BackgroundTimely diagnosis of dementia is a global healthcare priority, particularly in low to middle income countries where rapid increases in older adult populations are expected.ObjectiveTo investigate global perspectives on the role of brief cognitive assessments (BCAs) in dementia diagnosis, strengths and limitations of existing measures, and future directions and needs.MethodsThis is a qualitative study of 18 dementia experts from different areas of the world. Participants were selected using purposeful sampling based on the following criteria: 1) practicing in countries with projected growth of older adult population of over 100%by 2050; 2) expertise in dementia diagnosis and treatment; 3) involvement in clinical practice and training; and 4) recognition as a national dementia expert based on leadership positions within healthcare system, research, and/or policy work. Participants were individually interviewed in their language of choice over secure videoconference sessions. Interviews were analyzed by a multidisciplinary team using theme identification approach.ResultsFour domains with subthemes emerged illustrating participants' perspectives: 1) strengths of BCAs; 2) limitations of BCAs; 3) needs related to the use of BCAs; and 4) characteristics of an ideal BCA. While most experts agreed that BCAs were important and useful for dementia diagnosis, the themes emphasized the need for development and validation of novel measures that are sensitive, psychometrically sound, and culturally appropriate.ConclusionBCAs are important for guiding diagnosis and care for dementia patients. Findings provide a roadmap for novel BCA development to assist in diagnostic decision making for clinicians serving a rapidly growing and diverse dementia population.

Background: Cognitive assessment is a key component of clinical evaluations for patients with dementia and Alzheimer's disease in primary health care (PHC) settings. The need for well-validated, culturally appropriate, and easy-to-use assessments is especially urgent in low- and middle-income countries (LMICs) that are experiencing rapid growth in their older adult populations. Objective: To examine the feasibility and demographic determinants of performance for a tablet-based cognitive assessment tool (TabCAT) battery, which includes subtests for four cognitive domains, among older PHC patients in southeastNigeria. Methods: A cross-sectional mixed-method descriptive study evaluating the useability and performance of TabCAT. Results: We enrolled 207 participants (mean age of 64.7±13.5 years; 52% with only primary, 41% secondary, and 7% tertiary education). Most (91%) who initiated the assessment were able to complete it, requiring 10–15 minutes to complete. More years of education was associated with better test scores across all tests (p < 0.001). Living in a rural location was also associated with better performance (p < 0.05). Male compared to female sex did not associate with performance on any of the tests (all ps > 0.05). Conclusions: Tablet-based cognitive assessment was feasible in rural and urban settings of Nigeria. Better performance on cognitive subtests linked to more education and residing in a rural area; however, sex did not predict performance. Digital cognitive assessment tools hold potential for widespread use in healthcare and educational contexts, particularly in regions with varying levels of urbanization and educational access.
