HIV medicines can now suppress the virus to undetectable levels, yet many people living with HIV still have problems with memory, attention and thinking. Women living with HIV carry a larger share of this cognitive impairment.

What they work on

  1. Test which brain pathways, such as neurotransmitter loss, neurotoxic metabolites and nerve cell damage, link chronic immune activation (for example IL-6 and sCD163) to cognitive impairment in about 500 women from the Women's Interagency HIV Study.
  2. Identify how modifiable risk factors, namely depression and substance use, affect immune activation and neurobiological pathway markers, using stored biospecimens and existing behavioral data from three time points.
  3. Examine whether antiretroviral therapy levels in hair, a measure of medication adherence, explain part of the effect of depression and substance use on immune activation and brain pathway biomarkers.

More about the research

Even when the virus is controlled, their immune systems can stay chronically activated, and this ongoing inflammation is a consistent risk factor for cognitive decline. This project asks how that inflammation reaches the brain, and which risk factors that people could change make it worse.

Why it matters

Findings could guide prevention and treatment of cognitive impairment in women living with HIV. Identifying which biological markers drive cognitive decline may point to drug targets such as immune therapies or dopamine reuptake inhibitors. Clarifying how depression, substance use and medication adherence fuel inflammation could shape behavioral interventions, such as mental health and resilience programs, aimed at limiting the inflammation that leads to cognitive impairment.
