The interface of the Liaison Psychiatry with Infectiology is fundamental for the continuous and specialized support of these patients. Prevalent psychiatric records are known in the HIV infection, such as anxiety, depression and abuse and/or addiction to substances. There are also different neuropsychiatric situations associated with this infection owing, namely, to the HIV direct action on the central nervous system, to the adverse effect of the antiretroviral therapy and to the resurgence of existing prior pathology.
