Sleep disruption research by UHN’s Dr. Tatyana Mollayeva shows the impact on recovery from brain injury, cognitive reaction

Behind the Breakthrough

In the latest episode of UHN podcast Behind the Breakthrough we feature KITE researcher Dr. Tatyana Mollayeva, who talks about her pioneering research on sleep disruption and its impact on patients with neurological disease and brain injury. Her research, for example, reveals a connection between a patient’s ability to recover from mild traumatic brain injury and sleep disruption, and, she’s been able identify risk factors such as adverse cognitive reactions and loss of reaction time in people with mild TBI who have sleep issues. Dr. Mollayeva also speaks to her role as an educator, and, advocacy work promoting sleep health awareness, including with the World Health Organization where she has pushed for the inclusion of sleep as integral to brain health.

And Dr. Mollayeva reveals her inspiring journey to becoming an award winning research scientist, beginning at age 16 after graduating high school in her hometown of Novyi Rozdil , Ukraine when she left to study the sciences and earn a medical degree in Moscow. In the early 1990s, she fled the collapsing Soviet Union to Turkmenistan, where she met her husband. After stints in Wyoming and then back to Turkmenistan, Dr. Mollayeva and her family were accepted in 2003 to come to Canada under the Independent Immigrant Program. In her 2022 acceptance speech upon receiving a prestigious Canada Research Chair, Dr. Mollayeva paid homage to all immigrants who take the risk of leaving their homeland to seek new opportunity.

“As an immigrant, this award is not just for me. It is for all immigrants who have a passion and take the often frightening step of changing their professional identity.”
