Hypothesis
The study investigates the relationship between visual functions and cognitive performance in older adults using the LASSI-L test.
Conclusion
Contrast sensitivity is significantly associated with cognitive performance measures in older adults, indicating that visual changes may occur alongside cognitive decline.
Supporting Evidence
- Contrast sensitivity was significantly associated with LASSI-L maximum storage capacity.
- Contrast sensitivity was significantly associated with proactive semantic interference.
- Contrast sensitivity was significantly associated with failure to recover from proactive semantic interference.
- Distance visual acuity was not associated with LASSI-L measures.
Takeaway
Older people who have trouble seeing things clearly might also have trouble with their thinking skills.
Methodology
Participants underwent vision tests and the LASSI-L cognitive test, with multiple linear regressions used to analyze the data.
Participant Demographics
Participants were aged 61 to 88, with a mean age of 73.5 years, 68% female, and about 60% identified as Hispanic/Latino.
