Liu et al reported a nomogram for evaluating a patient with features of the Motoric Cognitive Risk syndrome. This can help to predict the risk of cognitive impairment in the future. The authors are from
Parameters:
(1) mental status
(2) age in years, from 60 to 90
(3) education
(4) baseline cognition score, from 0 to 31
