BACKGROUND Higher angiotensin-converting enzyme (ACE) activity might increase the risk of Alzheimer's disease by increasing blood pressure, and subsequent development of cerebral small vessel disease (CSVD). Yet, it may also decrease this risk, as it functions to degrade amyloid-β, thereby reducing brain atrophy. OBJECTIVE To examine the cross-sectional(More)
The apolipoprotein E (APOE) gene may act differently in young and old persons, known as antagonistic pleiotropy. We therefore examined the prospective associations between the APOE ε4 allele and cognitive functioning, and the modifying effect of age, in 375 nondemented adults (mean age 57 ± 10 years; follow-up period 3.8 ± 0.2 years) with available data on(More)
IMPORTANCE Studies have shown that both high and low blood pressure (BP) may play a role in the etiology of brain atrophy. High BP in midlife has been associated with more brain atrophy later in life, whereas studies in older populations have shown a relation between low BP and more brain atrophy. Yet, prospective evidence is limited, and the relation(More)
Lower angiotensin-converting enzyme (ACE) activity could increase the risk of Alzheimer’s disease (AD) as ACE functions to degrade amyloid-β (Aβ). Therefore, we investigated whether ACE protein and activity levels in cerebrospinal fluid (CSF) and serum were associated with CSF Aβ, total tau (tau) and tau phosphorylated at threonine 181 (ptau). We included(More)
BACKGROUND Homocysteine may be a modifiable risk factor for cognitive decline and brain atrophy, particularly in older persons. We examined whether homocysteine increased the risk for cognitive decline and brain atrophy, and evaluated the modifying effect of age.

OBJECTIVE To examine the cross-sectional and prospective associations between arterial stiffness and structural brain changes within the Second Manifestations of Arterial Disease-Magnetic Resonance (SMART-MR) study, a prospective cohort study among patients with manifest arterial disease. METHODS Distension measurements of the common carotid arteries and(More)
