Orientation--standard 5-10 items are not specific. One author (Hodges) suggests adding time of day as even mildly demented will show confusion of time of day esp. AM for PM
Language-- Aspects to cover in screening are fluency in conversation, and level of comprehension (oral and written). Also, naming, repetition, reading and writing. If abnormal , tests should be supplemented by additional testing.
Spatial abilities-- Draw a clock or copy Necker cube is more sensitive than the interlocking pentagons of the MMSE. (Add so is CFT).
Perception-- authors suggest testing telling time from analog clock faces.
Frontal lobe functions-- Proverbs are positive in nondemented noneducated patients. Suggests Luria's Three Hand Test. Notes localization not specific could also be subcortical. I also use F,A,S test routinely.
Psychomotor speed- easy screening test-- ask the patient to write alphabet as quickly as possible. Score shold be less than 20 seconds.
