Background/Methods: A door-to-door (‘every door’) study was carried out to assess the incidence and prevalence rates of epilepsy, stroke, Bell’s palsy and cerebral palsy, as well as the prevalence of dementia, extrapyramidal syndromes, muscle and neuromuscular disorders, cerebellar ataxia and primary nocturnal enuresis among the urban and rural populations of Al Kharga district, New Valley, Egypt. The study was carried out in 3 stages from June 1, 2005 to May 31, 2009. A door-to-door screening including every door was carried out using a standardized questionnaire, which was administered by 3 neurologists to all inhabitants (62,583) of Al Kharga district. The study was designed to assess the prevalence, incidence and risk factors of major neurological disorders in Al Kharga district and aimed to reduce the burden of these neurological disorders in the entire region. Results/Conclusions: This study clarified that dementia, primary nocturnal enuresis, epilepsy, stroke and cerebral palsy are the most common neurological disorders. On the other hand, Bell’s palsy, extrapyramidal syndromes, cerebellar ataxia, muscle dystrophies and myasthenia gravis are less common neurological disorders in Al Kharga district.
Epidemiology of neurological disorders is still lacking in Egypt. The door-to-door method is the most suitable one to screen neurological disorders in our country. Over a 4-year period (June 1, 2005 to May 31, 2009), screening and examination had been carried out to ascertain the incidence and prevalence rate of epilepsy, stroke, cerebral palsy and Bell’s palsy, as well as the prevalence of dementia, extrapyramidal syndromes, muscle and neuromuscular disorders, cerebellar ataxia and primary nocturnal enuresis among the urban and rural population of Al Kharga District, New Valley, Egypt. A total of 62,583 people were screened by 3 neurologists in a door-to-door manner, including every door, using a standardized Arabic questionnaire to detect any patient with a neurological disorder. This was a project study of neurological disorders including 3 stages: first stage (June 1, 2005 to May 31, 2006) for data collection, designing a standardized questionnaire and screening; second stage (June 1, 2006 to May 31, 2008) for case ascertainment, classification of neurological disorders and investigations, and third stage (June 1, 2007 to May 31, 2009) for data entry and statistical analysis. The results of this study revealed that the total prevalence rate of neurological disorders in Al Kharga District, New Valley was 2.4/100 with no significant difference among both sexes. The highest prevalence rate was recorded among elderly people (60+ years; 9.25%) and among children (≤18 years; 2.9%).
Background: Alzheimer's disease (AD) is the commonest type of Dementia worldwide. It rapidly increases with aging especially over 70 years. Objectives: The aims of this study are to determine the prevalence of AD in Egyptian desert areas and to identify the risk factors and presenting symptoms. Methods: This study was carried out on desert areas Al Kharga district and Al Quseir city. All population aged 50 years and more (12,508) were included through door to door survey by seven Neuropsychiatrists. They were screened by standardized questionnaire prepared specifically. Positive cases were invited to attend Assiut Univ. Hospital where clinical evaluation, according to DSM-IV R. and necessary psychometric tests were applied. Results: One hundred twenty-six patients with AD were diagnosed out of 12,508 people aged 50 years; yielding a prevalence of 1%. Prevalence increases with age, from 0.34% for those aged 60 ≤ 70 years to 2.9% for subjects aged 70 ≤ 80 years, and 9.74% for those aged 80 years and more. AD is more common among females than males in all ages. Eighty-five percent of diagnosed patients are of mild and moderate degrees. Hypertension (14.3%), smoking (10.3%), diabetes (8.73%), prior epilepsy (5.6%), and family history of AD (3.5%) are common risk factors. Impaired self-care (88.1%), memory loss (84.1%), impaired social judgment (77%), agnosia (58.7%), and behavioral changes (48.4%) are the most frequently encountered symptoms of AD. Conclusion: Prevalence of AD was 1% for population aged 50 years and more, reaching 9.7 for patients aged > 80 years. Early onset AD (< 65 years) was recorded in 7.9%.
