Cognition-Oriented Treatments for Older Adults: a Systematic Overview of Systematic Reviews

AbstractCognition-oriented treatments – commonly categorized as cognitive training, cognitive rehabilitation and cognitive stimulation – are promising approaches for the prevention of cognitive and functional decline in older adults. We conducted a systematic overview of meta-analyses investigating the efficacy of cognition-oriented treatments on cognitive and non-cognitive outcomes in older adults with or without cognitive impairment. Review quality was assessed by A Measurement Tool to Assess Systematic Reviews 2 (AMSTAR). We identified 51 eligible reviews, 46 of which were included in the quantitative synthesis. The confide nce ratings were “moderate” for 9 (20%), “low” for 13 (28%) and “critically low” for 24 (52%) of the 46 reviews. While most reviews provided pooled effect estimates for objective cognition, non-cognitive outcomes of potential relevance were more sparsely reported. The mean effect estimat e on cognition was small for cognitive training in healthy older adults (mean Hedges’g = 0.32, range 0.13–0.64, 19 reviews), mild cognitive impairment (mean Hedges’g = 0.40, range 0.32–0.60, five reviews), and dementia (mean Hedges’g = 0.38, range 0.09–1.16, seven reviews), and small for cognitive stimulation in dementia (mean Hedges’g = 0.36, range 0.26–0.44, five reviews). Meta-regression revealed that higher AMSTAR sc...

DEMENTIA symptoms can be difficult to spot in its early stages, although there are a number of warning signs to look out for - including memory loss. These are the five most common early symptoms of Alzheimer's disease. Should you speak to a doctor about your dementia risk?

Authors: Wang Z, Shen L, Wang Y, Huang S Abstract Alzheimer's disease (AD) is a progressive neurodegenerative disease, which is considered the most common type of dementia worldwide. The aim of the present study was to identify key microRNAs (miRNAs/miRs) and mRNAs affecting the pathogenesis of AD, which may be developed as promising biomarkers for the early diagnosis or targeted therapy of patients with AD. Integrative analysis was performed on 12 representative miRNA datasets and three mRNA datasets of the blood from patients with AD, in order to identify differentially expressed (DE)miRNAs and DEmRNAs. Subsequen...

CONCLUSIONS: These results indicate that the CAIDE dementia risk score is associated with cortical thickness and cognitive function at midlife in a low-risk population. These data provide insight into subclinical structural and functional changes occurring during midlife associated with future risk for the development of dementia.

Authors: Polychronidou E, Avramouli A, Vlamos P Abstract Misfolded proteins result when a protein follows the wrong folding pathway. Accumulation of misfolded proteins can cause disorders, known as amyloid diseases. Unfortunately, some of them are very common. The most prevalent one is Alzheimer's disease. Alzheimer's disease is a neurodegenerative disorder and the commonest form of dementia. The current study aims to assess the impact of somatic mutations in PSEN1 gene. The said mutations are the most common cause of familial Alzheimer's disease. As protein functionality can be affected by mutations, the study of ...

In this study, the EEOS treatment in hyperhomocysteinemic rats has showed significant improvement in spatial learning and working memory performance. The EEOS treatment further increased nitric oxide bioavailability and significantly altered all serum and brain biochemical parameters in a dose-dependent manner. The docking analysis revealed that among all the phytoconstituents of Ocimum sanctum compound (IX), molludistin has showed good inhibitory activity against S-adenosyl homocysteine, thus preventing homocysteine formation and may be responsible for potential effects of EEOS against HHcy-induced VaD. From our results, ...

Authors: Robakis NK Abstract Alzheimer's disease (AD) is the most common type of dementia caused by severe neurodegeneration in the hippocampus and neocortical regions of the brain. In addition to neurodegeneration, AD brains contain high levels of amyloid plaques (APs) and neurofibrillary tangles (NFTs) which are used as neuropathological hallmarks of the disorder. Despite intense research efforts, the mechanism(s) of the AD neurodegeneration are imperfectly understood, hampering efforts for the development of efficient therapeutics. Furthermore, failure of clinical trials to benefit AD patients suggests that AD h...

The objective of this review study is to highlight the effectiveness of brief cognitive tests (BCT) in the case of dementia and Alzheimer's disease screening. Authors' future work will focus on the application of BCT in MCI diagnosis and evaluation. PMID: 32468467 [PubMed - in process]

Authors: Salis C, Papageorgiou L, Papakonstantinou E, Hagidimitriou M, Vlachakis D Abstract Neurodegenerative diseases lead to the death of nerve cells in the brain or the spinal cord. A wide range of diseases are included within the group of neurodegenerative disorders, with the most common ones being dementia, Alzheimer's, and Parkinson's diseases. Millions of older people are suffering from such pathologies. The global increase of life expectancy unavoidably leads to a consequent increase in the number of people who will be at some degree affected by neurodegenerative-related diseases. At this moment, there is n...

Authors: Newman K Abstract Novel multimodal sensing study that has been installed and tested in a geriatric psychiatry inpatient unit is reviewed. Perspectives and experiences of behavioural and psychological symptoms of dementia are also examined. Further, the Spare a Thought for Dementia Through the Your Story My Story campaign, a project that seeks to amplify empowering stories from persons living with dementia and their friends and family carers in order to combat stigma and show carers that they are not alone in their journeys, is also discussed.
