Purpose: Osteoporosis is an important senile disease and has significant relationship with ischemic stroke and cerebral small vessel disease (SVD). Correlation between bone mineral density (BMD) and cerebral white matter hyperintensity on magnetic resonance imaging were analyzed to investigate the relationship between osteoporosis and cerebral SVD.
Methods: Medical records of acute stroke patients with age ≥ 65 years were retrospectively collected from single center. Cerebral white matter hyperintensity was classified into two categories, periventricular white matter hyperintensity (PWMH) and deep white matter hyperintensity (DWMH), and the severity was graded according to maximal lesion size. Association between the clinical factors including BMD and the severity of cerebral white matter hyperintensity was analyzed.
Results: Four hundred eight patients were included in the study. High severity grade of both MWMH and DWMH was independently correlated with low BMD. Additionally, high PWMH grade was correlated with old age and high serum homocysteine. High DWMH grade was correlated with old age, atrial fibrillation history and high serum total calcium.
Conclusion: Low BMD was associated with a high severity of cerebral white matter hyperintensity in elderly Asian stroke patients, independent of other clinical factors.
