How can you assess anyone in five minutes, many things come into play.
Both DH and I were asked to do an 'instant' cognitive test, when we were, separately, taken to A&E. It seemed to be standard for anyone over about 70. Its purpose was to identify anyone who might be having cognitive problems, permanent, or caused by their health problem.
In each case the doctor was a bit apologetic because in both our cases it was clear that we were mental OK. It was quite simple we were asked the day of the week, month, year, date, approximate time, who the Prime Minister and monarch were. We were given an address (42, West Street, if anyone cares to prime themselves in advance), asked a couple more simple questions and then asked to repeat the address. The test took nly minutes
Not a test sufficient to diagnose dementia, but enough for the staff dealing with the patient to know how much they were likely to be understanding what was said to them and a context for assessing anything they said and, if there was concern refer them onward for further assessment.
For a GP in their surgery, using this quick test would be enough to decide to refer someone to a memory clinic for a more extensive assessment.
