Images in the top row show activity of the default mode network (a major brain network supporting cognition) in rugby players after a season of play. They show hyperactivity of the network. The bottom row shows the same network for swimmers and rowers who had the same season of competition, but are non-contact athletes. The default mode network appears normal.

Resiliency and concussion: Why do some athletes develop neurodegeneration and others don’t?

Concussion is considered a ‘mild’ injury, but effects can last a lifetime, especially with multiple impacts. Understanding their long-term effects can help predict who might develop neurodegeneration.

Mitochondria keep your brain cells alive − helping them run smoothly may protect against Parkinson’s disease

As the powerhouse of the cell, mitochondria lie at the intersection of many essential biochemical pathways. When they go awry, neurodegenerative diseases can result.

A promising new study could lead to a reduction in symptoms of amyotrophic lateral sclerosis (ALS)

A new study shows that it is possible to reduce the symptoms of amyotrophic lateral sclerosis by reducing the inflammation caused by immune cells in the brain.

Newly discovered genetic variant that causes Parkinson’s disease clarifies why the condition develops and how to halt it

No treatments are currently available to cure Parkinson’s disease. Better understanding the genetic foundation of this condition can help researchers find ways to slow or halt its progression.

Chronic wasting disease has been detected in British Columbia deer, and we need to act now

B.C. has operated a surveillance program for over 20 years to detect chronic wasting disease, a fatal condition with no cure or vaccine. The disease has now been detected in deer in the province.
The experimental methods available today allow us to break the brain down into its elementary components in order to understand its functions and dysfunctions. (Shutterstock)

The Douglas‑Bell Canada Brain Bank: a goldmine for research on brain diseases

Montréal is home to one of the world’s largest brain banks, the Douglas-Bell Canada Brain Bank, where discoveries about different neurological and psychiatric diseases are made.

Alzheimer’s disease is partly genetic − studying the genes that delay decline in some may lead to treatments for all

Despite decades of starts and stops, new treatments and key genetic discoveries are giving researchers great hope for slowing or eventually preventing Alzheimer’s disease.
