Cognitive effects of quetiapine in a patient with dementia with Lewy bodies
A recent large-scale randomized controlled clinical trial, the Clinical Antipsychotic Trials of Intervention Effectiveness-Alzheimer’s Disease study, found a significant worsening of cognitive functioning in a sample of patients with Alzheimer’s disease. To date there have been no equally powered studies examining the cognitive effects of atypical antipsychotics in patients with dementia with Lewy bodies, the […]
Application of immunosignatures to the assessment of Alzheimer’s disease
Objective: Accurate assessment of Alzheimer’s disease (AD), both presymptomatically and at different disease stages, will become increasingly important with the expanding elderly population. There are a number of indications that the immune system is engaged in AD. Here we explore the ability of an antibody-profiling technology to characterize AD and screen for peptides that may […]
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. […]

Compared with in-person assessment methods, telephone screening for dementia and other cognitive syndromes may improve efficiency of large population studies or prevention trials. We used data from the Alzheimer’s Disease Anti-Inflammatory Prevention Trial to compare performance of a four-test Telephone Assessment Battery (TAB) that included the Telephone Interview for Cognitive Status (TICS) to that of […]
Insulin resistance and medial prefrontal gyrus metabolism in women receiving hormone therapy
Rasgon, Natalie L.,
Kenna, Heather A.,
Wroolie, Tonita E.,
Williams, Katherine E.,
DeMuth, Bevin N.,
Silverman, Daniel H. S.
Insulin resistance (IR) is a putative risk factor for cognitive decline and dementia, and has been shown to impede neuronal glucose metabolism in animal models. This post hoc study focused on metabolic changes in the medial prefrontal region, a brain region exhibiting decline years before documented cognitive changes, relative to high or low IR status […]
Prospective randomized trial to assess effects of continuing hormone therapy on cerebral function in postmenopausal women at risk for dementia
Rasgon, Natalie L.,
Geist, Cheri L.,
Kenna, Heather A.,
Wroolie, Tonita E.,
Williams, Katherine E.,
Silverman, Daniel H. S.
The objective of this study was to examine the effects of estrogen-based hormone therapy (HT) on regional cerebral metabolism in postmenopausal women (mean age = 58, SD = 5) at risk for development of dementia. The prospective clinical trial design included pre- and post-intervention neuroimaging of women randomized to continue (HT+) or discontinue (HT2) therapy […]

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

Visscher, Barbara R.,
Becker, James T.
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 […]
Comparison of the memory performance index with standard neuropsychological measures of cognition
The Mild Cognitive Impairment Screen (MCIS) is a computer-based cognitive assessment designed for clinical and research use in detecting amnestic mild cognitive impairment (aMCI). Performance on the MCIS is reported as the Memory Performance Index (MPI). However, the comparability between the MPI and traditional neuropsychological tests in detecting aMCI, and in differentiating it from Alzheimer’s […]
