Intensive LDL-cholesterol lowering therapy and neurocognitive function
2017
The key lipid-lowering target is to achieve guideline-recommended low-density lipoprotein cholesterol (LDL-C) levels, usually by using statins. The new treatment strategies for lipid-lowering therapy include using proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors as an exciting approach to reduce residual risk of cardiovascular diseases (CVD). However, concerns about possible adverse effects, including neurocognitive disorders, were issued by the Food and Drug Administration (FDA). The current disputable evidence does not allow definite conclusions as to whether statins contribute to, or cause, clinically meaningful cognitive impairment. Some evidence indicates a high rate of…
Nurses experience of aromatherapy use with dementia patients experiencing disturbed sleep patterns. An action research project
2013
The purpose of this study was to gain an insight into nurses' experiences of incorporating aromatherapy into the care of residents suffering from dementia, anxiety and disturbed sleep patterns. Twenty-four residents and twelve nurses from four nursing homes participated in an action research study. The use of lavender augustofolia essential oil diffused nightly was perceived as an effective care modality reducing insomnia and anxiety in this patient cohort. Nurses experienced some negative attitudes among colleagues because they considered aromatherapy as not evidence based. Nurses require greater access to evidence based use of Aromatherapy. Further research is needed to study how smell ca…
Beta-adrenoceptor density and subtype distribution in cerebellum and hippocampus from patients with Alzheimer's disease
1993
beta-Adrenoceptor density and beta 1- and beta 2-subtype distribution were examined in hippocampi and cerebella from patients with Alzheimer's disease (AD/SDAT). Tissues from age-, sex and post-mortem delay matched non-demented patients served as controls. The total beta-adrenoceptor density as evaluated in saturation experiments with the hydrophilic radioligand [3H]CGP 12177 was higher in hippocampal (36-39 fmol/mg protein) than cerebellar tissues (20-21 fmol/mg), however, no differences were found in either brain region between AD/SDAT patients and controls. Subtype distribution using the highly selective beta 1-adrenoceptor antagonist CGP 20712A revealed a slightly higher proportion of b…

Increased hippocampal head diffusivity predicts impaired episodic memory performance in early Alzheimer's disease
2010
Recent neuroanatomical and functional neuroimaging studies indicate that the anterior part of the hippocampus, rather than the whole structure, may be specifically involved in episodic memory. In the present work, we examined whether anterior structural measurements are superior to other regional or global measurements in mapping functionally relevant degenerative alterations of the hippocampus in Alzheimer's disease (AD). Twenty patients with early AD (MMSE 25.7+/-1.7) and 18 healthy controls were studied using magnetic resonance and diffusion-tensor imaging. Using a regions-of-interest analysis, we obtained volumetric and diffusivity measures of the hippocampal head and body-tail-section …
Amygdala-hippocampal atrophy and memory performance in dementia of Alzheimer type.
1997
The aim of the present study was to examine the involvement of brain structures, especially the amygdala-hippocampal complex, in dementia of Alzheimer type (DAT), and to assess the relation of amygdala-hippocampal atrophy with memory dysfunction. 14 patients with DAT and 10 healthy age-matched controls were examined with different neuropsychologic tests including the UCLA-Auditory Verbal Learning Test. MRI was performed with a conventional 1.5-tesla scanner. Atrophy was found in many brain structures of demented subjects in comparison with healthy age-matched controls. The volumes of amygdala-hippocampal complexes and of the temporal lobes of demented subjects were more reduced than the tot…
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…
The symptom of low mood in the prodromal stage of mild cognitive impairment and dementia: a cohort study of a community dwelling elderly population.
2011
Objective: To investigate the symptom of low mood as a predictor of mild cognitive impairment (MCI) and its progression to dementia, taking into account: i) MCI severity, ii) time of assessment, iii) interaction with other factors. Methods: 764 cognitively healthy elderly living in the community, from the Kungsholmen Project. Participants were assessed by direct interview to detect low mood. Subjects were then followed for six years to identify those who developed MCI. People with incident MCI were followed for a further three years to assess progression to dementia. Results: People with low mood at baseline had a 2.7-fold (95% Confidence Interval [CI] 1.9-3.7) increased risk of developing …
Relationship between mobility and cognitive impairment in patients with Alzheimer's disease.
2019
Alzheimer's disease (AD) is usually accompanied by impairments to mobility, performance of the basic activities of daily life (ADL), and progressive cognitive decline. We analyzed the relationship between cognitive performance and related cognitive subdomains and mobility.All AD patients of the recruited individuals were living in nursing homes; they underwent a blood analysis, cognitive examination by using the Mini-Mental State Examination, functional evaluation of independence in the ADLs with Barthel score and Katz index, and mobility assessment with the elderly mobility scale.The mean sample age was 84 years and majority were women; more than 60% of the participants had severe cognitiv…
Lexical and conceptual components of stem completion priming in patients with Alzheimer's disease
1999
This study evaluated the hypothesis of dissociation between normal lexical but deficient conceptual repetition priming in patients with Alzheimer's disease (AD). For this purpose, we administered to patients with AD and age-matched normal controls the Stem Completion task. In Experiment 1, the level of word processing during study was manipulated by requiring subjects to count vowels (graphemic condition) or generate meanings (semantic condition) of target words. In Experiment 2, the presentation modality was varied during the study to obtain an intramodal and crossmodal repetition priming. Probably due to a floor effect of performance in the graphemic condition, in Experiment 1, AD patient…
