Abstract

<i>Background:</i> With aging, there is a parallel increase in the prevalence of dementia worldwide. The aim of this work is to determine the prevalence of dementia among the population of Al Kharga District, New Valley, Egypt. <i>Methods:</i> Screening of all subjects aged ≥50 years (n = 8,173 out of 62,583 inhabitants) was done through a door-to-door survey by 3 neurologists, using a short standardized Arabic screening test and a modified Mini-Mental State Examination. Suspected cases were subjected to full clinical examination, psychometric assessment using the Cognitive Abilities Screening Instrument, Instrumental Activities of Daily Living Scale, Geriatric Depression Scale, Hachinski Ischemic Score, DSM-IV-TR diagnostic criteria, neuroimaging, and laboratory investigations, when indicated. <i>Results:</i> The prevalence rate of dementia was 2.26% for the population aged ≥50 years. It increased steeply with age to a maximum of 18.48% for those aged ≥80 years. Alzheimer’s disease (51.2%) was the most common subtype, followed by vascular dementia (28.7%), dementia due to general medical conditions (12.8%), and lastly dementia due to multiple etiologies (7.3%). Mild dementia was the commonest (53.7%). <i>Conclusion:</i> Dementia is prevalent in Egypt as elsewhere. Detection through a door-to-door surveyis the best method in developing countriesfor early detection of mild cases.
