Following these tests participants are randomized to a home-based walking program or health education for 6 months. Participants are given a fitness tracker and gets ongoing telephone coaching during the 6 months. After 6 months the tests are repeated.

The Effects of Successful OSA Treatment on Memory and AD Biomarkers in Older Adults Study

The prevalence of Alzheimer disease (AD) is high and projected to increase. While there are multiple risk factors for AD, epidemiological data suggests that ~15% of AD risk may be attributed to sleep problems. Obstructive sleep apnea (OSA) is common among the elderly (30-55%), and the investigators have shown that cognitively normal older women with OSA have nearly double the risk of developing mild cognitive impairment (MCI) or dementia over 5 years. Further, the investigators have shown that in normal elderly, OSA predicts longitudinal increases in AD biomarkers. Our preliminary data also show that after positive airway pressure (PAP) withdrawal, OSA patients treated with PAP experienced significant overnight increases in plasma neurofilament light (NfL), a marker of neural injury. The present study is designed to overcome challenges identified in previous trials of treatment of OSA to slow cognitive decline and progression to AD. First, the most effective treatment for OSA, PAP therapy, has poor adherence (typically only 50% are adequately treated). Other common therapies include oral appliance therapy (OAT) which tends to be better tolerated but less effective. The investigators have piloted and propose for this study a rapid multimodal therapy initiation (RMMT) which ensures subjects will have effective therapy for their OSA that reduces OSA severity to AHI4%<10/hour and AHI3A (AKA pRDI) < 20/hour within 4 months. Second, most prior OSA treatment trials have focused primarily on symptomatic older adults (e.g. patients with MCI recruited from memory clinics), whereas early intervention in pre-symptomatic individuals may have stronger impact in preventing progression to AD. The investigators propose to enroll cognitively normal adults with newly diagnosed moderate-severe OSA (AHI4% >20/hour or AHI3A > 40/hour). Finally, selection of cognitive outcomes most responsive to OSA therapy has proved challenging. The Effects of Successful OSA TreatmENT on Memory and AD BIomarkers in Older AduLts (ESSENTIAL) study is a 5-year, multicenter randomized open-label trial that will screen 400 cognitively normal older adults (MoCA≥24, Clinical Dementia Rating [CDR]=0), ages 55-75, recruited from well-established sleep clinics at 4 academic medical centers, with newly diagnosed moderate-severe OSA (AHI4% >20/hour or AHI3A > 40/hour). An expected 200 OSA patients will be then randomized to one of two groups: i) a 3-month OSA treatment by any combination of PAP, OAT, and positional therapy that results in an "effective" AHI4%< 10/hour and AHI3A<20/hour (see below); ii) a waitlist control group to receive treatment at the conclusion of the 3-month intervention period. Both groups will continue follow-up for 24 months on stable therapy to determine if sustained improvements in sleep are associated with improvement in cognitive function and AD biomarkers. Both arms will include PSG and actigraphy, sleep-dependent memory and other cognitive evaluations, and blood draws at baseline, 3 and 24 months, with cognitive evaluation only at 12 months. Structural brain MRI will be performed at baseline. Because the investigators anticipate that 150 of 200 subjects will be well treated at 24 months, and 50 will not be, the investigators will additionally recruit ~50 subjects (on average 13 subjects per clinical site) with the same inclusion criteria who refuse treatment. These 50 subjects will perform baseline (blood draw and cognitive evaluations), 12-month (cognitive evaluation only), and 24-month (blood draw and cognitive evaluations) visits, allowing for a 24-month comparison of ~150 subjects with adequate treatment over 24 months to 100 subjects with inadequate treatment over 24 months. Our aims are: 1) To compare 3-month change in plasma AD biomarkers (NfL, p-tau, Aβ) in those randomized to OSA treatment and wait-list control groups (via both intention-to-treat and per-protocol analyses); 2) To test differences at 3 months in sleep-dependent declarative memory and cognitive scores (PACC and sub-domains) between the OSA treatment and wait-list control groups (via both intention-to-treat and per-protocol analyses); 3) To compare 24-month changes in AD biomarkers (NfL, p-tau, Aβ) and cognition in all successfully treated subjects and untreated controls.

Eye Movement Rehabilitation in Low Vision Patients

Approximately 217 million people worldwide currently suffer from low vision, defined as mild to severe visual impairment with visual acuity between 0.5 and 1.3 logMAR2. The prevalence of low vision increases with age and may affect 7.6 million Americans by 20503. People with low vision experience significant problems across a broad range of activities of daily living, elevated levels of depression and increased mortality. The aim of the proposed project is to help people with low vision to lead more independent lives through the development of improved rehabilitation methods. To achieve this goal, this proposal brings together scientists and clinicians from Northeastern University, New England College of Optometry and the Lighthouse Guild. In many cases, low vision causes central vision loss (CVL), forcing the patient use low resolution eccentric retina for visually-guided behavior. People with CVL can learn to attend to a specific area of eccentric retina which acts as substitute for the diseased fovea known as a Preferred Retinal Locus (PRL). Increased variability in fixation patterns and eye movements with a PRL is associated with a broad range of functional deficits. There are currently no standardized methods to select, quantify or train binocular attention and eye movement control with a PRL. Therefore, this proposal aims to develop and evaluate evidence-based methods to improve oculomotor control and visual function for people who use a PRL for visually-guided behavior. In preliminary studies, the investigators show that real-time visual feedback helps people with CVL to improve oculomotor control with a PRL. Feedback consists of an eye tracker-controlled gaze-contingent ring centered on the retinal location of a binocular PRL, while the observer moves their eyes to keep this ring centered on a computer-controlled target. In this proposal, the investigators extend these rehabilitation methods to help patients with CVL to select and use a PRL for static and moving targets. The investigators include methods that improve awareness of the boundary of a pathological scotoma and methods that leverage the known coupling between eye and hand coordination. The use of a PRL will be assessed with eye movement and psychophysical metrics. Oculomotor control will be assessed for fixation, smooth pursuit and saccadic eye movements; and visual function will be quantified with visual acuity, contrast sensitivity, reading performance and questionnaires in the following Specific Aims: Aim 1) Eccentric Fixation The investigators propose to examine the use of real-time visual feedback for control of a PRL for fixation. The investigators examine how PRL training is retained over time and transfers to other untrained locations, which may be required to perform different tasks, or following disease progression. The investigators will examine the relationship between PRL location, fixation stability and visual function. Aim 2) Smooth Pursuit Eye Movements Objects in the real world and on television move around and may require smooth pursuit eye movements for sustained viewing over time. The investigators propose to use real-time visual feedback to examine how smooth pursuit with a PRL can benefit from training and how visual function varies with smooth pursuit accuracy and precision. Aim 3) Saccadic Eye Movements Normally-sighted observers move their eyes 2-3 times per second to bring items of interest onto the fovea for high resolution inspection. These saccadic eye movements must be remapped from the diseased fovea to the PRL for people with CVL. The investigators will use real-time visual feedback to examine how saccadic eye movements with a PRL can benefit from training and how visual function varies with saccade accuracy and precision. Aim 4) Scotoma Boundary Awareness Owing to perceptual filling in, many people with CVL are not aware of the locations or boundaries of their blind spots, which can impede the selection of and reference to a PRL. The investigators propose to provide real-time visual cues to facilitate awareness of the boundary of binocular pathological scotomas and combine this information with feedback to improve PRL training and visual function with a PRL. Aim 5) Hand-Eye Coordination There is a close sensory and motor coupling between the visual system and hand movement system. This linkage has been associated with perceptual improvements and increases in the accuracy of oculomotor control around the locations of the hands. The investigators propose to leverage this sensorimotor integration to study PRL training and use with meta-guidance. The investigators will quantify whether PRL control and visual function can be facilitated by meta-guidance with the observer's own hands. Overall Aims The overall goal of this minimally invasive proposal is to provide evidence-based methods to help people with low vision to maximize their residual visual function and to help them to live more independently, thereby improving quality of life and minimizing the economic, health and social burdens of visual impairment.

Lay-Delivered Behavioral Activation in Senior Centers

This Collaborative R01 application (UW, Cornell, USF) proposes to conduct an effectiveness trial of lay-delivered Behavioral Activation ("Do More, Feel Better"; DMFB), in comparison to MSW-delivered Behavioral Activation (MSW BA), for depressed (PHQ-9>10 and Ham-D>14) older (60+) senior center clients. The primary aim tests the effectiveness of DMFB, in comparison to MSW BA, on increasing overall activity level (target) and reducing depression symptoms. The investigators will test whether increased activity level predicts greater reduction in depression severity and whether increased activity's impact on depression is non-inferior across conditions. Secondarily, the investigators will test hypotheses associated with overall functioning, satisfaction with treatment, and client-level moderators. Lastly the investigators will explore longer-term client outcomes, delivery cost, and preparing for sustainability by exploring client, provider, and center factors related to intervention fidelity.
