Background: Dementia represents one of the most challenging health problems. Despite intense research, available therapies have thus far only achieved modest results. Deep brain stimulation (DBS) is an effective treatment option for some movement disorders and is under study for psychiatric applications. Recently, diencephalic DBS revealed selective effects on memory functions, another facet of subcortical […]

We studied behavioral variant frontotemporal dementia (bvFTD) using object alternation (OA) as a novel probe of cognition. This task was adopted from animal models and is sensitive to ventrolateral-orbitofrontal and medial frontal function in humans. OA was administered to bvFTD patients, normal controls, and a dementia control group with Alzheimer disease (AD). Two other frontal […]
The influence of aquariums on weight in individuals with dementia
This study assessed whether individuals with dementia who observe aquariums increase the amount of food they consume and maintain body weight. The sample included 70 residents in dementia units within 3 extended care facilities in 2 states. The intervention included the introduction of an aquarium into each common dining area. A total increase of 196.9 […]
Silicon-rich mineral water as a non-invasive test of the ‘aluminum hypothesis’ in Alzheimer’s disease
Davenward, Samantha,
Bentham, Peter,
Wright, Jan,
Crome, Peter,
Job, Deborah,
Polwart, Anthony,
Exley, Christopher
There has been a plausible link between human exposure to aluminum and Alzheimer’s disease for several decades. We contend that the only direct and ethically acceptable experimental test of the ‘aluminum hypothesis’, which would provide unequivocal data specific to the link, is to test the null hypothesis that a reduction in the body burden of […]
Fish consumption and cognitive function among older people in the UK: baseline data from the OPAL study
Dangour, A. D.,
Allen, E.,
Elbourne, D.,
Fletcher, A.,
Richards, M.,
Uauy, R.
Background: Observational epidemiological data suggest that habitual consumption in later life of oily fish, rich in n-3 long-chain polyunsaturated fatty acids (n-3 LCPs), is associated with better cognitive function, slower rates of cognitive decline and a lower risk of dementia. In this paper we present data on baseline fish consumption and cognitive function in cognitively […]
Mental and physical activities delay cognitive decline in older persons with dementia
Cheng, Sheung-Tak,
Chow, Pizza K.,
Song, You-Qiang,
Yu, Edwin C.S.,
Chan, Alfred C.M.,
Lee, Tatia M.C.,
Lam, John H.M.
Objectives: To examine the effects of cognitive stimulation (mahjong) and physical exercise (tai chi [TC]) on cognitive performance in persons with dementia.; Design: Cluster-randomized open-label controlled design.; Setting: Nursing homes.; Participants: One hundred ten residents, most of whom were cholinesterase-inhibitor naive. Inclusion criteria were Mini-Mental State Examination (MMSE) = 10-24 and suffering from at least very mild […]
Women have farther to fall: gender differences between normal elderly and Alzheimer’s disease in verbal memory engender better detection of Alzheimer’s disease in women
Chapman, Robert M.,
Mapstone, Mark,
Gardner, Margaret N.,
Sandoval, Tiffany C.,
McCrary, John W.,
Guillily, Maria D.,
Reilly, Lindsey A.,
DeGrush, Elizabeth
We analyzed verbal episodic memory learning and recall using the Logical Memory (LM) subtest of the Wechsler Memory Scale-III to determine how gender differences in AD compare to those seen in normal elderly and whether or not these differences impact assessment of AD. We administered the LM to both an AD and a Control group, […]
The effect of midlife physical activity on cognitive function among older adults: AGES–Reykjavik Study

Aspelund, T.,
Eiriksdottir, G.,

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 […]
