Modeling trajectories and transitions: results from the New York University caregiver intervention
Background: Current research fails to capture the temporal dynamics of chronic disease in favor of cross-sectional snapshots of symptoms and outcomes.; Objective: The aim of this study was to estimate the effects of comprehensive psychosocial support on trajectories of spouse caregivers’ well-being related to the nursing home placement transition.; Method: Data from the New York […]

Treatment of Alzheimer’s disease with a cholinesterase inhibitor combined with antioxidants
A formula (formula F) was prepared to counteract oxidative stress (OS) in the brain. The formula contained the most common antioxidants and was intended to: (a) protect proteins, lipids, DNA and proteoglycans from oxidation (carnosine, coenzyme Q(10), vitamin E, vitamin C, beta-carotene, selenium, L-cysteine and ginkgo biloba); (b) reduce homocysteine (HCy) blood levels (vitamins B(6), […]

Computer-assisted system for diagnosis of Alzheimer disease using data base- independent estimation and fluorodeoxyglucose- positron-emission tomography and 3D-stereotactic surface projection
Background and Purpose: Recently, voxel-based statistical parametric images have been developed as additional diagnostic tools for AD. However these methods require the generation of a data base of healthy brain images. The purpose of this study was to produce and evaluate an automatic method using a data base-independent estimation system for the diagnosis of mild […]

CSF α-synuclein concentrations do not fluctuate over hours and are not correlated to amyloid β in humans
Reports on the value of cerebrospinal fluid (CSF) α-synuclein as a biomarker for dementia with Lewy bodies and Parkinson disease are contradicting. This may be explained by fluctuating CSF α-synuclein concentrations over time. Such fluctuations have been suggested for CSF amyloid β concentrations. Furthermore, a physiological relationship between α-synuclein and amyloid β has been suggested […]

Insulin resistance and medial prefrontal gyrus metabolism in women receiving hormone therapy
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 […]

Retrospective lifetime dietary patterns predict cognitive performance in community-dwelling older Australians
Dietary intake is a modifiable exposure that may have an impact on cognitive outcomes in older age. The long-term aetiology of cognitive decline and dementia, however, suggests that the relevance of dietary intake extends across the lifetime. In the present study, we tested whether retrospective dietary patterns from the life periods of childhood, early adulthood, […]
