To facilitate continuity of cognitive tracking in individuals tested with MMSE, MoCA-30, and MoCA-Blind/ Telephone MoCA at different times and to provide comparability of data among multiple studies and trials, the ability to equate scores of these three tests is necessary. The MoCA-30 is more sensitive to mild forms of cognitive impairment, has a higher diagnostic accuracy than the MMSE, and is available at no cost. Recently, many clinical and research settings have switched to using the MoCA-30/ MoCA-Blind/ Telephone MoCA from the Mini-Mental State Exam (MMSE), another common screening measure. However, no norms for MoCA-30 subtests and domains or MoCA-Blind/ Telephone MoCA total score have been published for the oldest-old. To address the need for telephone cognitive screening, Telephone MoCA, identical to MoCA-Blind with slightly modified testing procedures to accommodate telephone testing, was developed and normative cut-points published for younger-old. The second challenge in testing the oldest-old is that prevalent frailty and other comorbidities prevent many of them from travelling to testing sites, which makes telephone screening a method of choice. Henceforth, the sum of in-person MoCA-30 subtests included in MoCA-Blind, that has maximum possible score of 22, is called MoCA-22. MoCA-Blind normative cut-points, to distinguish cognitively normal from cognitively impaired younger-old, were published for the sum of in-person MoCA-30 subtests included in MoCA-Blind. Additionally, MoCA-Blind, that includes MoCA-30 subtests that do not require visual input and has a maximum possible score of 22, was developed to enable in-person cognitive screening of individuals with visual impairment. In that vein, subtest and domain norms in younger-old (older adults younger than 90 years) have been published for one of the most frequently used screening measures, the in-person Montreal Cognitive Assessment that has a maximum possible score of 30 (MoCA-30). In such situations, subtest and domain norms allow for evaluation of completed subtests. First, sensory and cognitive impairments make many of the oldest-old unable to complete all subtests of in-person screening measures, which makes calculation of the total score and its comparison to normative values impossible. However, cognitive testing of this age group is challenging. The equivalences of the three cognitive tests (MMSE, MoCA-30, MoCA-22) in the oldest-old will facilitate continuity of cognitive tracking of individuals tested with different tests over time and comparison of the studies that use different cognitive tests.Ĭognitive screening of the oldest-old (age 90 +) has become increasingly important, because this age group has the highest risk of dementia and its projected growth in the coming decades is rapid. Subtest, domain and MoCA-22 norms will aid in evaluation of the oldest-old who cannot complete the MoCA-30 or are tested over the phone. An MMSE score of 27 is equivalent to a MoCA-30 score of 22 and a MoCA-22 score of 16. MoCA-22 total score norms are: mean = 18.3(standard deviation = 2.2). Second, we derived score equivalences for MMSE to MoCA-30 and MoCA-22, and MoCA-30 to MoCA-22 using equipercentile equating method with log-linear smoothing, based on all 157 participants. These norms were derived from 124 participants with a Mini-Mental State Examination (MMSE) ≥ 27. First, we derived norms for (1) subtests and cognitive domains of the in-person Montreal Cognitive Assessment having a maximum score of 30 (MoCA-30) and (2) the total MoCA-22 score, obtained from the in-person MoCA-30 by summing the subtests that do not require visual input to a maximum score of 22. Methodsĭata on 157 participants of the Center for Healthy Aging Longevity Study aged 90 + were analyzed. To provide norms and score equivalence for commonly used cognitive screening tests for the oldest-old. However, norms and score equivalence for screening tests are lacking for this group. This age group is the fastest growing and has the highest risk of dementia. Cognitive screening is important for the oldest-old (age 90 +).
