Minimal hepatic encephalopathy and mild cognitive impairment worsen quality of life in elderly patients with cirrhosis.
Researchers investigated the performance of elderly patients with cirrhosis on tests for minimal hepatic encephalopathy (MHE) and predementia mild cognitive impairment (MCI) and their effects on quality of life (QOL). They found that, in a multicenter study of elderly patients with cirrhosis and controls, the presence of MHE, regardless of MCI, was associated with poor cognition and QOL. They created adjusted norms that defined the high sensitivity of EncephalApp for the detection of MHE in older individuals and validated it in a separate cohort.

Research priorities of caregivers and individuals with dementia with Lewy bodies: an interview study.
The authors investigated the research priorities of individuals and caregivers living with dementia with Lewy bodies (DLB). Through telephone interviews, they found that individuals with DLB and caregivers identified research needs and highlighted DLB symptoms needing additional research. They recommended that funding be informed by the priorities of all relevant stakeholders and support research investigating causes, natural history, biomarkers, and treatment in addition to research targeting themes regarding living with disease.

The Care Ecosystem: promoting self-efficacy among dementia family caregivers.
The authors illustrated specific psychosocial interventions aimed at improving self-efficacy among family caregivers enrolled in the Care Ecosystem, a model of navigated care designed to support persons with dementia and their primary caregivers. They identified three categories of Care Team Navigator intervention: emotional, informational, and instrumental support, which are consistent with a psychosocial approach to building self-efficacy. They concluded that their findings demonstrated how a model of navigated care can positively impact self-efficacy among dementia family caregivers.

National partnership to improve dementia care in nursing homes campaign: state and facility strategies, impact, and antipsychotic reduction outcomes.
This study examines the success of the national partnership campaign to reduce prescription of antipsychotic medications to elderly nursing home residents with dementia. Antipsychotic medications have been shown to increase mortality. Use of these medications had increased 23.9% in dementia patients by 2011. The campaign reduced use by 40.1% to 14.3% by the second quarter of 2019. The campaign measured progress with public reporting of quality measures, increased regulatory scrutiny, and accompanying state and facility initiatives. Sedative-hypnotic medication use also decreased in tandem with antipsychotic reduction suggesting that the campaign increased attention to the use of other risky psychotropic medications.

Accuracy of biomarker testing for neuropathologically defined Alzheimer disease in older adults with dementia
This study is a systematic review of biomarker and test accuracy for identification of Alzheimer Disease (AD) in older adults. Studies with low or medium risk of bias were analyzed, and two reviewers rated risk of bias. Fifteen brain imaging studies and 9 cerebrospinal fluid (CSF) studies met analysis criteria and were included. The meta-analysis found that in methodologically heterogeneous studies of uncertain applicability to typical clinical settings, the biomarkers amyloid PET, 18F-FDG proton emission tomography (PET), and magnetic resonance imaging (MRI) were highly sensitive for neuropathologic AD. Single studies suggested that adding amyloid PET, 18F-FDG PET, and CSF test combinations may add accuracy to clinical evaluation.

Benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia
This is a systematic review and meta-analysis of the benefits and harms of prescription drugs and supplements for treatment of clinical Alzheimer-type dementia (CATD). Studies with low or medium risk of bias (ROB) were analyzed and rated. The analysis concluded there was a slight reduction in short-term cognitive decline with cholinesterase inhibitors and memantime, and cholinesterase inhibitors slightly reduced reported functional decline. There was mostly insufficient evidence on drug treatment of behavioral and psychological symptoms of dementia and on supplements for all outcomes.

Brief cognitive tests for distinguishing clinical Alzheimer-type dementia from mild cognitive impairment or normal cognition in older adults with suspected cognitive impairment.
Researchers summarized evidence on accuracy and harms of brief cognitive tests for clinical Alzheimer-type dementia (CATD) in older adults with suspected cognitive impairment. They encountered the following limitations: small studies, few test metrics being evaluated by multiple studies, and few studies directly comparing different tests, scores, cut points, or test combinations. They concluded that many brief, single cognitive tests accurately distinguish CATD from normal cognition in older adults but are less accurate in distinguishing mild CATD from normal cognition or CATD from mild cognitive impairment.

Association of out-of-pocket costs on adherence to common neurologic medications.
The objective of this training was to determine the association between out-of-pocket costs and medication adherence in 3 common neurologic diseases. The investigators concluded that higher out-of-pocket costs were associated with lower medication adherence in 3 common neurologic conditions. The investigators also observed racial/ethnic disparities and recommended that minority populations receive additional focus in future intervention efforts to improve adherence.

Screening for cognitive impairment in older adults: updated evidence report and systematic review for the US Preventive Services Task Force.
The purpose of this study was to systematically review the test accuracy of cognitive screening instruments and benefits and harms of interventions to treat cognitive impairment in older adults (>/=65 years) to inform the US Preventive Services Task Force. The investigators concluded that screening instruments could adequately detect cognitive impairment. They indicated that there was no empirical evidence, however, that screening for cognitive impairment improved patient or caregiver outcomes or causes harm.

Development and validation of eRADAR: a tool using EHR Data to detect unrecognized dementia.
The goal of this retrospective cohort study was to develop and validate an electronic health record (EHR)-based tool to help detect patients with unrecognized dementia. The tool was named EHR Risk of Alzheimer’s and Dementia Assessment Rule (eRADAR). This study was conducted at Kaiser Permanente Washington (KPWA) using participants in the Adult Changes in Thought (ACT) study who undergo comprehensive testing every 2 years to detect and diagnose dementia and have linked KPWA EHR data. Overall, 1015 ACT visits resulted in a diagnosis of incident dementia, of which 49% were previously unrecognized in the EHR. The final 31-predictor model included markers of dementia-related symptoms, healthcare utilization patterns, and dementia risk factors. The study showed good discrimination in the development interval and validation samples.

Geriatric conditions in patients undergoing defibrillator implantation for prevention of sudden cardiac death: prevalence and impact on mortality.
The researchers sought to determine the prevalence of frailty and dementia among older adults receiving primary prevention implantable cardioverter-defibrillators (ICDs) and to determine the impact of multimorbidity on mortality within 1 year of ICD implantation. They concluded that more than 10 percent of Medicare beneficiaries with heart failure receiving primary prevention ICDs have frailty or dementia. These patients had significantly higher 1-year mortality than those with other common chronic conditions.

Impact of noncaregiving-related stressors on informal caregiver outcomes.
The researchers studied the most stressful events experienced by spouse caregivers of older adults with Alzheimer s disease during a 6-month period. They found that caregivers reported no stressors 21.5% of the time, 1-2 stressors 25% of the time, and 3 stressors 53% of the time with 318 stressors reported in total. They concluded that their results can be used to develop targeted intervention and support strategies for spouse caregivers experiencing non-caregiving related stressors as well as the traditional challenges with caregiving-related issues.

The effects of public reporting on physical restraints and antipsychotic use in nursing home residents with severe cognitive impairment.
The purpose of this paper was to assess whether reductions in physical restraint use associated with quality reporting may have had the unintended consequence of increasing antipsychotic use in nursing home (NH) residents with severe cognitive impairment. Physical restraint use declined significantly from 1999 to 2008 in NH residents with severe cognitive impairment. Correspondingly, antipsychotic use in the same residents increased more in NHs that were subject to public reporting. This analysis suggests that public reporting of physical restraint use had the unintended consequence of increasing use of antipsychotics in NH residents with severe cognitive impairment.
