The rate at which elderly are being diagnosed with dementia has accelerated over the recent years and it is alarming [1]. They are three times more likely to fall and over three times more likely to have severe injury compared to cognitively unimpaired elderly [2]. Consequently, recently there is an interest in the identification of biomarkers that can contribute towards, or establish, early detection and diagnosis of dementia. One of the characteristics of dementia is the inability of the patient to allocate attentional resources to concurrent tasks [1]. Consequently, towards the identification of biomarkers for the early detection of dementia, recent studies have used walking gait in conjunction with another cognitive or motor task and contrast performance to walking gait as a stand-alone task [3-5]. Typically, the temporal-spatial parameters of gait are being evaluated to identify individuals with the disease, the type of dementia and its progression.
