Objective: To test the hypothesis that lower 25-hydroxyvitamin D [25(OH)D] levels are associated with a greater likelihood of cognitive impairment and risk of cognitive decline.; Methods: We measured 25(OH)D and assessed cognitive function using the Modified Mini-Mental State Examination (3MS) and Trail Making Test Part B (Trails B) in a cohort of 1,604 men enrolled […]

Background: Hypertension (HTN) is a risk factor for dementia, and animal studies suggest that centrally active angiotensin-converting enzyme (ACE) inhibitors (those that cross the blood-brain barrier) may protect against dementia beyond HTN control.; Methods: Participants in the Cardiovascular Health Study Cognition Substudy with treated HTN and no diagnosis of congestive heart failure (n = 1054; […]

Aim: It remains unknown whether antiplatelet agents have a preventive effect on cognitive decline in patients with Alzheimer’s disease (AD). We investigated the effects of cilostazol, an antiplatelet agent and cyclic adenosine monophosphate phosphodiesterase 3 inhibitor, on cognition and regional cerebral blood flow (rCBF) in elderly patients with AD and cerebrovascular disease (CVD).; Methods: A […]

Unlabelled: BACKGOUND/OBJECTIVE: To determine the level of association between uptake of the amyloid positron emission tomography (PET) imaging agent [(18)F]flutemetamol and the level of amyloid-β measured by immunohistochemical and histochemical staining in a frontal cortical region biopsy site.; Methods: Seventeen patients with probable normal pressure hydrocephalus (NPH) underwent prospective [(18)F]flutemetamol PET and subsequent frontal cortical […]
Galantamine treatment in outpatients with mild Alzheimer’s disease
Objective: To assess long-term effectiveness of galantamine in community-dwelling persons with mild Alzheimer’s disease.; Methods: Prospective open-label trial including patients with mild AD (NINCDS-ADRDA criteria) treated with galantamine for up to 36 months. Outcome parameters included ADAS-cog/11, Bayer-ADL scale (self- and caregivers’ ratings), 10-item NPI and CGI-change, safety and tolerability measures. Data are presented based […]
Vital conversations with family in the nursing home: preparation for end-stage dementia care
Family members of persons with advanced dementia may be asked to make complex treatment decisions without having adequate knowledge regarding the risks and benefits. This 6-month, prospective, randomized trial tested the effect of an intervention consisting of a face-to-face, structured conversation about end-of-life care options with family members of nursing home residents with advanced dementia. […]

Objectives: To evaluate the validity and reliability of a cognitive test battery and questionnaires administered by telephone.; Design: Observational study; 110 participants randomly assigned to receive two administrations of the same cognitive test battery 6 months apart in one of four combinations (Time 1 administration/Time 2 administration): telephone/telephone, telephone/face to face, face to face/telephone, face […]
Platelet decline as a predictor of brain injury in HIV infection

An association between platelet decline and increased risk of progression to dementia has been observed in an advanced HIV infection cohort study. This investigation evaluated the prognostic significance of platelet decline for dementia, for psychomotor slowing, and for brain injury, as quantified in vivo, in a much larger population of HIV+ men. Platelet counts and […]
