This research study seeks to learn about the brain, moods, memory, thinking and concentration in healthy adults and compare them to those who have HIV infections. Researchers will evaluate the relationship among brain inflammation, protein function and MND; and how HIV infection may cause problems with blood vessel function and contribute to thinking and mood disorders, such as early dementia and depression. Researchers will compare persons with and without HIV infection.
