Polyphenol-Rich Foods in the Mediterranean Diet are Associated with Better Cognitive Function in Elderly Subjects at High Cardiovascular Risk
2012
Brain oxidative processes play a major role in age-related cognitive decline, thus consumption of antioxidant-rich foods might help preserve cognition. Our aim was to assess whether consumption of antioxidant-rich foods in the Mediterranean diet relates to cognitive function in the elderly. In asymptomatic subjects at high cardiovascular risk (n = 447; 52% women; age 55-80 y) enrolled in the PREDIMED study, a primary prevention dietary-intervention trial, we assessed food intake and cardiovascular risk profile, determined apolipoprotein E genotype, and used neuropsychological tests to evaluate cognitive function. We also measured urinary polyphenols as an objective biomarker of intake. Asso…
Color-coded diffusion-tensor-imaging of posterior cingulate fiber tracts in mild cognitive impairment.
2005
Abstract Different processes like microvascular dysfunction, free radical toxicity, β-amyloid deposits, and Wallerian degeneration can cause functionally relevant disturbances of cerebral neuronal networks by myelin degeneration. Color-coded diffusion-tensor-imaging (ccDTI) allows the structural identification and quantification of myelinated fiber tracts. Particularly, posterior cingulate fiber tracts, which are regarded as important neuronal substrates of the network representing memory processing can be localized only imprecisely by conventional magnetic resonance imaging techniques. The posterior cingulate bundles were assessed by ccDTI in 17 patients with amnestic mild cognitive impair…
Birth cohort differences in cognitive performance in 75- and 80-year-olds: a comparison of two cohorts over 28 years.
2021
Abstract Objective To evaluate cohort differences in cognitive performance in older men and women born and assessed 28 years apart. Methods Data in this study were drawn from two age-homogeneous cohorts measured in the same laboratory using the same standardized cognitive performance tests. Participants in the first cohort were born in 1910 and 1914 and assessed in 1989–1990 (Evergreen project, n = 500). Participants in the second cohort were born in 1938 or 1939 and 1942 or 1943 and assessed in 2017–2018 (Evergreen II, n = 726). Participants in both cohorts were assessed at age 75 and 80 years and were recruited from the population register. Cognitive performance was measured using the Dig…
Effect of cognitive impairment on basic activities of daily living in hip fracture patients: a 1-year follow-up.
2007
Background and aims: To compare changes in basic self-care activities in various cognitive groups of hip fracture patients by the Katz Index of Independence in activities of daily living (ADL). Methods: 117 community-dwelling elderly subjects with acute hip fracture (age 67–92 years), referred to the geriatric unit of Jyvaskyla Central Hospital for rehabilitation, participated in the study. Basic self-care activities were evaluated by the Katz ADL Index and cognition by the Mini-Mental State Examination (MMSE). Results: Prior to hip fracture, the patients in the lowest MMSE group had a significantly lower Katz Index than the other three groups (p<0.001). Disability increased in a statistica…
Estimation of Short Temporal Intervals in Alzheimer's Disease
2000
This study investigated the estimation of short temporal intervals in Alzheimer's disease (AD). Eight patients with dementia of the Alzheimer type, and eight age-matched controls were evaluated in a time-estimation task. The task consisted in the production of three short empty intervals (5, 10, and 25 s). Results indicated that AD patients show deficits both in the accuracy and precision of time judgments: in the three intervals evaluated, the magnitude of absolute error and the variability in time judgments were significantly greater in AD patients than healthy respondents (p < .01). These findings are discussed taking into account the contribution of attentional processes during the perf…
N-Acetylaspartate/Creatine and Choline/Creatine Ratios in the Thalami, Insular Cortex and White Matter as Markers of Hypertension and Cognitive Impai…
2008
International audience; Abstract: Our objective was to investigate the influence of hypertension on N-acetylaspartate (NAA) and choline (Cho) ratios in brain tissues in a community-dwelling elderly population. Brain flexibility was also evaluated with regard to the same metabolite ratios. Proton magnetic resonance spectroscopy (MRS) and the Trail Making Test (TMT) were performed in 80 subjects (75.7 +/- 4 years old) from the Three-City Study. Fifty-eight participants had hypertension. The NAA/creatine (Cr) and Cho/Cr ratios were obtained in the insular cortex, the thalami and the deep periventricular white matter. In addition, the B-A score of the TMT was evaluated. Uniand multi-variate ana…
Vascular Risk Factors in Mild Cognitive Impairment Subtypes. Findings from the ReGAl Project.
2007
Abstract Background and Aim: To investigate the role of vascular risk factors in different subtypes of mild cognitive impairment (MCI) in a multicentric, clinic-based, cross-sectional study. Methods: Two-hundred and seven subjects with MCI were included in the study: 33 with single non-memory MCI (snmMCI), 42 with multiple-domain amnestic MCI (mdMCI-a) and 132 with amnestic MCI (aMCI). Several clinical vascular risk factors and magnetic resonance imaging (MRI) brain lesions were evaluated. Results: snmMCI showed a higher frequency of ischaemic heart disease and of transient ischaemic attack (TIA)/stroke, a higher Hachinski ischaemic score and a higher frequency of white-matter lesions on MR…
Emotional and cognitive adjustment in abused children
1994
Research on the impact of maltreatment on children has increased in the last years, as there is a need to design appropriate treatment strategies. Social, cognitive, and emotional areas may be affected in these children. This research is aimed to study the psychological functioning of child victims, particularly in their emotional and cognitive adjustment. Nineteen children (10.3 years old) with case histories of at least 2 years of physical and emotional parental abuse and a group of 26 nonmaltreated children (9.4 years old) matched in socio-economic characteristics and coming from the same community area were compared in depressive symptomatology and attributional style by using the stand…
Substance-use disorder in high-functioning autism: clinical and neurocognitive insights from two case reports.
2014
Background Low prevalence of substance-use disorder has been reported in adults with autism. However, on a superficial level, adults with high-functioning autism (HFA) display a ‘normal’ façade when they drink alcohol, which may explain why their alcohol dependency is not better diagnosed. Case presentation Here, we report two cases of HFA adults who use alcohol and psychostimulants to cope with their anxiety and improve their cognitive abilities and social skills. We analyze how neurocognitive traits associated with HFA may be potential triggers for substance-use disorder. Conclusion Better identification of autism and its cognitive impairments, which may be vulnerability traits for develo…
Pain and quality of life among residents of Norwegian nursing homes.
2008
Pain is a major problem in the nursing home population, with a prevalence range of 27% to 84%. Pain is an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage (International Association for the Study of Pain, 2008). It has an impact on many aspects of a person's emotional, social, and physical functioning, and on quality of life (QoL) The purpose of this study was to describe pain and QoL in a nursing home population that could self-report pain and to examine the association between QoL and pain in these patients. Pain was measured by a verbal rating scale from "no pain" to "severe pain." Quality of life was measu…
