Toxoplasma gondii is a widespread protozoan parasite infecting approximately one third of the world population. After proliferation of tachyzoites during the acute stage, the parasite forms tissue cysts in various anatomical sites including the Central Nervous tissue, and establishes a chronic infection. Clinical spectrum normally ranges from a completely asymptomatic infection to severe multi-organ involvement. Many studies have suggested T. gondii infection as a risk factor for the development of some neuropsychiatric disorders, particularly schizophrenia. During the last years, a potential link with other neurobiological diseases such as Parkinson disease and Alzheimer disease has also been suggested. This review will focus on neurobiological and epidemiological data relating infection with T. gondii to neuropsychiatric diseases. (C) 2015 Elsevier B.V. All rights reserved.

Toxoplasmosis is a widespread infection, with clinical spectrum ranging from a completely asymptomatic infection to multi-organ involvement. After entering the body, the parasite forms tissue cysts and establishes a chronic infection, involving also the central nervous system (CNS). During the last years, a lot of research has focused on the possible link between exposure to T. gondii and development of neuropsychiatric disorders such as schizophrenia and Parkinson's disease (PD). If a firm association between Toxoplasma infection and neuropsychiatric disorders will be established, this would lead to novel strategies for their prevention and treatment. We will review data from serological and neurodevelopment studies relating infection with T. gondii to such neuropsychiatric diseases.
