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, ie 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 an informant questionnaire, a score of 3 or less out of 6 in this section indicates cognitive impairment.
