Kotona asuvan muistisairaan henkilön ja hänen läheistensä teknologiaan liittyvät tarpeet ja toiveet
2018
Tutkimuksessa selvitettiin millaisia tarpeita ja toiveita kotona asuvilla muistisairailla ja heidän läheisillään on kotona asumista tukevaan teknologiaan liittyen. Tutkimukseen osallistui 25 kotona asuvaa muistisairasta henkilöä ja 25 heidän läheistään. Metodina käytettiin etnografista tutkimusotetta. Aineistonkeruumenetelminäolivat avoin haastattelua ja havainnointi. Analyysimenetelmänä käytettiin sisällön analyysiä. Tarpeet ja toiveet voitiin luokitella kolmeen pääluokkaan, jotka olivat itsemääräämisoikeuden säilyminen, sosiaalisten suhteiden säilyminen ja liikkumisen oikeus ja turvallisuus. Haasteita olivat yksinäisyyden kokemus, muistin ja toimintakyvyn heikkenemiseen liittyvät ongelmat…
Nutritional screening of patients at a memory clinic--association between patients' and their relatives' self-reports.
2015
Aims and objectives To compare individual reports by patients and relatives (proxy) of the Nutritional Form For the Elderly and relate the Nutritional Form For the Elderly scores to Mini Mental Status Examination scores, weight loss, Body Mass Index, five-point Clock Drawing Test and background variables. Background Undernutrition or risk of undernutrition is a significant problem among people with dementia. A poor nutritional state increases the risk of infections, delayed convalescence after acute illness and reduced quality of life. Design A cross-sectional study. Method Application of the Nutritional Form For the Elderly in addition to clinical nutrition parameters and cognitive tests i…
How we compensate for memory loss in old age: adapting and validating the Memory Compensation Questionnaire (MCQ) for Spanish populations.
2012
Compensating entails using external strategies and mechanisms that help overcome or alleviate the decreasing memory function that comes with age. This study aims to adapt and validate the MCQ in the elderly Spanish population. A total of 403 elderly people aged between 65 and 92 in the city of Valencia (Spain) completed the questionnaire for the validation process. The factorial validity of the scale was tested using confirmatory factor analysis. The result showed a first order five-factor model with 23 items that met the criteria for model fit according to multiple fit indices. As a general conclusion, the adaptation into Spanish provided a reliable and valid measure of compensation in the…
Exposure to N-ethyl-N-nitrosourea in adult mice alters structural and functional integrity of neurogenic sites.
2011
BackgroundPrevious studies have shown that prenatal exposure to the mutagen N-ethyl-N-nitrosourea (ENU), a N-nitroso compound (NOC) found in the environment, disrupts developmental neurogenesis and alters memory formation. Previously, we showed that postnatal ENU treatment induced lasting deficits in proliferation of neural progenitors in the subventricular zone (SVZ), the main neurogenic region in the adult mouse brain. The present study is aimed to examine, in mice exposed to ENU, both the structural features of adult neurogenic sites, incorporating the dentate gyrus (DG), and the behavioral performance in tasks sensitive to manipulations of adult neurogenesis.Methodology/principal findin…
Occurrence of cognitive impairment and dementia in the community: a 9-year-long prospective study.
2008
Objective: To determine incidence rates of non-dementia cognitive impairment, to examine the impact of attrition due to death on the observed incidence estimates, and to compare the observed and corrected estimates of non-dementia cognitive impairment with dementia incidence rates. Methods: A total of 1,435 persons without dementia aged 75+ from the Kungsholmen Project were evaluated for occurrence of dementia over 9 years. A total of 1,070 cognitively unimpaired subjects were also followed using amnestic mild cognitive impairment (aMCI) and other cognitive impairment, no dementia (OCIND) definitions. To correct the observed incidence rates for attrition due to death, cognitive status for s…
Visual memory in Alzheimer patients: effects of practice, retention interval and severity of cognitive decline.
1995
The study was aimed at estimating the effect size of practice, retention interval and dementia severity on free recall performance in Alzheimer patients. Patients met DSM-III-R criteria for dementia of Alzheimer type. Different picture sets were presented on 4 days. The forgetting curves on different days were compared using ANOVA for repeated measurements. Practice had a minor, but significant negative effect on recall performance explaining 1% of the variance in recall performance. The retention interval varied between zero and 24 h explaining 23% of the total variance. Dementia severity explained 52% of the variance. For the development of memory improvement strategies in Alzheimer patie…
Centenarian offspring: A model for understanding longevity
2013
Abstract: A main objective of current medical research is to improve the life quality of elderly people as priority of the continuous increase of ageing population. This phenomenon implies several medical, economic and social problems because of dramatic increase in number of non autonomous individuals affected by various pathologies. Accordingly, the research interest is focused on understanding the biological mechanisms involved in determining the positive ageing phenotype, i.e. the centenarian phenotype. In achieving this goal the choice of an appropriate study models is fundamental. Centenarians have been used as an optimal model for successful ageing. However, this model shows several …
Sedentary behaviours and cognitive function among community dwelling adults aged 50+ years: Results from the Irish longitudinal study of ageing
2020
Background:\ud \ud Sedentary behaviours (SB) are risk factors for poor cardiovascular health and all-cause mortality. However, their role in cognitive health in older adults is unclear. A few studies have examined associations between sedentary behaviours and cognition, but are limited by heterogeneity and insufficient longitudinal analyses. Therefore more robust studies, which would address identified limitations, are needed to accurately determine associations.\ud \ud Method:\ud \ud This study analysed data collected from participants aged 50+ years of The Irish Longitudinal Study of Ageing (TILDA). We conducted cross-sectional linear regression with multivariate imputation analyses of ba…
Un’antologia “sommersa”: "Il libro della memoria" di Gesualdo Bufalino
2018
The paper publishes and analyses as-yet-unpublished documents concerning an anthology on memory in literature, assembled by Gesualdo Bufalino and held in the archive of the Comiso Foundation. The unpublished anthology is accompanied by a letter to Elvira Sellerio, in which Bufalino explains its structure and choices, and by a series of eccentric texts that all revolve around the theme of memory. The drafts and the preparatory cartoons for the anthology in fieri alternate with textual fragments later included into the works of invention, lists of words, aphorisms, autonomous and complete texts (and among these a review as-yet-unpublished of the novel La palazzina di villeggiatura of Enrico J…
Implicit learning and implicit memory in moderate to severe memory disorders
2010
Numerous experimental psychology studies have established firmly that important parts of the human cognitive process operate automatically without the conscious or explicit control of the subjects (9). Such processes can concern memorization of episodes from life in a way that will subsequently have an implicit influence on our behavior (such as decision-making or reaction time). They can equally assist acquisition of more complex knowledge from our surroundings, by the automatic capture of the statistical regularities found in them (see Chapter “Introducing implicit learning: from the laboratory to the real life”, E. Bigand and C. Delbe). This is the way, for example, that a baby learns to…
