The Brief Memory and Executive Test (BMET) is a short neuropsychological screening tool which takes approximately 10 minutes to administer. The BMET includes tests of executive functioning, processing speed, memory and orientation, and was designed to be administered by health professionals with little experience in the administration of neuropsychological tests and instructions for administration and scoring are provided here.
Summary of BMET tests:
1. Orientation - Ten questions concerning time and place orientation and autobiographical facts, such as name and date of birth.
2. Letter-number matching - This test of processing speed requires the participant to use a key to write appropriate numbers into a serious of empty boxes arranged in a grid. The numbers are chosen by seeing a letter above each empty box and finding the corresponding letter within a key at the top of the page which has the letter underneath a designated matching number.
3. Five item repetition – This is a test of working memory and verbal learning. Five words are read aloud by the assessor and the participant repeats them back immediately (in any order).
4. Sequencing (Motor, letter, letter-number) – This is a test of executive functioning, containing three levels of difficulty, reflecting increasing executive function load. All three are presented on an A4 page of paper, are preceded by short practice items and involve pencil drawing. Motor Sequencing requires tracing over a simple line which connects up a sequence of boxes. Letter Sequencing requires joining up pseudo-randomly placed diamonds which contain letters of the alphabet, in alphabetical order, whilst ignoring empty distracter diamonds. Letter-number Sequencing requires switching between numbers and letters, for example, ‘1-A-2-B…’.
5. Five item recall - This is an episodic memory task. Participants are asked to recall the five words from the five-item repetition task.
6. Five item recognition - This is a cued episodic memory task. The five words from the five-item repetition task are displayed on a page mixed with 20 distracter words.
