Insights

Aphasic status epilepticus can cause diffusion-weighted imaging (DWI) abnormalities. Cortical DWI hyperintensities may appear shortly after aphasic status epilepticus, as seen in this patient.

Area of Science:

  • Neurology
  • Neuroradiology

Background:

  • Partial status epilepticus typically presents with focal neurological deficits.
  • Global aphasia as the primary symptom of partial status epilepticus is rare.
  • Diffusion-weighted imaging (DWI) abnormalities are common after prolonged seizures.

Purpose of the Study:

  • To report magnetic resonance imaging (MRI) findings in a patient with aphasic status epilepticus.
  • To summarize brain imaging findings in status epilepticus.
  • To discuss the mechanism of DWI abnormalities in this context.

Main Methods:

  • Case report of a patient with aphasic status epilepticus.
  • Review of literature on brain imaging in status epilepticus.
  • Analysis of MRI findings, including DWI and diffusion restriction.

Main Results:

  • The patient's MRI revealed diffusion restriction four hours after symptom onset.
  • Cortical DWI hyperintensities were observed in this case.
  • Literature review confirmed that DWI abnormalities can occur in status epilepticus.

Conclusions:

  • Aphasic status epilepticus can manifest with early cortical DWI hyperintensities.
  • These findings suggest a potential mechanism for diffusion restriction in the brain during epileptic seizures.

Seizures l: Introduction

Understanding seizures and epilepsy relies on key definitions that help in recognizing, classifying, and managing these disorders. These definitions provide a framework for recognizing, classifying, and managing seizure disorders.DefinitionsA seizure is a sudden, abnormal burst of electrical activity in the brain that can cause changes in awareness, movement, sensation, or behavior, depending on the area involved. Epilepsy is a chronic condition characterized by recurrent, unprovoked seizures,...

Transient Ischemic Attack l: Introduction

A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
