Depressive syndromes and symptoms in subjects with human immunodeficiency virus (HIV) infection

The association between the infection produced by the human immunodeficiency virus (HIV) and syndromal or subsyndromal depression has been the topic of several studies in recent years. The results of the WHO Neuropsychiatric AIDS Study, conducted in the five geographical areas predominantly affected by the HIV epidemic, suggest that the symptomatic stages of HIV infection are associated with an increased prevalence of depressive symptoms, and, at least in some contexts in which the spreading of the infection is more recent and the social rejection of HIV-seropositive subjects is harsher, may also be associated with an increased prevalence of a syndromal diagnosis of depression.
