There has been increasing interest in the influence of diet on cognition in the elderly. This study examined the cross-sectional association between dietary patterns and cognition in a sample of 249 people aged 65-90 years with mild cognitive impairment (MCI). Two dietary patterns; whole and processed food; were identified using factor analysis from a 107-item; […]
DHEA and cognition in HIV-positive patients with non-major depression
Background: Dihydroepiandrosterone (DHEA) has been investigated for its potential role in improving cognition in a number of patient populations. Treatment options are limited for HIV-associated neurocognitive disorders.; Objective: The authors tested the effect of DHEA administration on the cognitive functioning of HIV-positive subjects with non-major depression.; Method: The neuropsychological testing data for 60 HIV-positive patients […]

Background and Purpose: High plasma total homocysteine (tHcy) has been associated with cognitive impairment but lowering tHcy with B-vitamins has produced equivocal results. We aimed to determine whether B-vitamin supplementation would reduce tHcy and the incidence of new cognitive impairment among individuals with stroke or transient ischemic attack≥6 months previously.; Methods: A total of 8164 […]

Objectives: Active and passive immunization strategies have been suggested as possible options for the treatment of Alzheimer disease (AD). LY2062430 (solanezumab) is a humanized monoclonal antibody being studied as a putative disease-modifying treatment of AD.; Methods: Patients with mild to moderate AD were screened and selected for inclusion. Initial screening was performed for 54 subjects, […]

Objective: Depression is common in Alzheimer disease (AD), and antidepressants are commonly used for its treatment, however, evidence for antidepressant efficacy in this population is lacking. The authors conducted a multicenter, randomized, placebo-controlled trial titled “Depression in Alzheimer’s Disease-2” to assess the efficacy and tolerability of sertraline for depression in AD.; Methods: One hundred thirty-one […]
Alzheimer’s Disease Anti-inflammatory Prevention Trial: design, methods, and baseline results
Background: The Alzheimer’s Disease Anti-inflammatory Prevention Trial (ADAPT) was designed to address whether non-steroidal anti-inflammatory drugs (NSAIDs) can prevent or delay the onset of Alzheimer’s disease (AD).; Methods: ADAPT was a randomized, double-placebo-controlled, multicenter chemoprevention trial conducted at six U.S. dementia research clinics. At entry, participants were required to test “normal” on a battery of […]
