Transient amnesia episodes preceded persistent memory loss and left thalamus infarction in a patient. Thalamic ischemia may cause transient global amnesia.

Area of Science:

  • Neurology
  • Neuroimaging
  • Neuropsychology

Background:

  • Transient global amnesia (TGA) is a distinct syndrome characterized by sudden, temporary memory loss.
  • The underlying pathophysiology of TGA remains incompletely understood, with various hypotheses proposed.

Observation:

  • A patient experienced two episodes of transient amnesia with similar neurobehavioral symptoms.
  • Following these episodes, the patient developed persistent amnesia and was diagnosed with an acute infarction in the left thalamus.

Findings:

  • Cranial computed tomography scans were normal after the initial two transient amnesia episodes.
  • The persistent amnesia and clinical presentation were linked to the acute left thalamic infarction.

Implications:

  • This case suggests a potential link between thalamic ischemia and the development of transient global amnesia.
  • Understanding thalamic involvement may offer new insights into the mechanisms of transient and persistent amnesia.
