progressive myoclonus epilepsy (PME), 76, 77 in Angelman syndrome[clinicalgate.com]

  • 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[ncbi.nlm.nih.gov] ) discharges or generalized spike wave and polyspike wave activity.[brain.oxfordjournals.org] paroxysmal fast activity, diffuse slowing slow background, generalized spike waves MRI normal normal vermis hypoplasia, cisterna magna normal partial agenesis of vermis unknown[ncbi.nlm.nih.gov]

    - or polyspike-wave activity at more than 2.5 Hz without generalized paroxysmal fast activity or focal spikes.[jamanetwork.com] Myoclonic-atonic seizures with falls are the defining symptoms. • EEG shows frequent generalized discharges of spike/polyspike-slow wave at varying frequencies of 2.5 to 3[medlink.com] […] myoclonic, myoclonic-atonic, absence, and generalized tonic-clonic seizures and nonconvulsive status epilepticus. 1 , 2 The electroencephalogram (EEG) shows generalized spike[jamanetwork.com]

  • 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]

  • 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] […] variations between the spike/multispike-slow-wave relationships in generalized discharges of spike-polyspike-slow waves. (3) Predominantly brief discharges (shorter than[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]

  • 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[…][epilepsynw.org]
