Cognition and gait in older people
Cohen JA, Verghese J, Zwerling JL.. Maturitas, 2016-05-10
Topic: Risk, prevention and care in population studies
Cognitive difficulties and gait abnormalities both increase with age. We review normal and pathologic changes in both gait and cognition in older adults. Gait performance in older individuals is linked to specific cognitive changes, in particular in executive function. Structural and functional assays highlight the shared anatomic control of cognitive and gait function, mostly in the prefrontal cortices. Cognitive impairment can be used to predict incident gait difficulties. Changes in gait, especially decreased gait velocity, may be a harbinger of impending cognitive decline. The combination of slow gait and cognitive complaints (the Motoric Cognitive Risk syndrome) is a powerful new clinical tool to identify those at high risk of developing dementia and therefore may be used to target interventions. Evidence is limited, but cognitive training and targeted physical activity may be useful to mitigate or prevent gait and cognitive decline with age.

How this study scored 36/100
Published in a peer-reviewed journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 21 of the 58 points we could judge it on, which is 36 out of 100.
