Sturm, Volker
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 […]

Background: Alzheimer’s disease is characterized by the presence of cortical amyloid-beta (Aβ) protein plaques, which result from the sequential action of β-secretase and γ-secretase on amyloid precursor protein. Semagacestat is a small-molecule γ-secretase inhibitor that was developed as a potential treatment for Alzheimer’s disease.; Methods: We conducted a double-blind, placebo-controlled trial in which 1537 patients […]
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 […]
The effect of midlife physical activity on cognitive function among older adults: AGES–Reykjavik Study

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 […]
