CIMT is a good indicator of cardiovascular risk and provides a graded measure of vascular damage: no clear CIMT level above which the cardiovascular risk appears to increase considerably The evidence for arterial stiffness, assessed as carotid distensibility or aortic pulse wave velocity, as an indicator for risk of cardiovascular disease is restricted to subjects with either hypertension or end-stage renal disease or based on small studies in renal transplant patients and elderly. Evidence to indicate that information on carotid intima-media thickness or arterial stiffness, additional to established cardiovascular risk factors, helps to distinguish subjects into those with a high and those with a low absolute risk of cardiovascular disease is limited, but needed. Also, information on the direct comparison of both arterial stiffness measures in their ability to predict cardiovascular disease is needed.

Carotid artery stiffness is no independent risk factor for vascular events in patients with manifest arterial disease. However, in patients with low SBP, decreased carotid stiffness may indicate a decreased risk of vascular events.

The findings of this study suggest that anxiety disorders and executive dysfunctions may be part of the phenotype of M-D patients with a DYT11 mutation, whereas depressive symptoms and semantic fluency impairments may be secondary to suffering from a chronic movement disorder, regardless of DYT11 gene mutation.
