Our aim was to investigate the extent of white matter tissue damage in patients with early Alzheimer disease (AD) using diffusion tensor magnetic resonance imaging (DTI). Although AD pathology mainly affects cortical grey matter, previous magnetic resonance imaging (MRI) studies showed that changes also exist in the white matter (WM). However, the nature of(More)
OBJECTIVE To investigate whether patients diagnosed with amnestic mild cognitive impairment (MCI) have also impairment in attention/executive functions, and therefore to clarify whether all subcomponents of executive control are equally affected in MCI. BACKGROUND MCI refers to the transitional state between normal aging and dementia. Amnestic MCI is(More)
OBJECTIVES To determine whether adding cognitive impairment to frailty improves its predictive validity for adverse health outcomes. DESIGN Four-year longitudinal study. SETTING The French Three-City Study. PARTICIPANTS Six thousand thirty community-dwelling persons aged 65 to 95. MEASUREMENTS Frailty was defined as having at least three of the(More)
Reduced semantic fluency performances have been reported in the preclinical phase of Alzheimer's disease (AD). To investigate the cognitive processes underlying this early deficit, this study analyzed the verbal production of predemented subjects for the animals category with the qualitative parameters related to clustering (i.e. the ability to generate(More)
Previous research suggests that the neuropsychological deficits in Alzheimer's disease (AD) are different from that of vascular dementia (VaD), especially with respect to memory, language and executive functions, but negative findings were reported. Our objective was to clarify the cognitive syndrome in AD and VaD in the early stage of these disorders. We(More)
Category fluency tests were administered at baseline and after 3 and 5 years on two subgroups of subjects from a population-based cohort of elderly subjects: 52 cases of incident possible and probable Alzheimer's disease (AD) and 104 age- and education-matched subjects who remained nondemented. Quantitative and qualitative features of category fluency were(More)
To determine whether abnormalities of the perisinusoidal space of Disse are present in the liver of diabetic patients with microangiopathy, an ultrastructural stereologic study of the space of Disse was performed in six insulin-treated diabetics with severe performed in six insulin-treated diabetics with severe proliferative retinopathy and six(More)
Gender differences in visuospatial cognition favoring men are larger in tasks requiring active information manipulation than in tasks requiring passive storage. This study was designed to determine whether male advantage in active manipulation of visuospatial information can still be evidenced in Alzheimer's disease (AD). Twenty male and 20 female AD(More)
The extent to which patients' reports of maladjustment is influenced by depressive symptoms was estimated in 25 acute depressed patients responding to pharmacotherapy. Their social adjustment over the same four-month period immediately prior to hospitalization was assessed on two separate occasions: firstly when they were acutely depressed, and again a mean(More)
The Free and cued selective reminding test (FCSRT) is one of the most effective neuropsychological test used to assess verbal memory in elderly people with memory problems. There are currently two lists of words: the initial French version (list A) and an alternative one (list B). However, diagnosing early Alzheimer's disease in memory clinics often(More)
