title: Epidemiology of Acute Symptomatic Seizures among Adult Medical Admissions.
abstract: Acute symptomatic seizures are seizures occurring in close temporal relationship with an acute central nervous system (CNS) insult. The objective of the study was to determine the frequency of presentation and etiological risk factors of acute symptomatic seizures among adult medical admissions. It was a two-year retrospective study of the medical files of adults patients admitted with acute symptomatic seizures as the first presenting event. There were 94 cases of acute symptomatic seizures accounting for 5.2% (95% CI: 4.17-6.23) of the 1,802 medical admissions during the period under review. There were 49 (52.1%) males and 45 (47.9%) females aged between 18 years and 84 years. The etiological risk factors of acute symptomatic seizures were infections in 36.2% (n = 34) of cases, stroke in 29.8% (n = 28), metabolic in 12.8% (n = 12), toxic in 10.6% (n = 10), and other causes in 10.6% (n = 10). Infective causes were more among those below fifty years while stroke was more in those aged fifty years and above. CNS infections and stroke were the prominent causes of acute symptomatic seizures. This is an evidence of the "double tragedy" facing developing countries, the unresolved threat of infectious diseases on one hand and the increasing impact of noncommunicable diseases on the other one.
