Comparison of cognitive function tests AD8-INA against MoCA-INA and CDT in the elderly age group at the Uabau Health Center


Background: Dementia is a syndrome of decreased cognitive ability that hinders daily life. Dementia is associated with mortality, especially in patients with major depression, so health services are needed to identify cognitive disorders through pre-elderly and elderly screening. AD8-INA is one of the cognitive screening methods where the questions are directed to patient caregivers that are most practical, concise, and suitable for patients who cannot use their dominant hand, so researchers are interested in studying the sensitivity and specificity of AD8-INA to MoCA-INA and CDT.

Methods: A cross-sectional study design was used to observe and analyze cognitive function variables. This study used primary data sources with interviews based on questionnaires on 114 subjects, consisting of pre-elderly and elderly groups who met the eligibility criteria to be included in the study. The MoCA-INA scores were divided into 26 normal and 26 cognitive impairments, the CDT scores 4 normal and 4 cognitive impairments, and the AD8-INA scores 0–1 normal and 2 cognitive impairments. An analysis was carried out to determine the sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and confidence interval.

Results: It was found that the sensitivity of AD8-INA to MoCA-INA was 87.14%, AD8-INA to CDT was 82.14%. In addition, the specificity of AD8-INA to MoCA-INA was 50% and AD8-INA to CDT was 61.11%.

Conclusion: AD8-INA has high sensitivity but low specificity. AD8-INA can still be used as an initial screening tool for cognitive function at the Uabau Health Center, but all examination results must be evaluated further.
