Dual-task performance in seniors with mild cognitive impairment and Alzheimer's disease: a longitudinal study.
BACKGROUND: Motor performance in older adults with cognitive impairment is worse under dual task conditions, increasing the risk of falls. However, there is a lack of studies that analyze this performance over time in people with different cognitive profiles. AIM: This study aimed to compare the per...

However, there is a lack of studies that analyze this performance over time in people with different cognitive profiles. AIM: This study aimed to compare the performance of an isolated task and a dual task in people with preserved cognition (PrC), with mild cognitive impairment (MCI) and Alzheimer's disease (AD). METHOD: Data were collected on two occasions (T1 and T2), thirty-two months apart. Participants (n=51) were separated between groups: PrC (n=22), MCI (n=19) and AD (n=10). They were analyzed in three situations: 1) isolated motor task - Timed up and go test (TUGT); 2) cognitive-motor test (CMT)--dialing on a phone; 3) dual task (DT). To compare the performance of the dual task between the groups, delta was calculated and the ANCOVA test was applied. RESULTS: Although the cost of the dual task was not significantly different over time in any group, we found increases in the time required to complete the TUGT (p<0.01) and TUGT-DT (p>0.01) after 32 months in the AD group and a reduction in time in the PrC and MCI groups. A greater number of steps in the TUGT-DT (p<0.01) and an increase in cadence in the TUGT (p = 0.01) and TUGT-DT (p<0.01) were also found in the AD group. CONCLUSION: We suggest that a more functional task, such as walking while typing on the phone, may be considered a more sensitive way of assessing older adults with AD. pubtype: Academic Journal doctype: equations & formulas pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
