Brain impairment is a distressing manifestation of human immunodeficiency virus (HIV) disease characterized by progressive cognitive impairment leading eventually to dementia and death. Patients with advanced brain impairment are clinically difficult to manage and usually require residential care. In 1997, a brain impairment unit opened at the Mildmay Hospital UK in London to meet the needs of this patient group. It began as a nurse-led unit, has adopted an interdisciplinary approach to care and aims to maximize the quality of life until death. In a study of patients admitted during its first year, it emerged that while the condition of many patients declined resulting in death, some patients improved sufficiently with rehabilitation and ongoing medical treatment to return to independent living. The possible reasons for this are discussed in this article. Study findings have not only affected the approach to care but have also highlighted some unexpected problems; the importance of adopting an interdisciplinary approach in caring for the group of patients becomes evident.
