[Neurological complications in 95 patients with HIV infection. A retrospective analysis of anamnestic and clinical data].

This retrospective investigation of neurological deficits in 95 consecutive patients (77 men, mean age 35 years; 18 women, mean age 28 years) infected by the human immunodeficiency virus showed that 61% of the female and 47% of the male patients exhibited neurological deficits. In 18% of the total population neurological deficits were the initial sign of acquired immunodeficiency. In addition, we found that a history of headaches and the clinical finding of mental impairment as well as internistic symptoms were significantly correlated with neurological deficits. Patients suffering from cerebral toxoplasmosis developed mental impairment significantly more often than patients with central nervous symptoms of other etiogenesis. Furthermore, it was found that HIV-infected women manifested peripheral neuropathies more often than HIV-infected men. The overall mortality rate over the investigation period of 30 months was 28%. The results of our retrospective investigation indicate that HIV-infected patients have a high risk of developing lesions of the central and peripheral nervous system during the course of the disease. Various reasons might be responsible for these findings: neurotropy and metamorphosis of the human immunodeficiency virus, opportunistic infections and tumors, vitamin deficiencies, and a variety of diseases prior to HIV-infection.
