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 […]
Multivariate spatial covariance analysis of 99mTc-exametazime SPECT images in dementia with Lewy bodies and Alzheimer’s disease: utility in differential diagnosis

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 […]

Background: Engagement refers to the act of being occupied or involved with an external stimulus. In dementia, engagement is the antithesis of apathy. Objective: The Comprehensive Process Model of Engagement was examined, in which environmental, personal, and stimulus characteristics impact the level of engagement. Methods: Participants were 193 residents of 7 Maryland nursing with a […]
Can persons with dementia be engaged with stimuli?
Objectives: To determine which stimuli are 1) most engaging 2) most often refused by nursing home residents with dementia, and 3) most appropriate for persons who are more difficult to engage with stimuli. Methods: Participants were 193 residents of seven Maryland nursing homes. All participants had a diagnosis of dementia. Stimulus engagement was assessed by […]
The impact of stimulus attributes on engagement of nursing home residents with dementia
We examined the influence of stimulus attributes on the engagement of 69 nursing home residents with dementia. Specifically,we looked at work-related stimuli versus manipulative block stimuli, and whether the color, size, and material of a stimulus affect the duration and quality of engagement. Engagement was assessed using the Observational Measurement of Engagement (OME). Results revealed […]
The effect of midlife physical activity on cognitive function among older adults: AGES–Reykjavik Study

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 […]
Continuous use of antipsychotics and its association with mortality and hospitalization in institutionalized Chinese older adults: an 18-month prospective cohort study
Chan, Tuen-Ching,
Luk, James Ka-Hay,
Shea, Yat-Fung,
Lau, Ka-Hin,
Chan, Felix Hon-Wai,
Yu, Gabriel Ka-Kui,
Chu, Leung-Wing
Background: Previous meta-analyses have suggested that antipsychotics are associated with increased mortality in dementia patients with behavioral and psychological symptoms (BPSD). Subsequent observational studies, however, have produced conflicting results. In view of this controversy and the lack of any suitable pharmacological alternative for BPSD, this study aimed to investigate the relationship between continuous use of […]
The mini-mental Parkinson’s (MMP) as a cognitive screening tool in people with Parkinson’s disease

Harris, Clare,
Caie, Linda,
Counsell, Carl
Background: Cognitive decline is common in Parkinson’s disease (PD) but may not be adequately identified by the mini-mental state examination (MMSE), which is better suited to Alzheimer’s disease. The mini-mental Parkinson (MMP) examination is a cognitive screening tool designed in French specifically for PD. We aimed to establish the validity and reliability of the English […]
