Time until incident dementia among Medicare beneficiaries using centrally acting or non-centrally acting ACE inhibitors
Hebert, Paul L.,
McBean, Alexander Marshall,
O'Connor, Heidi,
Frank, Barbara,
Good, Charles,
Maciejewski, Matthew L.
Background: Centrally active (CA) angiotensin-converting enzyme inhibitors (ACEIs) are able to cross the blood–brain barrier. Small observational studies and mouse models suggest that use of CA versus non-CA ACEIs is associated with a reduced incidence of Alzheimer’s disease and related dementias (ADRD).; Objective: The aim of this research was to assess the effect of CA […]
Plasma proteomics for the identification of Alzheimer disease
Less-invasive biomarkers for early Alzheimer disease (AD) are urgently needed. The present study aimed to establish a panel of plasma proteins that accurately distinguishes early AD from physiological aging and to compare the findings with previous reports. Fifty-eight healthy controls (CON) and 109 patients with AD dementia were randomly split into a training (40%) and […]
Multivariate spatial covariance analysis of 99mTc-exametazime SPECT images in dementia with Lewy bodies and Alzheimer’s disease: utility in differential diagnosis
Colloby, Sean J,
Taylor, John-Paul,
Davison, Christopher M,
Lloyd, Jim J,
Firbank, Michael J,
McKeith, Ian G,
O'Brien, John T
We examined (99m)Tc-exametazime brain blood flow single-photon emission computed tomography (SPECT) images using a spatial covariance analysis (SCA) approach to assess its diagnostic value in distinguishing dementia with Lewy bodies (DLB) from Alzheimer’s disease (AD). Voxel SCA was simultaneously applied to a set of preprocessed images (AD, n=40; DLB, n=26), generating a series of eigenimages […]
The effect of midlife physical activity on cognitive function among older adults: AGES–Reykjavik Study
Chang, M.,
Jonsson, P. V.,
Snaedal, J.,
Bjornsson, S.,
Saczynski, J. S.,
Aspelund, T.,
Eiriksdottir, G.,
Jonsdottir, M. K.,
Lopez, O. L.,
Harris, T. B.,
Gudnason, V.,
Launer, L. J.
Background: There are few studies on the long-term associations of physical activity (PA) to cognition. Here, we examine the association of midlife PA to late-life cognitive function and dementia.; Methods: The sample consisted of a population-based cohort of men and women (born in 1907-1935) participating in the Age Gene/Environment Susceptibility-Reykjavik Study. The interval between the […]
Evidence for neurocognitive plasticity in at-risk older adults: the experience corps program
Carlson, M. C.,
Erickson, K. I.,
Kramer, A. F.,
Voss, M. W.,
Bolea, N.,
Mielke, M.,
McGill, S.,
Rebok, G. W.,
Seeman, T.,
Fried, L. P.
Objective: To determine whether Experience Corps (EC), a social service program, would improve age-vulnerable executive functions and increase activity in brain regions in a high-risk group through increased cognitive and physical activity.; Methods: Eight community-dwelling, older female volunteers and nine matched wait-list controls were recruited to serve in the ongoing EC: Baltimore program in three […]
Diagnosis of Alzheimer’s disease patients with rapid cognitive decline in clinical practice: interest of the Deco questionnaire
Carcaillon, L.,
Berrut, G.,
Sellal, F.,
Dartigues, J. F.,
Gillette, S.,
Pere, J. J.,
Bourdeix, I.
Background: Patients with Alzheimer’s disease (AD) who deteriorate rapidly are likely to have a poorer prognosis. There is a clear need for a clinical assessment tool to detect such a decline in newly diagnosed patients.; Objective: To identify the predictive factors of rapid cognitive decline (RCD) in a cohort of patients with mild to moderate […]
Olive oil and cognition: results from the three-city study
Berr, Claudine,
Portet, Florence,
Carrière, Isabelle,
Akbaraly, Tasnime N.,
Feart, Catherine,
Gourlet, Véronique,
Combe, Nicole,
Barberger-Gateau, Pascale,
Ritchie, Karen
Background: Olive oil is a major component of the Mediterranean diet suggested to be beneficial to counteract Alzheimer’s disease.; Aim Of the Study: Our objective was to examine the association between olive oil use, cognitive deficit and cognitive decline in a large elderly population.; Methods: We followed 6,947 subjects with a brief baseline food frequency […]
Dietary intake of vitamin D and cognition in older women: a large population-based study
Annweiler, C.,
Schott, A.M.,
Rolland, Y.,
Blain, H.,
Herrmann, F. R.,
Beauchet, O.
Background: Serum vitamin D concentrations are associated with global cognitive function among older adults. The benefits of vitamin D intake to treat or prevent cognitive impairment remain unknown. The objective of this cross-sectional study was to determine whether weekly dietary intake of vitamin D could be associated with global cognitive performance among older adults.; Methods: […]
