Ding G, Hua S, Chen J, Yang S, Xie R. Does cognitive decline/dementia increase Delirium risk after stroke? Psychogeriatrics 2021; 21:605-611. [PMID: 34018278 DOI: 10.1111/psyg.12720] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2021] [Revised: 04/20/2021] [Accepted: 05/09/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND Delirium is a common contributor to mortality and hospital costs in stroke patients. Different observational studies have showed inconsistent results regarding the association between cognitive decline/dementia and delirium after acute stroke. Therefore, we performed this meta-analysis with the aim of determining whether cognitive decline/dementia is related to the risk of delirium after acute stroke. METHODS We systematically searched PubMed, Embase, Google Scholar, and Web of Science for relevant studies from inception to September 2020. We calculated the pooled odds ratio (OR) with 95% confidence interval (CI) by using fixed or random effects models based on heterogeneity measured by the I2 index. RESULTS The association between cognitive decline/dementia and post-stroke delirium was examined in 13 studies with 3183 participants. After pooled analysis, we found that cognitive decline/dementia was significantly associated with susceptibility to delirium in post-stroke patients (OR = 3.70, 95%CI: 2.90-4.71, P < 0.001). Subgroup analysis suggested that cognitive decline/dementia was associated with an increased risk of delirium in Caucasians (OR = 3.73, 95%CI: 2.73-5.11, P < 0.001), non-Caucasians (OR = 3.65, 95%CI: 2.50-5.33, P < 0.001), samples with <200 subjects (OR = 3.70, 95%CI: 2.17-6.31, P < 0.001), samples with ≥200 subjects (OR = 3.70, 95%CI: 2.82-4.85, P < 0.001), studies published in 1990-2009 (OR = 3.17, 95%CI: 1.48-6.77, P = 0.003), and studies published in 2010-2020 (OR = 3.76, 95%CI: 2.92-4.86, P < 0.001). CONCLUSIONS We identified an association between cognitive decline/dementia and the risk of developing delirium. Cognitive decline/dementia may be a promising predictor for delirium in post-stroke patients.

Gerontology 2021; 67:599-607. [PMID: 33789299 PMCID: PMC8619779 DOI: 10.1159/000514298] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 01/06/2021] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Predisposing and precipitating factors for delirium for the elderly, over the age of 65 years, are known, but not for the very old, over 80 years. As the society is getting older and evermore patients will reach >80 years, more evidence of the factors and their contribution to delirium is required in this patient group. METHODS In the course of 1 year, 3,076 patients above 80 years were screened prospectively for delirium based on a Delirium Observation Screening (DOS) scale, Intensive Care Delirium Screening Checklist (ICDSC), and a DSM (Diagnostic and Statistical Manual)-5 nursing instrument (ePA-AC) construct. Relevant predisposing and precipitating factors for delirium were assessed with a multiple regression analysis. RESULTS Of 3,076 patients above 80 years, 1,285 (41.8%) developed a delirium, which led to twice prolonged hospitalization (p < 0.001), requirement for subsequent assisted living (OR 2.2, CI: 1.73-2.8, p < 0.001), and increased mortality (OR 24.88, CI: 13.75-45.03, p < 0.001). Relevant predisposing factors were dementia (OR 15.6, CI: 10.17-23.91, p < 0.001), pressure sores (OR 4.61, CI: 2.74-7.76, p < 0.001), and epilepsy (OR 3.65, CI: 2.12-6.28, p < 0.0001). Relevant precipitating factors were acute renal failure (4.96, CI: 2.38-10.3, p < 0.001), intracranial hemorrhage (OR 8.7, CI: 4.27-17.7, p < 0.001), and pleural effusions (OR 3.25, CI: 1.77-17.8, p < 0.001). CONCLUSION Compared to the general delirium rate of approximately 20%, the prevalence of delirium doubled above the age of 80 years (41.8%) due to predisposing factors uncommon in younger patients.

Abstract
People with early-onset dementia have a potential risk of being marginalised with respect to care and social support as a result of the blame and stigma associated with their condition, and because they have reduced access to treatment options and postdiagnostic care. The limited use of community services and the resulting psychological implications are two key issues facing the group and their caregivers. Early diagnosis, behavioural therapies such as talking therapy, meaningful Montessori activities and friendly community services tailored to meet the needs of people with early-onset dementia are relationship-centred care approaches that could be implemented in practice, using the ‘Senses Framework’ to promote an enriched supportive environment of care with zero tolerance for marginalisation and discriminatory tendencies. Support for caregivers is invaluable in controlling behavioural changes in people with early-onset dementia. A combined approach involving pharmacological and behavioural interventions could be used in severe mood and behavioural changes.

Abstract
Alzheimer's disease (AD) is an age-related progressive dementia, which is increasing in prevalence world-wide. Typically affecting short-term memory at onset, this devastating illness advances to impair all aspects of cognition, as well as non-cognitive domains. Although much effort has been made in recent years to develop disease-modifying treatments, medications which provided promising results in pre-clinical research have so far faltered in human clinical trials. Attention has recently shifted into trying to identify preventative measures that may delay the onset of the illness. Preventative factors include physical activity, proper diet, cognitive stimulation and the management of conditions such as hypertension, diabetes and obesity. However, it remains imperative to identify approaches that may help patients already diagnosed with the illness. Alongside pharmacological research, much work has been done on uncovering strategies which may slow down the progression of AD. This review aims to summarize evidence supporting or refuting methods impacting on the progression of the disease. AD remains a chronic and serious condition, therefore any intervention delaying the onset of moderate/severe symptoms will have a significant impact on patients and their families.

Abstract
The present review aims to highlight this intricate syndrome, regarding diagnosis, pathophysiology, etiology, prevention, and management in elderly people. The diagnosis of delirium is based on clinical observations, cognitive assessment, physical, and neurological examination. Clinically, delirium occurs in hyperactive, hypoactive, or mixed forms, based on psychomotor behavior. As an acute confusional state, it is characterized by a rapid onset of symptoms, fluctuating course and an altered level of consciousness, global disturbance of cognition or perceptual abnormalities, and evidence of a physical cause. Although pathophysiological mechanisms of delirium remain unclear, current evidence suggests that disruption of neurotransmission, inflammation, or acute stress responses might all contribute to the development of this ailment. It usually occurs as a result of a complex interaction of multiple risk factors, such as cognitive impairment/dementia and current medical or surgical disorder. Despite all of the above, delirium is frequently under-recognized and often misdiagnosed by health professionals. In particular, this happens due to its fluctuating nature, its overlap with dementia and the scarcity of routine formal cognitive assessment in general hospitals. It is also associated with multiple adverse outcomes that have been well documented, such as increased hospital stay, function/cognitive decline, institutionalization and mortality. In this context, the early identification of delirium is essential. Timely and optimal management of people with delirium should be performed with identification of any possible underlying causes, dealing with a suitable care environment and improving education of health professionals. All these can be important factors, which contribute to a decrease in adverse outcomes associated with delirium.

Abstract
The objective was to present an overview of methods to examine the validity of the minimum data set of the interRAI Acute Care (interRAI AC). Because of the multidimensional character of this comprehensive geriatric assessment tool, clinimetric testing of the interRAI AC can be more complex than that of one-dimensional instruments. Thus to facilitate testing of the interRAI AC, we translated this complexity into a structured methodological framework that outlines procedures to assess various lines of evidence. Our framework combined traditional clinimetric techniques and the standards of psychological testing. For each line of evidence, examples of hypotheses and research questions were summarized. Future clinimetric testing can use these guidelines as a basis to obtain and provide a wide and diverse body of evidence.

Abstract
This report describes the outcomes of 17 long-term care residents who were participating in a nursing intervention study. The residents were evacuated for 5 days due to a severe summer storm that caused widespread power outages. These residents were seen the day of the storm and three times per week for 2 weeks following their return to the nursing home. More than half of the participants had significant changes in their NEECHAM Confusion Scale scores (n = 11) and modified Confusion Assessment Method scores (n = 9) scores, suggesting the onset of delirium. Two participants were hospitalized within the 2 weeks of the evacuation. One participant died unexpectedly. This report provides a rare look into the negative effects of a short-term evacuation due to a natural disaster.
