Associations between dual‐task walking and cognitive impairment in people attending a cognitive diagnostic clinic.
Objectives: Dual‐task walking performance is an early marker of dementia. However, there is uncertainty about which measure of the dual‐task test is a better marker.

However, there is uncertainty about which measure of the dual‐task test is a better marker. The objective of this study was to determine which dual‐task measure best differentiates between normal cognition, mild cognitive impairment (MCI) and dementia. Methods: Participants (n = 116) were aged ≥60 years attending a cognitive clinic in Melbourne, Australia. Single‐ and dual‐task gait speed were obtained using a 16 metre distance and stopwatch. The cognitive task involved reciting alternate letters of the alphabet sitting and walking. Dual‐task interference in gait and cognition was calculated as: single‐task‐dual‐task/single task × 100 and summed to obtain total interference. Multiple linear regression was used to determine differences in single and dual‐task measures between those with no cognitive impairment (n = 11), MCI (n = 54) and dementia (n = 51). Results: The mean age of the sample was 76.9 (SD 6.4) years and 48.3% (n = 56) were female. Compared to those with dementia: (a) those with MCI had a higher dual‐task letter rate and lower cognitive and total interference (all indicate better performance) (p <.05) and (b) those with no cognitive impairment had a higher single‐ and dual‐task letter rate (both indicate better performance) (p <.05). There were no differences between those with no cognitive impairment and those with MCI (all p >.05). Conclusions: In a cognitive clinic, measurement during dual‐task walking differentiated those with dementia from those with MCI or no cognitive impairment. However, differences appear to be driven by performance on the cognitive, rather than the gait task. pubtype: Academic Journal doctype: equations & formulas research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
