Mibampator (LY451395) randomized clinical trial for agitation/aggression in Alzheimer’s disease

Background: Mibampator, an amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptor potentiator, was evaluated for treatment of agitation and aggression (A/A) in Alzheimer’s disease (AD).; Methods: Outpatients (n = 132) with probable AD and A/A randomized to 12 weeks of double-blind treatment with 3-mg po mibampator or placebo were assessed using the 4-domain A/A subscale of the Neuropsychiatric Inventory […]

Neuroimaging predictors of brain amyloidosis in mild cognitive impairment

Objective: To identify a neuroimaging signature predictive of brain amyloidosis as a screening tool to identify individuals with mild cognitive impairment (MCI) that are most likely to have high levels of brain amyloidosis or to be amyloid-free.; Methods: The prediction model cohort included 62 MCI subjects screened with structural magnetic resonance imaging (MRI) and (11) […]

Development and validation of the mortality risk for trauma comorbidity index

Objective: The aim of this study was to develop and validate a comorbidity index to predict the risk of mortality associated with chronic health conditions following a traumatic injury.; Summary Background Data: Currently available comorbidity adjustment tools do not account for certain chronic conditions, which may influence outcome following traumatic injury or they have not […]

Staff training in assisted living: evaluating treatment fidelity

Objectives: To investigate a protocol for identifying and evaluating treatment fidelity in Staff Training in Assisted-living Residences (STAR), a structured but flexible program to train direct care staff to improve care of residents with dementia.; Design: Multisite feasibility trial.; Setting: Assisted living facilities (ALFs).; Participants: Forty-four direct care staff and 36 leadership staff.; Intervention: STAR […]

Decision-making and outcomes of feeding tube insertion: a five-state study

Objectives: To examine family member’s perceptions of decision-making and outcomes of feeding tubes.; Design: Mortality follow-back survey. Sample weights were used to account for oversampling and survey design. A multivariate model examined the association between feeding tube use and overall quality of care rating regarding the last week of life.; Setting: Nursing homes, hospitals, and […]

Infection hospitalization increases risk of dementia in the elderly

Objectives: Severe infections, often requiring ICU admission, have been associated with persistent cognitive dysfunction. Less severe infections are more common and whether they are associated with an increased risk of dementia is unclear. We determined the association of pneumonia hospitalization with risk of dementia in well-functioning older adults.; Design: Secondary analysis of a randomized multicenter […]

Testosterone effect on brain metabolism in elderly patients with Alzheimer’s disease: comparing two cases at different disease stages

Objective: To describe the effect of testosterone replacement therapy (TRT) on the brain activity of two demented, hypogonadal male patients with early and late-stage Alzheimer’s disease (AD), respectively.; Methods: We describe the clinical and positron emission tomography (PET) findings for two individuals, one with early stage and the other with late-stage Alzheimer’s disease, before and […]

Association of depression with accelerated cognitive decline among patients with type 2 diabetes in the ACCORD-MIND trial

Importance: Depression has been identified as a risk factor for dementia among patients with type 2 diabetes mellitus but the cognitive domains and patient groups most affected have not been identified.; Objective: To determine whether comorbid depression in patients with type 2 diabetes accelerates cognitive decline.; Design: A 40-month cohort study of participants in the […]

Evaluation of a home-based exercise program in the treatment of Alzheimer’s disease: the Maximizing Independence in Dementia (MIND) study

Objective: To determine the feasibility and efficacy of a home-based exercise intervention program to improve the functional performance of patients with Alzheimer’s Disease (AD).; Methods: Twenty-seven home-dwelling patients with AD were randomized to either an exercise intervention program delivered by their caregivers or a home safety assessment control. Measures of functional performance (primary), cognition, neuropsychiatric […]

Change in hippocampal volume on magnetic resonance imaging and cognitive decline among older depressed and nondepressed subjects in the neurocognitive outcomes of depression in the elderly study

Introduction: previous studies have linked hippocampal volume change and cognitive decline in older adults with dementia. The authors examined hippocampal volume change and cognitive change in older nondemented adults with and without major depression.; Methods: the sample consisted of 90 depressed individuals and 72 healthy, nondepressed individuals aged 60 years and older who completed at […]
