Structural brain changes and all-cause mortality in the elderly population-the mediating role of inflammation.

While MRI brain changes have been related to mortality during ageing, the role of inflammation in this relationship remains poorly understood. Hence, this study aimed to investigate the impact of MRI changes on all-cause mortality and the mediating role of cytokines. All-cause mortality was evaluated in 268 community dwelling elderly (age 65-83 years) in the MEMO study (Memory and Morbidity in Augsburg elderly).

Functional consequences of subcortical white matter lesions and MRI-defined brain infarct in an elderly general population.

The impact of single and combined effects of subcortical white matter lesions (WMLs) and magnetic resonance imaging (MRI)-defined brain infarct on activities of daily living (ADL), depression, and health status perception was analyzed in community-dwelling elderly individuals. The study included 268 participants from the Memory and Morbidity in Augsburg Elderly (MEMO) project, a population-based study on individuals aged 65 to 83 years, conducted in Augsburg, Germany. Cerebral MRI was performed, and 2 geriatric performance tests, scales to assess ADL, depressive symptoms, and self-perceived health status were assessed.

Association between cytokines and cerebral MRI changes in the aging brain.

The association between cytokines (IL-1 beta, sIL-4R, IL-6, IL-8, IL-10, IL-12, TNF-alpha) and subcortical white matter lesions, cortical atrophy and lacunar infarctions of the aging brain was investigated among 268 elderly community participants. Single pro- and anti-inflammatory cytokines were neither associated with WML nor with atrophy and lacunar infarction. An association between atrophy and the chemokine-cytokine factor (containing sIL-4R, IL-6, IL-8) remained significant after adjustment for age, gender, education, depressive symptoms, diabetes mellitus, cardiovascular diseases (stroke, TIA, myocardial infarction, myocardial insufficiency, arrhythmic heart), hypertension, body-mass index, smoking status and aggregation inhibitors as opposed to single cytokines.

Single and combined effects of cerebral white matter lesions and lacunar infarctions on cognitive function in an elderly population.

Background: This study is to investigate the association between single and combined vascular brain changes (white matter lesions [WMLs], lacunar infarctions) and the cognitive domains of memory, processing speed, and motor function in the elderly adults.

Methods: In a sample of 268 participants aged 65-83 years of the MEMO (Memory and Morbidity in Augsburg Elderly) population-based study in Augsburg, Germany, cerebral magnetic resonance imaging (MRI) was performed and a detailed neuropsychological test battery applied. Analysis of covariance determined the effects of vascular brain changes on domains of cognitive functioning.

Relation of cerebral small-vessel disease and brain atrophy to mild Parkinsonism in the elderly.

The association between cerebral small-vessel disease, brain atrophy, and the risk and severity of mild parkinsonian signs (MPS) remains unclear. The objective of this study is to examine the effect of lacunar brain infarcts, cerebral white matter lesions (WMLs), and cortical atrophy on the risk and severity of MPS. This study is a cross-sectional community-based cohort study comprising 268 subjects, 65 to 83 years of age, residing in the Augsburg region of southern Germany, and without contraindications for magnetic resonance imaging (MRI) of the brain.

Relation of plasma thyroid-stimulating hormone levels to vascular lesions and atrophy of the brain in the elderly.

Context: Recent studies suggest that thyroid disease is associated with cardiovascular and peripheral vascular disease. However, little is known about the underlying pathophysiology and the relation with cerebrovascular disease or brain atrophy in the elderly.

Objective: To determine if plasma thyroid-stimulating hormone (TSH) levels are associated with vascular brain changes and cortical atrophy in the elderly.

Functional and cognitive consequences of silent stroke discovered using brain magnetic resonance imaging in an elderly population.

Objectives: To evaluate the prevalence of silent stroke and its associated consequences on physical, cognitive, and emotional functioning in an elderly population.

Design: Population-based cross-sectional survey.

Setting: The Memory and Morbidity in Augsburg Elderly project in the Augsburg region of southern Germany.
