Background: About 63% of people living with mild cognitive impairment (MCI) and dementia live in low- and middle-income countries (LMICs). Emerging evidence suggests that early risk factors for the development of MCI and dementia can be modified by public health and preventive intervention approaches.Aim: This study aimed to assess the prevalence of MCI in older adult patients and its relationship with some risk factors.Setting: The study was conducted among older adults at the Geriatric Clinic of the Family Medicine Department of a hospital in southern Nigeria.Methods: A cross-sectional study was carried out involving 160 subjects aged 65 years and above over a period of 3 months. Socio-demographic and clinical data were obtained using an interviewer-administered questionnaire. Subjects were accessed for impaired cognition using the 10-word delay recall test scale. Data were analysed using SPSS version 23.Results: There were 64 males and 96 females; male to female ratio was 1:1.5. Majority of the study population were in age range of 65–74 years. The overall prevalence of MCI was 59.4%. Respondents with tertiary education were 82% less likely to have MCI on logistic regression analysis (OR = 0.18, 95% CI = 0.465–0.719).Conclusion: Mild cognitive impairment was prevalent among older adults in this study and was found to be significantly associated with low level of education.Contribution: It is therefore recommended that screening for MCI and known risk factors should be prioritized at geriatric clinics.

Dementia is a global public health problem with increasing prevalence and incidence worldwide. The African continent is expected to bear the biggest brunt of the burden of dementia by 2050 because of the rapid demographic changes, including rapid population growth, an increase in life expectancy, and ageing. However, French-speaking Sub-Saharan African (FS-SSA) countries are underrepresented in research on dementia in Africa. While the reasons are diverse and complex, linguistic and cultural barriers to research, disproportionately affect these countries and may be significant factors. Any efforts, therefore, to redress the burden of dementia in Africa must consider the specific demographic, cultural, and linguistic characteristics of FS-SSA countries. This scoping review explores the current state of knowledge in dementia and cognitive impairment in Sub-Saharan Africa, highlighting research gaps and specific patterns unique to FS-SSA Africa. We identify pathways for research to bridge the knowledge gaps on dementia in FS-SSA as part of the global endeavor to tackle dementia worldwide.

Mild cognitive impairment and dementia in a heterogeneous elderly population: prevalence and risk profile

et al. 2013

Objective: To describe the demographic, clinical and risk profile of Mild Cognitive Impairment and dementia in a sample of elderly South Africans within a residential setting. Method: One hundred and forty participants residing in a group of residential homes for the elderly were assessed by psychiatrists and assigned diagnoses of dementia or Mild Cognitive Impairment (MCI). Participants diagnosed with dementia were also offered haematological investigations and a CT scan of the brain. Results: The sample consisted of 140 participants comprising 46.4% White, 29.3% Coloured, 20% Asian and 4.3% Black participants. There were 97 (69.3%) females and 106 (75.7%) participants had less than 12 years of education. Eleven (7.9%) dementia and 38 (27.1%) MCI cases were diagnosed. Increasing age was associated with cognitive impairment (MCI and dementia) (p=.020) but there was no association between gender and cognitive impairment (p=.165). MCI was significantly associated with a lower education level (p=.036) and no association was found between depression (current-p=.646; past-p=.719) and dementia or MCI. The presence of vascular risk factors (n=140) ranged from 66.4% (hypertension) to 14.3% (stroke). Subjective memory complaints were significantly associated with cognitive impairment (p=.001). Except for the use of the telephone (p=.225) and the television (p=.08), impairment in all domains of instrumental activities of daily living that were assessed were significantly associated with a dementia diagnosis. Conclusion: The study showed that cognitive impairment was associated with increasing age and low education levels. The presence of vascular risk factors places this population at risk for future cognitive decline. ?? differences in the risk profile (low levels of cardiovascular risk and hypolipidaemia) in LAMIC populations may be contributing to the lower rates. 1 While the incidence and prevalence of dementia have been extensively studied in Western and European countries 5 there remains a dearth of similar studies from Africa. The few studies conducted in Africa prior to 2000 used small samples and was reported to have used 'non-standardised clinical assessments'. 10 Recent studies from Africa reported prevalence figures ranging from 2.6% to 8.1%. 11,12,13 Dementia studies from South Africa include a Western Cape sample of coloured people 14 , with a prevalence of 8.6%, and a Free State sample of indigenous Sotho-speaking elderly black people 15 , which reported a prevalence of 7.7%. This paper describes the clinical and risk profile of a sample of elderly participants who were assessed for the presence of dementia and MCI. In addition, the value of functional assessments and subjective memory complaints in case-finding are also explored. Keywords MethodThe study consisted of three stages: 1) Administration of dementia screening tools; 2) Clinical diagnostic evaluation for dementia; and 3) Administration of a neuropsychological battery of tests. SampleThe study population comprised residents (N=1450) of a ...
