The General Practitioner Assessment of Cognition (GPCOG) is a brief cognitive screening instrument designed for primary care and community settings. The patient section is scored 0-9; intermediate scores typically trigger an informant section to improve screening accuracy before full diagnostic workup.
Formula: Patient section score range 0-9; intermediate scores typically require informant-section follow-up.

The GPCOG patient section consists of 9 scored items across three areas: (1) time orientation — ask the patient for the date (day, month, year, and day of week), scoring 1 point per correct response (maximum 4 points); (2) clock drawing — ask the patient to draw a clock showing 10 past 11 on a blank circle, scoring clock performance on a standard pass/fail basis (1 point); (3) recent news recall — ask the patient to report something they heard or read in the news recently and then to repeat it (correct recall scores 1 point). Additional orientation items complete the 9-point total. The patient section takes approximately 5 minutes to administer and requires only paper and a pen. Score the patient section immediately.
GPCOG patient section scores are interpreted in three bands: a score of 0–4 indicates probable cognitive impairment and warrants further diagnostic evaluation; a score of 9 suggests normal cognition and likely no further assessment needed; a score of 5–8 falls in the intermediate range and is considered inconclusive — these patients require the GPCOG informant interview to clarify cognitive status. The intermediate band is the key innovation of GPCOG: rather than relying solely on a patient test score that can be confounded by education, anxiety, and cooperation, GPCOG uses informant history to reduce false positives and negatives in this ambiguous range.
For patients scoring 5–8 on the patient section, administer the 6-item GPCOG informant interview to a person who knows the patient well (family member, carer, friend who sees the patient at least weekly). The informant is asked whether, compared to 10 years ago, the patient has more trouble with: remembering recent events; recalling conversations; finding words; managing money and finances; managing medications; and using transport independently. Each yes (decline present) response scores 1 point. Informant score of 0–3 suggests probable impairment when combined with an intermediate patient score; informant score of 4–6 suggests likely normal cognition. A combined score across patient and informant sections guides final interpretation and referral decisions.
General practitioners, family physicians, primary care nurse practitioners
GPCOG was specifically designed for primary care use, addressing the practical barriers to cognitive screening in busy general practice settings: time pressure, limited test materials, variable patient literacy, and the availability of accompanying family members. At annual health visits for patients aged 70 and above, the GPCOG patient section can be embedded into the appointment as a routine 5-minute screen. When the patient's spouse or adult child is accompanying them — common at geriatric GP visits — the informant interview can be administered simultaneously in a separate room by a practice nurse while the GP completes the patient section, maximizing efficiency. The GPCOG's two-stage design means that only patients with intermediate scores require the additional informant step.
Memory clinic coordinators, geriatric outpatient nurses, memory clinic GPs
Memory clinics receive referrals from primary care for cognitive assessment, but referral quality varies widely in terms of specificity. The GPCOG can be administered by a memory clinic nurse at the time of referral intake or at the initial appointment to rapidly triage cognitive status and prioritize assessment intensity. Patients scoring 0–4 on the patient section likely need full neuropsychological evaluation and dementia workup; patients scoring 9 may be reassured and monitored without full investigation; patients scoring 5–8 require the informant interview, which often clarifies whether full assessment is warranted. GPCOG-based triage improves memory clinic resource allocation by targeting intensive investigation to those most likely to benefit.
Rehabilitation physicians, post-acute care nurses, occupational therapists, physiotherapists
Cognitive impairment is common in rehabilitation settings and significantly affects rehabilitation outcomes — patients with cognitive impairment require more intensive supervision, are at higher fall risk, and have longer rehabilitation stays. The GPCOG provides a brief structured cognitive screen that can be applied at rehabilitation admission to identify patients who need cognitive support strategies, additional supervision, and family caregiver involvement in rehabilitation planning. The clock drawing component is particularly informative for occupational therapists assessing visuospatial abilities relevant to driving, kitchen safety, and home management tasks.
Occupational therapists, driving assessors, rehabilitation physicians, DVLA liaison physicians
Driving cessation is one of the most impactful and emotionally sensitive outcomes of cognitive impairment assessment, affecting independence, quality of life, and social participation. The GPCOG clock drawing component directly assesses visuospatial function — a key determinant of driving fitness — and the informant interview explicitly asks about transport independence, which serves as a collateral indicator of driving-related functional decline. A GPCOG score suggesting probable cognitive impairment in a patient who still drives should trigger referral for formal driving assessment and further cognitive evaluation. The informant-corroborated evidence of driving difficulties adds important objective weight to driving fitness discussions with patients who may lack insight into their own cognitive limitations.
Aged care facility nurses, geriatric care managers, resident assessment officers
In residential aged care facilities (RACFs) and assisted living settings, periodic cognitive monitoring is required for care planning, behavioral symptom management, and medication review. The GPCOG provides a brief but clinically meaningful cognitive screen that is well-suited to the residential aged care setting: no special equipment is required, the staff informant interview leverages facility nursing staff familiarity with residents, and the brief patient section minimizes respondent burden for frail elderly residents with limited tolerance for lengthy assessments. GPCOG scores can trigger occupational therapy review, psychiatric consultation for behavioral symptoms, and medication review for anticholinergics and other cognition-impairing medications.
The GPCOG informant interview is only valid if administered to someone who has close, regular, in-person contact with the patient — ideally someone who sees the patient at least several times per week. A spouse, adult child living with the patient, or primary carer is the ideal informant. A neighbor or friend who sees the patient only occasionally may not have sufficient observational knowledge to accurately answer the six informant questions about functional decline. Document who served as the informant and their relationship and frequency of contact with the patient.
When a patient scores 9 (the maximum) on the patient section, the informant interview is not administered. A perfect patient section score indicates very low probability of clinically significant cognitive impairment. While a score of 9 does not exclude the possibility of very early cognitive decline, it is an efficient screen-negative that avoids unnecessary further assessment in the vast majority of cases. Document the patient section score as the final GPCOG result when it is 9.
Some patients — particularly those presenting with subjective memory complaints who are anxious about memory testing — perform below their true cognitive level on the GPCOG patient section due to performance anxiety rather than genuine cognitive impairment. An intermediate patient section score (5–8) driven by high anxiety in a patient whose informant reports fully intact day-to-day functioning should be weighted toward the informant history in clinical interpretation. Consider retesting the patient section in a calmer setting if significant anxiety is documented.
The GPCOG informant interview is straightforward enough to be reliably administered by a trained practice nurse or healthcare assistant rather than requiring physician time. In a team-based primary care model, the nurse can administer the informant interview concurrently while the GP examines the patient, then share the results before the GP consultation concludes. This delegation model allows GPCOG to be completed within a standard GP appointment time without adding physician workload.
The GPCOG clock drawing component specifies asking the patient to show 10 past 11 (11:10), which is distinct from the 10:10 instruction used in standalone CDT and Mini-Cog administrations. The different time target is intentional in the GPCOG and should be maintained consistently for standardized scoring. Administering the GPCOG clock drawing with a different time instruction (e.g., 10:10) changes the difficulty and scoring criteria and invalidates comparison with GPCOG normative data.
The GPCOG patient section includes items (date orientation, clock drawing, news recall) that are moderately influenced by educational attainment. Patients with low formal education may perform in the 5–8 intermediate range for educational rather than cognitive pathological reasons. In these cases, the informant interview is especially important — a low-education patient whose informant reports fully intact day-to-day functional cognition is likely to have a low patient score driven by education rather than dementia. Supplement with education-adjusted alternatives such as the [SLUMS](/tools/slums-score) when low education is a significant confound.
GPCOG was developed for primary-care use and has validation data supporting practical dementia screening performance.
Lower GPCOG patient scores indicate greater cognitive concern, while intermediate scores need informant clarification.
Use in primary care, outpatient geriatrics, or community screening where a brief cognitive triage tool is needed.
Interpretation can be affected by education, language, hearing/vision deficits, and informant availability.
