Twelve cognitive screening tools were examined across 21 studies, the majority of which included the Mini-Mental State Examination (MMSE). MMSE pooled sensitivity = 0.73 (95% CI 0.57–0.90) and pooled specificity = 0.83 (95% CI 0.75—0.90). Pooled analysis of other screening instruments was not completed due to high heterogeneity of included studies. However, overall findings revealed that the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), the Ascertain Dementia 8-item (AD8) and the General Practitioner Assessment of Cognition (GPCOG) were equal to or had better diagnostic accuracy (i.e., sensitivity and specificity) compared to the Mini-Mental State Examination (MMSE).
