“…However, both the prevalence of cognitive impairment and dementia in our study were lower than those reported by the health center of the Senegalese national retirement institution (respectively, 7.7 vs. 10.8% for cognitive impairment [28] and 3.2 vs. 6.6% for dementia [14]). Methodological differences might partly explain the variability of the findings.…”

“…The prevalence of dementia in retired older people in this study is also comparable to that in the general population as evaluated in Nigeria in West Africa [10], even if other studies from Nigeria show higher results [11][12][13]. However, both the prevalence of cognitive impairment and dementia in our study were lower than those reported by the health center of the Senegalese national retirement institution (respectively, 7.7 vs. 10.8% for cognitive impairment [28] and 3.2 vs. 6.6% for dementia [14]).

“…In other central African countries, the prevalence in the general population was estimated at 8.8% (95% CI 6.4–11.8) in Nola, Central African Republic (CAR), and 6.0% (95% CI 4.1–8.4) in Bangui, Congo [8, 9]. In west Africa, more evidence is available, with prevalence estimates of between 2.3 and 10.1% in the general population in Nigeria [10-13], and 6.6% (95% CI 5.1–8.5) in the older population at the health center of the Senegalese national retirement institution [14].…”

Introduction: The number of people living with dementia is growing worldwide and most rapidly in low-and middleincome countries. Little is known about dementia in Benin. We estimated the prevalence of dementia among retired people in Parakou, a northern city in Benin, and then assessed associated factors. Methods: A cross-sectional study was performed in Parakou from July to August 2014. Participants were recruited at 2 centers, the National Center of Social Security and the Public Treasury of Benin. Participants with cognitive impairment were defined as having a low cognitive score (< 7) for the brief version of the Community Screening Interview for Dementia and were invited to neurological examination. DSM-IV-TR criteria were used to diagnose dementia and the HACHINSKI score was used to differentiate dementia subtypes. A logistic regression model was performed to identify factors associated with dementia. Results: Overall, 440 retired people were included in the study. They were mainly male (92.3%) and their mean age was 64.9 ± 6.0 years. The prevalence of cognitive impairment was 7.7% (95% CI 5.2-10.2). Fourteen participants were diagnosed with dementia, representing a prevalence of 3.2% (95% CI 1.5-4.8). Alzheimer disease was the most frequent subtype (64.3%), followed by vascular dementia (21.4%). Retired people diagnosed with dementia were all men and were aged between 61 and 71 years. Most of them were living alone. The main factors associated with dementia were older age, low fruit and vegetables consumption, and living alone. Discussion: This study showed a low prevalence of dementia among retired older people in Benin. Despite this, greater attention must be given to the potential burden dementia places on families for better care, before the expected aging of the population becomes more significant.

“…The diagnosis of Alzheimer’s disease was based on the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer’s Disease and Related Disorders Association (NINCDS/ADRDA) criteria [ 30 , 32 , 34 , 35 , 41 , 43 , 48 , 50 , 52 - 56 , 75 ]. Population-based studies that used DSM-III/DSM-IV and ICD-10 for dementia reported prevalences ranging from 1.1 to 8.1% [ 32 , 35 , 42 , 49 , 55 - 57 , 65 , 67 , 74 ] (ref 13, 16, 23, 30, 36–38, 48, 50, 118). Likewise the prevalence of Alzheimer’s disease ranged from 0.7 to 5.6% based on NINCDS/ADRDA criteria [ 35 , 42 , 55 ].…”

Epidemiology of neurodegenerative diseases in sub-Saharan Africa: a systematic review

2014

BackgroundSub-Saharan African (SSA) countries are experiencing rapid transitions with increased life expectancy. As a result the burden of age-related conditions such as neurodegenerative diseases might be increasing. We conducted a systematic review of published studies on common neurodegenerative diseases, and HIV-related neurocognitive impairment in SSA, in order to identify research gaps and inform prevention and control solutions.MethodsWe searched MEDLINE via PubMed, ‘Banque de Données de Santé Publique’ and the database of the ‘Institut d’Epidemiologie Neurologique et de Neurologie Tropicale’ from inception to February 2013 for published original studies from SSA on neurodegenerative diseases and HIV-related neurocognitive impairment. Screening and data extraction were conducted by two investigators. Bibliographies and citations of eligible studies were investigated.ResultsIn all 144 publications reporting on dementia (n = 49 publications, mainly Alzheimer disease), Parkinsonism (PD, n = 20), HIV-related neurocognitive impairment (n = 47), Huntington disease (HD, n = 19), amyotrophic lateral sclerosis (ALS, n = 15), cerebellar degeneration (n = 4) and Lewy body dementia (n = 1). Of these studies, largely based on prevalent cases from retrospective data on urban populations, half originated from Nigeria and South Africa. The prevalence of dementia (Alzheimer disease) varied between <1% and 10.1% (0.7% and 5.6%) in population-based studies and from <1% to 47.8% in hospital-based studies. Incidence of dementia (Alzheimer disease) ranged from 8.7 to 21.8/1000/year (9.5 to 11.1), and major risk factors were advanced age and female sex. HIV-related neurocognitive impairment’s prevalence (all from hospital-based studies) ranged from <1% to 80%. Population-based prevalence of PD and ALS varied from 10 to 235/100,000, and from 5 to 15/100,000 respectively while that for Huntington disease was 3.5/100,000. Equivalent figures for hospital based studies were the following: PD (0.41 to 7.2%), ALS (0.2 to 8.0/1000), and HD (0.2/100,000 to 46.0/100,000).ConclusionsThe body of literature on neurodegenerative disorders in SSA is large with regard to dementia and HIV-related neurocognitive disorders but limited for other neurodegenerative disorders. Shortcomings include few population-based studies, heterogeneous diagnostic criteria and uneven representation of countries on the continent. There are important knowledge gaps that need urgent action, in order to prepare the sub-continent for the anticipated local surge in neurodegenerative diseases.
