Neural Correlates of Working Memory Training for HIV
This research project is a clinical trial to evaluate the efficacy of the computerized working memory training program “Cogmed®”.
Multimodal MRI (sMRI, DTI, functional MRI), CSF cytokines and LMX1A genotypes are used to evaluate and assess treatment effects
We are actively recruiting HIV-positive and HIV-negative individuals.
Funded by NIDA / NIH (7R01-DA035659)
Adolescent Brain Cognitive Development Study (ABCD Study)
The University of Maryland is one of 21 institutions nationwide participating in the ABCD Study. Researchers have enrolled almost 12,000 children ages 9-10 years, whose biological and behavioral development will be tracked through adolescence into young adulthood.
The ABCD Study at the University of Maryland is conducted in the new HSF-III research building and the Maryland Psychiatric Research Center.
Although HIV-infected individuals can be treated and have normal life expectancies, up to half continue to suffer from cognitive problems that are often difficult to evaluate. This exploratory study aims to use machine learning to combine different types of brain imaging and clinical data to generate an objective and reproducible approach to assess brain injury associated with HIV-infection. Our approach may provide a useful biomarker to evaluate brain injury and monitor treatments in these patients in both research and clinical settings.

The goal of this study is to evaluate the efficacy of computerized working memory training program in HIV-positive individuals, using multimodal MRI.

I have a long-standing interest in developing and applying advanced MRI and MRS techniques to study the developing brain in neonates and young children. It is fascinating to observe the rapid and dramatic changes occuring in infants with MRI.
For instance, the image on the left shows early myelination of the motor tract (hyperintense signal) in a newborn, which mirrors the rapid improvements in motor skills in neonates.
