We examined the effects of HIV on the structure of cerebrovasculature and the interactions among HIV infection, brain tissue volume and cerebrovascular structure. Decreased cerebral vessel volume, vessel length and branch number were found in people with HIV. HIV related gray matter loss was found caused by the decreasing vessel length. Additionally, decreasing vessel distribution in left insula was found in vessel probability atlas in people with HIV, which may relate to various clinical symptoms.
