RESUMEN
INTRODUCTION: Potentially inappropriate medications (PIMs) cause adverse events and death. We evaluate the Care Ecosystem (CE) collaborative dementia care program on medication use among community-dwelling persons living with dementia (PLWD). METHODS: Secondary analysis of a randomized clinical trial (RCT) comparing CE to usual care (UC) on changes in PIMs, over 12 months between March 2015 and May 2020. Secondary outcomes included change in number of medications, clinically relevant PIMs, and anti-dementia medications. RESULTS: Of 804 PLWD, N = 490 had complete medication data. The CE resulted in significantly fewer PIMs compared to UC (-0.35; 95% CI, -0.49 to -0.20; P < 0.0001). Number needed to prevent an increase in 1 PIM was 3. Total medications, PIMs for dementia or cognitive impairment, CNS-active PIMs, anticholinergics, benzodiazepines, and opioids were also fewer. Anti-dementia medication regimens were modified more frequently. CONCLUSION: The CE medication review intervention embedded in collaborative dementia care optimized medication use among PLWD. HIGHLIGHTS: Compared to usual care (UC), the Care Ecosystem (CE) medication review intervention prevented increases in potentially inappropriate medications (PIMs). Use of anticholinergics, benzodiazepines, and opioids were significantly reduced, with a trend for antipsychotics. Anti-dementia medications were adjusted more frequently. The CE medication review intervention embedded in collaborative dementia care optimized medication use.

BACKGROUND AND PURPOSE: The faster rates of cognitive decline and predominance of atypical forms in early-onset Alzheimer's disease (EOAD) suggest that neuropsychiatric symptoms could be different in EOAD compared to late-onset AD (LOAD); however, prior studies based on non-biomarker-diagnosed cohorts show discordant results. Our goal was to determine the profile of neuropsychiatric symptoms in EOAD and LOAD, in a cohort with biomarker/postmortem-confirmed diagnoses. Additionally, the contribution of co-pathologies was explored. METHODS: In all, 219 participants (135 EOAD, 84 LOAD) meeting National Institute on Aging and Alzheimer's Association criteria for AD (115 amyloid positron emission tomography/cerebrospinal fluid biomarkers, 104 postmortem diagnosis) at the University of California San Francisco were evaluated. The Neuropsychiatric Inventory-Questionnaire (NPI-Q) was assessed at baseline and during follow-up. The NPI-Q mean comparisons and regression models adjusted by cognitive (Mini-Mental State Examination) and functional status (Clinical Dementia Rating Sum of Boxes) were performed to determine the effect of EOAD/LOAD and amnestic/non-amnestic diagnosis on NPI-Q. Regression models assessing the effect of co-pathologies on NPI-Q were performed. RESULTS: At baseline, the NPI-Q scores were higher in EOAD compared to LOAD (p < 0.05). Longitudinally, regression models showed a significant effect of diagnosis, where EOAD had higher NPI-Q total, anxiety, motor disturbances and night-time behavior scores (p < 0.05). No differences between amnestics/non-amnestics were found. Argyrophilic grain disease co-pathology predicted a higher severity of NPI-Q scores in LOAD. CONCLUSIONS: Anxiety, night-time behaviors and motor disturbances are more severe in EOAD than LOAD across the disease course. The differential patterns of neuropsychiatric symptoms observed between EOAD/LOAD could suggest a pattern of selective vulnerability extending to the brain's subcortical structures. Further, co-pathologies such as argyrophilic grain disease in LOAD may also play a role in increasing neuropsychiatric symptoms.

Importance: Few health systems have adopted effective dementia care management programs. The Care Ecosystem is a model for delivering care from centralized hubs across broad geographic areas to caregivers and persons with dementia (PWDs) independently of their health system affiliations. Objective: To determine whether the Care Ecosystem is effective in improving outcomes important to PWDs, their caregivers, and payers beyond those achieved with usual care. Design, Setting, and Participants: A single-blind, randomized clinical trial with a pragmatic design was conducted among PWDs and their caregivers. Each PWD-caregiver dyad was enrolled for 12 months between March 20, 2015, and February 28, 2017. Data were collected until March 5, 2018. Study interventions and assessments were administered over the telephone and internet by clinical and research teams in San Francisco, California, and Omaha, Nebraska. Of 2585 referred or volunteer PWD-caregiver dyads in California, Iowa, or Nebraska, 780 met eligibility criteria and were enrolled. A total of 512 PWD-caregiver dyads were randomized to receive care through the Care Ecosystem and 268 dyads to receive usual care. All eligible PWDs had a dementia diagnosis; were enrolled or eligible for enrollment in Medicare or Medicaid; and spoke English, Spanish, or Cantonese. Analyses were intention-to-treat. Intervention: Telephone-based collaborative dementia care was delivered by a trained care team navigator, who provided education, support and care coordination with a team of dementia specialists (advanced practice nurse, social worker, and pharmacist). Main Outcomes and Measures: Primary outcome measure: Quality of Life in Alzheimer's Disease based on caregiver's rating of 13 aspects of PWD's well-being (including physical health, energy level, mood, living situation, memory, relationships, and finances) on a 4-point scale (poor to excellent). Secondary outcomes: frequencies of PWDs' use of emergency department, hospitalization, and ambulance services; caregiver depression (score on 9-Item Patient Health Questionnaire; higher scores indicate more severe depression); and caregiver burden (score on 12-Item Zarit Burden Interview; higher scores indicate more severe caregiver burden). Results: The 780 PWDs (56.3% female; mean [SD] age, 78.1 [9.9] years) and 780 caregivers (70.9% female; mean [SD] age, 64.7 [12.0] years) lived in California (n = 452), Nebraska (n = 284), or Iowa (n = 44). Of 780 dyads, 655 were still active at 12 months, and 571 completed the 12-month survey. Compared with usual care, the Care Ecosystem improved PWD quality of life (B, 0.53; 95% CI, 0.25-1.30; P = .04), reduced emergency department visits (B, -0.14; 95% CI, -0.29 to -0.01; P = .04), and decreased caregiver depression (B, -1.14; 95% CI, -2.15 to -0.13; P = .03) and caregiver burden (B, -1.90; 95% CI, -3.89 to -0.08; P = .046). Conclusions and Relevance: Effective care management for dementia can be delivered from centralized hubs to supplement usual care and mitigate the growing societal and economic burdens of dementia. Trial Registration: ClinicalTrials.gov identifier: NCT02213458.

Many studies attempting to compare the clinical features in different dementia syndromes have attempted to control for overall disease severity using neuropsychological or functional measures. However, these measures may not give equivalent estimates of disease severity. We examined a functional measure of severity (Clinical Dementia Rating scale [CDR] scores) in patients with Alzheimer disease (AD, n = 23), frontotemporal dementia (FTD, n = 24), and semantic dementia (SD, n = 25) who were matched for age and Mini-Mental State Examination (a neuropsychological measure of severity). Total CDR scores were significantly worse in the FTD group compared with both AD and SD patients, whose total CDR scores were similar to each other. FTD showed no difference in memory or orientation compared with AD but did show more impairment in judgment and problem solving, community affairs, home and hobbies, and personal care compared with AD and SD. Thus, in FTD the CDR reveals functional impairments in a wide variety of domains that are more severe than those seen in AD or SD patients with an equivalent Mini-Mental State Examination.

BACKGROUND: Early-onset familial Alzheimer's disease (EOFAD) is linked to mutations in three autosomal dominant genes: PS1, PS2 and APP. The clinical presentation and age of onset of mutations is variable. OBJECTIVES: The aim of this report is to describe a novel PS1 mutation believed to be causal for a very early onset of AD. METHODS: This is a case history using information from medical records, relative interviews and genetic testing results to describe the pre-clinical prodrome and clinical course of a patient with EOFAD. RESULTS: A previously undescribed G206V mutation in PS1 was found in the proband. CONCLUSION: The G206V mutation in PS1 is probably causal of a case of EOFAD with significant premorbid features.
