The spectrum of neurological disorders presenting at a neurology clinic in Yaoundé, Cameroon

Abstract

INTRODUCTION: The burden of these neurological diseases is higher in developing countries. However, there is a paucity and scarcity of literature on neurological diseases in sub-Saharan Africa. This study was therefore undertaken to determine the pattern of neurological diseases in this setting and then, compare to those elsewhere in the African continent and also serve as a baseline for planning and care for neurological disorders in Cameroon. METHODS: The study was conducted at the Clinique Bastos, in Yaoundé, city capital of Cameroon, centre region. Over a period of six years, all medical records were reviewed by a neurologist and neurological diagnoses classified according to ICD-10. RESULTS: Out of 4526 admissions 912 patients (20.15%) were given a neurological diagnosis. The most frequent neurological disorders were headache (31.9%), epilepsy (9.86%), intervertebral disc disorder (7.67%), followed by lumbar and cervical arthrosis, polyneuropathy, stroke, Parkinson disease and dementia. According to ICD-10 classification, Episodic and paroxysmal disorders (headaches, epilepsy, cerebrovascular, sleep disorders) were observed on 424 (46.48%) patients; followed by nerve, nerve root and plexus disorders in 115 (12.6%) patients. CONCLUSION: The above data emphasizes that neurological disease contributes substantially to morbidity in an urban African hospital. Headaches, epilepsy and intervertebral disc disorders are major causes of morbidity.
