Research supports toxoplasmosis link to schizophrenia

Dr McConkey says: "It's highly unlikely that we will find one definitive trigger for schizophrenia as there are many factors involved, but our studies will provide a clue to how toxoplasmosis infection - which is more common than you might think - can impact on the development of the condition in some individuals.

"In addition, the ability of the parasite to make dopamine implies a potential link with other neurological conditions such as Parkinson's Disease, Tourette's syndrome and attention deficit disorders, says Dr McConkey. "We'd like to extend our research to look at this possibility more closely."
