Tests by domain Hodges

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.
