Postictal mixed transcortical aphasia
Postictal aphasia has been described in left temporal lobe seizures. It may be of fluent, non-fluent or global type. We present here a patient who displayed signs of mixed transcortical aphasia (MTCA). The patient was a 67 year old man who underwent excision of a left frontal parasagittal meningioma in 1987. Since then he has been treated with phenytoin for generalized tonic-clonic seizures (GT...
متن کاملPeri-ictal and interictal, intracranial infraslow activity.
It is widely assumed that the recording of EEG infraslow activity (ISA) requires direct current amplifiers. Yet, it has been shown during the past decade that conventional EEG systems can record activity between 0.01 and 0.1 Hz and that this frequency band contains additional information, especially in regard to seizure onset. To delineate the characteristics of background ISA, 24-hour scalp an...
متن کاملCerebral artery air embolism following an esophagogastroscopy: a case report.
believe it is important to consider the possibility that prolonged “postictal” deficits may be due to ongoing ictal discharges, as additional anticonvulsant medication may be indicated. There were rare periods in this case when there were subtle pseudoperiodic discharges on the scalp EEG during ongoing ictal activity intracranially, and persistent aphasia. This supports the view that in some in...
متن کاملProlonged Ictal Aphasia Presenting as Clinical-Diffusion Mismatch in a Patient with Acute Ischemic Stroke
permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. The presence of clinical-diffusion mismatch (CDM) in patients with acute ischemic stroke may represent the ischemic penumbra, which requires emergency reperfusion therapy to improve stroke outcomes. We report here our experience of treating a patient with acute is...
متن کاملPostictal aphasia with transient sulcal hyperintensity on MRI.
A 38-year-old man had postictal global aphasia after generalized tonic-clonic seizure, but recovered within 1 day. There was a focal increase in the signal intensity of the left frontoparietal sulci on fluid-attenuated inversion recovery magnetic resonance (MR) sequence 6 hours after the seizure, which disappeared 1 month later. The transient seizure-induced MR hyperintensity was possibly cause...
