Abstract
Early detection of dementia is very crucial to ensure treatment begins on
time, however it is difficult to choose appropriate cognitive assessment tools
because each test is designed differently and may not be tailored to the needs
of a patient. This review compares five commonly used tests the Mini-Mental
State Examination (MMSE), Rowland Universal Dementia Assessment Scale (RUDAS),
Self-Administered Gerocognitive Examination (SAGE), Alzheimer's Disease
Assessment Scale (ADAS), and Montreal Cognitive Assessment (MoCA). Each test
has different criteria's and vary in their coverage of cognitive domains. MMSE
focuses on memory and language but lacks in the evaluation of executive and
visuospatial abilities. RUDAS and SAGE focus on memory, language and visual
thinking while ADAS mainly targets memory, executive function and language. The
MoCA is most complete as it focuses on areas like attention, memory skills,
problem solving and visual skills. This review evaluates how accurate and
reliable these tools are to help doctors decide the most efficient tool for
diagnosis.
