Abstract:
Objective: To determine the prevalence of cognitive (memory or confusion) complaints in older adults with visual impairment (VI). Method: We assessed the relationship between VI (corrected visual acuity [VA] < 20/40) and self-reported confusion or problems with memory among participants aged 60 years to 85 years in the 1999-2006 cycles of National Health and Nutrition Examination Survey (n = 5,795). Prevalence estimates of cognitive complaints were calculated using Current Population Surveys. Results: Memory/confusion complaints were reported in 22% of the VI group and 11% of the no VI group (p < .001). In individuals aged ≥ 80 years, 30% of those with VI reported cognitive complaints, as compared with 19% with no VI (p = .003). In fully adjusted models, individuals with VI were more likely (OR = 1.3, p = .049) to report cognitive complaints as compared with those without VI. Conclusion: Subjective reports of memory or confusion are highly prevalent in older individuals with VI.

Long-Term Memory
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
