Quest’s testing panel may not turn up a huge number of treatable cases of dementia. Reversible forms are much less common than Alzheimer’s disease and others such as vascular dementia, said David Knopman, a member of the American Academy of Neurology and a professor of neurology at the Mayo Clinic in Rochester, Minnesota. “Unfortunately and disappointingly, it is exceedingly rare” to find cases of treatable dementia, he said in a telephone interview. Knopman was part of the group that wrote practice guidelines in 2001 for screening tests.
