People with dementia will either start to count down by the wrong amount, start counting up, stuff like that. You are testing whether they can abstract verbal instructions and maintain a consistent train of thought while performing trivial calculations.
Counting down on your fingers one by one and only saying every seventh number would be considered a perfect score once you make it to about 63 if you don’t lose track of what you are doing or start forgetting numbers.
Corn sugar is made up of a pretty large amount of glucose, so eating corn is like eating one of the shock tabs. Which is also a good way to confirm that it’s glucose; rice, beans, and chocolate cake all contain pretty small amounts of just glucose, the other sugars need time to break down.
