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)
OBJECTIVE To investigate the independent effects of antihypertensive treatment and blood pressure (BP) levels on physical and mental health status in patients with arterial disease. DESIGN AND SETTING Cross-sectional analyses were conducted within the single-centre Secondary Manifestations of ARTerial disease (SMART) study, in a hospital care setting. (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 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)
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)
High levels of angiotensin-converting-enzyme (ACE) may increase the risk of dementia through blood pressure elevation and subsequent development of cerebral small-vessel disease. However, high ACE levels may also decrease this risk through amyloid degradation which prevents brain atrophy. Within the SMART-MR study, a prospective cohort study among patients(More)
OBJECTIVE Chronic exposure to high levels of angiotensin-converting enzyme (ACE) might increase the risk of hypertensive cardiovascular events. However, little data are available on the association of direct measures of ACE activity with vascular risk and disease. We examined whether serum ACE levels were associated with the risk of recurrent vascular(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. METHODS Within the Second Manifestations of ARTerial disease-Magnetic Resonance study-a(More)
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)
