Antiretroviral drugs may help prevent neurological decline in individuals with HIV infection by suppressing viral replication and associated chronic immune activation in the central nervous system. However, HIV control in the brain may come at the price of drug-induced neurotoxicity. Herein, we review recent advances in the balance between adequate viral suppression in the nervous system and adverse effects of the medications used in HIV treatment.

Fungal infections of the central nervous system have manifold presentations and courses that depend largely on both host and organism characteristics. Although subjects with impaired immunity are generally at higher risk for severe disease, several fungal organisms are considered primary pathogens and can also cause disease in otherwise immunocompetent individuals. Herein, we describe the epidemiology, presentation, diagnosis, and management of central nervous system complications of several fungal pathogens.
