DESIGN--Retrospective study of a consecutive series of patients with AIDS from 1982 to 1988. SETTING--An academic centre for AIDS. PATIENTS--196 Patients with AIDS and neurological symptoms examined from 1982 to 1988. INTERVENTIONS--Zidovudine treatment, which was introduced to The Netherlands on 1 May 1987 for patients with severe symptoms of HIV infection (Centers for Disease Control groups IVA, B, C, and D). MAIN OUTCOME MEASURES--Diagnosis of AIDS dementia complex and presence of HIV I p24 antigen in cerebrospinal fluid. RESULTS--The AIDS dementia complex was diagnosed in 40 of the 196 (20%) patients with AIDS. Thirty eight of 107 patients with AIDS (36%) not taking zidovudine developed the AIDS dementia complex compared with two of the 89 (2%) taking the drug (p less than 0.00001). The incidence of the AIDS dementia complex increased to 53% in the first half of 1987, after the introduction of zidovudine in May 1987, decreasing to 10% in the second half of 1987 and to 3% in 1988. Dementia was diagnosed before definition of the AIDS dementia complex (1986) according to DSM-III criteria and there was good agreement between diagnosis before and after 1986. Sixteen of 61 samples of cerebrospinal fluid (26%) from patients with AIDS (10 with the AIDS dementia complex) not taking zidovudine were positive for HIV I p24 antigen, whereas none of 37 cerebrospinal fluid samples from patients with AIDS (two with the AIDS dementia complex) taking zidovudine were positive. CONCLUSIONS--The incidence of AIDS dementia complex in patients with AIDS declined after the introduction of systematic treatment with zidovudine; the AIDS dementia complex might be prevented by inhibiting viral replication in the central nervous system.<\/jats:p>","DOI":"10.1136\/bmj.299.6703.819","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T15:19:55Z","timestamp":1238685595000},"page":"819-821","source":"Crossref","is-referenced-by-count":187,"title":["Declining incidence of AIDS dementia complex after introduction of zidovudine treatment."],"prefix":"10.1136","volume":"299","author":[{"given":"P.","family":"Portegies","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"de Gans","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.
