BACKGROUND/AIMS: Although some patients with primary progressive aphasia (PPA) exhibit novel or improved skills after the onset of dementia, these changes have yet to be quantified. Therefore, this study systematically explored and identified the emergence of positive behaviours after dementia onset. METHODS: This study included 48 carers of patients with PPA: 12 nonfluent/agrammatic PPA (nfvPPA), 22 semantic variant PPA (svPPA), and 14 logopenic variant PPA (lvPPA)...

BACKGROUND/AIMS: Although the Mini-Mental State Examination (MMSE), Clinical Dementia Rating-Sum of Boxes (CDR-SOB), and neuropsychological batteries are widely used for evaluating cognitive function, it remains elusive which instrument best reflects the longitudinal disease progression in amnestic mild cognitive impairment (aMCI) and probable Alzheimer disease (AD). We investigated whether changes in these three instruments over time correlate with loss of cortical gray matter volume (cGMV)...

BACKGROUND: Acupressure has been used to manage agitation in people with dementia because it is safe and inexpensive. However, its effect on agitation and at the biochemical level is uncertain. METHODS: This randomized controlled trial examined the effect of acupressure on agitation, as measured by the Cohen-Mansfield Agitation Inventory (CMAI); and on salivary cortisol, as measured at baseline (T0) and in the 3rd (T1), 5th (T2), and 8th (T3) weeks. There were 119 agitated residents with dementia randomized into 3 groups: acupressure (n = 39), sham (n = 41), and usual-care group (n = 39)...

AIMS: The present study set out to investigate the relation of the high-density lipoprotein cholesterol (HDL-C) level to cognitive performance and its interplay with key markers of cognitive reserve in a large sample of older adults. METHODS: We assessed tests of working memory, immediate and delayed cued recall in 701 older adults from Amazonas, Brazil. The HDL-C level was derived from fasting blood samples. In addition, we interviewed individuals on their education, past occupation, and cognitive leisure activity...

BACKGROUND: In the future, an increase in health care needs in the elderly is expected. Reports on unmet care needs of the oldest old with cognitive disorders are pending. This study aims at exploring unmet needs in the oldest old primary care patients with mild cognitive impairment (MCI) and dementia. Furthermore, the association between sociodemographic and clinical factors and unmet needs ought to be analyzed. METHODS: Based on the study "Needs, Health Service Use, Costs and Health-Related Quality of Life in a Large Sample of Oldest-Old Primary Care Patients (85+)" (AgeQualiDe), 749 patients (unimpaired, MCI, and dementia) aged 85 years and older, their relatives (n = 421), and general practitioners (GPs) (n = 607) were assessed...

BACKGROUND/AIMS: Driving cessation is associated with significant morbidity in older people. People with mild cognitive impairment (MCI) may be at particular risk of this. Very little research has examined driving in this population. Given this, we sought to identify predictors of driving cessation in people with MCI. METHODS: One hundred and eighty-five people with MCI were recruited from 9 memory clinics around Australia. People with MCI and their carers reported their driving status and completed measures of cognition, function, neuropsychiatric symptoms, and medication use at regular intervals over a 3-year period...

BACKGROUND: Recent research suggests using an imaginary version of the Timed Up and Go test (TUG) for a first assessment of cognitive impairment. By using the time difference between a real (TUGr) and an imagined (TUGi) TUG task, the objective of this study was to examine the effect of cognitive impairment on motor imagery ability. METHODS: Fifty-two participants (mean age 69.3 ± 4.0 years) with mild cognitive impairment or subjective cognitive impairment were included in this study...

BACKGROUND/AIMS: Prior studies of late-onset Alzheimer disease (AD) have reported that cerebrospinal fluid (CSF) tau levels correlate with hippocampal/medial temporal lobe atrophy. These findings suggest that CSF tau indices in AD may reflect tau-related neurodegeneration in the medial temporal lobe. However, it remains uncertain whether elevated CSF tau levels in the clinically heterogeneous subtypes of early-onset AD (EOAD; amnestic, posterior cortical atrophy [PCA], and logopenic progressive aphasia [LPA]) are attributable to similar underlying mechanisms...

BACKGROUND: Alzheimer disease (AD) is a progressive neurodegenerative disease with a complex multifactorial etiology. Here, we aim to identify a biomarker pool comprised of genetic variants and blood biomarkers as predictor of AD risk. METHODS: We performed a case-control study involving 108 cases and 159 non-demented healthy controls to examine the association of multiple biomarkers with AD risk. RESULTS: The APOE genotyping revealed that ε4 allele frequency was significantly high (p value = 0...

BACKGROUND/AIMS: Verbal fluency is impaired in patients with frontotemporal dementia (FTD) and primary progressive aphasia (PPA). This study explored qualitative differences in verbal fluency (clustering of words, switching between strategies) between FTD and PPA variants. METHODS: Twenty-nine patients with behavioral variant FTD (bvFTD) and 50 with PPA (13 nonfluent/agrammatic, 14 semantic, and 23 logopenic) performed a semantic and letter fluency task. Clustering (number of multiword strings) and switching (number of transitions between clustered and nonclustered words) were recorded by two independent raters...

BACKGROUND/AIMS: The prognostic accuracy of mild cognitive impairment (MCI) in clinical settings is debated, variable across criteria, cut-offs, subtypes, and follow-up time. We aimed to estimate the prognostic accuracy of MCI and the MCI subtypes for dementia using three different cut-off levels. METHODS: Memory clinic patients were followed for 2 (n = 317, age 63.7 ± 7.8) and 4-6 (n = 168, age 62.6 ± 7.4) years. We used 2.0, 1.5, and 1.0 standard deviations (SD) below the mean of normal controls (n = 120, age 64...
