Using MRI to see mental illness in the brain
Canada Foundation for Innovation backs 14 U of T researchers
What is going on in the brain of a person who has a severe mental illness, such as schizophrenia or bipolar disorder?
Aristotle Voineskos knows that treatment for these difficult conditions can’t be improved until a clearer understanding of the relationship between genetic factors and brain circuitry is achieved.
And to do that, Voineskos is making important progress in using Magnetic Resonance Imaging (MRI) techniques to map brain regions, connections and networks to learn how the brain is wired in health and in disease.
Voineskos has been awarded $287,849 to take his research further from the Canada Foundation for Innovation’s John R. Evans Leaders Fund (JELF). The fund, which has just awarded a total of $3,134,307 to U of T researchers, helps universities and hospitals acquire infrastructure for researchers to pursue cutting-edge work. JELF is named for Dr. John R. Evans, former U of T president.
“The combination of brain imaging and genetics can identify genetically susceptible brain circuitry common and unique to schizophrenia, bipolar disorder and psychotic depression, which can then be translated as treatment targets,” says Voineskos, a professor in the Department of Psychiatry at U of T and clinician-scientist at the Centre for Addiction and Mental health (CAMH), where he is the Koerner Scientist, and Head of the Kimel Family Translational Imaging-Genetics Laboratory.
In his work, Voineskos is also testing new treatments for cognitive dysfunction in these disorders, where he is using brain imaging to predict treatment response.
“There is a fundamental need to improve our understanding of existing treatments and develop new treatments for these disorders, especially related to cognitive deficits present in all disorders with psychosis and for which there are no treatments currently available.”
