Falls continue to be a major cause of injury and loss of independence in older people. Therefore, screening for fall risk is an important part of geriatric care. We previously identified that there is a cumulative effect on fall risk if people suffer from both poorer physical and cognitive function (https://www.ncbi.nlm.nih.gov/pubmed/23410920). The current study built further on these findings by only using clinical measures, which are quick and easy to administer (without the need of a qualified health professional) to make them feasible in a clinical setting. Therefore, we searched for a measure that incorporated both gait and cognition and was quick and easy to administer.
We used the Motoric Cognitive Risk (MCR) syndrome – developed by Prof Joe Verghese (Albert Einstein College of Medicine, USA) – which is characterised by both slow gait and presence of a subjective cognitive complaint, and therefore ideal for our purposes.
Our study aimed to examine if MCR increased the risk of falls and if the diagnosis of the combined MCR was a stronger risk factor for falls than its components (i.e. slow gait or cognitive complaint). Using data from five longitudinal population-based studies (n=6204), we found that 45% of participants reported a cognitive complaint, 13.8% had slow gait, 7.5% had a diagnosis of MCR, and 33.9% reported any fall (see Figure for individual study results). MCR was associated with a 44% increase of falls in the pooled analysis of all studies. This increased risk of falls of the combined MCR was higher than for gait speed (30%) or subjective cognitive complaints (25%) alone.

The simplicity and low cost of MCR makes this an attractive falls-risk screening tool for the busy clinician. People with MCR should then proceed to a more thorough multifactorial falls assessment, to understand the cause of the slow gait (e.g. balance assessment) and poor cognitive function (e.g. neuropsychological assessment), and guide a tailored intervention program.
