This is how a doctor performs the test, and how a patient is graded:

1. ALTERNATING TRAIL MAKING

TEST: The patient is told to pair up five numbers and letters (1-5, A-E) in ascending order (pairing 1 with A, 2 with B, etc) while drawing connect-the-dots lines.

RESULT: The patient gets a point for every successful pair: 1-A; 2-B; 3-C; 4-D; 5-E. No lines can be crossed. The patient earns 0 if they make a mistake that is not immediately corrected.

2. VISUOCONSTRUCTIONAL SKILLS (CUBE)

TEST: Draw your own version of the cube in the space next to it.

It must be exactly the same as the one printed on the page.

RESULT: One point if it is drawn correctly (i.e. three-dimensional, all lines are drawn, no line is added, lines are relatively parallel and their length is similar – no point if any of those criteria are missing).

3. VISUOCONSTRUCTIONAL SKILLS (CLOCK)

TEST: Draw a clock, putting in all the numbers and set the time to 10 minutes past 11 o’clock.

RESULT: One point is allocated for each of the following three criteria:

Contour (ONE POINT): the clock face must be a circle with only minor distortion acceptable (i.e. slight imperfection on closing the circle).
Numbers (ONE POINT): all clock numbers must be present with no additional numbers; numbers must be in the correct order and placed in the approximate quadrants on the clock face. Roman numerals are acceptable. Numbers can be placed outside the circle contour.
Hands (ONE POINT): there must be two hands jointly indicating the correct time; the hour hand must be clearly shorter than the minute hand. Hands must be centered within the clock face with their junction close to the clock center.

A point is not assigned for a given element if any of the above-criteria are not met.

4. NAMING

TEST: Name each animal.

Lion
Rhinoceros (or rhino)
Camel (or dromedary)

RESULT: One point for each

5. MEMORY

TEST:

The doctor tells the patient that they are going to read a list of words that the patient must remember. At the end the patient has to tell them as many as they remember; it doesn’t matter what order.

The doctor then reads five words, one per second:

FACE, VELVET, CHURCH, DAISY, RED

As the patient recites the words, the doctor marks a check in the box for each word said aloud.

The patient indicates when they have recalled all they can.

The doctor reads the list a second time. At the end the patient has to recall all of them again.

As the patient recites the words, the doctor marks a check in the box for each word said aloud – including the first five again.

The patient indicates when they have recalled all they can.

At the end of the test, the doctor asks the patient to recall the five words, unprompted. This is the part of the test that is scored.

SCORING: No plus points, only minus if they get it wrong.

6. ATTENTION

TEST (NUMBERS):

Recall numbers: The doctor reads a list of five numbers at a rate of one number per second; the patient recalls them exactly as they were said:

2 1 8 5 4

Recall numbers backwards: The doctor reads three numbers at a rate of one number per second; the patient recalls them backwards:

7 4 2

SCORING: One point per sequence correctly recited.

TEST (LETTERS): The doctor reads a list of letters at a rate of one per second. Every time they say the letter ‘A’, the patient has to tap their hand:

F B A C M N A A J K L B A F A K D E A A A J A M O F A A B

SCORING: One point if there is zero errors or just one error (i.e. the patient tapped their hand on another letter just once).

TEST (MATH): The patient starts at 100, then must count down by subtracting seven every time, until the examiner tells them to stop:

SCORING: Total of three points.

No points if there are no correct subtractions
One point for just one correct subtractions
Two points for two or three correct subtractions
Three points for four or five correct subtractions

If the first subtraction is wrong, but each subsequent subtraction follows the pattern of seven, they still earn every other point. For example, they may say ’92 – 85 – 78 – 71 – 64′. While ’92’ is incorrect, all subsequent numbers are subtracted by seven, meaning they only made one mistake, and would a score of three.

7. SENTENCE REPETITION

TEST:

Step one: The examiner reads this sentence, and the patient has to repeat it exactly: ‘I only know that John is the one to help today’.

Step two: The examiner then reads another sentence, with the same instruction: ‘The cat always hid under the couch when dogs were in the room’.

SCORING: One point for each correct sentence.

Exact repetition
No synonyms substituted (i.e. it must be ‘hid’ not ‘hides’)

8. VERBAL FLUENCY

TEST: The doctor reads out a letter (F), and the patient has to think of words that starts with that letter. The aim is to reach 11 words or more in 60 seconds.

The words cannot be proper nouns, like Bob or Boston
The words cannot be the same sounding word but with different suffixes (like love, lover, loving)

SCORING: One point if they reach 11 words or more in one minute.

9. ABSTRACTION

TEST: The patient has to describe what the relationship is between certain words (i.e. an orange and a banana; a train and a bicycle; a ruler and a watch).

There is one practice trial (ORANGE AND BANANA) before two scored pairs (TRAIN AND BICYCLE; WATCH AND RULER).

SCORING: One point for each of the last two pairs.
