To investigate the timing and impact of new-onset dual sensory impairment on cognitive decline.
Analyzed data from two longitudinal studies
Assessed cognitive function before and after incident dual sensory impairment
Compared trajectories of cognitive decline pre- and post-DSI onset
Participants showed accelerated cognitive decline after new-onset dual sensory impairment
No significant cognitive decline was observed before the onset of dual sensory impairment
Incident DSI correlates with cognitive decline, but only after it occurs
Abstract
Participants experienced accelerated cognitive decline upon developing new-onset DSI. Incident DSI is associated with accelerated cognitive decline after, but not before, the event.
