Mini-Mental State Examination (MMSE): The most used today, has a sensitivity of 75% - 92% and specificity of 81% - 91%, allowing assessment of many different cognitive functions. These are: Orientation, computation, memory, attention, language, and visual reproduction. It takes about 7 minutes to take the MMSE test, with a total score of 30. A score below 24 indicates dementia. However, this method has the limitation that it is not sensitive to early-stage dementia, which can be affected by the patient's age, education, language, reduced mobility and visual acuity; Montreal Cognitive Assessment (MoCA): A test to help detect memory decline in the elderly.
