Conclusion: a poorer concordance between tests as a function of increased cognitive impairment implies that the interpretation of these tests and the choice of co-primary-co-cognitive outcomes may depend on the degree of impairment. The recent study showed that cognitive function was significantly linked to differences between self-reported physical activity and physical activity assessed by the accelerometer. Older men with low cognitive function reported proportionally more physical activity compared to accelerometer-assessed physical activity than people with high cognitive function. Differences between accelerometer-assessed physical activity and self-reported activity may be due to difficulties in understanding a physical activity questionnaire or the inability to correctly remember past physical activity behaviour. The results were strong, as they did not change after including a large number of confusing variables like age, interviewer, and body mass index. These results indicate that cognitive function is an important factor in comparing self-reported physical activity and accelerometer. Cognitive function may be a factor explaining the differences between self-healing physical activity and acceleration activity, especially in older adults. Cognitive limitations are more common in older populations because consulting behavior is a complex cognitive task [10, 11].
Cumming & Klineberg  found that cognitively disabled older adults reproduced less accurate long-term memories of physical activity. These results were based on a comparison between physical activity questionnaires and physical activity diaries. It has been assumed that memory processes affect self-reported physical activity. Durante & Ainsworth  identified, from a cognitive psychological point of view, different stages of retrieval information that could lead to invalid data. To properly report past physical activity, participants had to remember 1) the types of activities they performed, 2) the frequency of the activity, and 3) the date of the activity . In addition, the longer and farther away the reference periods, the more difficult each stage of memory could be. Method: Baseline responses to the Alzheimer`s Disease Assessment Scale – Cognitive, Clinical Dementia Rating and Mini-Mental State Examination were obtained from two clinical trials (n = 138 and n = 351). A graphical method of conformity analysis, the difference in mean values or the Bland Altman diagram was followed by a Levene equality of variance test, corrected for multiple comparison in each sample. .
