This study identifies hippocampal subfield volume differences in PTSD and depression across 31 cohorts, finding depression has a stronger effect than PTSD, especially in CA1, with comorbid cases showing more pronounced changes.

This study finds smaller limbic brain volumes are associated with greater immunosuppression in HIV+ adults across five continents.

The paper uses machine learning to predict neurocognitive outcomes in children with perinatal HIV, identifying key predictors from clinical data with high accuracy.

The paper uses group based trajectory modeling to identify distinct cognitive phenotypes in children with perinatal HIV and finds demographic factors, not HIV-related variables, are associated with lower cognitive trajectories.
