-MoCA and RUDAS are cognitive screening tools that guide dementia diagnoses

-RUDAS is suggested to be better suited in diverse settings

-The diagnostic performance of the RUDAS compared to the MoCA is unclear

-Prospective Registry of Persons with Memory Symptoms (n=1,370)

-Patients with cognitive complaints referred to Cognitive Neurosciences Clinics in Calgary, Canada

-Full Cohort: patients that had MoCA and/or RUDAS scores were compared to the attending physicians’ working diagnosis

-Subgroup: patients that had both MoCA and RUDAS scores were compared to a gold-standard, MoCA/RUDAS-blinded, physician-adjudicated diagnosis

-Calculated sensitivity, specificity, predictive values, accuracy, and area-under-the-curve (AUC)

-Quantile regression to examine how scores varied by sociocultural factors.

-MoCA and RUDAS have similar accuracy and AUC to screen for dementia

-Full cohort: MoCA had a higher sensitivity while RUDAS had a higher specificity

-Subgroup: no significant differences between MoCA and RUDAS

-Future studies should consider using a blinded “gold standard”

-RUDAS is less influenced by language
