Neurological disorders affected 8.5% of patients in Niger. Comas, paraplegias, and palsies were the most common syndromes, with medullar compressions and CNS infections being leading causes.

Area of Science:

  • Clinical Neurology
  • Epidemiology of Neurological Disorders
  • Tropical Medicine

Context:

  • Study conducted at the National Hospital of Niamey, Republic of Niger, from October 1981 to May 1986.
  • Analysis of 4820 patients residing in Western Niger.
  • Focus on the prevalence and etiological factors of neurological disorders in the region.

Purpose:

  • To determine the prevalence of neurological disorders in Western Niger.
  • To identify the most common neurological syndromes and their underlying etiologies.
  • To assess the frequency of specific neurological diseases, including infectious, vascular, and degenerative conditions.

Summary:

  • 8.5% of patients (410 out of 4820) presented with neurological disorders.
  • The most prevalent syndromes were comas, paraplegias, cranial nerve palsies, convulsions, hemiplegias, and sciaticas (75.2% of cases).

  • Leading etiologies included medullar compressions (Pott's disease), central nervous system infections (bacterial meningitis, cerebral malaria), cerebrovascular disturbances, and metabolic encephalopathies (73.5% of diagnosed cases).
  • Arterial hypertension was a significant factor in cerebrovascular attacks.
  • Parkinsonian syndrome and multiple sclerosis appeared rare; cerebral tumors were uncommon, possibly due to diagnostic limitations.

    • Impact:

    • Highlights the significant burden of neurological disorders in Western Niger.
    • Identifies key neurological conditions requiring attention and resources in the region.
    • Suggests a need for improved diagnostic capabilities, including advanced imaging and autopsy, to better understand less common neurological diseases and conditions like tuberculous meningitis in endemic areas.
