Sleep problems and mild cognitive impairment among adults aged ≥50 years from low- and middle-income countries
2021
Background-\ud \ud The limited available literature suggests that sleep problems are linked to an increased risk of mild cognitive impairment (MCI). However, this association has been little studied to date in low-income settings.\ud \ud Objective-\ud \ud To investigate the association between sleep problems and MCI in a large sample of adults from six low-and middle-income countries (LMICs).\ud \ud Design-\ud \ud Cross-sectional.\ud \ud Setting-\ud \ud Study on Global Ageing and Adult Health (SAGE).\ud \ud Subjects-\ud \ud 32,715 individuals aged ≥50 years with preservation in functional abilities [age range 50–114 years; 51.7% females].\ud \ud Methods-\ud \ud MCI was defined using the Nat…
Suicide risk in caregivers of people with dementia: a systematic review and meta-analysis.
2022
Abstract Background Interest in physical and mental health outcomes in caregivers of patients with dementia is increasing. However, there is limited data available on the prevalence of suicidal ideation, suicidal attempts, and suicide rates among caregivers of those with dementia. Therefore, we aimed to systematically review these outcomes to address this gap in the literature and thus provide information to inform future policy and intervention for the benefit of caregivers of dementia patients. Methods We searched several databases from inception to the 10th November 2021, for studies investigating suicidal ideation, suicidal attempts, and suicide rates of caregivers of patients with deme…
Wellbeing, resilience, and coping: Are there differences between healthy older adults, adults with mild cognitive impairment, and adults with Alzheim…
2018
The changes that occur with cognitive impairment and Alzheimer's disease could affect psychological aspects unrelated to memory. The purpose of this study is to compare 32 healthy older adults, 31 amnestic mild cognitively impaired (aMCI) adults, and 32 patients diagnosed with Alzheimer's disease (AD), in order to determine whether there are differences in their psychological wellbeing, resilience, and coping strategies. Unifactorial MANOVAS and ANOVAS were performed to analyze the between-group differences. The results reveal that the AD group showed lower levels of resilience and orientation toward problem-solving and greater use of religious strategies. In addition, they had significantl…
CHCH10 mutations in an Italian cohort of familial and sporadic amyotrophic lateral sclerosis patients
2015
Mutations in CHCHD10 have recently been described as a cause of frontotemporal dementia (FTD) comorbid with amyotrophic lateral sclerosis (ALS). The aim of this study was to assess the frequency and clinical characteristics of CHCHD10 mutations in Italian patients diagnosed with familial (n= 64) and apparently sporadic ALS (n= 224). Three apparently sporadic patients were found to carry c.100C>T (p.Pro34Ser) heterozygous variant in the exon 2 of CHCHD10. This mutation had been previously described in 2 unrelated French patients with FTD-ALS. However, our patients had a typical ALS, without evidence of FTD, cerebellar or extrapyramidal signs, or sensorineural deficits. We confirm that CHC…
C9ORF72 hexanucleotide repeat expansions in the Italian sporadic ALS population.
2012
It has been recently reported that a large proportion of patients with familial amyotrophic lateral sclerosis (familial ALS) and frontotemporal dementia (FTD) are associated with a hexanucleotide (GGGGCC) repeat expansion in the first intron of C9ORF72. We have assessed 1,757 Italian sporadic ALS cases, 133 from Sardinia, 101 from Sicily, and 1,523 from mainland Italy. Sixty (3.7%) of 1,624 mainland Italians and Sicilians and 9 (6.8%) of the 133 Sardinian sporadic ALS cases carried the pathogenic repeat expansion. None of the 619 regionally-matched control samples (1,238 chromosomes) carried the expansion. Twenty-five cases (36.2%) had behavioral FTD in addition to ALS. FTD or unspecified d…
Influenza vaccination reduces dementia risk: A systematic review and meta-analysis
2021
Animal models have indicated that influenza vaccination may prevent or delay the onset of dementia. However, the epidemiological evidence in human beings is still limited. Given this background, this systematic review and meta-analysis aimed to summarize the current state of the art of observational studies investigating the association between influenza vaccination and the risk of dementia. We searched Scopus and Pubmed/Medline until 24 September 2021 for studies investigating the risk of dementia by influenza vaccination status. After adjustment for potentially important confounding variables, data were reported as risk ratios (RRs) with 95% confidence intervals (CIs). Among 273 articles …
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…
Therapeutic Drug Monitoring for Patients With Alzheimer Dementia to Improve Treatment With Donepezil
2015
BACKGROUND Aiming to verify that therapeutic drug monitoring has the potential to optimize treatment with acetylcholine esterase inhibitors of patients with Alzheimer dementia, this study investigated whether serum concentrations of donepezil are associated with clinical improvement. METHODS Clinical improvement was measured using the clinical global impression (CGI) scale, and donepezil concentrations were measured in serum by a high-performance liquid chromatographic method with spectrophotometric detection. RESULTS In total, 206 serum samples from 106 patients (49.5% female) were retrospectively available for analysis. Patients included were treated under everyday conditions. Their mean …
