CONTEXT The recent focus on the development of preventive interventions for Alzheimer disease has fueled the search for biomarkers of presymptomatic disease. Patients with Alzheimer disease and mild cognitive impairment have marked atrophy of the hippocampus and amygdala compared with healthy elderly people. Whether atrophy of these structures is also(More)
The 6-year stability of reading performance was investigated in subjects who were normal at baseline but suspect for dementia at follow-up (MMSE score < or = 23; n = 197), and in a cognitively intact control group (n = 117). The Dutch version of the National Adult Reading Test (DART) was used. The DART-based estimate of IQ appeared to be very stable in(More)
Animal and human autopsy studies suggest that subfields of the hippocampal formation are differentially affected by neuropsychiatric diseases. Therefore, subfield volumes may be more sensitive to effects of disease processes. The few human studies that segmented subfields of the hippocampal formation in vivo either assessed the subfields only in the body of(More)
CONTEXT Strategies for prevention of depression are hindered by lack of evidence about the combined predictive effect of known risk factors. OBJECTIVES To develop a risk algorithm for onset of major depression. DESIGN Cohort of adult general practice attendees followed up at 6 and 12 months. We measured 39 known risk factors to construct a risk model(More)
We compared hippocampal subfield and entorhinal cortex (ERC) volumes between patients with mild cognitive impairment (MCI), Alzheimer's disease (AD), and controls without cognitive impairment. Additionally, we investigated the relation between age and hippocampal subfields and ERC in controls. We performed ultra-high field 0.7 mm(3) 7Tesla magnetic(More)
CONTEXT Laboratory findings have suggested that oxidative stress may contribute to the pathogenesis of Alzheimer disease. Therefore, the risk of Alzheimer disease might be reduced by intake of antioxidants that counteract the detrimental effects of oxidative stress. OBJECTIVE To determine whether dietary intake of antioxidants is related to risk of(More)
OBJECTIVE Cerebral hypoperfusion is among the mechanisms that may explain the association of high blood pressure (BP) with dementia. However, few data are available on the longitudinal association of hypertension and cerebral perfusion. METHODS We examined the longitudinal association of hypertension, BP, and antihypertensive drugs with change in(More)
BACKGROUND Depression may increase risk for Alzheimer disease (AD), but it is not clear whether this risk is mediated by structural brain changes. We determined whether history of depressive episodes and presence of depressive symptoms were associated with smaller hippocampal and amygdalar volumes and with increased risk for incident AD. METHODS Within(More)
BACKGROUND There is evidence that the prevalence of common mental disorders varies across Europe. AIMS To compare prevalence of common mental disorders in general practice attendees in six European countries. METHOD Unselected attendees to general practices in the UK, Spain, Portugal, Slovenia, Estonia and The Netherlands were assessed for major(More)
