MRI

In Wernicke-Korsakoff Syndrome patients, MRI may show the following changes [1]:

  • Atrophy of mamillary bodies.
  • Hyperintense signals in the mesial dorsal thalami
  • Hyperintense signals in the periaqueductal grey matter
  • On T1 C+ MRI, contrast enhancement in the aforementioned regions.
  • DWI/ADC: Restricted diffusion in the same regions.
  • MR spectroscopy: Reduced N-acetylaspartic acid and increased lactate concentrations.
