Objective:
Mild Cognitive Impairment (MCI) is defined as the “symptomatic pre-dementia stage” on the continuum of cognitive decline, characterized by objective impairment in cognition that is not severe enough to require help with usual activities of daily living (Langa et al., 2014). Literature on MCI prevalence greatly varies from Puerto Ricans having the highest prevalence (12.09%) (González et al., 2019) among Latino backgrounds to a prevalence of 3% (Sosa et al., 2012), and a hospital-based study suggesting that less than 1% of patients are being diagnosed with MCI (Scott et al., 2021). Although discrepancies can be attributed to different MCI classification systems, another reason is the limited neuropsychological instruments available for detecting MCI among Puerto Ricans, even more so among highly educated individuals. On the other hand, teleneuropsychology has arisen, but its access and use are still limited in Puerto Rico. Therefore, this research aims to explore whether the online version of the Spanish CERAD can detect neurocognitive differences between cognitively healthy adults and a statistically determined suspicious MCI group (S-MCI).
Participants and Methods:
114 cognitively healthy (Mini Mental State Examination [MMSE], M = 29.07, SD = 1.22) and community-dwelling Puerto Ricans (ages 55-92) residing on the Island completed the Online Spanish CERAD Battery. Retrospectively, 24 participants (age, M= 68.41, SD = 7.70; education, M = 15.41, SD = 3.05; MMSE, M= 28.58, SD = 1.34) were statistically determined as S-MCI if a score fell 1.5 SD below the overall sample mean on one or more tests (i.e., Wordlist or Letter Fluency). This S-MCI group was matched with a control group by age and education (n = 25; age, M = 68.36, SD = 6.84; education, M = 14.54, SD = 1.90; MMSE, M = 29.08, SD = 1.07). Parametric analysis was applied to both groups.
Results:
T-test analyses revealed no statistical differences in age (p = .978) or education (p = .232) across the S-MCI and the control group. Multivariate analysis of covariance (MANCOVA) showed a main effect of group membership on the combined dependent variables after controlling for covariates (age and education) with moderate effect size (p <.001; ηp2 = .624). Subsequent analysis of covariance (ANCOVA) showed that the S-MCI performed statistically significantly lower on 11 out of 14 test variables (except Logical Memory Recognition, Clothing Fluency, and Letter Perseveration).
Conclusions:
The S-MCI performed statistically significantly lower in tasks of verbal memory, naming, verbal fluency, attention, and working memory. These results suggest that the online version of the Spanish CERAD has the potential to identify significant cognitive differences in Puerto Ricans with MMSE scores ranging from 26-30 (96% of the overall sample scored between 27-30). These results support that the MMSE should be used with caution. Future
