In the present study, we used the SISCOM procedure, which represents the fusion of MRI and ictal-interictal difference SPECT images using (99m)Tc-ECD, to study cerebral blood flow changes during the ictal and postictal phases of typical childhood absence [ncbi.nlm.nih.gov]

• Epilepsy

  Abstract Single photon emission computed tomography (SPECT) is currently used in the presurgical evaluation of medically intractable partial epilepsies, but not very often, in generalized epilepsy. [ncbi.nlm.nih.gov]

• Suggestibility

  DISCUSSION: These findings suggest that typical absence seizures involve a network of cortical-subcortical areas necessary for normal attention and primary information processing. [ncbi.nlm.nih.gov]

• Seizure

  In contrast, we observed small early fMRI increases in the orbital/medial frontal and medial/lateral parietal cortex 5 s before seizure onset, followed by profound fMRI decreases continuing 20 s after seizure end. [ncbi.nlm.nih.gov]

• 3-4 Hz Spikes

  Typical absence seizures occur in children, and are accompanied by 3-4-Hz spike-wave discharges (SWDs) on electroencephalography (EEG). [ncbi.nlm.nih.gov]
