The implication is that doctors see a problem and are monitoring his cognitive decline through multiple tests.No. Address multiple MoCA tests and their implication.
If a person had an EKG and it's normal, doctors will say "See ya next year!". If it's abnormal, they'll say "come back in 3 months". Same with cognitive or other medical tests.
Most older people like myself have had a colonoscopy. If things are normal, which they have been for me the past 30 years, it's "See you in 10 years". Sadly, the past one showed a few small polyps so it was "Come back in 3 years".
