Highlights

Intracranial arterial calcifications are very common in memory clinic patients.
Cardiovascular risk factors are differentially related to intimal and medial calcifications.
Intracranial arterial calcifications are associated with stroke.
Intimal calcifications are also associated with myocardial infarction.
Intracranial arterial calcifications are not associated with cognitive outcomes.

Abstract

Background and aims

we know little about clinical outcomes of arterial calcifications. This study investigates the risk factors of intracranial artery calcifications and its association with cardiovascular disease and cognitive function.

Methods

patients were recruited from a Dutch memory clinic, between April 2009 and April 2015. The intracranial internal carotid artery (iICA) and basilar artery were analysed on the presence of calcifications. Calcifications in the iICA were also assessed on severity and location in the tunica intima or tunica media. Using logistic regression, risk factors of intracranial artery calcifications were analysed, as well as the association of these calcifications with cardiovascular disease, cognitive function and type of cognitive disorder (including subjective cognitive impairment, mild cognitive impairment and dementia). Cognitive function was assessed with the Cambridge Cognitive Examination.

Results

1992 patients were included (median age: 78.2 years, ±40% male). The majority of patients had calcifications in the iICA (±95%). Basilar artery calcifications were less prevalent (±8%). Risk factors for cerebral intracranial calcifications were age (p < 0.001), diabetes mellitus (medial iICA, p = 0.004), hypertension (intimal iICA, p < 0.001) and basilar artery, p = 0.019) and smoking (intimal iICA, p = 0.008). iICA calcifications were associated with stroke and intimal calcifications also with myocardial infarction. Intracranial artery calcifications were not associated with cognitive function or type of cognitive disorder.

Conclusion

the majority of memory clinic patients had intracranial artery calcifications. Cardiovascular risk factors are differentially related to medial or intimal iICA calcifications. iICA calcifications were associated with myocardial infarction and stroke, but not with cognitive outcomes.
