Publication: Passive Measures of Physical Activity and Cadence as Early Indicators of Cognitive Impairment: Observational Study

Authors: Huitong Ding, Stefaniya Brown, David R Paquette, Taylor A Orwig, Nicole Spartano, Honghuang Lin Abstract Background: Emerging research shows regular physical activity reduces cognitive decline risk, but most studies rely on self-reported measures, which are limited by recall bias, subjectivity, and a lack of continuous monitoring capability. Objective: This study aimed to explore passive physical activity measures as early indicators of cognitive impairment by examining their association with cognitive impairment incidence and neuropsychological (NP) test performance. Methods: We included participants from the Framingham Heart Study (FHS), a community-based cohort with longitudinal cognitive impairment surveillance. Participants wore an Actical accelerometer for at least 3 days, excluding bathing. Thirty physical activity measures were grouped into intensity-specific durations, step and cadence summaries, and peak cadence. Cox proportional hazard models were applied to assess their associations with incident…

Oral Presentation: The Impact of Light Exposure on Sleep: A Pilot Study

This is part of the monthly MassAITC webinar series. Abstract: Light exposure is the primary regulator of human circadian rhythms, influencing many aspects of our physiology and behavior, including sleep, alertness, and mood, as well as many neuroendocrine and cognitive functions. While we have evolved experiencing “bright days and dark nights,” most of us now experience significantly darker days and brighter nights than our pre-modern ancestors, likely resulting in widespread circadian disruption. And as we age, the relationship between light exposure, circadian rhythms, and sleep can be further compromised both through normal aging (e.g., less light reaching the retina due to clouding of the lens) and age-related risk factors, such as Alzheimer’s Disease (AD), which is known to damage the brain’s master clock. This webinar will review the current science related to light exposure, circadian…

Continuation of VR technology development focused on the caregiver side of the dyad. Public Health Relevance Statement: The VR-CARES project is an innovative, collaborative effort that invites home health dementia caregivers into the design process of a virtual reality platform seeking to mitigate their work-related burden and social isolation by cultivating a virtual community of support. The co-created, caregiver-specific VR platform will serve as a safe, communal space where caregivers can remotely connect with their peers, share fun experiences together, access support, learn self-care and build resilience within a supportive virtual network to enhance their social and mental health and job satisfaction. Central to VR-CARES is the principle of user-led innovation, ensuring that the technology not only serves but is informed and successfully adopted by the very individuals it intends to benefit, an important standard…
