Season 3 · Episode 9

Tuesday, July 9, 2024 • Duration 39:31

At UHN’s Krembil Brain Institute, we have cared for many patients living with an extreme and heartbreaking facial pain disorder called trigeminal neuralgia. Patients often describe the pain as a lightning bolt to the face, or an electric shock. Some talk about the impact the disease has had on their family & relationships, including not being able to hug their loved ones, or kiss their children goodnight.

In today’s episode, we discuss how AI is helping researchers look for patterns and clues to treat patients living with trigeminal neuralgia and other chronic pain disorders.

Featuring:
Dr. Mojgan Hodaie – Neurosurgeon and senior scientist with UHN’s Krembil Brain Institute and the Greg Wilkins-Barrick Chair in International Surgery at UHN.

What Women Need to Know About Stroke Prevention & Recovery

Season 3 · Episode 7

Tuesday, June 11, 2024 • Duration 46:51

A stroke happens when there is a sudden blockage of blood flow to the brain or bleeding in the brain, which can result in symptoms such as numbness or weakness, trouble speaking, confusion, or dizziness. The type of symptoms one might experience depends largely on the type of stroke, and the area of the brain affected. But one thing is clear – despite the many advances in stroke care over the past 30 years, it's women who often suffer the most. 

In today’s episode, we discuss why women are more susceptible to stroke, what the unique risk factors are, and what women need more of to help them recover, not only from the medical condition, but the impacts to their careers, their mental health and their families.

Featuring:
Dr. Aleksandra Pikula, MD, PhD, is a neurologist and clinician-investigator at UHN’s Krembil Brain Institute and the newly appointed Jay and Sari Sonshine Chair in Stroke Prevention and Cerebrovascular Brain Health at UHN. Dr. Pikula advocates for a holistic approach to brain care, specifically targeting stroke and dementia prevention during midlife through evidence-based lifestyle medicine pillars.

Are Reading Disabilities Genetic?

Season 3 · Episode 6

Tuesday, May 28, 2024 • Duration 42:15

Do you know a child who has difficulty spelling or sounding out words? Maybe they feel stressed or anxious when it comes to reading, or they try to avoid it altogether?

These symptoms could be a sign of a reading disorder, which is the most common form of a learning disability.

In this episode, we discuss the prevalence and impact of reading disorders, what scientists are learning about the genetic links, and what that could mean for new approaches and treatments in the future.

Featuring:
Dr. Cathy Barr – Senior Scientist with UHN’s Krembil Brain Institute and the Hospital for Sick Children. Her research focuses on genetic links to neurodevelopmental disorders, such as childhood depression, Tourette’s syndrome, ADHD and reading disabilities. Dr. Barr’s team has identified genes that may contribute to these disorders. They’re now focusing on understanding how those changes in DNA could influence genes, and contribute to risk.

Dr. Maureen Lovett – Senior Scientist Emeritus in Neurosciences and Mental Health at The Hospital for Sick Children, where she founded and directed the hospital’s Learning Disabilities Research Program for more than 35 years.

Erasing the Stigma of Neurofibromatosis

Season 3 · Episode 5

Tuesday, May 14, 2024 • Duration 29:08

Have you ever heard of a genetic condition called neurofibromatosis, also known as NF?

It’s one of the most common genetic disorders, affecting about 1 in 3000 people globally. NF causes different types of tumours to form in various parts of the body. Because so little is known about the condition, it’s often misdiagnosed, or not diagnosed at all.

UHN is home to the Elisabeth Raab Neurofibromatosis Clinic, the only adult NF clinic in Canada. We discuss the clinic and the exciting research happening in the field of NF. But, for many people living with the condition, the stigma is often as challenging as the illness.

Featuring:
Dr. Suganth Suppiah – Surgeon-scientist at UHN’s Krembil Brain Institute and Assistant Professor at the University of Toronto. Dr. Suppiah also leads the nerve surgery program at the Elisabeth Raab Neurofibromatosis Clinic, Canada’s only adult NF clinic, based at UHN.

Dr. Ryan Thomas – Family physician and Clinical Associate who works with patients at the Elisabeth Raab Neurofibromatosis Clinic. Dr. Thomas lives with neurofibromatosis himself.

25 Years of Momentum in Spinal Cord Injury Research

Season 3 · Episode 3

Tuesday, April 16, 2024 • Duration 40:18

In 1995, actor Christopher Reeve was injured in a horseback riding accident, leaving him quadriplegic - paralyzed from the shoulders down. He became a tireless advocate and a passionate supporter of research.

Christopher’s dream was for those living with spinal cord injuries to have a better quality of life, and one day to walk again.

More than 25 years later, thanks to advances in surgical approaches, neuroprotective drugs, and gene therapy using stem cells, that dream is becoming closer to reality.

Reduce Your Chances of Alzheimer’s. Here’s How.

Season 3 · Episode 2

Tuesday, April 2, 2024 • Duration 35:04

In the time that it takes to say this sentence – three seconds – someone in the world will develop dementia, a group of symptoms impacting memory, thinking, mood, behaviour and the ability to complete everyday tasks. Alzheimer’s is the most common form of dementia.

With people living longer, even into their 90s and beyond, dementia is becoming the biggest and most consequential global health threat of our time. But, according to a landmark study in The Lancet medical journal, there are 12 modifiable risk factors that can reduce your chances of getting dementia at any age – by up to 40%.

In this episode of Your Complex Brain, we discuss which of those risk factors are most impactful to lower – or even reverse – your risk of dementia, with a focus on the latest science looking at the benefits of exercise.

Featuring:
Maria Martinez has been a social worker nearly 25 years. Most recently, she has worked with the team at UHN’s Memory Clinic, helping patients living with Alzheimer’s and dementia, and their families, navigate their diagnosis and community supports.

Dr. Carmela Tartaglia is a Neurologist and a Clinician Scientist with UHN’s Krembil Brain Institute, as well as co-Director of UHN’s Memory Clinic and an Associate Professor at the University of Toronto.

Dr. Laura Middleton is an associate professor and the Schlegel Research Chair in Dementia and Active Living, at the University of Waterloo. She is also an Affiliate Scientist at KITE, the research arm of UHN’s Toronto Rehabilitation Institute.
