Abstract

Objective

Cerebral Small Vessel Disease (CSVD) has not been systematically studied in patients with Transient Global Amnesia (TGA). We aimed to investigate the CSVD burden in patients with TGA and its relationship with TGA recurrence.

Methods

We retrospectively examined 69 patients diagnosed with TGA in a single center between January 2015 and November 2023. The overall CSVD burden and single CSVD imaging markers, including enlarged perivascular spaces in the hippocampus (H-EPVS), were measured in each patient and compared with those in 69 age- and sex-matched healthy controls. Multivariate logistic regression was performed to determine independent predictors of recurrence.

Results

Of the 69 included patients, 40 (58%) were female, and the median age was 67 years (range 42-83 years). Twenty-one patients (30.4%) showed dot-like hippocampal hyperintensities on diffusion-weighted imaging (DWI). The mean follow-up was 51 months. Sixteen patients (23.2%) experienced TGA recurrence. The burden of overall CSVD, lacunes, WMH, EPVS, and extensive H-EPVS was higher in TGA patients than in controls. TGA patients who experienced recurrence had a heavier overall CSVD burden, lower frequency of hippocampal DWI hyperintensities, and longer follow-up duration than those who had with single episode. In the multivariate analysis, only follow-up duration was an independent predictor of TGA recurrence.

Conclusion

The overall CSVD burden and extensive H-EPVS burden were higher in patients with TGA than healthy controls. Follow-up duration but not overall CSVD burden may predict TGA recurrence.
