[Aetiological aspects of neurological diseases in Dakar: follow-up after 10 years (1986-1995)]. / Aspects etiologiques des affections neurologiques à Dakar: bilan de 10 années (1986-1995).

ABSTRACT

Because of the apparition of new risk factors and numerous progresses in investigation methods, authors take stock of neurological diseases of patients admitted in Clinique Neurologique of Fann during the last ten years. The 8539 cases repartition is as followed 4736 males and 3803 female. Their ages ranged between 3 and 80 years with 2130 deaths corresponding to 24.94%. Annual mean of admission is 853 +/- 42 cases. Aetiological data are stroke (3910 cases 45.78% with 60.56% of death). The following is peripheral neuropathieswith 714 cases(8.61%) and the spinal cord compression with 692 cases (8.10%). Comparision of frequencies of different aetiologies with those of previous studies shows that the small capacity of the neurological department is a restricting factor for the entry frequencies of neurological patients; the principal pathologies got small variations from one decade to another. In the opposite, some aetiologies have disappeared (neurological syphilitis, trypanosomiasis, neurocyticercosis, cerebral mycosis). Some eatiologies remain unprecised (infectious diseases, peripheral neuropathies, degenerative diseases).
