Psychometric evaluation of the Swedish version of the Person-Centered Care Assessment Tool (P-CAT)
Background: Person-centered care is a multidimensional concept describing good care, especially within aged care and care for people with dementia. Research studies evaluating person-centered care interventions seldom use direct measurement of levels of person-centeredness. Existing scales that measure person-centeredness need further testing. This study evaluated the psychometric properties of the Swedish version of the Person-Centered […]
Alzheimer’s disease (AD) and executive dysfunction. A case-control study on the significance of frontal white matter changes detected by diffusion tensor imaging (DTI)

White matter (WM) changes are frequently seen on structural imaging in AD but the clinical relevance of these changes is uncertain. Frontal WM pathology is often observed upon neuropathological examination in AD. Since frontal cortical/sub-cortical pathology is known to relate to executive dysfunction, the aim was to elucidate if frontal WM changes in AD correlated […]
Longitudinal progression of cognitive decline correlates with changes in the spatial pattern of brain 18F-FDG PET

Mishra, A.,
Riddle, W. R.
Unlabelled: Evaluating the symptomatic progression of mild cognitive impairment (MCI) caused by Alzheimer disease (AD) is practically accomplished by tracking performance on cognitive tasks, such as the Alzheimer Disease Assessment Scale’s cognitive subscale (ADAS_cog), the Mini-Mental Status Examination (MMSE), and the Functional Activities Questionnaire (FAQ). The longitudinal relationships between cognitive decline and metabolic function as […]

Oxidative stress, inflammation, and increased cholesterol levels are all mechanisms that have been associated with Alzheimer’s disease (AD) pathology. Several epidemiologic studies have reported a decreased risk of AD with fish consumption. This pilot study was designed to evaluate the effects of supplementation with omega-3 fatty acids alone (ω-3) or omega-3 plus alpha lipoic acid […]
A randomized controlled trial of estrogen treatment in men with mild cognitive impairment
This randomized, placebo-controlled, cross-over study investigated whether estrogen treatment would have a beneficial effect on tests of verbal memory in men with mild cognitive impairment (MCI). Forty-three men newly diagnosed with MCI were administered a battery of neuropsychological tests before randomly receiving 12 weeks of treatment with estrogen or placebo followed by a 12 week […]

The close correlation between abnormally low pre-mortem cerebrospinal fluid (CSF) concentrations of amyloid-β1-42 (Aβ(1-42)) and plaque burden measured by amyloid imaging as well as between pathologically increased levels of CSF tau and the extent of neurodegeneration measured by MRI has led to growing interest in using these biomarkers to predict the presence of AD plaque […]

Background: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease of motor neurons that results in progressive weakness and death from respiratory failure, commonly within about 3 years. Previous studies have shown association of a locus on chromosome 9p with ALS and linkage with ALS-frontotemporal dementia. We aimed to test whether this genomic region is also […]
Relation of hemoglobin to level of cognitive function in older persons
Shah, Raj C.,
Wilson, Robert S.,
Tang, Yuxiao,
Dong, Xinqi,
Murray, Anne,
Bennett, David A.
Background: While decreased hemoglobin concentration is common in the elderly, the relationship of the entire range of hemoglobin concentrations with cognitive function is not well understood.; Methods: Cross-sectional analyses were conducted utilizing data from community-dwelling, older persons participating in the Rush Memory and Aging Project. Proximate to first available hemoglobin measurement, 21 cognitive tests were […]
