“It’s a brief exam that assesses general cognitive function, but it lacks sensitivity to subtle cognitive decline,” according to Dr. David Knopman, chairman of the Alzheimer’s Association Medical and Scientific Advisory Council and a professor of neurology at the Mayo Clinic College of Medicine.

Knopman called the test “reliable and valid,” noting that it’s been around about 10 years, but said it doesn’t tell us everything.


“Because it’s a brief examination, it is not considered a definitive assessment of cognitive function,” Knopman told HuffPost. “More detailed neuropsychological testing should be performed if there are suspicions that a person has cognitive dysfunction despite their store on the MoCA.”
