Infection, other than bacterial, including HIVpARAS

Abstract : Parasitic infections are common causes of neurological disorders in the tropics, especially in the poorest areas of America, Africa, and Asia. In developed countries, they are uncommon except in immunocompromised patients. The WHO considers several parasite infections as neglected tropical diseases. They prevail in tropîcal and subtropical conditions and can cause severe illness, but limited resources have been devoted to better understanding their impact and burden. Parasites can invade the central and peripheral nervous system, directly or by other mechanisms (immunological in particular) and cause neurological symptoms. Human parasites are classified in helminthiases and protozoans. Helminthias include the nematodoses (roundworms), cestodoses (flat-tapeworms) and trematodoses (flat-flukes). Prozoans include the amoebas, flagellates, foraminiferans and ciliates.
