Introduction

Psychosis represents an uncommon but serious complication in the course of HIV infection, and always requires a careful differential diagnosis.

Objectives

To provide an overview of psychosis in HIV-infected patients.

Methods

Literature review based on PubMed/MEDLINE, using the keywords “HIV” and “psychosis”.

Results

Psychosis in HIV-positive individuals can be divided into psychotic disorders predating HIV infection and new-onset psychotic disorders in HIV-seropositive patients. The pathophysiology of psychosis in this population is complex and a multifactorial etiology is likely in most instances. The authors will analyze them and describe the differences of psychopathological pattern in first-episode psychosis between HIV-positive and HIV-negative patients. Antipsychotic agents are the treatments of choice regardless of the underlying diagnosis. However, they should always be used at the lowest possible dose for the shortest possible duration. Increased sensitivity to extrapyramidal reactions, high risk for dyslipidemia and hyperglycemia, potential interactions between HAART and some antipsychotic agents are also important considerations. Importantly, psychosis may be a harbinger of dementia. Cross-sectional studies have also suggested that psychosis may adversely impact the morbidity and mortality associated with HIV-infection.

Conclusions

Psychosis disorders may arise before or at any time during the course of HIV infection. A solid understanding of the complex relationship between psychosis and HIV allows for better evaluation and more effective treatment for psychotic individuals at risk for or infected with HIV. Thus, both HIV care programs and psychiatric care clinics should be made familiar with this important subject.
