My MIL was just given this test....scored a 9....but, she’s also lazy and obstinnate and sometimes just won’t answer a question or won’t finish something...so I question it. She was living on her own 5 weeks ago...sorta.
My mother scored 9 also, but after giving her turmeric for the last 5 years she would now do MUCH better...in fact, her gerontologist now sees no reason to administer any cognitive instrument.
