Background and PurposeaaTransient global amnesia (TGA) is characterized by sudden anterograde
and retrograde amnesia lasting for up to 24 hours. Diffusion-weighted magnetic resonance
imaging (DWI) in cases of TGA and ischemia demonstrates a high frequency of high
signal intensities restricted to the hippocampus, and this has been proposed as an etiology of
TGA. The aims of this study were to characterize the DWI and single-photon-emission computed
tomography (SPECT) findings during the acute and recovered phases of TGA and to correlate
the findings with oculomotor abnormalities.
MethodsaaFive consecutive patients with a clinical diagnosis of TGA underwent DWI and
SPECT of the brain within 24 hours after symptom onset and again 3 days later. Eye movements
were also recorded using three-dimensional video-oculography.
ResultsaaIn all patients, DWI disclosed small punctuate (1-3 mm), high-signal lesions in the
lateral portion of the hippocampus. The initial SPECT also revealed hypoperfusion in the cerebellar
vermis, which had recovered by the follow-up examination. Three patients showed saccadic
hypermetria or impaired smooth pursuit only during the acute phase.
ConclusionsaaOur patients with TGA showed cerebellar vermian hypoperfusion in addition to
ischemic insults to the lateral hippocampus. The oculomotor abnormalities observed in our patients
support the occurrence of cerebellar dysfunction during the TGA attack.
