Abstract

With the aging of the population, cognitive impairment is becoming frequent. Thus, a study was conducted to estimate its prevalence in a Senegalese elderly population 60 years and over living in the commune of Diourbel, Senegal. A cross sectional study was conducted from July to august 2007 in a population of elderly aged 60 years and over living in the commune of Diourbel, Senegal to screen for cognitive impairment. Data on sociodemographic characteristics, lifestyles, physical activity, social network, medical history, familial history of dementia were collected with a structured questionnaire. Interviews were completed with a clinical exam and neuropsychological testing with the Test of Senegal. Cognitive impairment was defined as a score of ≤ 28/39 with the Test of Senegal. The population (584 elderly) had a mean age of 69.5 years (±7.3), was mostly female (54%), married (74.6%), and illiterated (80.1%).  Social network was poor, alcohol and smoking rare. Hypertension (58%), arthritis (45.9%), gastro-intestinal diseases (38.2%), anemia (29.5%) and cataract (22.9%) were the main health conditions reported. History of dementia was reported by 26.2%. Prevalence of cognitive impairment was 20.7% (95% CI: 17.7%-23.7%). This prevalence was more frequent among female and illiterated elderly persons. Prevalence of cognitive impairment was high and more frequent in female and illiterated elderly population living in the commune of Diourbel, Senegal.
