Summary
Subtle changes to the brain, which doctors find difficult to detect through conversation or examination, may occur in patients with HIV and/or hepatitis C infection. It is not currently known whether the brain is affected in early (or acute) hepatitis C.

This study plans to evaluate what happens to the brain in patients with HIV and early hepatitis C. The investigators will be comparing 3 groups of individuals:

- Group 1: Individuals with HIV infection and acute (early) hepatitis C infection

- Group 2: Individuals with HIV infection

- Group 3: Healthy volunteers

Individuals wishing to take part will complete a series of tests assessing different aspects of their brain including:

- 2 brain scans using different technology:

- Magnetic resonance imaging (MRI) brain scan with spectroscopy

- CT PET brain scan

- A computer game test which measures brain function

- 2 short questionnaires

Results of these tests will be analyzed and compared between 3 groups.
