Motoric cognitive risk (MCR) is a syndrome that has been defined as a pre- dementia state. [1] It is characterized by a measurable slow walking speed and self-reported cognitive complaints in the absence of significant functional impairment or dementia. [1] The cognitive impairment is less than what would typically be detected on standard cognitive testing. The syndrome was first introduced by J. Verghese et al. in 2013. [1]
MCR has been shown to reliably identify individuals at high risk. [2] MCR has potential for early identification and prevention of dementia.
In the context of MCR, slow gait speed is defined as being one standard deviation below the age and sex-matched average for that population. [1] Self-reported cognitive complaints have been measured differently in various studies. [1]
