[Neurocognitive disturbances and psychiatric disorders among patients living with HIV-1 positive in Israel].

INTRODUCTION

Neurocognitive dysfunction and psychiatric disorders are common among people living with HIV. A large number of the patients are asymptomatic, but in neurocognitive assessment and specific questionnaires subclinical disturbances can be diagnosed. The aim of this research was to study the rate of neurocognitive disturbances, as well as psychiatric disorders (depression and anxiety) among Israeli people living with HIV, and to find predictors for these disturbances.

METHODS

VaLidated neurocognitive tests and psychiatric assessment questionnaires (PHQ-9 and STAI) were conducted among 57 asymptomatic HIV-1 positive patients. Sociodemographic and clinical characteristics were collected from the patients' files.

RESULTS

The rate of disturbances in the neurocognitive test was dependent on the test used. Whereas in Trail making A and B (TMA, TMB) high rates of disturbances were found, almost no patients with disturbances were found when the digit symbol substitution test (DSST) was used. In immediate and delayed memory testing (IMT and DMT) 47.7% and 49% memorized less than 75% of the numbers, respectively, while 18% of the patients had anxiety and 24% suffered from depression. The median quality of life measured by the analog scale was 7. In multivariate analysis we could not find predictive variables for neurocognitive or psychiatric disorders.

DISCUSSION: Neurocognitive disturbances and psychiatric disorders are common among asymptomatic people living with HIV, irrelevant of the time of being positive, immunoLogical status, viral load or treatment received.
