Background Because of rapid demographic changes, the prevalence of movement disorders ( MD s) is expected to increase in Africa. The objective of this study was to estimate the prevalence of MD s in an inpatient/outpatient‐based study of rural and urban health care centers in Cameroon. Methods In this retrospective medical chart review, the inpatient/outpatients settings covered an urban population (3,000,000) and a rural population (380,276). Neurological diseases were classified according to the International Statistical Classification of Diseases‐Related Health Problems, 10th revision ( ICD ‐10). Crude prevalence was calculated per 100 with 95% confidence intervals ( CI s). Results Of 20,131 medical charts reviewed (13% from the rural area), 4187 patients (20.8%) with neurological complaints were identified. MD s were diagnosed exclusively from urban centers in 134 patients (3.2%): the mean patient age was 48.6 ± 18.6 years, and 54.7% were women. The most prevalent MD s were hyperkinetic movements (tremor, myoclonus, and drug‐induced MD s [ ICD ‐10 code G25]; prevalence, 1.19%; 95% CI , 1.192–1.194%), Parkinson's disease ( ICD ‐10 code G20; prevalence, 0.78%; 95% CI , 0.785–0.787%), dystonia ( ICD ‐10 code G24; prevalence, 0.61%; 95% CI , 0.612–0.613%), secondary parkinsonism ( ICD ‐10 code G21; prevalence, 0.56%; 95% CI , 0.564–0.565%), Huntington's disease ( ICD ‐10 code G10; prevalence, 0.09%; 95% CI , 0.091–0.092%), and ataxia ( ICD ‐10 code R29; prevalence, 0.04%; 95% CI , 0.0451–0.0456). Conclusion Although the burden of MD s is expected to increase, MD s are likely underdiagnosed in rural areas. High‐quality movement disorder training is essential to tackle this need.
