title: HIV-associated dementia: clinical, epidemiological and resource utilization issues.
abstract: Among mental disorders associated with HIV infection, dementia is the one most likely to have a major impact on public health, both as a result of the high levels of individual disability, and the greater demand of health care resource utilization. Epidemiologic and economic impact of HIV-associated dementia needs to be estimated, in order to provide policy makers and health managers with the information required for decision making and resource allocation. An increase in HIV encephalopathy prevalence rates may be expected as a consequence of longer survival time in dementia patients and in patients with other AIDS defining disease (longer survival increases the risk of developing HIV encephalopathy). A resource utilization study shows that, in the chronic stage of the disease, in-patient days per person-year are almost double in AIDS subjects with neurological complications as compared with those without neurological complications; no major difference appears when considering out-patients consultations and day-care treatments. In conclusion, a significant rise in resource utilization and in related costs may be anticipated as a consequence of the increasing prevalence of HIV encephalopathy. Further studies seem necessary to compare different approaches in the management of this debilitating disease, in view of a more rational utilization and allocation of resources.
