Multicenter Transversal Two-Phase Study to Determine a National Prevalence of Epilepsy in Algeria

Abstract

Background/Aims: The prevalence of epilepsy in Algeria is unknown. The aims of this multicenter transversal study were to determine the national prevalence and clinical characteristics of epilepsy in the Algerian population. Methods: This two-phase study was conducted in 5 circumscriptions and included 8,046 subjects aged over 2 months who attended the randomly selected public and private primary care clinics. In the phase 1 study, a questionnaire was submitted to the sample of patients. In the phase 2 study, all potentially epileptic people were examined by neurologists and a second questionnaire was submitted, eventually assessed by appropriate investigations. Results: Sixty-seven patients were identified as having active epilepsy, giving a crude prevalence ratio of 8.32 per 1,000 (95% CI, 6.34–10.3) and an age-adjusted prevalence ratio of 8.9 per 1,000. The highest age-specific ratio was found in patients aged 10–19 years (16.92 per 1,000). Generalized seizures (68.7%) were more common than partial seizures (29.8%). Perinatal injuries were the major leading putative causes (11.9%). Conclusion: The prevalence of epilepsy of 8.32 determined in this study is relatively high. These results provide new epidemiological data and suggest that epilepsy remains an important public health issue to consider in Algeria.

Consanguinity and epilepsy in Oran, Algeria: A case–control study

“…In Algeria, where the prevalence of epilepsy is estimated at 8.32/1000 (Moualek et al, 2012) and the rate of inbreeding at 38% (18% in Oran) (Fondation, 2007), very few epidemiological studies on epilepsy have been published and none has evaluated the association with risk factors.…”

“…15 In one study from Algeria, the prevalence rate was reported to be 8.32 per 1000. 21 In one study from Turkey, 22 the prevalence of active epilepsy was 5 per 1000 inhabitants. In a comparative epidemiology of epilepsy in Pakistan and Turkey, 23 the prevalence rate of epilepsy was 9.98 in 1000 people in Pakistan and 7.0 in 1000 persons in Turkey.…”
