The CogNaive Study: Assessing Changes in Neurocognitive Function in Treatment Naïve HIV-1 Positive Subjects

May 20, 2014 updated by: Imperial College London

A Randomised Prospective Study Assessing Changes in Neurocognitive Function, Using a Computerised Test Battery, in Treatment Naïve HIV-1 Positive Subjects Commencing Two Different Antiretroviral Regimens

The purpose of this study is to investigate the possibility of an association between changes in neurocognitive function, as measured by a computerised test battery, and the use of two different highly active antiretroviral therapy (HAART) regimens in treatment naïve HIV-1 infected subjects commencing antiretroviral therapy.
