Objective:
To investigate the potential progression rate of cerebral small vessel disease (CSVD) in brain MRI among neurologically asymptomatic middle-aged individuals with type 1 diabetes.
Research Design And Methods:
A total of 172 individuals with type 1 diabetes were re-examined with brain MRI 7.5 years after their initial visit. Baseline predictors of changes in CSVD, particularly cerebral microbleeds (CMBs) and white matter hyperintensities (WMHs) were analyzed.
Results:
The proportion of individuals with type 1 diabetes with CSVD increased from 36% to 70% (P < 0.001), CMBs increased from 17% to 33% (P < 0.001), and WMHs from 23% to 63% (P < 0.001) at follow-up. The increase in CMBs was associated with baseline systolic blood pressure, HbA1c, and preexisting CMBs. The increases in CSVD and WMHs were associated only with age.
Conclusions:
The prevalence of CSVD doubled over a 7.5-year period in middle-aged individuals with type 1 diabetes.
