Serum cholesterol and incident Alzheimer's disease: findings from the adult changes in thought study.
The purpose of this prospective population-based cohort study was to evaluate associations between high-density lipoprotein cholesterol (HDL) and non-HDL-C levels at specific ages and subsequent Alzheimer's disease (AD) risk. The investigators concluded that people with low (120 mg/dL) and high (210 mg/dL) non-HDL-C levels during their 60s and 70s had modestly higher risk of AD than those with intermediate (160 mg/dL) levels.

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.

Increased health care utilization in dementia subtypes before diagnosis.
The objectives of this study were to identify Alzheimer disease and related dementia (ADRD) subtypes and: (1) characterize all-cause and (2) disease-specific health care utilization (HCU) during the 3 years preceding diagnosis, and (3) determine if HCU varied by ADRD subtype. Among other results, the investigators found that HCU increased over time, was highest in the outpatient setting, and varied by ADRD subtype.

The impact of dementia special care units on quality of care: an instrumental variables analysis.
The purpose of this study was to compare the quality of care following admission to a nursing home (NH) with and without a dementia special care unit (SCU) for residents with dementia. The investigators found that facilities with an SCU provided better quality of care as measured by several validated quality indicators. The authors suggested that given the aging population, policies to promote the expansion and use of dementia SCUs may be warranted.

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.

Underreporting of gender and race/ethnicity differences in NIH-funded dementia caregiver support interventions.
The objective of this study was to determine the inclusion and reporting rates among NIH-funded dementia caregiver support interventions. Findings suggested limited NIH guideline compliance that may reflect a lack of awareness regarding potential gender disparities in caregiving roles. In order to ensure NIH guideline compliance, shared investments from researchers, editors, and reviewers to make certain that group differences are systematically identified and reported are recommended.

Dementia and motor vehicle crash hospitalizations: role of physician reporting laws.
This study sought to determine the effect of physician reporting laws and state licensing requirements on crash hospitalizations among drivers with dementia. It concluded that physician reporting laws, mandated or legally protected, were not associated with a lower likelihood of dementia among crash hospitalized drivers. Vision testing at in-person renewal and in-person renewal requirements were significantly related with a lower prevalence of dementia in hospitalized older drivers.

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.

A cohort study of healthcare utilization in older adults with undiagnosed dementia.
The study objective was to determine healthcare utilization rates among patients with undiagnosed dementia. In terms of healthcare utilization, participants with undiagnosed dementia appear to be an intermediate group between participants with diagnosed dementia and those with no dementia. Participants with diagnosed dementia had 2.5 emergency department visits over 2 years, compared to 1.7 visits for undiagnosed dementia and 0.8 visits for participants with no dementia.

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.

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.

Association of dementia with early rehospitalization among Medicare beneficiaries.
This study examined the question of whether dementia was associated with a greater likelihood of Medicare patients being readmitted to the hospital within 30 days. Using a group of 25,839 hospitalizations, including 3,908 admissions of Me.icare beneficiaries with dementia, it found that those with a dementia diagnosis were more likely (17.8 percent vs. 14.5 percent) to be readmitted within 30 days.

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.
