Clinical care and unmet needs of individuals with dementia with Lewy bodies and caregivers: an interview study.
Investigators researched the clinical care preferences of individuals living with dementia and caregivers, particularly dementia with Lewy bodies (DLB). Twenty individuals with DLB and 25 caregivers were interviewed via a semistructured questionnaire. The investigators concluded that improving care for individuals with DLB and their families will require a multipronged strategy including education for non-specialist care providers, increasing specialty care access, improved clinical care services, research to support disease prognosis and treatment decisions, and local and national strategies for enhanced caregiver support.

Continuity of nursing care in home health: impact on rehospitalization among older adults with dementia.
The objective of this retrospective cohort study was to examine the association between continuity of nursing care in home health care (HHC) and rehospitalization among persons with dementia (PWD). Multiple years of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency was used. Findings showed that wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.

Changes in the agreement between the Minimum Data Set and hospital Medicare claims measures of dementia.
The objective of this study was to examine the agreement between a clinical Minimum Data Set measure of dementia and a diagnosis of dementia documented on a hospital claim across three points in time. A second objective was to examine the extent to which the agreement varied by age, sex, and race/ethnicity. Findings showed that hospital claims for patients aged 66–75 were less likely to be accurate than those for other age groups and suggests that physicians do not always look for signs of dementia in younger adults. Additionally, Asian patients were less likely to have a diagnosis of dementia documented during hospitalization, which could be related to language barriers between patients and clinicians.

Characteristics associated with feeding tube placement: retrospective cohort study of Texas nursing home residents with advanced dementia.
The purpose of this retrospective cohort study was to investigate resident-level, provider-type, nursing home (NH), and regional factors associated with feeding tube (FT) placement in advanced dementia. The investigators concluded that regional, race, and ethnic variations in prevalence of FT use among NH residents suggested opportunities for clinicians and policy makers to improve the quality of end-of-life care by especially considering other palliative care measures for minorities living in border towns.

Biomarker use for dementia with Lewy body diagnosis: survey of US experts.
Researchers investigated clinical practice patterns of dementia with Lewy body (DLB) diagnostic criteria. An anonymous survey was sent to 38 center of excellence investigators inquiring about clinical use of diagnostic tests/biomarkers. They found that neuropsychological testing and MRI remained the most widely used diagnostic tests by DLB specialists. Other tests, particularly, indicative biomarkers, are used only selectively. They recommended research to validate existing potential DLB biomarkers, to develop new biomarkers, and to investigate mechanisms to improve DLB diagnosis.

Dementia caregivers' experiences and reactions to remote activity monitoring system alerts.
Technology-based tools, including remote activity monitoring (RAM) systems, have been proposed as valuable aids for family caregivers of people with dementia. Previous analyses have shown limited effects of these systems and highlighted a number of barriers, including false alarms. In this study, the investigators used data from an ongoing embedded mixed method randomized controlled intervention to describe patterns of alerts and their association with receipt of the RAM system and caregiver outcomes.

Predicting diagnosis of Alzheimer's disease and related dementias using administrative claims.
The objective of this study is to see if a better predictive model could be created for earlier diagnosis of Alzheimer disease and related dementia (ADRD) using the amount of health care utilization (HCU) in individuals prior to diagnosis. A case-control study was conducted including individuals with and without mild cognitive impairment who were diagnosed between 2011 and 2014. They were matched to controls without ADRD and were able to obtain moderate accuracy.

Severe hypoglycaemia, mild cognitive impairment, dementia and brain volumes in older adults with type 2 diabetes: the Atherosclerosis Risk in Communities (ARIC) cohort study.
In this study, the investigators aimed to evaluate the link between severe hypoglycaemia and domain-specific cognitive decline, smaller brain volumes and dementia in adults with type 2 diabetes. The investigators concluded that their results demonstrated a strong link between severe hypoglycaemia and poor cognitive outcomes, suggesting a need for discussion of appropriate diabetes treatments for high-risk older adults.

Association between groundwater lithium and the diagnosis of bipolar disorder and dementia in the United States.
This study examined the association between groundwater lithium and the diagnoses of bipolar disorder and dementia in the United States, with adjustment for local health care resources and demographics. Data on groundwater lithium concentrations was collected by the US Geological Survey, and diagnoses were identified from inpatient hospital, long-term care, and other therapy claims files from several sources. The results of the study indicate that, in spite of the substantial variations in groundwater lithium exposure, no significant association between exposure and the risk of bipolar disorder or dementia after adjustment for county-level demographics and health care resource was found. The authors note that therapeutic lithium doses are orders of magnitude larger than groundwater lithium concentrations, which makes a true causal relationship between groundwater lithium and mental health dubious.

Representation in the care planning process for nursing home residents with dementia.
This study examined the participation of residents, family members, or representatives in nursing home (NH) long-term care planning for residents with cognitive impairment. A large for-profit NH system was used to recruit study participants. A sample of 18,552 long-stay NH residents in 2016 were surveyed. Of residents with no cognitive impairment, 8% had family or representative participation in care planning, compared with 26% of residents with severe impairments. Family participation was greater in NHs with more social workers.

State of science: bridging the science-practice gap in aging, dementia and mental health.
This article describes why new models of care in aging, dementia, and mental health diffuse inadequately into the healthcare systems and communities where they might benefit older adults. The investigators review a general framework for the diffusion of innovations and highlight the importance of other features of innovations that deter or facilitate diffusion.

Does cognitive training prevent cognitive decline?: A systematic review.
This review summarized evidence on the effects of cognitive training on cognitive performance and incident dementia outcomes for adults with normal cognition or mild cognitive impairment (MCI). It concluded that results for populations with MCI suggested no effect of training on performance (low-strength and insufficient evidence). Evidence for prevention of cognitive decline or dementia was insufficient.

Over-the-counter supplement interventions to prevent cognitive decline, mild cognitive impairment, and clinical Alzheimer-type dementia: a systematic review.
This review summarizes the evidence on efficacy and harms of over-the-counter (OTC) supplements to prevent or delay cognitive decline, mild cognitive impairment (MCI), or clinical Alzheimer-type dementia in adults with normal cognition or MCI but no dementia diagnosis. It concluded that evidence is insufficient to recommend any OTC supplement for cognitive protection in adults with normal cognition or MCI.

Nursing home chain affiliation and its impact on specialty service designation for Alzheimer disease.
Specialty care units (SCUs) in nursing homes (NHs) grew in popularity during the 1990s to attract residents while national policies and treatment paradigms changed. Alzheimer disease has consistently been the dominant form of SCU. This study explored the extent to which chain affiliation, which is common among NHs, affected SCU bed designation.
