13 Possible Causes for Generalized Spike-and-Slow-Waves, Small Hippocampi

  • Generalized Clonic or Tonic-Clonic Seizures

    , 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 pattern.[en.wikipedia.org] Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] According to "Harrisons Manual of Medicine," the EEG during the tonic phase will show a "progressive increase in low-voltage fast wave activity, followed by generalized high-amplitude[en.wikipedia.org]

  • Early Infantile Epileptic Encephalopathy Type 6

    Four children had generalized spike and slow wave or polyspike and slow wave.[neurology.org] During disease progression and increased seizure frequency, however, EEG findings eventually reveal both focal and multifocal anomalies, including generalized spike-and-wave[symptoma.com] […] patient with atypical absence epileptic status, characterized by generalized and irregular slow (2Hz) spike-and-wave complexes.[psiquiatriainfantil.com.br]

  • Tonic-Clonic Seizure

    Initial EEGs showing generalized, unprovoked spikes and waves, generalized paroxysmal discharges precipitated by intermittent photic stimulation, or isolated slowing, were[ncbi.nlm.nih.gov] Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave pattern."[en.wikipedia.org]

  • Temporal Lobe Epilepsy

    Pane, Donatella Lettori, Francesca Chiricozzi, Daniela Chieffo, Tommaso Tartaglione and Charlotte Dravet , Early Thalamic Injury Associated with Epilepsy and Continuous SpikeWave[doi.org] The control of water movement is achieved through a family of small integral membrane channel proteins called aquaporins (AQPs).[ncbi.nlm.nih.gov] By using the left seed, we found two small clusters in both hippocampi (Figure 4C ). The highest t-score was 7.49.[bmcneurosci.biomedcentral.com]

  • Generalized Motor Seizure

    The morphology of the focal spike-and-wave typically appears similar to the generalized spike-and-wave. Ictal.[medlink.com] Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org] , 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 pattern.[en.wikipedia.org]

  • Jacksonian Seizure

    Focal epileptiform discharges occur in secondarily generalized seizures. In absence seizures, spikes and slow waves appear at a rate of 3/sec.[meta-religion.com] Simple partial seizures are seizures which affect only a small region of the brain, often the temporal lobes or structures found there such as the hippocampi.[en.wikipedia.org] […] region of the brain, often the temporal lobes or structures found there such as the hippocampi.[en.wikipedia.org]

  • Myoclonic Jerking

    Ictal EEG : The myoclonic component is associated with a generalized spike or polyspike. The atonic component is associated with the aftergoing high voltage slow wave.[medlink.com] Simple Partial Seizures Simple partial seizures only affect a small part of the brain, usually the temporal lobes or hippocampi, and are usually brief in duration, lasting[efmny.org]

  • Smith Lemli Opitz Syndrome

    EEGs revealed mild generalized slowing with right- and left-side parietal occipital spike-wave discharges.[doi.org] Briefly, the hippocampi or cortices were cut into small pieces, incubated with trypsin at 37 C, and triturated in order to obtain separated cells, which were then plated at[doi.org]
