Importance: Menopausal hormone therapy continues in clinical use but questions remain regarding its risks and benefits for chronic disease prevention.; Objective: To report a comprehensive, integrated overview of findings from the 2 Women’s Health Initiative (WHI) hormone therapy trials with extended postintervention follow-up.; Design, Setting, and Participants: A total of 27,347 postmenopausal women aged 50 […]
Informant-reported cognitive symptoms that predict amnestic mild cognitive impairment
Background: Differentiating amnestic mild cognitive impairment (aMCI) from normal cognition is difficult in clinical settings. Self-reported and informant-reported memory complaints occur often in both clinical groups, which then necessitates the use of a comprehensive neuropsychological examination to make a differential diagnosis. However, the ability to identify cognitive symptoms that are predictive of aMCI through informant-based […]
Slowing progression of early stages of AD with alternative therapies: a feasibility study
This pilot study identified the feasibility and efficacy of the effect of combining healing touch (HT) and body talk cortices (BTC) on the progression of Alzheimer’s disease (AD). Both HT and BTC elicit the relaxation response and support cognitive function from two different perspectives. A two-group, repeated measures design was used. Subjects (n = 22), 65 or […]
Making physical activity accessible to older adults with memory loss: a feasibility study
Purpose: For individuals with mild cognitive impairment (MCI), memory loss may prevent successful engagement in exercise, a key factor in preventing additional disability. The Resources and Activities for Life Long Independence (RALLI) program uses behavioral principles to make exercise more accessible for these individuals. Exercises are broken into small steps, sequenced, and linked with cues […]

Deep learning based imaging data completion for improved brain disease diagnosis

Ji, Shuiwang
Combining multi-modality brain data for disease diagnosis commonly leads to improved performance. A challenge in using multimodality data is that the data are commonly incomplete; namely, some modality might be missing for some subjects. In this work, we proposed a deep learning based framework for estimating multi-modality imaging data. Our method takes the form of […]
