Clinical context: when GPCOG is used

9-item cognitive screen designed for general practice with patient and informant components. GPCOG is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.

Like all screening or assessment instruments, GPCOG is a structured aid — not a diagnostic test in isolation. Results should be interpreted alongside history, examination, and clinical context. Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.

How GPCOG is scored

Patient component scored 0-9. Informant component 0-6 if needed. Total max 15. Score <= 4 suggests cognitive impairment.

Scoring notes: Patient component scored 0-9. Informant component 0-6 if needed. Total max 15. Score <= 4 suggests cognitive impairment.

How to score GPCOG: a step-by-step worked example

This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.

Step 1 — Score each item

Mark each item Yes or No. Each "Yes" adds the item's weight; each "No" adds 0. The example below uses illustrative answers.

#ItemExample responseScore
1Patient: Correctly recalls today's dateNo0
2Patient: Clock face — circle drawn correctlyYes1
3Patient: Clock face — numbers placed correctlyNo0
4Patient: Clock face — hands set to 11:10 correctlyYes1
5Patient: Recalls a recent news eventNo0
6Patient: Recalls full name from address (e.g., 'John')Yes1
7Patient: Recalls street number from addressNo0
8Patient: Recalls street name from addressYes1
9Patient: Recalls suburb/city from addressNo0
10Informant: Patient has more trouble remembering recent events than beforeYes1
11Informant: Patient has more trouble recalling conversations a few days laterNo0
12Informant: Patient has more difficulty finding the right wordYes1
13Informant: Patient is less able to manage money and financesNo0
14Informant: Patient is less able to manage medications independentlyYes1
15Informant: Patient needs more help with transport (driving, public transit)No0

Step 2 — Add up the scores

Add the weights from the items where you marked "Yes" (skip the "No" answers — they contribute 0).

0 + 1 + 0 + 1 + 0 + 1 + 0 + 1 + … (items 9–15 sum to 3) = 7

Step 3 — Look up the band

Find the row in the interpretation table whose range contains your total:

Total = 7 falls between 5 and 8Possible impairment

Step 4 — What does this mean clinically?

Possible impairment. Further evaluation

A score is one input alongside history and examination. GPCOG supports clinical judgment — it does not replace it.
