“…Different tests have been proposed to evaluate cognitive function including memory, orientation, attention, reasoning and judgment, language skills, and attention [17,18,19]. Examples of such tools include the Eight-item Informant Interview to Differentiate Aging and Dementia (AD8), Annual Wellness Visit (AWV), General Practitioner Assessment of Cognition (GPCOG) and Health Risk Assessment (HRA), Memory Impairment Screen (MIS) (i.e., it is for testing verbal memory capability), Short Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Montreal Cognitive Assessment (MoCA) (i.e., it consists of a 30points scales [20] to identify subjects with MCI) [21], Addenbrooke's Cognitive Assessment (ACE) [22,23], and the Alzheimer's Disease Assessment Scale-Cognitive Subscale ADAS-Cog [24,25] (i.e., it examines attention, orientation, memory, language, visual perception, and visuospatial skills), the test can detect cognitive impairment that is related to AD and fronto-temporal dementia. Other examples include the Cambridge Assessment of Memory and Cognition, the Mini-Mental State Examination (MMSE) (it can assess impairments related to five cognitive functions such as orientation, attention, memory, language and visual-spatial skills by just asking subjects 11 questions [17]) test (its sensitivity is around 0.79, while its specificity is around 0.95) [26], the Saint Louis University Mental Status (SLUMS) (i.e., it encompasses a 30-point screening questionnaire to examine not only executive function but also orientation, memory, and attention) [27] and Cognitive Disorders Examination (Codex) (an ML-based assessment tool that combines a decision tree with the MMSE test and the clock drawing test to diagnose dementia.…”
