The objective of this study was to review recent literature on sensory and cognitive interactions in older adults published since 2009. After searching databases for articles on hearing, vision, and cognition, 34 relevant articles were identified and reviewed. The key findings were:
1) Studies found associations between declines in vision, hearing, or both with declines in cognition among older adults.
2) The observed sensory-cognitive associations tended to be stronger when declines were measured in more than one sensory domain and when sensory measures involved more than just threshold sensitivity.
3) Evidence continues to accumulate supporting a link between decline in sensory function and cognitive decline in older adults.
