The neurological features of 10 patients with HIV-related disease seen in Glasgow between July 1984 and May 1988 are described. Two of these patients presented with ARC and eight with AIDS. Six patients showed features consistent with a diagnosis of AIDS-dementia complex, one had cerebral toxoplasmosis, one had CNS lymphoma, one had a probable drug-induced encephalopathy and one patient had a meningoencephalitis of undetermined cause. Seven of these patients have now died. The implications of these findings are discussed.
