Comparison of the baseline characteristics based on the site of DWI lesion.

Values are number (%) unless indicated.Abbreviations: DWI = diffusion-weighted imaging; IQR = interquartile range; TGA = transient global amnesia.aFor one patient from group with hippocampal body lesions, only data concerning age, gender, laterality of DWI lesion, time of onset to DWI and time of onset to SPECT were available.bP values were obtained using the Kruskall-Wallis test or the Fisher's exact test as appropriate.cWhen patients were able to explain the reasons for their hospitalizations and to form new memories, we considered their episode of TGA to be over.
