Three Cardinal Lessons from ADAPT - 10 Years on.

The Alzheimer's Disease Anti-inflammatory Prevention Trial was a placebo-controlled three-arm pharmaco-prevention trial of the non-steroidal anti-inflammatory drugs naproxen sodium and celecoxib for prevention of incident Alzheimer's disease (AD) dementia in older (aged 70 and over) adults. Although subjects were at increased risk of symptoms because of a firstdegree family history, they were meant to be cognitively healthy at enrollment. ADAPT encountered several problems that resulted in the termination of its treatments after only two years on average.

An open science resource for establishing reliability and reproducibility in functional connectomics.

Efforts to identify meaningful functional imaging-based biomarkers are limited by the ability to reliably characterize inter-individual differences in human brain function. Although a growing number of connectomics-based measures are reported to have moderate to high test-retest reliability, the variability in data acquisition, experimental designs, and analytic methods precludes the ability to generalize results. The Consortium for Reliability and Reproducibility (CoRR) is working to address this challenge and establish test-retest reliability as a minimum standard for methods development in functional connectomics.

Extended results of the Alzheimer's disease anti-inflammatory prevention trial.

Background: Epidemiologic evidence suggests that nonsteroidal anti-inflammatory drugs (NSAIDs) delay onset of Alzheimer's dementia (AD), but randomized trials show no benefit from NSAIDs in patients with symptomatic AD. The Alzheimer's Disease Anti-inflammatory Prevention Trial (ADAPT) randomized 2,528 elderly persons to naproxen or celecoxib versus placebo for 2 years (standard deviation = 11 months) before treatments were terminated. During the treatment interval, 32 cases of AD revealed increased rates in both NSAID-assigned groups.
