«Our results demonstrate that aortic arch pulse wave velocity is a highly significant independent predictor of subsequent white matter hyperintensity volume and provides a distinct contribution — along with systolic blood pressure, hypertension treatment, congestive heart failure and age — in predicting risk for cerebrovascular disease,» Dr. King said.

The results showed that aortic arch pulse wave velocity helped predict white matter hyperintensity volume, independent of the other demographic and cardiovascular risk factors.

Patients showing gadolinium in the vitreous chamber at the later timepoint tended to be of older age, have a history of hypertension, and have more bright spots on their brain scans, called white matter hyperintensities, that are associated with brain aging and decreased cognitive function.

Authors examined the association between SVD and AD pathology by looking at magnetic resonance imaging (MRI)- based microbleeds (MB), white matter hyperintensities (WMH) and lacunes (which are measures for SVD) along with certain protein levels in cerebrospinal fluid (CSF) which reflect AD pathophysiology in patients with AD, VaD and healthy control patients.

However, in recent years, clinicians in Japan noticed that patients with a history of multiple administrations of Gd - CM showed areas of high intensity, or hyperintensity, on MRI in two brain regions: the dentate nucleus (DN) and globus pallidus (GP).

Dr. Kanda noted that because patients with multiple sclerosis tend to undergo numerous contrast - enhanced brain MRI scans, the hyperintensity of the DN seen in these patients may have more to do with the large cumulative gadolinium dose than the disease itself.

«The hyperintensity of DN and GP on unenhanced T1WI may be due to gadolinium deposition in the brain independent of renal function, and the deposition may remain in the brain for a long time,» Dr. Kanda suggested.

The precise clinical ramifications of hyperintensity are not known, but hyperintensity in the DN has been associated with multiple sclerosis, while hyperintensity of the GP is linked with hepatic dysfunction and several diseases.

The hyperintensity of both the DN and the GP correlated with the number of Gd - CM administrations.
