Treatment outcomes of a crisis intervention program for dementia with severe psychiatric complications: the Kansas bridge project

Purpose: Although declines in memory and attention are hallmark symptoms of Alzheimer’s disease (AD), noncognitive symptoms are prevalent. Over 80% of individuals will experience neuropsychiatric symptoms, which complicates symptom profiles. Research indicates a community-integrated response to dementia crisis can reduce negative consequences attributed to crisis including increased caregiver burden, increased health care costs, and premature […]

Accelerated cell aging in female APOE-ε4 carriers: implications for hormone therapy use

Apolipoprotein-ε4 (APOE-ε4) is a major genetic risk factor for cognitive decline, Alzheimer’s disease (AD) and early mortality. An accelerated rate of biological aging could contribute to this increased risk. Here, we determined whether APOE-ε4 status impacts leukocyte telomere length (TL) and the rate of cellular senescence in healthy mid-life women and, further, whether hormone replacement […]

Nursing homes and end-of-life care in Japan

Objectives: To describe end-of-life care in Japanese nursing homes by comparing facility and characteristics of residents dying in nursing homes with those who had been transferred and had died in hospitals, and by comparing the quality of end-of-life care with hospitals and with their respective counterparts in the United States.; Setting: National sample of 653 […]

Safety, tolerability, and efficacy of PBT2 in Huntington’s disease: A phase 2, randomised, double-blind, placebo-controlled trial

Background: PBT2 is a metal protein-attenuating compound that might reduce metal-induced aggregation of mutant huntingtin and has prolonged survival in a mouse model of Huntington’s disease. We aimed to assess the safety, tolerability, and efficacy of PBT2 in patients with Huntington’s disease. Methods: In this 26-week, randomised, double-blind, placebo-controlled trial, adults (≥ 25 years old) […]

Impact of TimeSlips creative expression program on behavioral symptoms and psychotropic medication use in persons with dementia in long-term care: a cluster-randomized pilot study

Objectives: To evaluate whether involvement in TimeSlips, a creative storytelling program, reduced mood and behavioral symptoms as well as psychotropic medication use in persons with dementia.; Methods: A cluster-randomized pilot study compared two discrete dementia care units in one nursing home. The control cohort (N = 10) received standard-of-care activity programming, and the intervention cohort (N = […]

Outcomes from the Resources for Enhancing Alzheimer’s Caregiver Health (REACH) program for bereaved caregivers

Although preventive efforts for bereaved individuals have not been shown to be particularly effective in past studies, it has been suggested that intervention effects might be underestimated due to methodological issues such as short follow-up assessments. Thus, the present study aimed to assess the efficacy (as whole intervention packages and as component parts) of the […]

Personality as a moderator of cognitive stimulation in older adults at high risk for cognitive decline

This exploratory study examined the moderating effects of personality traits on cognitive function following a cognitively stimulating individualized activity intervention delivered to individuals at high risk for cognitive decline: those with delirium superimposed on dementia. Data were taken from an ongoing randomized clinical trial with the addition of a personality measure. The results for 71 […]

Time until incident dementia among Medicare beneficiaries using centrally acting or non-centrally acting ACE inhibitors

Background: Centrally active (CA) angiotensin-converting enzyme inhibitors (ACEIs) are able to cross the blood–brain barrier. Small observational studies and mouse models suggest that use of CA versus non-CA ACEIs is associated with a reduced incidence of Alzheimer’s disease and related dementias (ADRD).; Objective: The aim of this research was to assess the effect of CA […]

Subjective stressors moderate effectiveness of a multi-component, multi-site intervention on caregiver depression and burden

Objectives: The present study assessed whether caregiving contextual factors moderated outcomes of a caregiver intervention.; Methods: Extant data from the Resources for Enhancing Alzheimer’s Caregiver Health (REACH) II study, a randomized-control trial of a multi-component, multi-site intervention for dementia caregivers was utilized. 498 caregivers {83.1% women; mean [standard deviation (SD)] age = 60.3 (13.1)}, and their care […]

Antihypertensive therapy and cerebral hemodynamics in executive mild cognitive impairment: results of a pilot randomized clinical trial

Objectives: To compare the effects of three antihypertensive medications on cerebral hemodynamic and cognitive function in hypertensive individuals with executive dysfunction.; Design: Double-blind randomized clinical trial.; Setting: Community.; Participants: Fifty-three individuals aged 60 and older with hypertension and executive dysfunction.; Intervention: Lisinopril, candesartan, or hydrochlorothiazide for 1 year.; Measurements: Cerebral blood flow velocity (BFV; transcranial […]
