Introduction: With the significant increase in life expectancy, more and more people who develop dementia are recorded, which has led to a greater need to find possible protective factors. As age progresses, the ability of a person to perform two tasks at once decreases. This review explores the effect of dual-task activities on walking in people with Alzheimer’s disease (AD) and mild cognitive impairment (MCI).

Methods:In order to search for the appropriate literature, the three-stage search technique was used: a) design, b) implementation and c) evaluation. The ion criteria of the studies were: a) published between 2009 and 2020, b) investigating the effect of dual-task activities on elderly people with MCIAD during walking, c) written in GreekEnglish. The search was conducted between November and December 2020.

Results:During the bibliographic search, 2108 results were obtained. Following the removal of duplicates and the exclusion of surveys that did not meet the criteria, 18 articles were ed for this review.

Conclusions: Several studies show a significant decrease in walking speed in people with AD and MCI when walking in a dual-task condition. In addition, changes are observed in other gait parameters, if walking is combined with some cognitive task, which can be a possible risk factor of falling. In conclusion, gait tests in combination with cognitive task could be another important diagnostic tool in the field of dementia.
