Through a cohort of 93 neuroaids which has been diagnosed at Dakar in our Neurology Department, the authors evaluated the hospital prevalence of retrovirus, detected socio-demographic factors, related AIDS outline the mean neurological picture and try to correlate survival and neurological involvement of these patients. Among 1151 patients who got retroviral blood test, 93 were seropositive (8.1%). On these repartitions 36 were females (38.7%) and 57 males (61.3%). The age goes from 19 to 76 years old. 45 patients (48.4%) have been found positive for HIV-1 blood test, 21 patients (22.6%) for HIV-2 blood test, 11 patients (11.8%) for both HIV2, 11 patients (11.8%) for HTLV1, 3 patients (3.2%) for both HIV-1 and HTLV1, and 2 patients (2.2%) for both HIV-2 and HTLV1. In our study the transmission of AIDS occur mainly through heterosexual inter course and multiple parternship is a high risk group. The central nervous system deseases represented 68.8% of cases. The pathology were dominated by stroke, myelopathies, meningoencephalotis and spinal cord compression. The peripheral nervous system desease were found in 7.5% of cases. The peripheral facial paralysis occupied the first place in HIV infections of peripheral nervous system deseases (57.1% of cases). When neurological involvement set up the letality is higher for HIV-1 (57% of global letality) and for central system nervous involvement (76.2%).
