Summary
In Uganda, between 7.2% and 20% of individuals over 60 years old live with dementia, with increasing observations of cognitive impairment (CI) among the elderly in communities such as Mukono district. Early identification and management of CI are critical to prevent progression to severe stages. This brief synthesizes evidence on cognitive impairment screening tools adapted for use 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 screening, 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, often supported by the Consortium to Establish a Registry for Alzheimer’s Disease (CERAD) 10-word list. Other reliable tests include the Memory Alteration Test, Brain Health Assessment, Memory Impairment Screen, and Addenbrooke’s Cognitive Examination Revised. While these tools demonstrate high reliability in identifying CI in low-resource settings, their effectiveness depends on functional referral systems for definitive diagnosis. Screening raises public awareness and aids policymakers and health managers in planning appropriate services.
Policy message
Cognitive impairment can range from mild to severe, and its burden is largely attributed to Alzheimer’s disease, related dementias, and mild cognitive impairment. Regarding dementia, the Ascertain Dementia 8-item questionnaire (AD8) can accurately identify 91% of the cases, while the Identification of Dementia in Elderly Africans cognitive screen (IDEA) can identify 90%. For mild cognitive impairment, the Community Screening Instrument for Dementia (CSI-D) can accurately identify 92% of the cases, while the Montreal Cognitive Assessment (MoCA) can identify 90%. The AD8 questionnaire is also useful for screening for mild cognitive impairment, with the ability to accurately detect 80% of the cases
