Background and purpose: Motoric cognitive risk syndrome (MCR) is a gait-based pre-dementia syndrome associated with risk of dementia. Ascertaining subjective cognitive and motoric complaints may facilitate early and remote identification of individuals with MCR as they are reported to precede and predict objective cognitive and motoric impairments in aging. Methods: The validity of five subjective motoric complaint (SMC) questions and 10 subjective cognitive complaint (SCC) questions was examined for discriminating MCR in 538 non-demented community-dwelling adults. Backward logistic regression was used to identify questions to develop a weighted score to define subjective MCR (MCR-S). Receiver operating characteristic analysis was applied to determine the discriminative ability of MCR-S for the objective MCR (MCR-O) definition based on SCCs and objectively measured gait. Cox proportional hazard models adjusted for potential confounders were used to examine the predictive validity of MCR-S for incident dementia. Results: Five subjective complaint questions (three SCC and two SMC) were associated with MCR-O. They were combined to define an MCR-S score (range 0–7) which yielded an area under the curve of 0.89 for discriminating MCR-O from receiver operating characteristic analysis. An optimal cut-score of 2 on the MCR-S score was determined to have good sensitivity (84%) and specificity (82%) for MCR-O. Over a median follow-up of 2.5 years, 29 participants developed dementia. Both MCR-S (adjusted hazard ratio 2.39) and MCR-O at baseline (adjusted hazard ratio 3.16) predicted risk of incident dementia. Conclusions: Subjective MCR had high concordance with MCR-O and can provide a remote screening assessment for MCR-O, which can identify those at high risk for dementia.
