Progression of Cerebral Small Vessel Disease Among Neurologically Asymptomatic Middle-Aged Individuals With Type 1 Diabetes

Diabetes CarePublished Prospective cohort study

Authors' conclusion

The prevalence of CSVD doubled over a 7.5-year period in middle-aged individuals with type 1 diabetes.

Study context

Population
Neurologically asymptomatic middle-aged individuals with T1D
Participants
172 individuals
Exposure
Baseline vs 7.5-year follow-up
Outcome
Progression of cerebral small vessel disease (CSVD) on brain MRI
Follow-up
7.5 years
Methodological detailsfollow-up brain MRI after 7.5 years
  • Follow-up brain MRI after 7.5 years

Main finding

As reported in the abstract

Proportion with CSVD

P < 0.001

Observational data: associations, not effects.

Further findings

Proportion with cerebral microbleeds (CMBs) · 7.5 years

P < 0.001

Proportion with white matter hyperintensities (WMHs) · 7.5 years

P < 0.001

Baseline predictors of change

Increase in cerebral microbleeds (CMBs) associated with baseline systolic blood pressure, HbA1c and preexisting CMBs
Increases in cerebral small vessel disease (CSVD) and white matter hyperintensities (WMHs) associated only with age
