General Practitioner Assessment of Cognition (GPCOG) Score

This PatientPlus article is written for healthcare professionals so the language may be more technical than the condition leaflets. You may find the abbreviations list helpful.

This test was designed as a GP screening tool for dementia.1 See related article Screening for Cognitive Impairment.

There are two components: a cognitive assessment conducted with the patient, and an informant questionnaire (only considered necessary if the results of the cognitive section are equivocal, i.e. score 5-8 inclusive).

Results >8 or < 5 on the GPCOG patient section were assumed to be cognitively intact or impaired, respectively. For patients requiring a informant questionnaire, scores of 3 or less out of 6 in this section indicates cognitive impairment.2

General Practitioner Assessment of Cognition (GPCOG)
GPCOG Patient Examination
Unless specified, each question should only be asked once.
Name and address for subsequent recall
"I am going to give you a name and address. After I have said it, I want you to repeat it. Remember this name and address because I am going to ask you to tell it to me again in a few minutes: John Brown, 42 West Street, Kensington"

(Allow a maximum of 4 attempts but do not score yet)
Time Orientation
What is the date? (accept exact only)
Clock Drawing (visuospatial functioning) use a paper with a printed circle.
Please mark in all the numbers to indicate the hours of a clock (correct spacing required).
For a correct response (above), the numbers 12, 3, 6, and 9 should be in the correct quadrants of the circle
and the other numbers should be approximately correctly placed.
Please mark in hands to show 10 minutes past eleven o'clock (11:10).
For a correct response (above), the hands should be pointing to the 11 and the 2,
but do not penalise if the respondent fails to distinguish the long and short hands.
Information
Can you tell me something that happened in the news recently? (recently = in the last week)
Respondents are not required to provide extensive details, as long as they demonstrate awareness of a recent news story.
If a general answer is given, such as "war", "a lot of rain", ask for details.
If unable to give details, the answer should be scored as incorrect.
Recall
What was the name and address I asked you to remember?
Score for each of the 5 components - John, Brown, 42, West Street, Kensington.
  GPCOG Patient Score =  /9
GPCOG Informant Interview
Ask the informant: "Compared to a few years ago"
Does the patient have more trouble remembering things that have happened recently?
Does he or she have more trouble recalling conversations a few days later?
When speaking, does the patient have more difficulty in finding the right word or tend to use the wrong words more often?
Is the patient less able to manage money and financial affairs (e.g., paying bills, budgeting)?
Is the patient less able to manage his or her medication independently?
Does the patient need more assistance with transport (either private or public)?
Score 1 point for each "no" answer.
  Informant Score =  /6
Combined (overall) score =  /15 Overall
