Abstract
With the ageing of the population, dementia is increasing. In Africa, studies on dementia of the elderly are seldom. However, dementia exists and is not well documented in Senegal especially among the elderly population. We conducted a study to estimate the prevalence of this disease among Senegalese elderly population utilizing the Medico Social and University Center of IPRES, Dakar-Senegal. The study was cross-sectional and intended, through a two-wave process of data collection, to collect data from March 2004 to December 2005 among Senegalese elderly population (aged 65 years) over utilizing the MedicoSocial and University Center of IPRES, Dakar-Senegal for health care. Sociodemographic, medical history, lifestyles and social network data were collected with a structured questionnaire completed with a clinical examination and neuropsychological testing. Diagnosis of dementia was based on DSM IV criteria. The population composed of 507 patients with a mean age of 72.4 years (±5.25), mostly male, married, and non-educated. Hypertension, arthritis, gastro-intestinal, respiratory and urinary diseases were the main health conditions reported. The elderly population had a high social network. 45 patients (8.87; 95% IC: 7.61 to 10.13) had dementia in which prevalence varied significantly with age, education and social network. The results confirm the variability of dementia with age, education and social network at the Medico Social and University Center of IPRES, Dakar-Senegal.
