Mandana Modirrousta, MD, PhD, FRCPC
Dr. Modirrousta is an Assistant Professor at the University of Manitoba in the Department of Psychiatry. She completed her residency in psychiatry at the University of Manitoba in 2012 before pursuing a fellowship in clinical neuropsychiatry at Massachusetts General Hospital, Harvard Medical School. Prior to her residency, Dr. Modirrousta earned a PhD in neuroscience from the Montreal Neurological Institute at McGill University and completed post-doctoral training in cognitive neuroscience and behavioral neurology. She is certified in the subspeciality of Behavioural Neurology and Neuropsychiatry by the United Council of Neurologic Subspecialties.

Dr. Modirrousta is the director of the Neuromodulation and Neuropsychiatry Unit at St. Boniface Hospital, where she uses neuropsychological and neurocognitive tools as well as repetitive transcranial magnetic stimulation (rTMS) to study the link between the brain and behaviour in a variety of neuropsychiatric disorders. In 2010, she received the Association of Chairs of Psychiatry in Canada research award and the American Psychiatric Association award (Research Colloquium for Junior Investigators). She also received several best presentation and best paper awards during her residency at the University of Manitoba.

One of Dr. Modirrousta’s main research interests is understanding the mechanisms of compulsive behaviours in Obsessive Compulsive Disorder and Frontotemporal Neurocognitive Disorder. She applies rTMS as a possible treatment intervention for these conditions. In addition, her lab is investigating biological signatures of rTMS treatment-response in neuropsychiatric disorders including depression.

Her clinical interest is exploring the concept of ‘cognitive rehabilitation’ – through cognitive training and rTMS therapy – in a variety of mild to moderate neurocognitive disorders including post-concussion syndrome and the early stages of neurodegenerative disorders.
