310 Possible Causes for Paroxysmal Activity - Spikes, Progressive Action Tremor, Temporal Focal Spikes

  • 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] EEG during drowsiness and sleep showing frequent bilateral synchronous/independent biphasic spikes followed by slow waves in the centro-temporal regions. 32.  Childhood/adolescent[slideshare.net]

  • 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] In infancy, the EEG background was normal (1), showed diffuse (3) or focal slowing that was temporal (1) and in the left hemisphere (1), and showed focal (central, temporal[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]

    spikes immediately preceding bisynchronous discharges, and subsequently to temporal intermittent rhythmic delta activity and temporal lobe-onset seizures.[ncbi.nlm.nih.gov] In this rare case of coexistent primary generalised epilepsy and focal epilepsy, the epileptic networks of the two forms of epilepsy appear to overlap.[ncbi.nlm.nih.gov] […] was an electrographic evolution from the typical generalised epileptiform patterns, characteristic of juvenile myoclonic epilepsy, to the novel appearance of interictal temporal[ncbi.nlm.nih.gov]

  • West Syndrome

    Brain MRI revealed no abnormal findings although interictal EEG demonstrated left centro-parieto-temporal localized spike foci.[ncbi.nlm.nih.gov] The focal ES of one lower limb, following treatment of ES in these two infants with WS, suggests the origin of the ES in the first case to be a neocortical focus involving[ncbi.nlm.nih.gov]

  • 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]

  • 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]

  • 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] 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] Ictal - EEG is of slow (less than 2.5 Hz) spike and slow wave.[en.wikipedia.org]

[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[neurologyindia.com] ., frontal intermittent rhythmic delta activity (FIRDA), or spikes and sharp waves as well as spike-wave discharges in temporal regions.

  • Organic Brain Syndrome

    Abstract This study addresses the prevalence of organic brain syndrome (OBS) among long-term toluene-exposed rotagravure workers who are still working. The prevalence of OBS in 22 workers exposed to toluene for a minimum of 12 years and 19 unexposed control subjects, matched for age and employment status,[…][ncbi.nlm.nih.gov]
