Being overweight in midlife is associated with lower cognitive ability and steeper cognitive decline in late life
Dahl, Anna,

Berg, Stig,

Reynolds, Chandra A.,
Pedersen, Nancy L.
Background: Although an increasing body of evidence links being overweight in midlife with an increased risk for dementia in late life, no studies have examined the association between being overweight in midlife and cognitive ability in late life. Our aim was to examine the association between being overweight in midlife as measured by body mass […]

Certain micronutrients are protective against cognitive decline. We examined whether there is any uniform pattern of circulating micronutrients cross-culturally that are associated with successful cognitive aging. For the U.S. sample, we used the stored serum/plasma of 115 participants, collected in Oregon, USA. The Okinawa sample consisted of 49 participants selected using similar inclusion criteria as […]
Longer duration of hormonal contraceptive use predicts better cognitive outcomes later in life
Background: The cognitive effects of postmenopausal hormone therapy (HT) have been studied extensively, but little is known about the relationship between premenopausal hormone use and cognition. Hormonal contraceptive use vs. nonuse may be a potential factor influencing cognitive processes in midlife. The aim of this study is to explore the effect of modification of hormone […]
Preserving Identity and Planning for Advance Care (PIPAC): preliminary outcomes from a patient-centered intervention for individuals with mild dementia
Hilgeman, Michelle M.,
Allen, Rebecca S.,
Snow, A. Lynn,
Durkin, Daniel W.,
DeCoster, Jamie,
Burgio, Louis D.
Objectives: The purpose of this pilot study was to conduct limited-efficacy testing of the newly developed Preserving Identity and Planning for Advance Care (PIPAC) intervention on self-reported and proxy-reported emotional and health-related outcomes of individuals in the early stages of dementia.; Method: A two-group comparison design was implemented. Blocked randomization was used to assign individuals […]
Acute caffeine administration effect on brain activation patterns in mild cognitive impairment
Haller, Sven,
Montandon, Marie-Louise,
Rodriguez, Cristelle,
Moser, Dominik,
Toma, Simona,
Hofmeister, Jeremy,
Sinanaj, Indrit,
Lovblad, Karl-Olof,
Giannakopoulos, Panteleimon
Previous studies showed that acute caffeine administration enhances task-related brain activation in elderly individuals with preserved cognition. To explore the effects of this widely used agent on cognition and brain activation in early phases of cognitive decline, we performed a double-blinded, placebo-controlled functional magnetic resonance imaging (fMRI) study during an n-back working memory task in […]
Cognitive, emotional, and social benefits of regular musical activities in early dementia: randomized controlled study
Sarkamo, T.,
Tervaniemi, M.,
Laitinen, S.,
Numminen, A.,
Kurki, M.,
Johnson, J. K.,
Rantanen, P.
PURPOSE OF THE STUDY: During aging, musical activities can help maintain physical and mental health and cognitive abilities, but their rehabilitative use has not been systematically explored in persons with dementia (PWDs). Our aim was to determine the efficacy of a novel music intervention based on coaching the caregivers of PWDs to use either singing […]
Differences in regional brain metabolism associated with specific formulations of hormone therapy in postmenopausal women at risk for AD
Silverman, Daniel H. S.,
Geist, Cheri L.,
Kenna, Heather A.,
Williams, Katherine,
Wroolie, Tonita,
Powers, Bevin,
Brooks, John,
Rasgon, Natalie L.
Differential cerebral metabolic effects of various hormone therapy formulations, and their associations with cognitive status, remain to be established. The principal aim of the current study was to assess relationships between regional cerebral metabolism and estrogen-based hormone therapies. Postmenopausal women (n=53) at elevated risk for Alzheimer’s disease (AD) were on estrogen-containing hormone therapy for at […]
Voxel-level comparison of arterial spin-labeled perfusion MRI and FDG-PET in Alzheimer disease
Chen, Y.,
Wolk, D. A.,
Reddin, J. S.,
Korczykowski, M.,
Martinez, P. M.,
Musiek, E. S.,
Newberg, A. B.,
Julin, P.,
Arnold, S. E.,
Greenberg, J. H.,
Detre, J. A.
Objective: We compared the ability of arterial spin labeling (ASL), an MRI method that measures cerebral blood flow (CBF), to that of FDG-PET in distinguishing patients with Alzheimer disease (AD) from healthy, age-matched controls.; Methods: Fifteen patients with AD (mean age 72 ± 6 years, Mini-Mental State Examination score [MMSE] 20 ± 6) and 19 […]
