THE COGRISK: A STRUCTURED COGNITIVE HISTORY TOOL

The CogRisk is a freely available, validated cognitive assessment tool for informants of a patient with suspected cognitive impairment. Ideally suited for waiting room use, the CogRisk is a two-page questionnaire for informants to complete that captures both current cognitive symptoms and actuarial risk variables for cognitive impairment. It allows not just for an exhaustive cognitive history to be taken highly efficiently, but also facilitates a clinician's greater focus on a particular "flagged" area of cognitive impairment.

The CogRisk takes under ten minutes to complete. One strong indirect benefit we have noticed through its use is it allows family and carers to feel heard about their concerns about an individual's cognitive or behavioural changes, and strongly engages caregivers in the cognitive assessment process. The CogRisk takes less than ten minutes to complete.
VALIDATION OF THE COGRISK

In our original validation paper, we showed that the CogRisk showed strong internal consistency, and correlated strongly with scores on the NUCOG and MMSE. Its sensitivity and specificity for detection of dementia proved to be roughly similar to using the NUCOG, and combining its use with the NUCOG significantly increased its capacity to detect cognitive impairment.
