Psychiatric presentations of non-HIV infectious diseases. Neurocysticercosis, Lyme disease, and pediatric autoimmune neuropsychiatric disorder associated with streptococcal infection.

Infectious diseases can cause an array of symptoms, including psychiatric symptoms. Psychiatrists serving the medically ill need to be aware not only of classic infectious diseases (e.g., neurosyphilis and HIV), but also of less commonly discussed infectious diseases (e.g., NCC, PANDAS, and Lyme disease). These examples represent an internationally endemic disease (e.g., NCC), a probable immunogenetic disease (e.g., PANDAS), and a frequently overdiagnosed and overtreated disease (Lyme disease).
