Mid-trial informant replacement (IR) has been found to impact academic trial results. We hypothesized that a similar impact would be observed in industry-sponsored trials.

This likely is due to individual differences in the systemic physiological response to exercise. However, the acute effects of exercise on brain metabolism and biomarker responses are not well characterized in older adults or cognitively impaired individuals.

Background: Approximately 10% of people living with Alzheimer's dementia (PWD) experience depression, yet behavioral interventions remain scarce. We developed an innovative depression intervention, Caregiver-Provided Life Review (C-PLR) based on life review therapy. The purposes of this study were to evaluate the feasibility of training family caregivers in life review skills and evaluate the impact on depressive symptoms.
