16 Possible Causes for lt 25 hz spike and slow waves, Response Is Occipital Spikes in Type 1, Temporal Focal Spikes

Did you mean: lt 25 hz, spike and slow waves, Response Is Occipital Spikes in Type 1, Temporal Focal Spikes

  • Juvenile Absence Epilepsy

    All patients had minimum twice EEG recordings and all had typical 3-Hz generalized spike and slow-wave discharges at least on one EEG.[ncbi.nlm.nih.gov] EEG shows classical generalized 3 Hz spike-and-slow-wave discharges.[medlink.com] Diagnostic methods Diagnosis relies on the clinical features and on electroencephalogram (EEG) recorded awake and during sleep, that displays a generalized 3-4 Hz spike-and-slow-wave[orpha.net]

  • Juvenile Myoclonic Epilepsy

    spikes immediately preceding bisynchronous discharges, and subsequently to temporal intermittent rhythmic delta activity and temporal lobe-onset seizures.[ncbi.nlm.nih.gov] We applied dipole modeling and brain distributed source analysis to find current sources comprising spikes and slow waves of polyspike and wave complexes (PSWC) in patients[ncbi.nlm.nih.gov] Each SWD was divided into six distinct temporal phases: spike onset, spike peak, slow-wave onset, slow-wave ascending, slow-wave peak, and slow-wave descending phases.[ncbi.nlm.nih.gov]

  • Epilepsy

    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] waves.[ncbi.nlm.nih.gov] Cigdem Inan Akman, Nonconvulsive Status Epilepticus and Continuous Spike and Slow Wave of Sleep in Children, Seminars in Pediatric Neurology, 17, 3, (155), (2010).[doi.org]

  • Benign Adult Familial Myoclonic Epilepsy

    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] […] childhood epilepsy with centrotemporal spike -childhood epilepsy with occipital paroxysms Generalized epilepsies & synd.[enotes.tripod.com] In 1824, Calmeil used the term absence . [2] In 1935, Gibbs, Davis, and Lennox described the association of impaired consciousness and 3-Hz spike-and-slow-wave complexes on[reference.medscape.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    […] generalized high-amplitude, poly spike discharges." [2] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave[en.wikipedia.org]

  • West Syndrome

    Brain MRI revealed no abnormal findings although interictal EEG demonstrated left centro-parieto-temporal localized spike foci.[ncbi.nlm.nih.gov] […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[medlink.com] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. B.[bmcneurol.biomedcentral.com]

  • Idiopathic Generalized Epilepsy

    […] and slow waves during clonic phase 70% are seizure -free under treatment In some cases, no medical therapy is necessary avoid triggers Epilepsy with myoclonic-atonic seizures[amboss.com] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[annalsofian.org] […] comorbidities Epilepsy with tonic-clonic seizures alone 14–20 years Tonic-clonic seizures shortly after awakening or during relaxation Fast spikes during tonic phase; bursts of spikes[amboss.com]

  • Encephalopathy

    *Frontal dominance (FIRDA) --non specific ,diffuse encephalopathy, if focal ?[slideshare.net] *Repetitive and fairly stereotyped waveforms appearing at regular intervals, sharps/spike waves or complex discharges.[slideshare.net] […] frontal lobe lesion *OIRDA --occipital dominant ,seen in children as in absence seizure *TIRDA– temporal lobe epilepsy 21.[slideshare.net]

  • 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]

  • Uremic Encephalopathy

    BACKGROUND AND PURPOSE: Uremic encephalopathy is a metabolic disorder in patients with renal failure. The purpose of this study was to describe the MR imaging findings of uremic encephalopathy. MATERIALS AND METHODS: This study retrospectively reviewed MR imaging findings in 10 patients with clinically proved uremic[…][ncbi.nlm.nih.gov]
