Tools Adapted for Screening Cognitive Impairment Among the Elderly at the Community Level in Africa

Summary

In Uganda, between 7.2% and 20% of individuals over 60 years old live with dementia, with increasing signs of cognitive impairment observed in communities such as Mukono district. Early identification and management of cognitive impairment (CI) are critical to prevent progression to severe stages. This brief synthesizes evidence on tools adapted for screening cognitive impairment among elderly populations in low-income African settings. Commonly adapted tools for mild cognitive impairment (MCI) include the Montreal Cognitive Assessment (MoCA), Ascertain Dementia 8-item questionnaire (AD8), Alzheimer’s Disease Assessment Scale (ADAS-Cog), and Community Screening Instrument for Dementia (CSI-D). For dementia, tools such as the Identification of Dementia in Elderly Africans (IDEA) cognitive screen and AD8 are used. These tools have been culturally adapted and modified to accommodate low literacy levels, demonstrating high reliability in identifying MCI and dementia in resource-limited settings. However, effective management requires a functional referral system for definitive diagnosis. The brief highlights the importance of culturally appropriate screening tools to raise awareness and inform policy and health service planning in African contexts.

Policy message

The cognitive impairment screening tools adapted for African communities have been modified to reflect cultural contexts and accommodate low literacy levels, so as to identify as many people as possible with such conditions. These adaptations include translation of the psychometric properties into local languages, making changes to some terminologies, and replacing less familiar items with those that the individuals in those communities are more familiar with.
