Background and purpose: Stroke is a medical emergency that can cause permanent neurological damage, complications, and disability. We aim to determine the epidemiology of non-fatal cerebrovascular stroke (CVS) and transient ischemic attacks (TIAs) in Al Quseir City, Red Sea, Egypt.
Methods: The total population (n=33,285) was screened through a door to door study by three specialists of neurology and 15 female social workers (for demographic data collection). All suspected stroke patients were subjected to a full clinical examination, computerized tomography (CT) and/or magnetic resonance imaging (MRI) of their brain, blood sugar, lipogram, serum uric acid, complete blood cells, blood urea, and serum creatinine, as well as evaluated by Barthel Index and Scandinavian Stroke Scale. Carotid doppler, echocardiography, and thyroid functions were done for selected cases.
Results: CVS was recorded among 130 patients out of 19,848 subjects aged 20 years and more, yielding a total prevalence of 6.55/1,000 population. From June 1, 2010 to May 31, 2011, 36 patients were recorded to have stroke within 1-year, yielding an incidence rate of 1.81/1,000. Prevalence and incidence rates were higher among males than females, and both indices increased steadily with advancing age to reach the highest prevalence (37.02/1,000) and incidence rate (9.5/1,000) among aged persons 60 years and more.
Conclusion: The prevalence of non-fatal stroke in Al Quseir city (6.55/1,000) was at the lower range of that recorded in developing countries (5–10/1,000) and slightly higher than that recorded in industrialized countries (5/1,000 population). Ischemic stroke is the most common type of stroke. The prevalence of TIAs was 0.15/1,000.
