Deprescribing of Antihypertensive Medications and Cognitive Function in Nursing Home Residents.

Importance: Antihypertensive medication deprescribing is common among nursing home residents, yet its association with cognitive decline remains uncertain.

Objective: To investigate the association of deprescribing antihypertensive medication with changes in cognitive function in nursing home residents.

Design, Setting, And Participants: This cohort study using a target trial emulation approach included VA long-term care residents aged 65 years or older with stays of at least 12 weeks from 2006 to 2019.

eConsultation for Deprescribing Among Older Adults: Clinician Perspectives on Implementation Barriers and Facilitators.

Background: Electronic consultations (eConsults) enable asynchronous consultation between primary care providers (PCPs) and specialists. eConsults have been used successfully to manage a variety of conditions and have the potential to help PCPs manage polypharmacy and promote deprescribing.

Objective: To elicit clinician perspectives on barriers/facilitators of using eConsults for deprescribing among older adults within a university health network.

Which older adults are at highest risk of prescribing cascades? A national study of the gabapentinoid-loop diuretic cascade.

Background: Prescribing cascades are important contributors to polypharmacy. Little is known about which older adults are at highest risk of experiencing prescribing cascades. We explored which older veterans are at highest risk of the gabapentinoid (including gabapentin and pregabalin)-loop diuretic (LD) cascade, given the dramatic increase in gabapentinoid prescribing in recent years.

Secular Trends in Central Nervous System-Active Polypharmacy Among Serial Cross-Sections of US Adults, 2009-2020.

Background: Data comprehensively examining trends in central nervous system (CNS)-active polypharmacy are limited. The objective of this cross-sectional study was to characterize the composition of and trends in CNS-active medication use in US adults.

Methods: We included all participants ≥ 18 years old in the National Health and Nutrition Examination Study (NHANES), 2009-2020.

One Step at a Time: Improving Gait Speed Measurement in a Geriatric Medicine Clinic.

(1) Background: Mobility assessment is a key component of the assessment of an older adult as a part of the Age-Friendly Health System (AFHS) "geriatric 4Ms" framework. Several validated tools for assessing mobility and estimating fall risk in older adults are available. However, they are often under-utilized in daily practice even in specialty geriatric medicine care settings.

Medication misuse and overuse in community-dwelling persons with dementia.

Background: Persons with dementia (PWD) have high rates of polypharmacy. While previous studies have examined specific types of problematic medication use in PWD, we sought to characterize a broad spectrum of medication misuse and overuse among community-dwelling PWD.

Methods: We included community-dwelling adults aged ≥66 in the Health and Retirement Study from 2008 to 2018 linked to Medicare and classified as having dementia using a validated algorithm.

New psychotropic medication use among Medicare beneficiaries with dementia after hospital discharge.

Background: Hospitalizations among people with dementia (PWD) may precipitate behavioral changes, leading to the psychotropic medication use despite adverse outcomes and limited efficacy. We sought to determine the incidence of new psychotropic medication use among community-dwelling PWD after hospital discharge and, among new users, the proportion with prolonged use.

Methods: This was a retrospective cohort study using a 20% random sample of Medicare claims in 2017, including hospitalized PWD with traditional and Part D Medicare who were 68 years or older.

Attitudes toward deprescribing among older adults with dementia in the United States.

Background: People with dementia (PWD) take medications that may be unnecessary or harmful. This problem can be addressed through deprescribing, but it is unclear if PWD would be willing to engage in deprescribing with their providers. Our goal was to investigate attitudes toward deprescribing among PWD.

Polypharmacy among older adults with dementia compared with those without dementia in the United States.

Background/objectives: In older persons with dementia (PWD), extensive medication use is often unnecessary, discordant with goals of care, and possibly harmful. The objective of this study was to determine the prevalence and medication constituents of polypharmacy among older PWD attending outpatient visits in the United States.

Design: Cross-sectional analysis.

Potential Medicare Savings From Generic Substitution and Therapeutic Interchange of ACE Inhibitors and Angiotensin-II-Receptor Blockers.

This economic evaluation study estimates the potential Medicare savings from generic substitution and therapeutic interchange of brand-name hypertension medications.

Emotion detection deficits and changes in personality traits linked to loss of white matter integrity in primary progressive aphasia.

Non-cognitive features including personality changes are increasingly recognized in the three PPA variants (semantic-svPPA, non fluent-nfvPPA, and logopenic-lvPPA). However, differences in emotion processing among the PPA variants and its association with white matter tracts are unknown. We compared emotion detection across the three PPA variants and healthy controls (HC), and related them to white matter tract integrity and cortical degeneration.

The interface between delirium and dementia in elderly adults.

Delirium and dementia are two of the most common causes of cognitive impairment in older populations, yet their interrelation remains poorly understood. Previous studies have shown that dementia is the leading risk factor for delirium and that delirium is an independent risk factor for subsequent development of dementia. However, a major area of controversy is whether delirium is simply a marker of vulnerability to dementia, whether the effect of delirium is solely related to its precipitating factors, or whether delirium itself can cause permanent neuronal damage and lead to dementia.

Odor identification and Alzheimer disease biomarkers in clinically normal elderly.

Objectives: Our objective was to investigate cross-sectional associations between odor identification ability and imaging biomarkers of neurodegeneration and amyloid deposition in clinically normal (CN) elderly individuals, specifically testing the hypothesis that there may be an interaction between amyloid deposition and neurodegeneration in predicting odor identification dysfunction.

Methods: Data were collected on 215 CN participants from the Harvard Aging Brain Study. Measurements included the 40-item University of Pennsylvania Smell Identification Test and neuropsychological testing, hippocampal volume (HV) and entorhinal cortex (EC) thickness from MRI, and amyloid burden using Pittsburgh compound B (PiB) PET.

Comprehension of insincere communication in neurodegenerative disease: lies, sarcasm, and theory of mind.

Comprehension of insincere communication is an important aspect of social cognition requiring visual perspective taking, emotion reading, and understanding others' thoughts, opinions, and intentions. Someone who is lying intends to hide their insincerity from the listener, while a sarcastic speaker wants the listener to recognize they are speaking insincerely. We investigated whether face-to-face testing of comprehending insincere communication would effectively discriminate among neurodegenerative disease patients with different patterns of real-life social deficits.

Clinicopathological correlations in corticobasal degeneration.

Objective: To characterize cognitive and behavioral features, physical findings, and brain atrophy patterns in pathology-proven corticobasal degeneration (CBD) and corticobasal syndrome (CBS) with known histopathology.

Methods: We reviewed clinical and magnetic resonance imaging data in all patients evaluated at our center with either an autopsy diagnosis of CBD (n = 18) or clinical CBS at first presentation with known histopathology (n = 40). Atrophy patterns were compared using voxel-based morphometry.
